I had the 25v-274 recall serviced at my GM Dealer and was never provide with any paperwork on the extended warranty that was part of the recall. as you can image, not having anything in writing is a big risk as these engines have been catastrophically failing. GM was supposed to provide a extended warranty and service manual update.

SEAT BELTS
While parked, my [XXX] daughter was in the third-row bench seat. The seat belt became wrapped around her body/neck area. The seat belt entered its 'Automatic Locking Retractor' (ALR) mode and continued to tighten as she moved, pinning her against the seat. The locking mechanism would not release, and the belt became so tight she was unable to breathe. We attempted to manually release the buckle and create slack, but the retractor remained locked and continued to tighten. After several minutes of unsuccessful attempts to free her, we had to use a cutting tool to sever the seat belt to save her life as she couldnt breath, she has brusing where the seat bealt was tighten. The vehicle was stationary in a parking lot at the time. The car has not being inspected , there was not warning.

2022 GMC Yukon AT4 was brought into the dealership for the service recall on the engine. No issues and received the 0W40 "fix". Approximately 4-6 weeks later, I was traveling on the interstate at approx. 75MPH when the truck completely shut down mid-passing with a code stating "conditions for not for shifting" and I was lucky enough to get the truck to the shoulder of the road without being struck by another vehicle as the truck "shifted" to neutral and would not do anything. Once the truck was in park, it shut off and I was unable to get it started again. Received multiple codes (key fob battery needs replacing, battery low, etc.) while stuck on the side of the interstate for several hours until I was able to get it towed (at a charge of $500) to my dealership. It then sat in the parking lot for 3 days for diagnosis pending TAC deciding whether to tear the engine down or replace it. It was determined to meet the recall qualifications and the dealership has ordered a replacement engine and was told they would start at a estimated 4 week repair time but would probably take closer to 6-8 weeks. Dealership has provided a rental at no cost to me but did not refund my towing costs associated with the repair.

2023 Yukon Denali has now broken down twice, leaving myself and my family (husband and children). This last time was on Friday 1/16/26 while we were out of town, the car began malfunction and then we had complete engine failure while drive 70mph down the highway, again, leaving my family stranded on the side of the road, on a busy highway, in an unsafe environment in the winter.

VISIBILITY/WIPER
Vehicle can be completely off and windshield wipers are still going. So you have to pop the hood and pull fuse out. If you want to use them ( it starts raining, dirty windshield) you have to stop pop the hood and put fuse in. Has been in shop almost weekly repaired every part they could possible switch and still not repaired.

The engine has started using large quantities of oil. Not dripping oil, burning oil. I have been doing oil consumption studies with GMC for months now. It burned 7 quarts in 5,000 miles. The dealership tells me it is not part of the current recall on others with the same engine, make and model. It is doing the same thing as what the recall is for and my VIN number should be added to GMC’s recall list and the motor replaced. It is a serious safety issue for me and my children,

NHTSA Team, I am the current owner of a 2021 GMC Yukon Denali (VIN: [XXX] ) with the 6.2L L87 V8. At approximately 148,239 miles, I experienced a catastrophic lifter failure. My mechanic diagnosed a failed AFM lifter and metal contamination, requiring full engine replacement. This is documented under GM Case #XXX. CARFAX revealed that prior to my ownership, lifters were replaced twice (~10,469 miles and ~25,572 miles). The dealership I purchased from did not disclose these prior repairs, as they used an alternative vehicle history check. Only upon this third lifter failure did my mechanic identify this recurring defect. I submit this to NHTSA’s investigation into post-repair failures of the GM 6.2L engines. The pattern shows prior remedies were insufficient. Supporting documents (CARFAX, mechanic report) are available. Please advise if further details or inspection of the failed engine components are needed. Thanks, [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

the Engine started running rough and the engine light came on. The dealer told my wife to drive there in limp mode (~15 miles), she did so on back roads. The diagnostics said that cylinder 7 was not firing and teh fuel injector control circuit was bad. they had to replace the Engine Control Unit.

