2018 Chevrolet Tahoe Problems & Complaints

Was driving approximately 45MPH and the truck just slowly powered down and "Engine Power Reduced" and eventually cut off and wouldn't crank back up. Got it towed to the Chevrolet dealership and was told the engine has to be replaced due to the bottom of the motor and the crankshaft in cylinder one. Was told it would be 17k to repair it.

Transmission failed at 94,000 miles Misfire 80,000miles AFM/DOD issues $10,000 in repair bills still not fixed

Unknown, vehicle starts to jerk when shifting gears. Jerks when breaking and when accelerating. Check engine light on. I see there is a prior recall for the same issue on same year as mine

For several months my check engine light has been flashing when I’m driving, especially on the highway. At times my vehicle feels sluggish. I press further own into the gas pedal and I am not getting adequate propulsion. It also feels like this when I’m going up a hill. I brought the vehicle to two independent service centers to get a diagnostic. One indicated getting misfire readings on two cylinders. The other indicated getting misfire readings in three cylinders. As you would imagine this is an extremely concerning safety risk.

Roof racks have deteriorated due to sun exposure and have cracked where the contact the top and started leaking. The paint on the roof and hood had also failed. I had to have the top and hood repainted prior to having it ceramic coated. The roof racks leaking have damaged the headliner in the cargo area. I have tried to reseal them with a silicone sealant since removing them or replacing them is too expensive and would require removing the entire headliner to access the connecting bolts.

The contact owns a 2018 Chevrolet Tahoe. The contact stated that in 2024 the front windshield was damaged, and the windshield was replaced. The Insurance Company was notified and requested that an aftermarket windshield be placed on the vehicle. In May of 2025 the contact noticed that the Chevrolet Assist Camera behind the rearview mirror had failed. The vehicle was taken to the dealer, who determined that since the windshield was not an OEM windshield replacement, the part caused the camera to fail. The camera was unable to be calibrated. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 82,000.

The contact owns a 2018 Chevrolet Tahoe. The contact stated that while attempting to start the vehicle, the brake pedal had to be depressed very hard to start the vehicle. The contact stated that while depressing the accelerator pedal, the vehicle failed to respond as intended. A dealer was contacted. The vehicle was taken to the dealer where it was diagnosed and determined that the brake vacuum pump was not operating correctly and needed to be replaced. The vehicle was not repaired. The contact related the failure to a Special Coverage Adjustment: N182202780 (Brake Assist Decreased Due to Vacuum Loss); however, the VIN was not included. The manufacturer was notified of the failure, and referred the contact to the NHTSA Hotline to report the failure. The failure mileage was 72,000.

The Body Control Module does not work. A new BCM was installed in my car in April 2025. Since then I am having multiple issues, but the safety related issue is with the trailer braking system. It is available for inspection upon request. The dealership is unwilling to try another BCM without it costing me $600 for labor. If I am unable to use my brakes, then I put myself and others on the road at risk. The problem started with a Tire Monitor System. I was told I needed a BCM to fix the problem so the car would not throw codes. Now, I am being told the problems with the brakes are not comiing from the BCM. THERE WAS NOTHING WRONG WITH MY car until I took it to this dealership for a new key faub and a tire pressure monitor error. The Body Control Module in a 2018 Chevy Tahoe Premier does play a role in controlling the sunroof. More specifically, the sunroof system is supplied power through a fuse located in the driver-side fuse box which is connected to the BCM. The sunroof switches communicate with the BCM via a serial data circuit, and the BCM then commands the sunroof to open or close. Therefore, the BCM acts a central hub in the electrical system of the vehicle and communicates with the sunroof control module to operate it. I learned this from two other dealerships. One dealership in West Virginia and another dealership in Texas told me this information about the BCM controlling the sunroof and many other electrical parts of the 2018 Chevy Tahoe Premier. To make it simple, the BCM was replaced. The vehicle is now having serious issues. I consider an unintended activation of the braking on the wheel which causes the vehicle to pull to one side puts me at risk of a crash. Is this yet another failed sensor or part due to the negligence of the service department at Smith Buick when replacing the BCM and programming a key faub?

Transmission failure at 110,000 miles. No warning lights, no codes. The transmission was slipping during acceleration, random rpm bouncing at a steady speed, acting lost in gears, slow power up hills then takes off. Currently sitting at a chevy dealership.

The contact owns a 2018 Chevrolet Tahoe. The contact stated that while starting the vehicle, the engine made abnormal rattling and knocking sounds. No warning light was illuminated. The vehicle was taken to the dealer, who determined that the camshaft and valve train needed to be replaced. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the VIN was not included in the recall. The manufacturer was made aware of the failure and advised the contact to file a complaint with the NHTSA Hotline. The failure mileage was approximately 90,000.

Complete Engine failure due to the camshaft being destroyed. Dealership said it was due to the lifters.

Manufacturing problem, but not listed under recent GMC recall of April - May 2025 - 2018 Chevy Tahoe Problem: Transmission Issue - slippage

The contact owns a 2018 Chevrolet Tahoe. The contact stated that while driving at an undisclosed speed, the vehicle began to shake excessively, prompting the contact to discontinue driving the vehicle. The check engine warning light was illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the transmission. The vehicle was repaired, but the failure reoccurred. The manufacturer was not notified of the failure. The failure mileage was 80,000. The VIN was not available.

Transmission is overheating and forcing the truck into limp mode

Transmission suddenly locked up while driving. Took to dealership and was advised it was a chronic issue with my vehicle. Once inspected by dealer, was advised that engine lifters also went out. My car was just out of warranty with 55k miles. Dealer did not want to honor warranty and charged me 15k in repairs. I reached out to Chevy and they provided me with some assistance by knocking off 3k. I did not get any warning lights indicating that there’s an issue with the engine or transmission. It happened suddenly. I feel that there is an engineering issue with the transmission and engine. The mechanic checked in my vehicle and said to me that this was a persistent issue with Tahoes like mines. I feel cheated by Chevrolet.

The contact owns a 2018 Chevrolet Tahoe. The contact stated while driving 35 MPH, the vehicle inadvertently lost motive power. The contact was able to pull over to the shoulder of the roadway, where the vehicle was restarted. The ABS and check engine warning lights were illuminated. The vehicle was towed to the dealer, who diagnosed a failure with the crankshaft push rods, resulting in damages to the engine. The contact was informed that the crankshaft and the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 83,000.

