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).

No warning the car made a loud clunk that shook the car. The engine began a severe knock with almost compete loss of power. The dealer confirmed the entire engine had to be replaced. I was told my car passed the PICO test recall and only required an oil viscosity change. There is something very wrong here. These engines are not right. I have handicapped twins and have zero confidence it won't leave my family stranded.
