For vehicles that pass inspection, dealers will add higher viscosity oil, install 6 oil fill cap, replace the oil filter, and update the owner's manual. Repairs will be performed free of charge. Owner notification letters were mailed June 18, 2025. Owners may contact Cadillac customer service at 1-800-333-4223, Chevrolet customer service at 1-800-222-1020, or GMC customer service at 1-800-462-8782. GM's number for this recall is N252494000.

What component or system failed or malfunctioned, and is it available for inspection upon request? The vehicle experienced a malfunction associated with a failed Over-The-Air (OTA) software update affecting electronic control modules. The (ECM), (BCM), and related electronic systems appeared to lose stability during operation. The vehicle attempted to reboot while being driven and displayed multiple system warnings. The vehicle is currently at the dealership and is available for inspection upon request. How was your safety or the safety of others put at risk?While driving, the vehicle began malfunctioning and attempting system reboots. The dashboard flickered, warning lights, and the vehicle exhibited unstable behavior. During a prior event, the vehicle experienced unintended acceleration and abrupt deceleration. This created a risk of loss of vehicle control, particularly in traffic. I have small children in this vehicle, and the unpredictable electronic behavior while in motion posed a significant safety concern. Has the problem been reproduced or confirmed by a dealer or independent service center? The dealership confirmed that a previous event was caused by a failed OTA software update. The vehicle has since malfunctioned again while driving and has been taken back to the dealership for further inspection. The dealership has acknowledged module instability and opened a TAK case with the manufacturer. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle has been inspected by GMC1 dealership. A case has been opened with GM Customer Care. No police or insurance reports. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? 9 days prior to the first major malfunction, the check engine light illuminate. On April 1, the check engine light re-appeared and the vehicle attempted to reboot again while driving.

Months ago I took my car to the dealer for the engine failure recall and they said there were no issues and changed the oil to a higher viscosity oil. Today I was driving and my engine failed while turning onto a busy road and took multiple tries to get started. It finally started and the engine light was flashing. The dealer told me th flashing engine light was bad and to not drive at all. I pulled over and had it towed to the dealer. The engine light stopped flashing. The dealer said they pulled a code on the computer and would look at it. They had my car for a full day so far and have said they can't find an issue. I do not feel safe having my family in this car when the engine can fail and they say nothing is wrong. I am lucky that I wasn't hit at the location it failed at.

Was driving approximately 70 miles per hour on the highway. While driving the vehicle just stopped in the middle of the highway after going 70 miles per hour. Was unable to put car in park. Car just shut off. Four police cars had to surround car due to being stuck in the middle of the highway with my small child in the car. Took an hour to get a tow truck. Being told our engine is now completely shot.

The 6.2L motor in my GMC Yukon failed due to the camshaft and stalled me in an intersection on a highway. Had to shut the lanes down to get towed. Lost all power and couldn’t do anything but sit in the road. Just did a PICO test and it “passed” but failed 3k miles after the recall was done.

On 3/3/2026 during the night-time hours, I was traveling on the freeway in my 2023 GMC Yukon at over 65 MPH when I received a notice from the instrument cluster stating that the battery was low and oil pressure was low. Before I could pull over to a safe location, the Yukon turned off while in motion. My wife and two children were in the vehicle. The Yukon stalled in the number one lane of the off-ramp. I had to remove my children and wife from the vehicle while in the roadway on busy throughfares and in darkness. I attempted to jumpstart the Yukon, but efforts were unsuccessful. The Yukon was towed to the dealership where I purchased it purchased from. The Yukon was returned to my custody on 3/10/2026 stating it was an issue with the battery. While driving the Yukon home it began to bog down and stalled out in-front of my residence as it was being driven by my wife. After arriving home (night-time), I went to check the Yukon, and it started with no issues. I drove the Yukon to see if the errors would occur again. While driving the Yukon on the freeway, the Yukon RMPs indicated close to redline and I received a notification from the instrument cluster stating to turn the vehicle off (traveling at about 70-75 MPH). Once again, I was unable to pull off to a safe location before the Yukon turned off on its own while still in motion; I attempted to jumpstart the Yukon but attempts were unsuccessful. The Yukon was towed again to dealership. On 3/11/2026 I was advised that the engine had seized and on 3/13/2026 I was advised by GMC the engine needed to be replaced (this was covered under powertrain warranty). The approximate milage of the vehicle is at about 42,200.