The contact owns a 2018 Chevrolet Tahoe. The contact stated that after parking the vehicle in a parking lot and returning to start the vehicle, the “Power Steering Assist Fault” message was displayed, and the vehicle was difficult to turn to the right or the left. The contact left the vehicle in the parking lot and after returning to the vehicle later and starting the vehicle, the vehicle had regained power steering assist functionality. The vehicle was taken to an independent mechanic who diagnosed the vehicle and determined that the 12-Volt battery needed to be replaced. The contact was advised by the mechanic that due to the weak battery, the power steering assist failed to operate as designed. The vehicle was repaired. The contact stated that several weeks later the power steering assist failure recurred. The contact stated that the "Power Steering Assist Fault" message was displayed. The vehicle was taken to another independent mechanic. The vehicle had not been diagnosed or repaired. The contact researched online and related the failure to NHTSA Campaign Number: 21V455000 (Steering); however, the VIN was not included. The manufacturer was not informed of the failure. The failure mileage was approximately 84,000.

Vehicle stopped accelerating while coming up to speed from an on ramp to the interstate while traveling from Indiana to Florida. Vehicle was towed to the nearest Chevy dealership where we were told the engine had blow and would need replaced. Vehicle has been sitting on the same dealership in Florida since early July. My families lives were put at risk as we were traveling at a low rate of speed on the interstate. As well as, sitting on the side of the interstate in a remote area waiting for a tow truck and cab. The dealer has confirmed what happened via inspection. There were not warning lamps until we lost the engine.

4100 Miles - Asked service dept. at dealership to check for noise coming from underside of vehicle. No service was completed. 4800 Miles - Asked service dept. at dealership to check again for noise on suspension. Service indicated it was a parking brake cable that was rubbing. 9800 Miles - Asked service dept. at dealership to check fluttering noise coming from engine. No service was completed. 15,000 Miles - Asked service dept. at dealership to check again for rattling noise coming from engine. Service indicated fluttering heard was exhaust pulsing through the manifold. No service was completed. 21,000 Miles- Service Dept at dealership provided multi point inspection and given clear inspection. No service was completed even though I stated there was still engine noises. 24,000- Asked service dept. at dealership to check hard shifting from transmission and poor performance. In addition, mentioned the noises again. No service was completed, service stated it was due to colder temperatures. 25,000- Asked service dept. at dealership to check hard shifting from transmission and poor performance. In addition, mentioned the noises again. Engine cooler lines were replaced. Scanned and verified clutch learn values all normal. Activated TCC and disabled TCC and found normal operation. No service completed. Now, after warranty has expired, service at dealership is telling me my camshaft and lifters need to be replaced, struts are leaking, transmission needs attention and should be flushed, and that I should NOT be driving my vehicle due to safety concerns. Although, I had taken the vehicle in multiple times during warranty period with complaints about these very items, no service was ever completed to correct them. Since then, I have read multiple articles documenting GM issues with L87 6.2L engines and transmissions. I'm filing a formal complaint with GM, as these issues should have been communicated to consumers or fixed through recalls.

I can smell gas inside my cabin and also when parked in garage. Mechanic said my fuel injector seals are leaking and this is a known issue . The safety bulletin 18-NA-137 November 2019. This is a SAFETY ISSUE and needs to be addressed for the safety of myself and others. Please issue recall immediately so I can get fixed.

Like every other GM vehicle from 2014 to 2021, the tongue converter has failed and ruined the crappy transmission.

The contact owns a 2018 Chevrolet Tahoe. The contact stated while driving at an undisclosed speed, the brake pedal was depressed with the brake warning light illuminated. The vehicle was able to restart; however, the failure recurred. The vehicle was taken to the dealer where it was diagnosed that the vacuum pump had failed and needed to be replaced. The vehicle was repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 92,104.

Brakes failed pedal went to the floor when getting off the interstate. Kept pressing pedal and came back but vehicle pulls to the left hard when Brake pedal is also very hard to press. Very unsafe afraid to drive the vehicle. Dealer has recalls for same model vehicle show under my vin . Vehicle is available for inspection at anytime.

First occasion the car drove fine with no indication of an issue. Then once the car was turned off then on, the dash showed no lights or gauges and indicated that the steering assist is not working and the wheel was impossible to turn (almost like a limp mode but not driveable). Disconnected the battery to try and clear the issue and car drove home fine. Was told it could be a bad battery so replaced the battery and it worked fine for about a month. Then again with no indication did it again and this time it cleared itself after about 30 minutes. Dealer said there was a short in the negative battery ground cable and an open circuit in the rack and pinion mechanism but that the rack and pinion part was not available and they weren’t sure when it would be (probably due to excessive failures). Replaced the negative battery ground part and everything was fine for about 3 months until today when the car did the same thing again. We will have to keep looking for the unavailable part or I will basically have a $30k paper weight. Very concerned at the possibility that the steering will go out while I am driving as others have mentioned in previous posts. Seems as though something tragic will have to happen before they issue a recall of a part that appears to be a common failure.

My 1.5 year old daughter is able to press the button on the chest clip and release the chest clip by herself. The button barely requires any pressure to be applied before releasing. She is unbuckling herself frequently.

9-19-23 Vehicle stalled and started sputtering when turned on.

12-11-23 Vehicle was not accelerating when pressing gas pedal then began violently shaking and shut off in middle of roadway.

7-21-23 Unit stalled 3 times today. The last time was while driving. Check engine light on. 1-29-24 Today I was responding to an emergency backup for an officer that was fighting two subjects. The subjects were fleeing from a stolen vehicle and it was dispatched that these subjects were armed. I never made it to this call because my vehicle #10688 would not accelerate past 23mph and then shut off leaving me stranded in the roadway. While waiting for a tow truck I was able to get the vehicle started again and was able to drive at only 36mph to try to get to the scene and assist the officer. I ultimately was able to make it to the police station. I wrote up the vehicle and left the keys in the training building.

The repeated failure of the fuel pumps, despite replacement three times, poses a significant safety concern as the vehicle may not start immediately, potentially leading to issues while on the road. This delay in starting could result in the vehicle not running properly, potentially shutting off unexpectedly, which poses a danger to the safety of the driver and others on the road. Additionally, the uncertainty surrounding the effects of using E85 fuel, despite the vehicle being sold as flex fuel, raises concerns about the long-term viability of the motor and overall vehicle performance. It's imperative to address this issue promptly to ensure the safety of all road users and preserve the longevity of the vehicle's components.