ENGINE, FUEL/PROPULSION SYSTEM
I have a 2024 GMC Denali that had an engine service appointment in September 2025 for the engine recall where they did an oil change & put in performance grade oil & scoped my engine. Rochester Serra GMC said they sent all the engine pictures to GM and my engine was okay according to them. After that appointment in November my engine light went on and my Denali was leaking oil in my driveway. We took the truck back to Serra GMC Rochester and they replaced the oil filter that they said was defective & an oil change was done after my husband requested that just filling up the oil was not okay. They also told us the engine light didn’t show up on their computer system and it must have cleared out, so nothing was done for that. Today 1/25/26 now about a month later my engine light is back on and has remained on with multiple starts. This is not acceptable and needs to be investigated and I want this escalated. I do not feel comfortable driving my truck with this engine light on with a known engine propulsion recall that has no actual cure. The oil replacement and cap change has done nothing and engine light remains on. I just don’t want to hear the same thing that the computer must have cleared the error code. My engine light is on for a reason and I’m asking for a thorough diagnostic test to be done by a certified technician and a get a valid explanation of why my engine light keeps going on & not just changing my oil or waiting for something catastrophic to happen to me or my family. GM is putting me and my family at risk by saying that my truck’s engine is fine when clearly the engine light keeps repeatedly going on for 3 months in a row now since November 17, 2025.

I purchased a Yukon Denali 6.2L in March of 2022 brand new from Bob Johnsons in Rochester NY. On [XXX] at 12,577 miles the engine went through a catastrophic failure, while driving, the vehicle began to make very loud noises. The vehicle was taken to Bob Johnsons GMC 4389 West Ridge Road Rochester, NY 14626. The repair notes #3 main bearing thrust portion had come apart. The vehicle was out of service from 4/3/2023 to 4/19/2023 for engine replacement. On [XXX] at 50,244 miles on the vehicle, I was driving down a busy highway during holiday traffic and the vehicle went into neutral and would not start, we immediately turned the flashing lights on, unrolled the windows and began to show distress to ensure we were not hit by passing cars. We made it to safety and called Onstar for assistance, on this occurrence due to the vehicle not starting we were unable to get the vehicle back in to the neutral position to be able to roll the vehicle. The vehicle was towed to Bob Johnsons GMC due to the Thanksgiving holiday, the vehicle was brought in 11/28/2025, and deemed to need another engine replacement. On November 28th I called to file a claim with General Motors and was called back by Stephanie on November 29th and was told they would get back to me if they had any options as now this is the 3rd engine replacement. On December 3rd, a new woman called also named Stephanie and advised me they were still undergoing options, as I requested a Buy Back with Trade Assistance. On December 9th, my final call from General Motors advisor Stephanie, I was told I do not qualify for a buy back because I placed too many miles on the vehicle between engine failures. The vehicle was out of service from 11/26/26-12/29/26 for engine replacement. On [XXX] 2 weeks and 4 days after the vehicle going back into service, the engine failed again, only driving approximately 245 miles. I am currently waiting on the 4th engine replacement with no updates. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6

SERVICE BRAKES, ELECTRICAL SYSTEM
While driving approximately 63 mph on a busy roadway, my 2023 GMC Yukon experienced a sudden failure of the brake system, including loss of normal braking capability along with failures of the Electronic Stability Control (ESC) and ABS systems. The vehicle displayed warning messages stating “Brake System Failure” and “Service ESC” and entered a reduced-speed mode. Prior to this incident, there were no warning lights, messages, or symptoms indicating a problem. During the failure, the brakes became largely unresponsive, placing me, my two minor children who were passengers in the vehicle, and surrounding motorists at serious risk of a high-speed collision. After extended deceleration, a minimal amount of braking power partially returned, allowing the vehicle to eventually come to a stop. The vehicle has not yet been inspected by a dealer, manufacturer, police, or insurance representatives, and the issue has not yet been reproduced or confirmed by a service center. The vehicle remains available for inspection upon request and has not been repaired. This incident occurred without prior warning and involved a sudden and dangerous loss of braking capability at highway speed.

STEERING, LANE DEPARTURE: WARNING, LANE DEPARTURE: ASSIST
This has happened twice. Once in November 2025 and then in January 2026. With super cruise engaged while going around a curve super cruse disengages and the steering wheel turns to driving straight. You have about one or two seconds to take control or crash. This happened while driving about 70 mph on interstate I 70 and next on Ohio 122 going about 45 mph. On I 70 it was a gentle curve and on 122 it was a much sharper curve. Super cruse must give a warning that it about to disengage that is much longer than one or two seconds.

Vehicle had already "passed" the GM testing and received 0W-40 synthetic engine oil. Engine failure. Vehicle is currently at the dealership. This event put my family at risk of serious injury and possible death as the vehicle suddenly stopped working while drive on a bust street. Engine failure has been confirmed by the dealership, who have recommended installation of a new engine. There were no warning lamps on the dash at the time of the event. However, there was a loud noise immediately followed by lose of engine power.
