2022 GMC SIERRA 1500 Complaints

I was driving on the interstate when the hood deflector blew off suddenly and unexpectedly damaging my hood and hitting the windshield. This vehicle was recalled for this part defect last year and the fix was applied by the dealer. It appears that some sort of adhesive was applied to the retainers but they still ultimately failed. This was a very dangerous situation that could have ultimately caused an accident. I am reporting this so that the approved repair can be reviewed. This part should have been replaced, not simply placing adhesive on the defective part. The past safety recall # was N242490120.

The front chrome grille deflector came off 9-10 months after the dealership inspected it.

Driving down the road, the radio volume will randomly rapidly increase to full volume. There is no way to turn the volume down. This is very startlingly and can lead to an accident due to the driver panicking and trying to turn off the radio or turn the volume down. It has happened approximately 5 times since I have owned the vehicle. Thie first time was when the vehicle was only a few months old. It happens so infrequently that it cannot be reproduced. It has not been confirmed nor inspected by a dealer. There is no warning as to when it might happen, nor any similar circumstances when it happens. The only solution I have found is to stop, turn off the vehicle and open the door for a minute or two, which is difficult to do in traffic.

My telematics onstar unit went bad at 37,200 miles. No onstar, no SOS, no hands free driving, etc. I paid roughly 3k for the extended subscription servies for three years. Like many others who have this problem, dealer/GM will not replace the faulty unit even though I still had time left on my on my subscription. Apparantly its a common problem.

Setting in a parking lot and the tailgate fell open and hit another car. The tailgate was closed and has fell open 3 more times while the vehicle is in park and one time it was powered off.

Complete engine failure, at 57,000 miles, was driving approximately 75 mph on the I-15 in Utah outside of St. George, and the left lane, engine turned off, was able to pull safely in a shoulder in a canyon with my family, my wife, my kids [XXX] and [XXX] old. Vehicle was towed that evening at 7 PM to the dealership, where it was diagnosed with completed engine failure.

2022 GMC AT4 w/ 6.2L V8 was my retirement gift to myself at a cost of $70k. I have had 2(two) engine failures! Of course they failed in the middle of rush hour traffic when no one wants to be kind. Since the wheels will NOT rotate once the failure has occurred, I was stuck in middle of traffic for 2 hours awaiting a tow truck. Not even 3k miles after the 2nd engine failure I was told by the dealership that I now need a transmission replacement. As a loyal GM customer, GM has to do better.

Just after merging from I-65 North to 264 East at 65 mph in Louisville KY on November 14th, the display indicated to "press start" and the engine stalled. I was only able to get the vehicle about 3 inches off of the left side of the yellow line before running out of inertia. I was stuck there for 2 hours while waiting for a tow truck. The first truck could not lift my vehicle because with the engine off, the electric shifter would not move out of park. A second tow truck was called with dolly's and then a 3rd tow truck was required to block traffic. During this 2 hour period several cars swerved left of the yellow line and I was in fear for my life. The traffic was so heavy that I was trapped between the concrete median wall and the left lane. I called 911 to ask for a safety vehicle to shield me from traffic, but they never arrived as promised.

The contact owns a 2022 GMC Sierra 1500. The vehicle was repaired under NHTSA Campaign Number: 25V060000 (Structure), but the failure occurred. The contact stated that while driving at 65 MPH, the top deflector shield detached from the vehicle. No warning lights were illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 13,100.

I had a lifter fail which is a well known problem for these GM engines. The lifter caused the cam shaft to be damaged because of the lobes being shaved off. Now I’m being told that it will be over $10,000 fix a 3 year old truck.