When I started car I got service messages for side detection system, tire monitor system, safety restraint system, front camera system, trailer break system and theft deterrent system. Each one gave option to dismiss. When I would dismiss the messages would come back. When I was driving, all the things on dash, mph, oil, battery etc all stayed on zero. Super dangerous and I could have died!!!!!!. No blinker sound

My vehicle started announcing service trailer brake system when i purchased my vehicle about 5k miles in i took it to the dealer they couldn't find anything wrong now that message started to get worse not only is it a safety concern due to the annoying beeping. Sound on the dashboard indicating something is wrong. It makes me take my eyes off the road it Constantly distracts me every time it goes off. Also, feel every time that message appears. My truck slows down. As well, a safety concern when pulling a trailer. The brake system could fail on the trailer due to trailer brake assist malfunctioning.

AC stopped blowing cold air due to a broken condenser weld issue commonly found in previous recalls 2014-2017

Caliper became stuck which produced smoke coming from tire. Had the caliper replaced. Then months later my forward collision system activated because a car in front of me stopped abruptly. After the car automatically braked to slow my car down, the brake never released and became stuck and the ABS light came on. Replace the abs sensor and two days later the brake engaged on its own while doing 60 mph on the highway. Now whenever the hill assist, collision warning, or anything else is activated, the brake engages and gets stuck. In addition, at times on the highway my brake will engage on its own.

I had an accident in this vehicle where the airbags deployed upon impact (as they were designed). However, once airbags deployed, my vehicle was filled with smoke (from the airbags) and all of my windows were covered and I couldn't see out. Panic set in as I tried to get out of the vehicle and my door would not open. After several moments I thought about the door locks, they were engaged of course. Once I realized and hit unlock, the door opened. This isn't an issue as far as parts being a defect or anything like that, but today I heard of a Texas DPS Trooper being in an accident in his Tahoe. His took a front impact as well, and the person trying to help him couldn't get him out of the vehicle. It made me wonder if his locks were engaged too, and him being more severely injured may not have thought about the door locks. This could be a potential safety risk, especially if the vehicle is on fire. What if vehicle manufacturers were able to install a safety mechanism that would automatically release the door locks if an impact was detected, or air bags were deployed? Just merely a suggestion as none of the parts on my car failed, they all did their job, but not being able to get out of your car is terrifying. I'm not sure if I am in the right place to pass on this suggestion, so if not, please advise where I might leave one. Thank you.

On 7/27/2023, the transmission in my 2018 Chevy Tahoe failed. There was no warning, noise or lights I dicating a problem. I was trying to excelerate after turning at a stop light. There was a slight hesitation when shifting so I let off the gas. When I tried again, it didn’t do anything and I began losing speed. I had to have the vehicle towed to the dealership. Upon their inspection the tech determined internal failure inside transmission. I was told I was 3,000 miles out of warranty.

As we are doing a three hour drive our vehicle keeps distracting me from driving. Trailer brake system message pops up in the dash board constantly. Like the whole system electric turns off while driving. Few times it turnoff completely while me still driving my vehicle.

A/C condenser replacement. GM previously admitted problems with 2014-2017 AC condenser in certain model years of trucks and suv. The recalls should be extended to later years. I recently replaced AC condenser on 2018 employer owned Tahoe with typical crack and weld areas. Today, having same part replaced on my personally owned 2018 Chevy Tahoe. GM obviously has a defective part thousands nationwide are complaining about. The is obviously a defect GM should recall and replace at their expense.

The Trailer Brake System Service light and ding constantly go off while doing standard driving without any type of towing involved. I have never used a trailer on the vehicle; however, the ding and service light are a distraction and cannot be turned off.

Power steering went out with kids in the car when vehicle only had 76000 miles. There was a special coverage for 2018 models that my vin was not a part of. Had it been this wouldn't have happened to my family. I was without a vehicle for over 2 weeks since dealership had to reach out to GM to find the part. Apparently, this is big issue for other models and years which explains the part shortage. A few months prior there was a service power steering on my dash, and I couldn't turn my steering wheel. Took it to dealership and they brushed it off as computer issue. Again, I feel if my vehicle was part of the special coverage, I wouldn't have experienced this issue or had to pay over $2000 to repair it.

I was sold a vehicle from a dealer in Arizona that online says they only sell to government or law enforcement

The contact owns a 2018 Chevrolet Tahoe. The contact stated that while parked on a slight incline and shifting into reverse, the vehicle started driving down the driveway with the brake pedal depressed. The contact stated that the vehicle drove approximately 15-feet in reverse. The contact stated once on a flat service, the vehicle suddenly stopped. During the failure, the message "driving assist" was displayed. The failure had occurred on another occasion. The cause of failure was not yet determined. The local dealer was notified of the failure. The manufacturer was not yet contacted. The failure mileage was approximately 54,000.

Purchased brand new Chevy 2018 Tahoe in April 2019. Overall good car never had any issues until 02/08/23 as I was driving a got a service alert "Trailer Brake System", It was so random since we have not hauled anything for that to even become a problem. The next day 2/09/23 the car was not drivable it wouldn't turn on it kept giving me the same alert "Trailer Brake System". I called the dealership and they said it's a defect and have to take the Tahoe in for service since only they can find the defected harness and now I have to pay out of pocket for something that I did nothing wrong, something that is manufacture defect and completely unsafe to drive.

Trailer brake system warning, I can’t drive, because it buzz me off! Never used trailer.

Just driving down the freeway and my sunroof just shattered. We were not driving under anything for something to be thrown or fall on the sunroof and nothing was thrown up from the road.

The contact owns a 2018 Chevrolet Tahoe. The contact stated that while driving approximately 65 MPH, the vehicle decelerated and abruptly slowed down and lost motive power. The check engine warning light was illuminated. The vehicle was towed to an independent mechanic who informed the contact that the SMR lifter and the engine failed. The contact called the local dealer who informed her that the parts were back ordered but the vehicle was not diagnosed or repaired. The manufacturer was notified of the failure but provided no additional assistance. The approximate failure mileage was 104,163.

