STEERING, SERVICE BRAKES, POWER TRAIN
Truck showed check engine light and popup message to Service ESC, vehicle disable traction control. Before being able to have the vehicle scanned for error codes (after sitting parked turned off for a while, all errors cleared. Several days later when turning vehicle on traction control warning light, parking break warning light, and stability control warning light all turned on, service ESC message popped up again, PRNDL position indicator light turned off and vehicle began to have a clicking noise in the steering column when break was pressed. There is a multiple year long thread on this topic on the silveradosierra forum entitled "service-esc-and-service-power-steering" it appears that dealer and GM help are limited and the issue often goes away and recurs.

POWER TRAIN
The automatic transmission occasionally slips and slams hard into gear between first and second gears, causing the truck to lunge forward when attempting to stop. This could potentially cause the truck to hit another person or vehicle when attempting to stop. This problem was immediately observed upon receiving the new truck in 2017 and is ocurring more frequently over time. The problem was reported to and taken in to the GMC dealer. They advised that they were unable to reproduce the problem during their time with the truck. There have been no safety incidents thus far. No warning lamps or messages have been displayed on the dashboard.

The upper front grill molding flew off the vehicle while moving and the parts are available for inspection. Please see uploaded photos. The safety of motorcyclist and other vehicles following me were put at risk of being hit by a 24 inch wide piece of the upper front grill at high speed that flew off the vehicle while traveling on the highway without warning. The problem has been confirmed and reported by numerous vehicle owners like mine posted in online forms that I have attached to the upload files section of this correspondence. The vehicle was inspected for repairs by the manufactures dealership representative and a repair invoice has been uploaded. There were no warnings prior to the failure of the upper grill molding being dislodged from the front grill while the vehicle was moving.

The most recent time, I was almost rear ended because of this issue.

POWER TRAIN
While driving 55mph on a 2 lane road, pulling a 5th wheel camper, the truck transmission downshifted by itself to a low gear. This caused a scary and immediate deceleration from 55 to 25mph. The trailer wanted to push into the oncoming lane the deceleration was so fast. The truck is at a dealership and they acknowledge the issue but not a fix other than putting back in the failed part. There was no warning and my readings say many others are having same issue. The small dealership we left the truck with (yemm Chevrolet in Galesburg Il) said they had 3 trucks with the same issue. The truck has been with the dealership for 7 weeks now.

STRUCTURE:BODY
While driving in the highway at 60 mph, the top of the front grille flew off, hit the hood, and impacted the windshield before flying off to the passenger side of the vehicle. It impacted multiple locations on the passenger side of the vehicle as it flew off. Nothing hit the grille at the time it flew off. We were driving on a busy highway. Thankfully, the cars behind us were at a safe distance. If there were a motorcycle or another vehicle, it could have seriously injured someone or caused them to swerve their vehicle. Researching this online, multiple owners of the same vehicle have experienced the same issue. Many experiencing it when traveling at highway speeds. It seems like the thin plastic tabs that attach the top grille piece to the front of the vehicle are not strong enough to hold it. No damage had been done to the grille prior to the incident. I always use a touchless car wash, so it wasn’t loosened by that. I haven't contacted insurance or filed a police report. I'm hopeful the damage will be covered under the manufacturer warrant.

STRUCTURE:BODY
I was driving down the interstate when the top trim panel of my grille flew off my truck. The piece flew into the traffic behind me, and fortunately, no one was injured. If there was a motorcycle behind me, the rider could have been severely injured or killed. The piece that flew off is located just above the grille and below the front edge of the hood. Multiple people have reported the same issue with their trucks. This morning, the parts department at my dealership confirmed that I was not the only customer to present this problem. There is nothing to warn of the problem before this piece flies into traffic.

UNKNOWN OR OTHER
Have a 2022 GMC Sierra Limited with the 6.2L motor. About two months ago I started to have a shift to park message come up when turned off vehicle. The vehicle is in park as it sits on my downhill driveway and doesn't move. The computer is not sensing that the transmition is in park. I know that the areother models under the GM brand that are having this issue, "Shift to Park" as they call it. I would think this would be covered under the powertrain warrenty but dealership says no. I am not looking to drop $800 on repairs on the same issue they are having in other vehicles. There is a recall for the other models but not the 22 Sierra. Any information you could provide would be appreciated.

STRUCTURE:BODY
A large part of the grill on the front of my truck but broke off on it's own while I was driving. The part is called the Upper Grill Molding Part number 20863. It's about the size of a ski (5.5 ft long and 6 inches wide). It flew off and almost hit the car traveling behind me. They had to swerve off the road to avoid hitting it and almost got into an accident. After inspecting the part and how it is supposed to attach to the grill, it is apparent that is was very cheapy installed with flimsy plastic mounts and minimal glue. My truck only had 19,000 miles on it when this happened. I took it to the GMC dealer and they said the entire grill would have to be replaced because they don't sell that part separately. I researched this issue online and found thousands of other cases with the same scenario happening. This manufacturer's defect should be recalled as it poses a severe safety risk to pedestrians and other vehicles.
