Vehicle went into limp mode. 36 check engine codes popped up all related to cam shaft and lifter issues. Vehicle was taken to a shop and it has been determined that the passenger side lifters and rollers have sized due to the active fuel management system. This is the L86 GM 6.2 liter motor, that has developed the same issues that the L87 motor is being investigated for. There where no tail tail signs or check engine lights that were on prior the the lifter failure.

On 12/5/24 took the truck to the dealership where we bought it with a complaint about the transmission. They took for a test drive could not find anything wrong with it, recommended we have the transmission flushed and filter replaced. They could not do the service so we got it into our local Chevrolet Dealership who did the work for us on 12/6/24. On [XXX] as we were departing a gas station in Tifton, GA, the transmission would not shift out of first gear and the temperature rose up to 234 degrees. Limped the vehicle to a campground, called a transmission shop who told us to bring in the truck at 7:30 am o 1/2/25. They were able to replace the transmission on 1/3. We had to drive it 500 miles before we could continue on our journey to Florida. Trying to accelerate on the Interstate and not being able to significantly put us at risk of a crash. Once the temp rose on the transmission the check engine light also came on. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

After coming to a complete stop at traffic stop light truck's transmission made a loud "clunk" sound. When attempting to accelerate on the green light truck, initially would not move then it lerched forward but would not shift out of first gear. Pulled off main road and into a parking lot where I shifted truck into park and turned off the engine. After waiting a couple of minutes I restarted the truck, shifted into drive and pulled back onto the street, but the truck still would not shift out of first gear.

On friday november 6th we were on our way home coming down 1960 east when we started to hear a noise coming from the truck. We could hear it loud and clear because the A/C is also out so we have been having to leave the windows down. It sounded like an old electric fan running. Then shortly after the truck started to jerk hard it felt like we had just been in an accident. The truck would not shift gears and we were in the middle of a very busy 1960 lucky we were close to home and where able to make it there after multiple attempts to get the truck going. My husband has some knowledge of cars and realized it was the transmission. This is a fairly new vehicle. How can it have such a major problem? When doing some research apparently this is problem that gm is aware of and have done nothing to fix. As I mentioned before the A/C condenser has a major leak and this is also a problem of gm vehicles. Basically we bought a brand new lemon. I'm thankful we were not on the freeway when this happened it could have been much worse outcome. For now we are with out a vehicle and can not afford to replace the transmission.