While driving home, the the FAC, forward automatic crash, indicator light came on, I applied the brakes and watched to my dismay as my vehicle slowed down but would not stop. I applied steady hard pressure until impact with another vehicle in front of me. The FAB, forward automatic braking system never kicked in. I will contact the dealer concerning the above issue.

A lifter collapsed, which in turn damaged the lobes of a piston, which then damaged the camshaft...generating a repair bill of $7,100 per the dealer. The vehicle only has 69,200 miles on it. When the lifter failed, the car shuddered at stops, lost some power and made a noticeable clanking noise. When pulling out from stops, or into traffic, the car hesitated somewhat before accelerating. This creates a very dangerous situation. Also, if more lifters or the camshaft seized up at higher speeds, a driver could experience a potentially fatal situation from an uncontrollable vehicle or a fire. Research shows that Chevy/GM knew about the lifter problem on 5.3 ltr engines with their AFM system for years and sold them anyway. They apparently have never solved the problem, and it still exists today. Several class action lawsuits have been lodged against them for the lifter failure problem. Aside from the serious potential safety issues, an expensive vehicle like my Tahoe should not be expected to incur a $7,100 repair bill when it's only 4 years old and has less then 70,000 miles on it. That's ridiculous. My wife and I are both retired. We will be tapping our retirement account to pay for this shoddy Chevy product and will worry that it just might occur again, after the fix. From a safety standpoint, a stall, loss of power, or engine seizure at speed will tax our quick response reflexes. The known lifter problem is a legitimate safety situation and needs to be addressed before someone is seriously injured or killed...if they haven't already. Thank you for listening.

On July 29, 2022 my Tahoe broke down on me while driving home from work. It started to lose speed while on a busy highway during rush hour. I started losing speed and I kept giving it gas and it wouldn’t go. I kept trying to get speed to try and get off the highway to avoid getting into an accident or put someone else in danger. Somehow I managed to get off into a shopping center. I had come up to a stop sign and couldn’t even get the Tahoe to stop while there was a lot of traffic in the shopping center as well. I eventually got it to a safe spot and called a tow truck. I live almost an hour from home. The shop the Tahoe was towed too said the torque converter was contaminated with metal shavings that was caused by parts on the Tahoe grinding together and therefore contaminating the torque converter and then it ruined my transmission. I was also told this is a common thing they are seeing with Chevy Tahoes, but yet no recalls have been issued and I think something needs to be down about it. It put my life in danger as well as other drivers around me! And I couldn’t afford to fix it so I lost my vehicle and all the hard work and money I put into paying my vehicle since 2018! I also found a lawsuit regarding this issue too.

Brake assistance on this vehicle sucks

When applying the brakes the SUV will pull hard to the left or at times to the right. I get a screen message that reads " trailer brake system failure". The SUV has never trailed anything. Also dont know if these are tied together but I'm also experiencing a dragging battery during this time. When the trailer brake says failure goes away the battery issue goes away. I've done some research and have found a GM service call "N192261050" which seems to indicate the same issue/concern.

I have a 2018 Chevrolet Tahoe. Today, while I was pulling out of the Sam's Club parking lot I heard a huge thud, the car jerked forward and completely stopped. The drive line / drive shaft had broken clean off. I'm awaiting official diagnosis from Riverton Chevrolet's service dept., but it was a very scary situation. I'm thankful that I was not rear ended or hurt. I see that welding issues are part of a NHTSA safety issue on later model Chevy Tahoe vehicles. I'm wondering if my 2018 is a victim of a similar problem. I do not drive at high speeds or go off-roading. I get my car serviced regularly. This could have been catastrophic if I'd been on the freeway. Repair invoice pending.

My wife was driving everything was working fine until a message came on the dash "steering stopped Drive with care" she was mid way in a turn to get on highway when this happened if I wasn't in vehicle to grab the wheel my wife would have ended up in a wall or worst case in the canal next to 95 with my 4 year old in the car. The vehicle is currently at a chevorlet dealer in Greenacres Florida and they say the electric steering gear has stopped working.. this seams like a very unsafe system as when it stops the steering wheel is very stiff more than a old car with no power steering. I think this needs to be investigated yesterday as someone could die from this if it hasn't happened already. As of right now I no longer feel that this is a safe vehicle for my wife to be driving

The contact owns a 2018 Chevrolet Tahoe. The contact stated while driving at various speeds, the vehicle stalled with the check engine warning light illuminated on the instrument panel. Recently, the contact had the vehicle towed to a dealer where they diagnosed the vehicle with engine failure. The contact was notified of the diagnosis and the dealer recommended that the engine be replaced. The manufacturer was notified of the failure and the contact was provided a case number. The vehicle was not repaired and remained in the possession of the dealer. The failure mileage was 22,949.

Transmission issues on 2018 Chevy Tahoe. The vehicle stopped on the Hwy. Dealership says the transmission needs to be replaced. Is uncertain why the transmission has gone out on the vehicle since it’s only 4 years old. Error message came on my vehicle and I called the dealership. From my research it appears Chevrolet is continuing to have problems with the transmission on its Tahoes. This is unexceptionable. The consumer has to pay the price not the manufacturer. Please assist.

1- the second row center Seat Belt Receptacle stopped locking so failed, this happened while using the vehicle. 2- the seatbelt receptacle stopped latching while using the car in Seattle, I had to drive with someone in that seat unbuckled because all other seats were being used. 3- the receptacle can not be repaired, needs to be replaced; 4- I have contacted the manufacturer to have them fix this but they will not do it without compensation. 5- no warning. the vehicle is not old and in very good condition. I drive with my family in the car daily but rarely need to use the middle seat. I feel this is a defective latch due to the limited use and age of vehicle. I am concerned that the other seatbelts will also break without warning and Think that GM needs to be aware of a possibility.

The contact owns a 2018 Chevrolet Tahoe. The contact stated that while his wife was driving approximately 35-40 MPH, the power steering assist failed. The failure occurred on several occasions, which nearly caused a collision. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 120,000. The VIN was unavailable.

The contact owns a 2018 Chevrolet Tahoe. The contact stated that while either reversing or stopping, the brake failed to operate as needed The contact stated that the brakes were skipping. The service brake assist and brake assist warning lights were illuminated. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The contact stated that the failure was related to NHTSA Campaign number 19V761000 (Service Brakes, Hydraulic, Service Brakes, Electronic Stability Control) however, the VIN was not included. The manufacturer was not notified. The approximate failure mileage was 84,000.

