I purchased my Sierra in 2021 and 2 weeks after purchase I got a warning for service stabilitrk and another for trailer brake system. This is very very annoying and also has my abs light on. My next issue is a code u510 for active grille shutter assembly. Please fix these issues as they are very common and unsafe. Not to mention as much ad I paid for this truck.
AC condenser went out on my vehicle with 100,000 miles, lots of reviews online stating this is a known problem but yet there is no recall. Torch Converter going out at 80,000 miles.
Like many of the 2014 and 2015 models, my vehicle has experienced the exact same failure in the radiator due to the thermostat over cycling. There is already a TSB for those models, yet GM changed nothing in the subsequent models and the problem persists.

Received an error on the dash saying "Service Brake Assist". At the same time the brake pedal became very stiff and braking power was decreased significantly. I have received this same message and brake pedal stiffness with reduced braking power three times in the last 4 days.
My rear back heated window on the passenger side popped and shattered the window while I was sitting in the passenger-??s seat waiting for my husband. The truck smelled like a sweet wire smell and then I heard a loud pop. I looked back and the back window panel was shattered. I do see that there were recalls on some of these windows.
After cold starts when accelerating the transmission slips from 1st to 2nd and throws your body forward. After that first gear change it doesn't do it again until another cold start. Around 34000 miles I am getting a rumbling vibration through the dash and steering wheel when holding speed between 35-75 mph. The RPM guage will jump slightly and it will feel like going over rumble strips. Acceleration is very weak at times. Sometimes its ok. There has to be something done with these torque converters and transmissions by GM. Unacceptable for a 40-50K dollar truck!
Condenser on ac leaking at same location as the 2014-2017 my. Warranty was out due to mileage but truck is only 2 years 3 months old. Blowing warm air when ac was turned on.
A/C stops working 2.) mechanic does vacuum test and replaces refrigerant ($200) freon 3.) A/C is blowing hot air again after 3 days; refrigerant completely gone 4.) mechanic runs dye through lines to find the leak, replaces refrigerant again and states the problem is compressor failure ($200) again 5.) the overall fix would be to replace the compressor ($1,000) but there are no compressors to be found, the part is on national backorder because of the widespread problem." Left side of wheel making aloud noise when backup, it is a know problem with the steering rack tansmission downshift from 30-15 make a push effect and couching noise
The Sierra surges from park to reverse and drive. I bumped a vehicle today, and the surge has become an issue this week and there is not even 9,000 miles on the truck. The afm is rough shifting between V8 and V4 mode too. None of this was an issue until recently. My speakers also vibrate like a blown speaker on high definition radio, but not on regular radio stations.
My vehicle is hacked anytime I am driving the vehicle I am not in full control. The vehicle steers itself left or right while driving, the brakes are always on while driving sometimes braking harder but always on. The infotainment system has many glitches. This vehicle has been back to the dealership more than 15 times has been out of service over 35 days GM even flew a engineer/tech to inspect the vehicle and says they couldnt find anything. Therefore this vehicle is hacked there are so many issues and glitches and the fact that the truck only acts like this when I am driving no one else. Like it can be turned on and off instantly. I have tons of videos pictures and supporting documents backing this. I need help this is a serious issue and there is so much more to it than I can type here someone please get ahold of me to help or point me in the right direction. This vehicle will be returned to GM soon as they are doing a vehicle replacment per all the issues but this needs further attention because if this can happen to me it can happen to anyone. Please help
The vehicle operates unpredictably when pressing on the gas pedal causing unsafe driving conditions. When pressing the gas pedal, any one of the follo^wing conditions may occur. 1.) sometimes the RPM's decreasea. 2. )sometimes the transmission hunts several times. 3.) sometimes the vehicle speed surges. 4.) many times the engine hesitates for a long period before the RPM's increase. This unpredictable operation is more apparent when the engine is loaded like going up hills and especially when heading into strong winds. The unpredictable operation is extremely unsafe when driving on ice covered roads. This vehicle is also considered an "off-road" series vehicle. This unpredictable operation is very unsafe, even dangerous, on aggressive trails. When driving in steep trails, drivers require feedback from their vehicle especially how the vehicle or engine responds as the gas pedal us depressed.
