2022 GMC SIERRA 1500 Complaints

While driving down the highway, then without any warning the front upper lip of truck grille flew off randomly. The broken piece shattered windshield and caused damage to body of vehicle. Reported to dealer, but they said I must have hit something to cause the damage. I did not hit anything. I was simply driving down the highway. This was a failure of the truck.

Upper molding of grille flew off while driving. Seems to be a common problem amongst 2022 Models of AT4

The contact owns a 2022 GMC Sierra 1500. The contact stated while driving 65 MPH, the radiator grille detached from the front on the vehicle. The vehicle was not taken to a dealer or independent mechanic to be inspected or repaired. The manufacturer was notified of the failure but offered no assistance. The approximate failure mileage was 50,000.

Upper trim piece of grill broke off while traveling down roar at 60mph. Part struck my windshield and flew over cab of vehicle and impacted the vehicle traveling behind me. Could've caused a much more serious accident!

While driving home from work, on the highway. Travelling 68 mph. The upper moulding on the front grille blew off, struck my windshield and landed on the highway behind me. Vehicles behind me had to swerve and slow as a result. I waited for a safe time to pull over and turn around to go back and retrieve the piece. Once retrieved, I could see the plastic clips had broken. Some are still missing. Wry dangerous situation, luckily it was not dark outside, otherwise I imagine other vehicles behind me may not have seen it, could have caused a bad accident.

Upper trim on front grille fly off while driving. All clips were broken, very thin plastic. This piece of trim nearly hit the vehicle behind me while driving 45-50mph. I've noticed there are many owners experiencing the same issue. The trim piece is separate from the grille but GM will only sell the full grille replacement. The upper piece needs to be redesigned for safety purposes and replaced on all similar models.

The coolant control valve failed, and there is a recall for a software update for a valve issue in the transmission. The DEF system is flawed with the level being shown by approximate using a computer to calculate versus a level sensor or sending unit. My NOX sensor was replaced and the check engine light came back on for the same reason. It ended up being corrected by filling up the DEF.

Infotainment system volume shot up full blast on its own with no operator control or influence. The volume of music was so high that it was hard to concentrate on driving while trying to reduce the volume and could not. Had to pull over on the side of the road and shut off vehicle to get the volume to go down. This could be a potential safety risk when driving at higher speeds causing the driver to not concentrate on the road and other surrounding vehicles. I reported issue to dealership and have not had it looked at yet as it has only happened one time. The volume indicator flashed on the screen and showed the volume indicator bar going up to full blast. No other indicators or warning were present at the time.

The tailgate is randomly opening during driving. I had some equipment fall out on a busy four lane road, I only knew because I had my window down and heard some clanging. I looked out my rear mirror to see tools going all over the road. I had to go back and close a lane with the truck and clean up everything in traffic before a crash was caused. It happened recently again, but luckily, my camper shell kept the gate up this time even though it was unlatched. I thought maybe the key fob, which has a button to open the tailgate, was being pressed. However, I just tested it in the parking lot, and the key fob does not work when moving (as it shouldn’t). No codes are being shown on the dashboard. The tailgate is actuated electronically by the computer, and there is no mechanical link or handle to open it.

As I was driving down the highway, the top piece of the grill flew off, went airborne, and almost struck the vehicle behind me. When I got home, I looked to see what caused this to happen. The piece was secured by flimsy plastic clips which had broken off. This is a complete manufacturing defect which is on GMC Sierra 1500s years 2022 to present and needs to be recalled. It's happening to a huge number of people based on the reports on Facebook groups.