Steering Wheel hard to turn and locks for a short period when making turns going low speeds. (turning into parking spot or reversing out of parking spot) When steering in reverse, front dashboard shut down and returned in 1 second with a restart. Left in middle of road trying to back into driveway. Car parked and started, car windshield wipers were activated while in garage, radio station was reset & wouldn't allow to be changed, and car gave action required notifications on dashboard (power open & close driver window & passenger window) Park Assist Off light shows after steering issues. Tire Sensors reset Compass recalibrated

Entire vehicle loses electrical power. The vehicle does not shut off, however. Lights, dash, display etc. Possibly a grounding issue. Problem has not been looked at yet, but has occurred twice in the last week. No warning lights available. Occasional park assist failure occurs, may or may not be related.

As I drove the 2018 Chevy Tahoo the brakes got really hard to press and would no longer stop. I was finally able to get it to stop and moved off the road. The vehicle was towed to the AutoNation Chevrolet Mesa Dealership (6330 Superstition Springs Blvd. Mesa, AZ 85206). I was told that the vacuum pump seized causing the brake belt to break. I was told by another mechanic that there is a recall on the hydraulic vacuum pump breaking system....... As the vacuum level drops, the brake assist decreases, increasing braking effort, extending the distance required to stop the vehicle, thereby increasing the risk of a crash. Summary: General Motors LLC (GM) is recalling certain 2015-2017 Cadillac Escalade, 2014-2018 Chevrolet Silverado, GMC Sierra, 2015-2018 Chevrolet Suburban, Tahoe, GMC Yukon vehicles. The amount of vacuum created by the vacuum pump may decrease over time.

My vehicle recently has had 2 issues that I have taken in to the Service Shop for 3 times and the problem has not been fixed. My most concerning issue is my brakes. My brakes are doing the exact problem indicated in this article: https://www.consumerreports.org/car-recalls-defects/gm-recalls-suvs-and-pickups-for-braking-issue/ When the brakes malfunction, I feel a vibrating brake pedal, feels like my vehicle is not going to stop on time, I hear a ticking noise from the engine and my Brake Assist Service light comes on. The issue continues until I can pull over and restart the vehicle. It is a very uneasy feeling having to drive a vehicle that you do not feel safe in. I called 800 Chevrolet's Customer Service number provided in the article and they are unaware of the recall mentioned in this article. I do not know where to go from here. I just want my vehicle fixed and to feel safe. My 2nd issue is regarding my Adaptive Cruise Control. I've had it in the shop 3 times for this also and they did replace a part but that did not fix this issue. I will be driving down the highway or interstate and out of the blue my alarm starts dinging, the seat vibrates, the cruise control gets kicked off and I get an alert on my dash stating that the Adaptive Cruise Control was disabled. Each time it has happened to me there is nothing around but it immediately starts reducing my speed. If someone were behind me it could cause a crash because of the unexpected speed limit reduction. When you go in to look at recalls on 2018 Chevrolet Tahoes it shoes that there is 3 of them that have been issued, yet my VIN is not included in any of them? What can I do from here? I've called Chevrolet's 800 # and they created a "High Urgency Case" but I have not heard back. Attached are my copies of service records and vehicle summary showing there has never been recalls on my VIN #.

The contact owns a 2018 Chevrolet Tahoe. The contact stated while driving 40 mph and making a left turn, the vehicle started hesitating. The steering wheel ceased. There was no warning light illuminated. The contact took the vehicle to the local dealer, where it was diagnosed with needing all four tires to be replaced. The contact replaced all four original tires however, the failure persisted. The contact took the vehicle back to the local dealer, where it was diagnosed with needing an alignment. The contact stated that the wheels were aligned however, the vehicle but continued to experience the failure. The contact stated she had the vehicle serviced four times but continued to experience the failure. The contact also stated that the low brake fluid warning flashed off and on, even after adding brake fluid to the vehicle. The vehicle was not repaired but was pending repairs. The manufacturer had been informed of the failure. The failure mileage was approximately 40,000.

2018 TAHOE W/ 60,000 MILES BEGAN RIDING EXTREMELY ROUGH ANY SPEED. SO MUCH BOUNCE AND JARRING THAT THE CAR IS UNSAFE TO DRIVE ON ANY ROUGH ROAD.

WHEN STATIONARY AND TURNING ON VEHICLE I HAD DIFFICULTY TURNING STEERING WHEEL. I RECEIVED A NOTIFICATION THAT POWER ASSIST WAS NOT ACTIVE. THIS HAPPENED ONCE BEFORE AND I TOOK TO DEALER. THEY CLAIMED IT WAS THE BATTERY AND REPLACED. I SEE THERE HAVE BEEN PRIOR RECALLS ON TAHOE FOR STEERING ASSIST ISSUES.

WE JUST HAD TO SPEND $1,000 TO HAVE THE RADIATOR REPLACED ON OUR 2018 CHEVROLET TAHOE BECAUSE IT WAS LEAKING WHICH ONLY HAS 32,050 MILES ON IT. THE TAHOE HAD A 3 YEAR 36,000 MILE BUMPER TO BUMPER WARRANTY, BUT WE WERE TWO (2) DAYS PAST THE 3 YEAR MARK SO THEY WOULD NOT COVER IT. THE TAHOE ALSO HAS A 5 YEAR 60,000 POWERTRAIN WARRANTY, BUT THE DEALERSHIP SAID THAT THE RADIATOR IS NOT CONSIDERED TO BE PART OF THE POWER TRAIN ONLY THE HOSES GOING FROM THE RADIATOR TO THE ENGINE WERE COVERED UNDER THE POWERTRAIN WARRANTY. IN JANUARY 2019 GM ISSUED SERVICE BULLETIN PI1513F (ATTACHED) FOR 2015-2016 TAHOES FOR THIS EXACT SAME LEAKING RADIATOR ISSUE WHICH STATES THAT THE RADIATOR REPLACEMENT SHOULD BE COVERED UNDER THE POWER TRAIN WARRANTY. THIS IS A KNOWN ISSUE FOR 2017 & 2018 MODELS ALSO, BUT GM HAS NOT ISSUED A RECALL, NOR WILL THEY COVER THE 2017-2018 MODEL UNDER THE 5 YEAR 60,000 MILE POWER TRAIN WARRANTY LIKE THEY DO WITH THE 2015-2016 MODELS.

