On May 27, 2026 at around 7:30pm my 2018 GMC Yukon XL Denali engined failed. I was exiting E-470 southwest bound at Gartrell Road in Aurora and the engine started knocking loudly and completely quit. As I rolled to a stop I correctly suspected that the engine seized. It would not turn over, a bad odor was present, and smoke was coming from the top of the motor. It was hard to tell exactly from where because of high wind. All belts looked fine and the Castle Rock GMC dealer I had it towed to later confirmed that the engine is seized. Fortunately I was approaching the stop light and not towing anything so the safety risk from loss of power steering and power brakes was lower than normal highway driving speeds a few seconds earlier.

1.XXX XX— GM Recall Notification (Recall No. N252494000) I received official notification from General Motors of Recall N252494000 affecting my vehicle. I brought the vehicle to [XXX] as directed to have the recall remedy performed. 2. XXX — First Report of Engine Propulsion Issues I reported engine propulsion concerns to Jim Ellis. This was my first formal complaint regarding the performance of the vehicle following the recall remedy. 3. XXX — Oil Type Change Performed by Jim Ellis Jim Ellis performed an engine oil type change, switching to 0W-40 oil, and advised me that this change would serve as the fix for Recall N252494000. I accepted this remedy in good faith. 4. XXX — Low Oil Warning Light Activated Approximately nine months after the recall remedy, and well before the end of the recommended oil life cycle, the low oil warning light activated on my dashboard. This is abnormal and indicative of excessive oil consumption. I returned to Jim Ellis, who performed a fresh oil change and placed my vehicle on a 6,000-mile oil consumption test — an acknowledgment that an oil consumption problem exists. 5. XXX — Active Engine Misfires, Jerking, and Flashing Check Engine Light While operating my vehicle on Sunday, May 31, 2026, I experienced severe engine jerking and misfires. The check engine light began flashing — not steady — which I understand to indicate an active and serious engine misfire event. I was genuinely concerned for my personal safety and immediately parked the vehicle. It has not been driven since. 6. XXX — GM Corporate Case Opened I contacted GM Customer Care and was assigned Corporate Case Number INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2021 GMC Yukon. The vehicle was taken to the local dealer for a routine oil change. While driving, the oil low light illuminated. The vehicle was burning an excessive amount of oil. The local dealer was contacted again, but the vehicle was not diagnosed or repaired. The manufacturer was contacted, who referred to the local dealer. The failure mileage was approximately 149,000.

The vehicle suddenly began vibrating noticeably when idling and at low speeds. About 30 minutes after this started happening a warning lamp lit up. We drove the vehicle about 2 miles to a local auto parts store to get an initial computer diagnosis of the issue. The test resulted in a code of "P0304" which detected a cylinder #4 misfire and recommended a fuel injector replacement. We brought the vehicle to a local mechanic to get the issue further evaluated. After this evaluation, it was determined that the cylinder #4 misfire was related to a lifter failure. The mechanic explained that this situation could possibly have caused more damage, specifically to the camshaft, but that job was bigger than he was willing to take on. He recommended we get the vehicle towed to the dealership for further evaluation. He also informed us that this situation was common with the engine in this vehicle and GMC is aware of it. He directed us to some articles online that elaborated on the potential known issues related to the automatic fuel management (AFM) system and the related engine damage. The vehicle was towed to a local GMC dealership for evaluation. They found the failed cylinder #4 with associated lifter failure and damaged camshaft. We went forward with the repair at the dealership. We asked the dealership about the known engine issues with this vehicle. They acknowledged the widespread issues but informed us that our particular VIN has not been included in any recalls or safety notifications, so we were responsible for the repairs. The vehicle spent nearly 3 weeks at the dealership. One of the parts was on backorder due to a national shortage, which delayed the repair by about one week. That seems to imply that the parts involved in this repair are in high demand, which raises the question of this being a manufacturing/parts issue that may need to be investigated further.

My 2022 GMC Yukon XL with the 6.2L L87 engine was previously subject to NHTSA Recall 25V-274 / GM Recall N252494000 for L87 engine loss of propulsion. The recall was closed by the dealer as “PicoScope Inspection — Engine Passed / Update Engine Oil Type,” with the oil/cap/filter remedy. The vehicle was later brought back to the dealer for engine noise/knocking, check-engine light, and engine oil light/oil warning concerns. The dealer has now confirmed that the dipstick was not picking up oil, the oil level was severely low, the oil condition was severely degraded, and abnormal engine noise was heard. My VIN also shows active GM Special Coverage N252494003 through 1/15/2032 or 150,027 miles. The dealer previously stated that the underlying PicoScope pass data from the recall inspection is no longer available to the dealership after submission. This is not the first oil-related concern. During a prior service visit in September 2025, around the same time the L87 recall was completed, the dealer documented an engine oil low message and an upper oil pan leak causing the low-oil message. I am concerned the L87 engine may be failing after the recall remedy was previously marked complete, creating a risk of engine failure or loss of propulsion while driving. I am also concerned the current engine/oil/noise condition is being treated as customer-pay/out-of-warranty before the root cause is fully diagnosed or reviewed by GM under Special Coverage N252494003.