My 2023 GMC Yukon Denali with the 6.2L V8 suffered a sudden loss of propulsion while traveling at approximately 70–75 mph on the highway with my wife and young daughter in the vehicle. The engine RPM dropped immediately to zero and the vehicle displayed a message instructing me to press start. I do not recall any meaningful prior warning lamps or symptoms before the failure. I did not hear a loud bang or other dramatic engine noise; the vehicle simply lost power and would not continue driving under engine power. I had to coast across lanes/shoulder to a stop, which created a serious safety risk to my family and other drivers because the vehicle lost propulsion at freeway speed without warning. After stopping, the vehicle would not restart. Pressing the start button produced only a click from under the hood and the engine would not crank. The vehicle was towed to a GMC dealership in Victorville, California. The dealer has since confirmed that the engine requires full replacement. The failure has therefore been confirmed by an authorized GMC dealer and the vehicle should be available for inspection through that dealership/manufacturer if requested. This is especially concerning because this vehicle was already part of the known GM 6.2L recall population and had supposedly passed the recall inspection/remedy before I purchased it. Despite that, the engine still failed catastrophically only about 1,355 miles into my ownership. Purchase mileage was approximately 26,343 and failure occurred at approximately 27,698 miles. Based on what the dealer told me, the failed component/system is the engine assembly.

I just survived a terrifying incident that proves the current GM 6.2L (L87) engine "recall fix" is a dangerous myth. Living with the "Ticking Time Bomb" I bought my 2023 GMC Yukon AT4 brand new, but for the last two years, I haven't truly "owned" it—it has owned me. Every long-distance trip with my family was filled with anxiety. I constantly worried that I’d be the next one stranded on the side of the road while my neighbors' and friends' 6.2L engines were seizing all around me. I traveled with fear that I’d be coming home in a rental car. The False Security of the Recall When the recall finally arrived, I thought the nightmare was over. On Sept 15, 2025, my dealer in Newburgh, NY, inspected the truck at 48,000 miles. They told me my engine "passed," switched the oil to 0W-40, and issued me a 150,000-mile extended warranty. I realized then what I know for sure now: 0W-40 oil is a band-aid, not a cure. GM used thicker oil to "cushion" a physical manufacturing defect in the crankshaft and bearings just to avoid the multi-billion dollar cost of engine replacements. They traded my family’s safety for their bottom line. The Catastrophic Failure Last Friday, March 13, 2026, the "fix" failed. I was traveling 70 mph uphill on I-84 with my **newborn baby** and two other kids in the back. Without warning, the engine seized solid. I lost all propulsion in heavy traffic and had to fight to get my children to the shoulder. We sat in the freezing cold for over an hour while traffic flew by us. An extended warranty is worthless when your engine dies in a high-speed traffic lane with an infant in the car.

On September 4, 2025, I brought my 2023 GMC Yukon Denali in for the product safety recall regarding the engine. My engine passed the recall inspection and I was given an oil change with high grade synthetic oil. This past Saturday, March 7, 2026 as I was driving in Tampa Florida with my [XXX] son, my Yukon experienced catastrophic engine failure and I lost all propulsion control. The car went into neutral and I pulled along the side of the road safely to avoid an accident. As I put my car into park, the engine shut off completely and would not turn on again. There was no clicking sound and no attempting to turn over. I contacted roadside assistance and they sent a towing company to bring my Yukon to Century Buick GMC in Tampa Florida. The symptoms of what happened are similar to those of the recall. The dealership is replacing the engine however this is a critical safety issue as my son and I could have been severely hurt and or killed. Please investigate.

Vehicle developed hesitation. Message: "Reduced Acceleration Drive with Caution" Check Engine light comes on, fortunately near home. Scanner showed "PO 0747 Transmission Valve #1 stuck open." Research shows this is a common problem and a safety issue and can leave driver stranded or worse. Had vehicle "serviced" at selling dealer, but they did not touch the transmission. Said they drove it around the block and it was fine. Image attached. I was then told that parts are not available and GM will not authorize swapping out the valve body. Forums posts show a lot of dissatisfaction with GM over this issue.

The engine failed and had to be replaced with less than 70,000 miles on it. There has already been a recall associated with these vehicles where a part is either replaced or special oil has to be used. It does not seem that the fix prevents the engine from failing.