PASSENGER WINDOW WHEN ROLLED UP IT ROLLS DOWN AUTOMATICALLY. BUTTON HAS TO BE HELD IN THE UPWARD POSITION FOR WINDOW TO STAY UP. HAS ALREADY BEEN SERVICED BY DEALERSHIP.

WHILE DRIVING VEHICLE IT CONSTANTLY REVVS UP UNCONTROLLABLY. ALMOST LIKE IT'S DOWN SHIFTING IN LOW GEAR WHEN MY FOOT IS OFF THE GAS PEDAL.

WHEN ACCELERATING IT SOUNDS LIKE MY VEHICLE IS STUCK IN BRAKE DEGRADING OR IS MAKING THAT DISTINGUISHING NOISE. MY VEHICLE IS IN THE SHOP FOR THE SECOND TIME TO FIX THE SAME ISSUE OF PARK ASSIST, SIDE DETECTION AND FRONT CAMERA SERVICE. WHEN EXPRESSING MY CONCERN FOR THIS PROBLEM OF THE SOUND THE DEALERSHIP SAID LET'S FIX THE SERVICE ISSUES FIRST AS EVERYTHING IS ELECTRONIC. I HOPE MY VEHICLE IS SAFE TO DRIVE.

THANK GOD MY WIFE OR SOMEONE WASN'T DRIVING AT THIS TIME : GOT IN THE VEHICLE, STARTED AND A SERVICE VEHICLE CAME ON.. IT SAID ' POWER STEERING DRIVE WITH CARE '. I COULD NOT EVEN TURN THE STEERING WHEEL. I GUESS A STEERING MODULE OR A SOFTWARE UPDATE IS NEEDED. CALLED LOCAL CHEVY DEALER AND THEY SAID CALL BACK MONDAY. BOUGHT TAHOE BRAND NEW IN 2018, ONLY HAS 22K MILES. I'M STUCK NOT DRIVING THE VEHICLE TILL MONDAY. *TR

STEERING ASSIST IS REDUCED DRIVE WITH CARE MESSAGE CAME UP ON THE DASH WHILE I WAS DRIVING ON A 2 LANE STATE ROAD (HIGHWAY) AND THE CRUISE CONTROL STOPPED WORKING CAUSING VEHICLE TO SLOW DOWN BELOW HIGHWAY SPEED LUCKILY THERE WAS NOT ANY VEHICLES BEHIND US. *TR

I PURCHASED A NEW 2018 CHEVROLET TAHOE WITHIN THE FIRST YEAR THE SUNROOF STARTED LEAKING. I HAD IT REPAIRED THE FIRST TIME IN AUGUST. SECOND TIME IT WAS REPAIRED WAS IN NOVEMBER. NINE DAYS LATER, IT LEAKED AGAIN. I TOOK IT BACK FOR THE THIRD REPAIR AND GOT IT BACK 6 WEEKS LATER. DECEMBER 21 I GOT IT BACK AND IT LEAKED AGAIN THE WORST EVER IN 48 HOURS. PLUS THEY DID DAMAGE TO THE INSIDE OF MY CAR. SOME OF THE DAMAGES WAS CAUSE BY TRYING TO GET THE OLD HEADLINER OUT AND THE NEW ONE PUT IN. WHEN IT RAINING AFTER THE THIRD TEMPT OF REPAIRING IT NOW WATER START DRIPPING WATER OUT OF THE SPEAKER ON TO MY DRIVERS SEAT AND DOWN MY STEERING WHEEL ON TO MY HAND. EVERYTIME IT RAINS THE INSIDE OF MY VEHICLE HEADLINER GETS WET. I AM WORRIED ABOUT MOLD AND MILDEW. MOISTURE BEING INSIDE THE CAR. PLUS THE SAFETY OF MY VEHICLE WITH IT HOLDING WATER IN THE HEADLINER.

I WAS IN AN ACCIDENT AN REAR ENDED A PICKUP TRUCK AT 50 MPH CAUSING MY FRONT END TO BUCKLE AND SEPARATE THE ENGINE FROM THE MOTOR MOUNT AND MULTIPLE OTHER DAMAGES. MY AIR BAGS DIDN'T DEPLOY AND THIS IS VERY CONCERNING AND FELT THIS SHOULD BE REPORTED.

OVER THE LAST 6 MONTHS THE BRAKE PEDAL IS HARD TO PUSH AFTER THE TRUCK SITS OVER NIGHT. THE VACUUM BLEEDS OUT INDICATING A VACUUM LEAK IN THE SYSTEM. GM AND THE DEALER SAID THIS MODEL AND YEAR NOT COVERED UNDER CURRENT RECALL.

SERVICE BRAKE ASSIST MESSAGE ON DASH BOARD. THIS YEAR MAKE AND MODEL HAS A RECALL BUT MY VIN# IS NOT SHOWING AN ISSUE THOUGH MY VEHICLE IA HAVING BRAKING PROBLEMS. DEALER SAYS NO RECALL FOR MY VEHICLE. WHY NOT MY VEHICLE? IT IS DEFINITELY THE ISSUE UNDER THE 2018 TAHOE RECALL.

AC CONDENSER LEAK. APPEARS TO BE THE SAME PROBLEM AS 2015-2017 ISSUE THAT REQUIRED GM TO PROVIDE A SPECIAL COVERAGE ADJUSTMENT. REPAIR REQUIRED REPLACEMENT OF CONDENSER AND NEW REFRIGERANT.

MY TAHOE DOES NOT START! THEN IT WILL HOURS LATER, IT HAS HAPPENED 3 TIMES IN 2 DAYS I HAVE TAKEN IT TO A LOCAL DEALER AND THE SAID IT KEEPS STARTING FOR THEM, WE ASKED THEM TO DRIVE IT THEN TRY AGAIN. WAITING TO HEAR! I ALSO HAVE HAD MY RADIO SHUT OFF THEN AFTER 10 MIN WILL TURN BACK ON? I LOVE MY TRUCK, BUT NOT IF I CAN'T DRIVE IT

I PURCHASED THIS VEHICLE FROM JM CHEV IN LUFKIN TX ON OCT 3 2019.DRIVING IT HOME I NOTICED MY HEADLIGHTS WERE NOT WORKING PROPERLY. AFTER TAKING IT BACK TO THE DEALER IWAS TOLD THE HEADLIGHT ASSEMBLY WAS BAD. THE DEALER ORDERED A NEW ONE. IT HAS BEEN 2 MONTHS.I CALLED GM PARTS AND WAS TOLD THERE WERE NO HEADLIGHTS LIKE THIS IN THE USA. NO DEALERS HAVE ANY IN STOCK. THESE ARE THE INTELLIBEAM HEADLIGHTS. IN MOTION ON STATE HIGHWAY.

