Good afternoon, I am submitting this complaint to report a serious and potentially life-threatening safety issue involving my 2022 GMC Yukon Denali. While traveling northbound on State Road 417 (toll road) in Florida, approaching Exit 45, I was driving approximately 75 mph when, without any warning, the vehicle suddenly shifted itself into neutral. A message immediately appeared on the dashboard instructing me to press the start button, and the vehicle rapidly lost power and began to decelerate in the middle lane of a high-speed highway. This sudden loss of power created an extremely dangerous situation that could have easily resulted in a major collision. Vehicles behind me were traveling at highway speeds, and I had no ability to safely maintain speed or predict the failure. The lack of warning makes this issue especially concerning, as there was no opportunity to take preventive action. After the incident, I contacted OnStar for assistance. The vehicle was towed to Carl Black GMC, where the service advisor confirmed that the engine requires a full replacement. A complete engine failure occurring suddenly at highway speeds, without warning, is not just a mechanical issue—it is a critical safety hazard. This type of failure puts not only the driver but also passengers and surrounding motorists at serious risk of injury or death. It is deeply concerning that a vehicle of this age and caliber would experience such a catastrophic failure. Issues like this must be addressed immediately, as they have the potential to cause severe accidents if they continue to occur without warning. I strongly urge that this matter be investigated thoroughly and that appropriate action be taken to ensure that other drivers are not placed in similar dangerous situations. I was fortunate that my children were not in the vehicle at the time of this incident. The outcome could have been far worse. Please let me know if additional information is required.

I took this vehicle in for the recall that GM had indicated. The vehicle was taken to a GMC dealer and “passed” the PICO test and the oil was changed out as recommended. Two weeks ago, the engine completely seized while driving in the interstate and was towed back to the dealership. I am now waiting on engine replacement after passing their solution. The car has roughly 30,000 miles on it.

Monday, March 30, 2026 my GMC Yukon Denali had already had the recall pico test and was told it passed on September 2025 six months later March 30, 2026, driving to pick up my wife from work a tapping sound coming from the engine started and about a mile down the road from when I first heard the tapping the engine started juttering and the noise got louder like a clunking sound. I had to pull off the road into a gas station and use the OnStar to get assistance the vehicle was towed to a local San Antonio dealership Cavender Buick West they gave me a loaner vehicle the next morning and the day after that Wednesday I was informed that yes they confirmed the engine will have to get replaced so now I am waiting for that. I was told by the dealer it could take up to two months for them to receive a replacement engine and once they receive the engine, it can take roughly for maybe five days for turnaround. I inquired whether the replacement engine isn’t upgraded engine or is it the same engine that has all the problems I haven’t received an answer for that yet. I am awaiting that answer from my service advisor. He said he is looking into that.

While driving on the interstate at highway speed, the vehicle suddenly lost acceleration and stalled. I was forced to pull over. After stopping, the vehicle displayed a message to restart, but it would not start. All electronic accessories (lights, dash, etc.) remained functional, but the vehicle would not shift into drive or neutral. The message “Conditions Not Correct for Shift” appeared. Nearly rear ended, this created a dangerous situation due to loss of power in active traffic and inability to move the vehicle on a 250,000 vehicle per day very busy tollway.

My transmission control valve failed while I was driving causing my speed to reduce on a high speed high. I know longer could go in reverse, about 35mph or above 2nd gear. This is a known issue on the 10 speed transmission for 2022 Chevrolet Tahoe, Suburban, GMC Yukon however my vin number was not included in the recall but it happened to me. This was a terrifying situation and i am so shocked as to why my vehicle was not included in the recall to begin with.

6.2 Liter Engine failed at 34,000 miles. The engine failure was confirmed by Luther Brookdale GMC in Brooklyn Center Minnesota. They said the engine failed and replaced it with a new 6.2L engine as part of the recall. No warning lights, or indication of failure, some very minor noises were coming from the engine. It did not fail on the highway, but at the dealer but could have killed my family if it happened on the highway.

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.

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.
