While driving my 2022 GMC Yukon Denali at interstate highway speed, the engine suddenly failed without any prior warning. At the time of the incident, the vehicle had approximately 65,000 miles. There were no warning lights illuminated before or during the failure. The engine immediately began running rough, produced abnormal knocking/ticking noise, and then completely lost power. This created a dangerous situation, as I was traveling at highway speed and suddenly could not maintain speed with surrounding traffic. I had to quickly maneuver out of traffic and safely reach the shoulder to avoid a potential accident. Due to the complete loss of engine power, the vehicle was inoperable and had to be towed from the scene. The vehicle has been properly maintained and has not had any prior mechanical issues. I contacted a dealership, but as of now, the vehicle has not yet been inspected or diagnosed. Based on the symptoms, the failure appears consistent with a lifter-related engine issue reported in similar vehicles. The sudden and complete loss of power without warning presents a serious safety concern.

The engine (6.2L L87 V8) failed at approximately 85,000 miles. The failure was diagnosed as internal engine damage and the engine assembly was replaced. The failed engine is available to the manufacturer through the dealer as part of the repair process. The failure resulted in a complete loss of propulsion at highway speeds on the interstate, requiring immediate deceleration and maneuvering to a safe location, which created a safety risk to occupants and surrounding traffic. The condition was confirmed by a GM dealer using diagnostic procedures, including a Pico scope test, which verified internal engine failure. The engine was replaced under GM safety recall / special coverage related to L87 engine failure. The vehicle was inspected and repaired by an authorized GM dealership as part of the recall remedy. Prior to failure, there were no warning lights or messages. The only symptom was increasing engine noise and knocking from the lower end shortly before the loss of power. Failure occurred during normal driving conditions with proper maintenance. No crash, fire, or injury occurred.

While driving my 2022 GMC Yukon with approximately 150,000 miles, the engine suddenly began running rough and I immediately pulled over. The vehicle had to be towed to the dealership. The dealer diagnosed a collapsed lifter and camshaft damage and recommended full engine replacement at a cost of about 9,450. The vehicle had no prior engine issues and most miles are highway miles. Sudden engine failure while driving creates a potential safety hazard due to loss of power. I am reporting this because I understand there are ongoing investigations into GM V8 engine failures and I believe this failure may be related.

At 27, 000 miles while on vacation, over 1000 miles from home, the lifters and bearings grenaded the motor. The vehicle sat at the dealership for a month waiting for a motor replacement. This could have been much worse as we had just driven through mountains the day before. Had this happened in the mountains this could have been deadly. The engine was replaced, but we have no faith in the new engine as these are failing also. This is unacceptable for any vehicle, let alone an $85,000 Yukon. We have also had several issues with water leaking in from the sunroof also. Gm's solution to me basically missing 3 and a half days of a 7 day vacation was to give me enough gm points to get a free oil change. The dealership was great to deal with, the people I dealt with at GM were not very helpful at all.

Gateway system module failed during the L87 recall service.The major L87 recall (ECM update) is a major, high-load software update that frequently causes the Gateway Module to "brick" or stop communicating during the update process resulting in failed module immediately following the service. (TSB) speak to this, The L87 recall is a safety-critical repair, a failure of a module directly caused by this repair should be covered under a recall warranty or GM warranty. Safety can be affected as warning lights will not work due to this failure. Timeline of events. As soon as warranty service was completed before leaving bay lights were not working like Onstar etc, app wouldnt connect to car, 1-2 hours after leaving service engine light came on in car. Never had an engine light on before. Took back to dealer who said it was a computer issue they corrected it. 2 hours later engine light was back on. My car has been at the dealer since Monday when they called to say the GSM had internal failure and wanted to charge me to replace it despite this internal failure being in response to the warranty service that was provided, There are Technical service bulletins about this issue, this has been a known issue with GM vehicles, My timeline shows strong evidence that the failure is a direct result of the recall repair. There is GM TechLink documentation that these modules can be ruined if the update process creates a high load. GM needs to extend the GSM repair/recall or extend coverage for this repair when this happens. This is just another thing GM is not taking responsibility for.

Vehicle: GMC Yukon Denali Model Year: (insert) Engine: 6.2L L87 Mileage at Failure: 44,000 Failure Date: February 18, 2026 Recall: GM 6.2L Engine Failure Recall (crankshaft/bearing defect leading to propulsion loss) Complaint Summary: Complete engine failure and total loss of propulsion on a high-speed highway on-ramp with my family inside, causing extreme danger and emotional trauma. Full Description: On February 18, 2026, my GMC Yukon Denali experienced a sudden and complete loss of propulsion while we were on the on-ramp to a high-speed, heavy-traffic expressway. The engine failed without warning as traffic was accelerating rapidly around us. My husband, my [XXX] son, and I were all in the vehicle on our way to celebrate my son’s birthday. Instead, the vehicle died in one of the most dangerous locations possible — the merge zone of a busy highway — leaving us stranded with cars coming at full speed. Traffic immediately began backing up for a long stretch behind us. Drivers were honking, yelling, and aggressively swerving because the lane was blocked by our stalled vehicle. The situation felt chaotic and frightening. I genuinely believed we were at risk of being rear-ended at highway speed. We felt helpless waiting for police to arrive to protect us. The emotional distress, panic, and fear for my family’s safety were overwhelming. My son was shaking and visibly upset on what was supposed to be his birthday celebration. None of us felt safe until law enforcement was able to block traffic. After the incident, the dealership confirmed that the failure was caused by the GM L87 engine defect currently under recall and stated that the engine needed to be completely replaced. This sudden stall created a severe safety hazard that could have easily resulted in a catastrophic crash, injury, or worse. It has had a lasting emotional impact on me and my family.

