GMC Complaints

My 2022 GMC Sierra 1500 shows message "Shift To Park" when turning off, even though it has been shifted to park. Have to play with shifter to get it to stop, sometimes turning it back on and off will do trick. Locking it with remote works most of the time but this last time it took over 10 minutes .

Gear slipping since I’ve had the truck. Replaced parts of motor, new transmission installed and still gear slipping entering the second gear. A big jolt happens every time I accelerate and when I slow down about the 10 mph mark it jolts again. Spent well over $10,000 on major truck repairs. I just don’t understand how this truck has 0 recalls. My truck is similar to all of the v8 Sierras of that year and I strongly feel it should have been recalled due to the gears slipping and not enough power.

ENGINE WORK VALVE INTAKE LIFTER AND CAMSHAFT REPAIRS / OIL SENSOR HAS BEEN GOING HAYWIRE / REAR STRUTS KEEP POPPING OFF AND AFTER STRUTS REPAIRED BOUGHT THE TRUCK 05/2024 AND HAD TO TAKE TO REPAIR 12/2024 AND ONCE MONTH EVER SINCE.

During an oil change I noticed unusual wear on the front passenger side tire. Upon investigation my mechanic found that the chassis was cracked which pushed the tire causing it to rub. Very concerned this could have caused a very bad accident.

When backing up and nothing behind car abruptly applies brakes no alerts. This has occurred on multiple occasions and is very scary. This started first week of ownership took to the dealer and was told GM is aware of the issue but no repair available at the time. the car is a year old now and problem is still present I have had to disable the braking feature. The backing emergency braking is a safety feature so pedestrians / children don’t get run over.

When I put my vehicle in park, the message “shift to park” pops up. It has been doing this for well over a year. I have already had to replace a battery once due to this because I didn’t realize it was still on. It does not happen everytime I park but at random times. The more it happens, the longer it takes for it to go off. At this point, I can only hope my car is really in park. I jiggle the shifter, hit the “ +|- “ on the shifter and have to turn the vehicle off and on about five or six times. Eventually it will go off. It took me 20 minutes today for it to go off in 100 degree heat. The vehicle’s AC is not running when trying to get the shifter to go off. It keeps the electronics running but not the AC. I keep waiting to receive a recall on this vehicle because of this issue but still nothing. I have noticed there is a recall for this but not vehicle. I have already replaced one battery due to this issue and do not want to continue to replace batteries and worry if the vehicle is really in park or not.