ON OR AROUND OCTOBER 16 2019 I WAS DRIVING MY 2018 CHEVY TAHOE WHEN THE RADIO STOP PLAYING. I PULLED OVER IN A HOTEL PARKING LOT TURN THE VEHICLE OFF OPEN THE DOOR AND THEN STARTED THE VEHICLE BACK UP. THE RADIO DID NOT WORK. I WENT TO MCDONALD'S TO HAVE BREAKFAST IT WAS ABOUT 30 MINUETS BEFORE I GOT BACK IN THE TRUCK STARTED IT UP AND THE RADIO STATED TO PLAY. I THOUGHT IT WAS STRANGE SO I CONTINUE TO DRIVE 2 DAYS LATER MY CHECK ENGINE LIGHT CAME ON SO I TOOK IT BACK TO THE DEALER TO SEE WHAT WAS WRONG. THEY TOLD ME THAT THEY CLEAR THE CODE AND NOTHING WAS WRONG WITH THE VEHICLE SO I THEN GOT AN OIL CHANGE SINCE THE VEHICLE WAS ALREADY IN THE SHOP. ON NOVEMBER 2, AT AROUND 3:20 MY CAR RPM WAS ON 5 AND THE SPEED LIMIT WAS ONLY 23MPH. THEN THE CHECK ENGINE LIGHT CAME BACK ON. I CALL THE DEALER AND EXPLAIN THE SITUATION AND THE TOLD ME TO BRING IT BACK IN THE NEXT DAY. WHEN I STARTED THE VEHICLE AND PUT IT IN DRIVE THE VEHICLE MADE A HUGE THRUST AS IF I WAS HIT FROM BEHIND. IT'S BEEN A WEEK NOW AND MY VEHICLE IS STILL IN THE SHOP.

I WAS UNLOADING GROCERIES FROM THE BACK OF THE CAR. THE TAILGATE SENSOR UNDER THE CAR SENSED MY FEET AND BEGAN TO CLOSE. THE TAILGATE CONTINUED TO CLOSE ON ME, NOT STOPPING AFTER COMING INTO CONTACT WITH ME AS I QUICKLY DUCKED OUT OF THE WAY.

AFTER BEING STOPPED AT A STOP SIGN OR RED LIGHTTHE CAR SEEMS TO NOT WANT TO GO AFTER YOUR FOOT IS TAKEN OFF THE BRAKE AND PLACED ON THE ACCELERATOR TO NEED TO GO. THE VEHICLE WILL THEN HESITATE TO GO AND THEN ALL OF A SUDDEN JERK REAL HARD AS IF BEING HIT FROM BEHIND RIGHT BEFORE IT DECIDES TO ACCELERATE.

SITTING IN TRAFFIC ON I 95 AND HAD TOTAL BRAKE FAILURE AND BEGAN ROLLING BACK IN TRAFFIC AND HAD USE EMERGENCY BRAKE TO STOP THE CAR TWICE. CANNOT BELIEVE THAT GM IS ALLOWED TO SALE A VEHICLE THAT THEY NOW HAS SERIOUS PROBLEMS AND IS ALLOWED TO PUT MY FAMILIES LIFE AND OTHERS AT RISK OF DEATH.

2ND ROW AND THIRD ROW SEATS HAVE NO CENTER HEAD REST.

THE BRAKE PEDAL IS TOO CLOSE TO THE DRIVER IN RELATION TO THE GAS PEDAL. THE DISTANCE OF EACH PEDAL CANNOT BE ADJUSTED INDEPENDENTLY. A DRIVER'S FOOT CAN BE TRAPPED IN BETWEEN THE TWO PEDALS BECAUSE OF THE GAP. IN A FATAL SITUATION, IT TAKES LONGER FOR THE RIGHT FOOT TO MOVE FROM THE GAS PEDAL TO THE BRAKE PEDAL SINCE THE RIGHT FOOT CANNOT JUST MOVE LATERALLY TO THE LEFT, BUT IT NEEDS TO GO AROUND.

ON THE EVENING OF NOVEMBER 27TH, MY CAR WITH 10,200 MILES HAD MULTIPLE ISSUES MAKING IT UNDRIVABLE. I ATTEMPTED TO PULL MY CAR OUT OF A PARKING SPACE. WHEN I PUT THE CAR IN DRIVE, I FELT A HARD THRUST. THE THRUST WAS SO HARD THAT I FELT LIKE A CAR HIT ME. I ATTEMPTED TO PUT THE CAR IN REVERSE; HOWEVER, IT WOULD NOT REVERSE WHEN I STEPPED ON THE GAS PEDAL. WHEN I PUT THE CAR IN DRIVE, IT BARELY MOVED. AS IT MOVED, I FELT THE POWER STEERING LOCK, AND I COULD NOT MOVE THE STEERING WHEEL. I TURNED THE CAR OFF AND ON THREE TIMES AND ENCOUNTERED THE SAME ISSUES. AT THIS POINT, I WAS STUCK IN THE MIDDLE OF A PARKING LOT IN A ODD PLACE WHERE CARS HAD TO GO AROUND ME. WHEN THE TOW TRUCK ARRIVED TO MOVE THE CAR, THE DRIVER ENCOUNTERED THE SAME ISSUES. HE POINTED OUT THERE WERE NO RPMS ON THE CAR. THE TOW TRUCK DRIVER HAD TO TOW THE CAR FROM BEHIND, AS I WAS STUCK IN AN ODD POSITION AT THE EDGE OF THE PARKING LOT. AFTER TWO WEEKS, MY CAR REMAINS AT THE DEALERSHIP. THE DEALERSHIP STATES IT'S A COMPLEX ELECTRICAL ISSUE. THEY ARE WAITING TO FIND OUT IF GM CAN FIX IT OR WORSE....THEY WILL JUST GIVE IT BACK. I AM BEGGING TO HAVE THIS INVESTIGATED AS I WOULD HAVE FOR ANYONE OR MYSELF TO ENCOUNTER THIS FAILURE WHILE DRIVING.

