On July 4, 2026 while driving with my family up a two lane state road headed to the lake cruising 55mph the engine blew and locked up with no warning, no check engine light or anything causing me to almost wreck and leaving me and my family stranded in a dangerous situation for a moment. I drive out of town just about everyday for work so my truck is set on cruise control most days through the week making multiple long distance trips a month so the mileage racked up fast for me causing me to go right over my warranty when this happened so I can’t get any help with it. Even knowing the issue right now with the 6.2 they will do nothing.

While driving on the freeway with my family in the middle of a snowstorm, my 2025 Silverado 1500 with 8,000 miles on it, suddenly dropped gears down to 1st without warning. The check engine light went on and I later found out it was the valve body that caused it. This could have cause serious harm to my family had I not maintained control of the vehicle. The dealership fixed the problem only for it to happen again a month later. The truck is still in the shop.

I have had my vehicle to a GM dealership three times now due to the check engine light coming on and getting an emission warning. 2/13/26 was the first visit. It was right after I filled up my tank with gas that the check engine light came on when I started driving down the road. I got an appointment at a GM dealership. They put the scanner on it and received the codes. They drove it back to the service garage and I went back to work. I received information from them that they could not fix anything because the check engine light had disappeared and there were no codes available anymore. I picked up my vehicle and a week later 2/20/26 the same thing happened after I got gas. The check engine light came on and an emission warning on my Chevy app. I stopped back into the same dealership. And the same thing happened. Scanner, codes, and then they disappeared. The third time I got gas the same thing happened again with the check engine light and emission system warning. This was on 2/28/2026. I went to a different dealership and the exact same thing happened..... scanner, codes received, schedule an appointment to get it in the following week, started the vehicle and pulled out. The check engine light was still on at that time. And the check engine light disappeared once again as I was driving down the road. Each time this has happened I have been able to use my remote start via my Chevy app along with trying to use my handheld key fob remote start. The dealerships have told me this is normal for this type of check engine light emission warning. When researching this issue there are a lot of people experiencing the same thing. Scratching my head wondering why there's not a recall on this.

Driving 30 mph down a city street when heard a pop and vehicle completely lost power at speed. Engine turned off and I coasted to a stop, which was unfortunately at an intersection and due to traffic could not get over safely. All accessories were still on however I could not restart the vehicle or put the vehicle into neutral, which left me stranded in the middle of a busy intersection. Hazards were working intermittently, at best. Had to call local PD to provide traffic control while we disconnected the battery and reconnected it while standing in an intersection. After I was able to get the vehicle restarted it had a check engine light and the OnStar app showed Transmission, Ignition, and Engine Electrical warnings. Had the vehicle towed to the dealership, where they have had it for 7 days and cannot diagnose an issue and are trying to return the vehicle to me unfixed. They stated they typically would not even try to diagnose it for this long, however I have a case open with the GM executive team.

I was driving under normal conditions and the vehicle began lurching, limiting acceleration, with an error saying "reduce acceleration". Was able to get home but the next time the truck was started there was a check engine light and the vehicle was unable to shift into reverse gear. When attempting to put it into reverse, it gives the error "conditions not correct to shift" and turn on the parking break. Trying to drive it with this issue is unsafe. The truck will lurch, limit acceleration, and overall not safe to drive. The truck only has 21k miles on it.