Engine failure occurred while driving with two children in the vehicle, creating a serious safety hazard. The vehicle experienced a sudden loss of power and stalled completely while in motion, with no prior warning lights, alerts, or messages. Prior to this failure, the vehicle had already failed the GM PICO test related to the known L87 engine issue, and the recommended corrective action was changing the oil to 0W-40 synthetic and replacing the oil cap. Despite that intervention, the engine still failed at approximately 49,000 miles. A sudden complete engine stall without warning while driving created a dangerous situation, particularly with children in the vehicle. This raises concern that the prior corrective action did not resolve the underlying defect..

The contact stated that on several occasions while stopped and attempting to accelerate, the vehicle reversed inadvertently and then jerked forward to accelerate. The contact added that the battery was drained but the failure was not the most important to report at this time. The vehicle was taken to a dealer where it was diagnosed that the starter needed to be replaced. The issue reoccurred the same day. The vehicle was taken to the same dealer where it was diagnosed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure.

I was on the highway heading home with my [XXX] son in the backseat and without warning the engine shut down and luckily we were on the exit ramp and away from heavy traffic. I pulled over to the side and tried to start it again but it won’t even crank. The cabin heater stopped working too, It was -9 Degrees outside that day and we started to freeze, luckily my wife was able to get to us in 20minutes. The vehicle was towed to GM dealership and they confirmed the engine seized and will need a new engine under special coverage N252494003-03. This was after the recall was completed for this vehicle. It had only 61392KMS on it. We live in [XXX] and it gets extreme winters with below -40degree temperatures. It’s a remote area and there is no service on the highway for 200KMS when heading south to city, if this would have happened on the highway with no services and extreme weather we wouldn’t have made it out alive. We are a family of 5 with a [XXX] and a [XXX] and we bought this vehicle after knowing that the engine recall was completed and GM deemed it safe. Unfortunately that’s a lie and GM is putting peoples safety and life at risk. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle drove normally earlier in the day with no major drivability concerns. Later, reverse gear suddenly stopped functioning and the engine would rev abnormally without the vehicle moving properly while in reverse. Shortly afterward, while driving, the vehicle displayed the warning message “Reduce Acceleration – Drive with Care” and began losing acceleration and propulsion. The vehicle would not accelerate normally and later could not exceed approximately 20-35 MPH. The condition created a significant safety concern due to sudden loss of acceleration and propulsion while operating in traffic. The engine RPM would increase abnormally while the vehicle failed to respond properly in drive and reverse. An independent mechanic inspected the transmission and found diagnostic trouble codes P0747, P0776, and P0700 related to transmission pressure control and valve body operation. Inspection also revealed significant metal contamination, sludge, and clutch material inside the transmission pan and filter. Reverse and 2nd gear were determined to be failed/burnt internally. The vehicle was later transported to an authorized GMC dealer for inspection. Dealer confirmed reverse gear would not engage even after adding transmission fluid. Vehicle is currently available for inspection.

First incident April 9 2024 not even a month after purchased. Vehicle dashboard lit up light a Christmas tree all warning lights while driving on highway. Vehicle shook and sputtered and turned off. The vehicle was serviced explanation given was loose spark plugs on a new vehicle. 2nd incident roughly month after recall repair for engine propulsion campaign. February 26 and 27 2026 . While driving the following lights came on Engine failure ,Brake failure , Service Transmission now unable to shift soon. I was terrified because I could not control the vehicle. I had the vehicle towed to the dealership. The answer to the issues was Battery failure. Third incident April 17th 2026 I driving on highway 70 miles check engine light comes on flashes dashboard goes dark. Vechicle sputters and shut down. I restarted the vehicle the warning on the display disappeared and the vehicle restarted. I reached returned the vehicle again to the dealership because the problem resumed slowing down even though I’m depressing the gas. Vehicle is shifting and dragging. Resulting unexpected lurching. My vehicle has been at the dealership since end of April 2026 it remains there currently. My representative stated a code indicating misfiring has appeared 18 times. Also everyday my vehicle keeps saying software update even I installed the update and it says complete. I know GM is not updating my vehicle software everyday. That indicates there is a computer issue as well. My anxiety level is through the roof at this point. I complained before about this same failures in a Cadillac Escalade prior to it lurching forward and crashing. I filed a complaint before February 2024 . There is something really wrong with GM engines and software. I know I’m not the only one experiencing these problems
