Water entered tailgate through drainage hole in tailgate cap. The water then dripped on the tailgate switch causing it to short out. This short circuit caused my tailgate to open and close randomly without pressing any switches or buttons or key fobs. May tailgate has a small ding it it now from where it kept hitting the wall while parked in the garage. I took the truck to the dealership to get repairs done and was charged 308.88 for the tailgate switch and diagnosis that should have been under a recall for this truck. Safety Recall N232426400 Tailgate May Open Unexpectedly issued May 2024. I called the customer service number [XXX] to try and get reimbursed for the repairs and they told me there is no recall on my truck. I had this problem and it clearly states the year, make and model of my truck in the recall, but because my vin wasn't included I'm out of luck? I will attach all the info i have on this matter. Any help would be greatly appreciated. Thanks [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
The tailgate will go up and down when the vehicle is turned off and in park. It will also do this while driving the vehicle. * I notice there has already been a recall for this issue, but my VIN shows NO RECALLS
Service engine light kept coming on the dash, and the code came back to a faulty DEF heater. My truck had a reduced power countdown on the dash indicating the truck was going go to into limp mode after x amount of miles. On warmer days the code would go away and there would be no reduced power. The vehicle was diagnosed at a GM dealership and confirmed the DEF heater was bad, but was notified that there is a bulletin with GM for this issue occurring in many other diesel trucks. My safety was put at risk due to the rapidly changing reduced speed milage, at any point it could drop from 100miles, to 10 miles until reduced speed. This could cause an instant car accident while driving if the truck were to randomly slow down to a speed much slower than the speed limit. IE- driving on the north way (65 speed limit) and having the speed drop to 5mph unexpectedly when you just had over 100 miles to reduced speed.

My 2021 Chevy Silverado 3500 [XXX] Motor began requiring a quart of oil every 3-4 weeks. I took my vehicle to a GM dealer in October 2024 and the stated the couldn't find any issues. Fast forward to December 2024 my motor began reading low compression and saying stop the vehicle. I took the vehicle back and pressured them to find out whats wrong with the truck as I only have 76,000 miles and I have performed all of the necessary maintenance. I even have a Chevrolet Platinum protection plan for warranty coverage. I have gotten the run around for months and I have yet to get my vehicle repaired. After taking my truck to a certified 3rd party the verified that the lifters failed and the motor would likely need to be replaced or rebuilt. The mechanics reported this Information to the Chevrolet warranty company and the stated the refuse to provide and repairs unless I produce oil change receipts or return the vehicle back to a dealership and pay for the dealer to tear the motor down.

Please please please help me Sincerely [XXX] General Motors [XXX] 2021 3500 hd wt 4x4 Case # 9-XXX [XXX] I have a 2021 chevy 3500 lt (dually) Been having issues with a rough idle so I figured to replace the plugs, coil packs and wires as my truck just hit 70,000 miles. After doing the full tune up nothing changed, so I scheduled an appointment with my local chevy dealership. They kept my truck for about a week and never completed the diagnosis. I picked the truck back up and took it to another chevy dealer and the told me after a week or so that I had lifter issues and the truck would probably need a new motor. The truck seemed a little sketchy from the gate in the first 50k miles it consumed oil like it was a ol 250k mile chevy.... the alternator went out at around 50k miles and the fuel efficiency would be 6-8 mpg at best.....

Our tailgate would open on its own intermittingly. We haul our fifth wheel camper and this could cause damage to the RV and our vehicle. There have been recalls on one year older trucks and one year newer but not for the 2021Chevrolet Silverado. A Chevrolet dearlership in Florida looked at it for us. They said cause : checked for codes and bulletins. Found code B153D. Completed circuit check. Also found tailgate hatch out of adjustment. Corrctionj: Rec. replace switch and adjust latch. We were charged $486.05 for this. We feel this should be a recall problem. Please advise.
Tailgate opens by itself. This happened 3 times in 2 hours while the vehicle was parked. I tow a 5th-wheel trailer. If this happens when towing it can cause a catastrophe.