BACK UP CAMERA HAS ZERO VIABILITY WHILE BACKING UP DURING NIGHT IN DARK AREA WITH RAIN CONDITION.

BACK UP CAMERA HAS ZERO VISIBILITY WHILE BACKING UP DURING NIGHT IN DARK AREA WITH RAIN CONDITION. THE REAR BACK UP LIGHTS DO NO ILLUMINATE ENOUGH LIGHT TO GUIDE THE VEHICLE. THE CAMERA IMAGE IS TOO GRAINY, DISTORTED AND PIXELATED.

FIRST THE FUEL GAUGE STOPPED WORKING ON AND OFF WOULD GO TO E WHEN ON FULL TANK. THEN CHECK ENGINE LIGHT CAME ON DAYS LATER. THEN VEHICLE STOPPED RUNNING WHILE DRIVING, AND WOULD SHUT OFF. ENGINE WOULD START AND DRIVE AGAIN, THEN STOP RUNNING AND SHUT OFF WHILE DRIVING. FIRST TIME I WAS DRIVING ON HWY, THEN ON CITY STREETS. VEHICLE IS IN GM SHOP NOW, AND THEY SAID IT WAS THE FUEL PRESSURE SENSOR. AND THEY ARE REPLACING THE PART.

I OWN A 2018 CHEVROLET TAHOE PREMIERE WITH THE RST 6.2L PERFORMANCE PACKAGE. THIS VEHICLE HAS THE OPTIONAL PERFORMANCE FRONT BRAKE UPGRADE SYSTEM. I RECEIVED THE FOLLOWING RECALL: GM PROGRAM # N182155600, CUSTOMER SATISFACTION PROGRAM #18119 - SPARE TIRE DOES NOT FIT OVER PERFORMANCE FRONT BRAKE KIT. THE VEHICLE HAS A 17 INCH SPARE TIRE WHICH WILL NOT FIT OVER THE FRONT BRAKES WHEN EQUIPPED WITH THE PERFORMANCE BRAKE KIT. THE SOLUTION PROPOSED BY CHEVROLET FOR A FLAT FRONT TIRE IS A DUAL TIRE CHANGE (REPLACE A REAR TIRE WITH THE SPARE AND MOVE THE REAR TIRE TO THE FRONT). THE CHEVROLET DEALER IS TO PRINT AND INSTALL AN INSERT TO THE OWNER'S MANUAL DESCRIBING THIS DUAL TIRE CHANGE. THIS SOLUTION COMPROMISES SAFETY, ESPECIALLY IF THE DUAL TIRE CHANGE HAS TO OCCUR ON THE SIDE OF A BUSY HIGHWAY. IT DOES NOT MEET MY EXPECTATIONS FOR A PREMIUM SUV. CHEVROLET SHOULD PROVIDE A SPARE TIRE (FREE OF CHARGE) THAT WILL FIT OVER THE PERFORMANCE FRONT BRAKE KIT. AN APPROPRIATE SPARE TIRE SHOULD HAVE BEEN INCLUDED WITH THE FRONT BRAKE UPGRADE OPTION. I CALLED THE CHEVROLET CUSTOMER ASSISTANCE CENTER REGARDING THIS ISSUE. THEIR REPRESENTATIVE WAS RUDE AND NO HELP AT ALL. HIS ONLY REPLY WAS THAT I NEEDED TO TAKE THIS MATTER UP WITH MY CHEVROLET DEALER. SO I DID THAT AND THE DEALER CHECKED WITH THEIR CHAIN-OF-COMMAND WITHIN CHEVROLET. THEIR ZONE REPRESENTATIVE STATED THAT THERE WAS NOTHING ELSE THEY COULD DO OTHER THAN PROVIDE THE OWNER'S MANUAL INSERT. MY COMPLAINT IS NOT WITH THE DEALER. I DO NOT EXPECT THEM TO PROVIDE AN APPROPRIATE SPARE TIRE AT THEIR COST. A RIM AND TIRE FOR THIS VEHICLE (THAT WILL FIT OVER THE PERFORMANCE FRONT BRAKE KIT) IS VERY EXPENSIVE. MY COMPLAINT IS AGAINST GM AND CHEVROLET CORPORATE REGARDING THEIR UNACCEPTABLE RESPONSE TO THIS PROBLEM.

COLLISION ALERT SYSTEM DOES NOT FUNCTION WITH ENOUGH WARNING DISTANCE ON THE SEAT VIBRATION AND RED FLASH PROJECTION ON THE WINDSHIELD. THE DRIVER ESSENTIALLY MUST NEAR COLLIDE WITH AN OBJECT OR VEHICLE FOR THIS FEATURE TO WORK. THE YELLOW CAUTION INDICATOR IN THE DASH DISPLAY WILL LIGHT-UP BUT THE SEAT VIBRATION AND RED FLASH ON THE WINDSHIELD DOES NOT FUNCTION. CHEVROLET DEALERSHIP INSISTS IT WORKS PROPERLY, I CONTEND IT DOES NOT BASED THE FUNCTIONALITY OF THE PREVIOUS MODEL I OWNED, A 2015 TAHOE. THIS SAFETY FUNCTION ADVERTISED BY CHEVROLET DOES NOT FUNCTION AS INTENDED.

I PURCHASED A 2018 TAHOE 20 DAYS AGO AND AT 45 MPH AND 65-75 MPH I FEEL PRESSURE IN MY EARS WHICH THEN MAKES ME FEEL NAUSEOUS WHICH LEADS TO SEVERE HEADACHES. THIS BUFFERING OCCURS EVERY TIME I DRIVE IT. I HAVE TRIED DRIVING WITH THE WINDOWS DOWN / UP, RADIO ON / OFF. NOTHING CHANGES TO LESSEN THE EFFECTS. I GOGGLED SEARCHED IT TODAY AND FOUND SEVERAL REPORTS AND COMPLAINANTS ABOUT THIS ISSUE BUT BOTH GM CUSTOMER ASSISTANCE AND MY DEALER SAYS THEY NEVER HEARD OF THE PROBLEM. THE PRESSURE OCCURS ON LOCAL ROADS AND HIGHWAY, EVERY TIME BETWEEN THE SPEEDS OF 45-55 AND 65-75 MPH.
