The contact owns a 2022 GMC Sierra 1500. The contact stated upon accelerating and driving at approximately 5 MPH, the vehicle violently jerked. The vehicle began to drive as designed, but the failure recurred. There were no warning lights illuminated. The vehicle was taken to the local dealer, who test-drove the vehicle and experienced the failure, but the vehicle was not diagnosed or repaired. The failure mileage was approximately 52,000. The VIN was not available.
The engine failed while driving on the expressway. It is clearly the fault of the Active Fuel Management (AFM) system but GMC will not honor the warranty because I went over 7,500 miles between oil changes. This is a problem because the car stopped operating while driving down the interstate. Manufacturer inspection took place. They looked at the oil filter and saw the metal in the oil filter. No warning lamps, messages or symptoms of any sort prior to the engine failure.
The transmission became inoperable and a message appeared on the display 'Engine Power Is Reduced' in area of the highway where the speed limit is 55 and then the transmission failed completely and left the engine revving at high rpm and not moving the vehicle forward and we rolled to the side of the road to a stop. This was a very dangerous situation as traffic was flying past us and had to move out of the way of our coasting vehicle. It was towed to a GMC dealership about 8 miles away as it is still under warranty. I've read many stories in GM forums about problems with this GM 10 speed transmission in this pickup truck. This needs to be looked into as a potential recall as this problem left us stranded on the side of the road as we had to wait for a ride because we had a dog with wife and I. Currently there is not a transmission recall listed for this vehicle. We were lucky to be in an area where we had cell phone service and relatively close to home, within 10 miles. We have a trip planned for next weekend to go to a couple national parks in Utah and now we don' t have a vehicle to take on this trip to haul out bikes.
While driving my Vehicle down Interstate 20 in Odessa TX the engine locked up and quit running at 70 mph in traffic. The truck is 13 months old with 17,000 miles on it. No warning lamps or alarms prior to the truck just shutting down. It was towed to the nearest GM Dealership and the Maintenance facility was able to diagnose that the motor was locked up. It was towed back to the purchase dealership in Shreveport LA at owner expense of $2,500.
While driving my 2022 Sierra elevation in April of 2023 my check engine light and a reduced power light came on and onstar diagnostics gave me a code of P30B2. Made a service appointment and was told there was an issue with the wiring. Problem was fix so i was told by the dealership, but the check engine light has come on 3 more times for the same reason.

Truck was placed in Park on an inclined road. Exiting truck, truck started to roll backwards. I was struck and right foot was run over by Driver's side front tire and knocked down. I was wearing composite toe shoes which enabled me to get up and run after the truck, trying to stop and control the truck a second time. I was hit again and thrown off the side of the road into a briar patch. Truck continued to roll backwards and off the road into the woods. Upon investigation, two separate County Deputy Sheriffs confirmed that the truck. when it came to rest, confirmed the truck was still in the Park position. Truck had to be towed out of a ditch in the woods. I sustained moderate injuries, but thankfully was not catastrophically disabled. This should be investigated thoroughly, so that no other person(s) is injured or dies as a result of this defect.
On 05/28/2022 my family was driving my brand new 2022 GMC Sierra 1500 3.0 Diesel at a rate of 60mph. There was suddenly a loud clunk (transmission) after proceeding a little further and getting speed back to 60mph there was a similar -??clunk-??-?? the diesel truck then immediately gained several various check engine / sensor lights all over the dash and went into Limp Mode. Speed slowly decreased from 60mph and finally as we were navigating our final left turn to our destination the truck would not accelerate thru an intersection subjecting our entire family to utter danger of oncoming vehicles. As a last ditch effort to save ourselves I put the truck in reverse and was able to reverse about 2mph. Then proceeded to shut the truck down and turn it back on to get out of the intersection, but the truck would not come out of park. Onstar emergency was contacted to call the police as we were in an extremely dangerous situation. This truck nearly caused our entire family to get in a very bad collision. The truck was stuck in the middle of the intersection for over 2 hours. The police even attempted to help getting the truck out of park, but was unsuccessful. The truck was scanned on site and had various codes including C1555 (x4) U0101 (x2) P25A2 U220F Collision assist light Check engine light Service Traction Control Light Service ESC The truck experienced catastrophic failure at only 319 miles. Day 4 of ownership. This vehicle needs to be investigated if it is failing this early on. There also needs to be a manual release for the parking gear. Truck has no way to be placed in neutral upon failure of the transmission relay.