In 2023, the vehicle began exhibiting erratic transmission shifting behavior, including harsh and unpredictable shifts while driving. The vehicle was taken to a GMC dealer for diagnosis and repair. Recently, the vehicle developed additional drivetrain and engine control issues related to the crankshaft position sensor circuit. The vehicle stalled while driving on a highway mountain overpass with multiple vehicles traveling behind me. When the stall occurred, the vehicle shifted into park and would not restart for several minutes. This created a hazardous situation due to loss of propulsion in active traffic at highway speed and limited shoulder space. Following diagnosis, the servicing dealer determined that the engine wiring harness requires full replacement due to internal wiring integrity issues affecting critical engine control signals. The crankshaft position sensor and related wiring are essential for engine timing and propulsion. Loss or corruption of this signal can result in reduced engine power, erratic transmission behavior, stalling, or no-start conditions. The earlier erratic shifting behavior appears consistent with conditions described in GM Technical Service Bulletin 21-NA-149, which identifies engine harness-related causes for drivetrain and shifting concerns. This issue appears to involve degradation or defect within the engine wiring harness affecting engine management and transmission operation. Given that this condition resulted in a highway stall and temporary inability to restart, I am reporting this for investigation as a potential safety-related defect involving loss of propulsion.

The contact owns a 2022 GMC Yukon. The contact stated that the vehicle was consuming an excessive amount of oil. The vehicle was taken to the dealer, where it was diagnosed, and metal shavings were found in the engine oil. The dealer replaced the camshaft and lifters; however, the failure worsened. The contact stated while driving approximately 65-70 MPH, the vehicle stalled and lost power steering functionality. The contact's husband was able to pull over to the side of the road. There was no warning light illuminated. The vehicle failed to restart and was towed to the residence. The vehicle was then picked up and diagnosed by the dealer. The dealer determined that the engine had seized and needed to be replaced. The contact had opened a case with the manufacturer for buyback assistance due to safety concerns. The vehicle was not repaired. The failure mileage was approximately 46,000.

On Star module quit working in our Yukon, which in turn makes it useless to have any of the safety features. On Star and GM know this is an ongoing problem, but no recall has been issued. Neither company will repair unless an $1100 fee is paid. Why install On Star if you know it will malfunction. Since there is a monthly service fee I think they need to make sure the vehicle has the correct parts.

The engine threw a rod on January 23, 2026. The vehicle stranded me on the side of the road. We called the dealership which they came and towed back to the dealership. No dashboard warnings at all. Oil pressure was good. I heard a low tick to begin with then a slight squeaking noise. After the engine locked it was an abrupt halt with the wheels locking up but didn't come to a complete stop. The noise was very loud after that and that's when I pulled off the highway. The dealership checked it out and did find that the motor needed to be replaced. We just had the SUV in the dealership on October 2025 and they found no need for a new motor, just a change in the oil viscosity.

The contact owns a 2022 GMC Yukon. The contact stated that while the vehicle was parked, there was a dripping sound coming from the vehicle, and the low oil warning light was illuminated. The low oil warning light was illuminated approximately every 1,500 miles after an oil change. After each oil change, the level on the oil dipstick was low. The vehicle was taken to an independent mechanic, where an oil consumption test was performed. The mechanic informed the contact that the vehicle was consuming approximately 25 percent of the engine oil. The vehicle was not repaired, and the contact was referred to a dealer for assistance. The vehicle was not diagnosed or repaired. The contact was informed that an additional oil consumption test was needed. The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline for assistance. The approximate failure mileage was 87,000.

I am writing to report a failure of the telematics module in our vehicle. The module stopped functioning without any warning or notification on the dashboard. Our vehicle has only 64,000 miles and has never been involved in an accident, so this failure is unexpected. This issue has resulted in the complete loss of OnStar connectivity, meaning that automatic crash notification would not occur in the event of an accident. Additionally, we are no longer able to remotely unlock or access the vehicle through the app, as all communication capabilities are currently disabled.

On 15-Jan-26 (approximately 5 weeks after the vehicle was serviced for the NHTSA #25V274) while doing highway speeds the vehicle suddenly started huffing and loosing propulsion. After the dealership did their initial inspection found that lifters in at least one bank were damaged. The suddenness, the randomness and severity of this unprovoked failure (I wasn’t towing anything or going uphill) combined by the fact that the dealership previously gave this vehicle a clean bill of health makes me have no confidence in the road worthiness of this vehicle.

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.

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)
