# Formal the federal safety agency Safety Complaint **2022 GMC Yukon — Catastrophic 6.2L Engine Failure, Sudden Loss of Power at Highway Speed, and Inadequate GM Response** I am filing this formal safety complaint regarding the catastrophic failure of the 6.2L V8 engine in my 2022 GMC Yukon, which has approximately 59,000 miles. The vehicle is associated with GM's 6.2L engine safety recall N252494000 (the federal safety agency 25V274). ### Sudden Engine Failure at 75 MPH — Serious Safety Risk While traveling approximately 75 miles per hour on the highway, our GMC Yukon experienced a sudden and complete engine shutdown **without any advance warning**. There were no indications that the engine was about to fail. The vehicle unexpectedly lost engine power while we were traveling at highway speed, creating an extremely dangerous situation for everyone in the vehicle and potentially for surrounding motorists. **Our family, including three young children with special needs, was placed at serious risk because of this sudden and unexpected engine failure.** The incident occurred approximately 70 miles west of [XXX], leaving us stranded in approximately 90-degree weather. We were also towing a trailer containing essential medical equipment required by one of our children with special needs. The sudden engine failure created an immediate highway safety hazard, followed by the additional concern of being stranded in extreme heat with medically vulnerable children and essential medical equipment that we could not transport with our disabled vehicle. ### GM's Failure to Assist With Medically Necessary Equipment Following the breakdown, we contacted General Motors for assistance. Despite explaining that our trailer contained medical equipment necessary for one of our children's care, GM would not assist us with moving the trailer. I find this response extremely concerning. Our family was already dealing with a frightening and potentially dangerous situation caused by the sudden failure. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA

Sudden catastrophic engine failure during operation. Was climbing a hill and suddenly started losing power, almost instantly a written warning popped up on my screen saying engine oil over temp, idle engine. We started pulling off the road, engine started rattling, then shut off before we could come to a complete stop. At this point i was checking the gauges and all were at normal operating temperatures, but as I sat there watching the temperature gauge began to rise rapidly with the engine off. The engine was seized and had to be towed.

On XXX, I was driving my 2022 GMC Yukon XL Denali equipped with the 6.2L L87 V8 engine, with my [XXX] stepson as a passenger, when the engine malfunctioned and stalled, leaving the vehicle disabled in traffic. The vehicle registered diagnostic trouble code P0016 (Crankshaft Position–Camshaft Position Correlation, Bank 1 Sensor A). Prior to this incident, the vehicle had undergone GM's L87 Engine Loss of Propulsion Safety Recall 25V‑274 (GM Campaign N252494000). The vehicle passed the required engine inspection and was cleared to receive the prescribed oil viscosity change from 0W-20 to 0W-40. Under GM's recall service procedure, vehicles displaying P0016 during the inspection were required to be quarantined rather than proceeding with the oil-change remedy. Therefore, the completion of the prescribed remedy indicates that P0016 was not identified during the earlier recall screening. Despite passing GM's engine inspection and receiving the recall remedy, the engine subsequently experienced a failure involving P0016 and a complete loss of propulsion. This raises significant concerns about whether GM's inspection procedures and oil viscosity remedy adequately identify and prevent engine failures in affected vehicles. While our Yukon was disabled in traffic due to the engine stall, another motorist failed to stop and struck the vehicle from behind. The collision caused extensive damage, and the vehicle was subsequently declared a total loss. Although the other driver failed to stop, the engine failure was the initiating event that left our vehicle stranded and exposed to approaching traffic. At the time of the collision, I was [XXX] pregnant and required ambulance transportation, emergency medical evaluation, head imaging, and fetal monitoring. I subsequently experienced post-concussion symptoms and a mandibular-joint injury. My [XXX] stepson was also inside the vehicle. Vehicle can be held for inspection w/letter sent.

I know an engineering analysis has been opened on the 6.2L motor for GM models. I just want on the record that my wife has a 2022 GMC Denali XL that had the engine replaced in December 2025. After that motor replacement it repeated the same issue July 4th 2026 and the dealership replaced the engine a second time for the same reason, and I will be attaching each invoice for both replacements. Just want to have the #'s updated to show the remedy doesn't seem to work or in my case it didn't and I have seen numerous news articles talking about this.

While driving in passing lane on interstate highway at approximately 65 mph engine lost power. Dashboard warning "vehicle in neutral" message appeared. "Press start" message appeared. Tried to start the engine but did not start. Slight downhill while on highway and had to make it to right shoulder since no shoulder on left side of highway. Glided across 2 lanes to right lane and luckily an exit came up while still gliding slightly downhill. Exited ramp and got off highway to an empty parking lot. Put vehicle in Park. Since engine failed, power steering was normal as was all electrical components. Once stopped, vehicle was not able to be shifted into Neutral. Message " unable to shift to Neutral under conditions " appeared. Vehicle had to be towed with rear wheels on dollies since it was stuck in Park. Was very lucky to get vehicle across lanes of traffic and off highway to a safe location. Had vehicle towed to nearest GMC dealership where it was diagnosed as internal engine failure covered under recall for this particular engine. (6.2 liter).

We took in our Yukon for the recall letters we’ve received in the mail and to check a suspension light the popped up. Our Yukon was given back to us with the ac not working properly anymore and it started to turn off on us out of nowhere. now we need an engine replacement. What’s more aggravating is that the Yukon was checked out the week of july27 -31 according to service advisor the engine was good and the only thing needing to be replaced was the module for the suspension light that popped up. Now it turns out that it doesn’t even need a module replacement and the suspension issue is something else. Super frustrating It’s our only family vehicle and it so upsetting that we were given the Yukon back in the condition it was in. Thank goodness the Yukon shut off at a drive thru and not a freeway or my husband would’ve got into an accident.

The engine in my 2022 GMC Yukon XL equipped with the 6.2L L87 V8 experienced a sudden loss of power while traveling at interstate speed. The vehicle had previously received the GM L87 engine recall remedy. Despite the recall being completed, the engine failed, leaving me and my family in a dangerous situation. The vehicle is currently at a GMC dealership and is available for inspection upon request. The sudden loss of engine power on a busy interstate created an immediate safety hazard. Traffic was traveling at highway speeds, and the vehicle rapidly lost the ability to maintain speed, increasing the risk of being struck from behind or being involved in a serious collision. My family was in the vehicle at the time, making the incident especially concerning. The GMC dealership has confirmed that the engine failure is related to the L87 engine issue and advised that the repairs will be covered under the applicable warranty/recall-related coverage. Additionally, after the original recall service was performed, an expanded recall was added to my VIN, further indicating that the original remedy may not have fully addressed the underlying defect. The vehicle is currently being inspected by the authorized GMC dealership. Prior to the engine failure, there were no warning signs indicating an imminent catastrophic failure. The recall service had already been completed, leading me to believe the vehicle was safe to operate. The engine nevertheless failed after the recall remedy, raising concerns that the corrective action may not be sufficient to prevent future failures
