2022 GMC SIERRA 1500 Complaints

As I was driving down the road the front upper lip of my grill blew off and hit my windshield and then flew into car behind me. Looked online and this is a very common theme with GMC built in 2021 & 2022.

The contact owns a 2022 GMC Sierra. The contact stated that while the vehicle was parked, the tailgate independently opened. There were no warning lights illuminated. The contact called the local dealer to schedule an appointment however, the vehicle was not yet diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 20,500.

Grille trim piece came detached while driving on freeway damaging hood. Could have flown off and hit another vehicle. Took truck to dealership and it was replaced under warranty. Seems to be a known defect, lots of other people with same issue on Reddit.

The top part of the grill flew off while driving down the freeway and almost hit another car. Look at forums this is a very common issue and GMC needs to recall it.

On October 10 about 9am driving out of town on vacation for not reason at all my 2022 Sierra 1500 front upper lip of my grille broke off on freeway and we could not find it.

Driving down the road at 60 mph, the front upper grill piece just came off, flew up into the windshield and then over the cab of the truck and landed in the street. This is a known defect on these trucks and has happened in 100's of cases. When it happens it makes you react as if you had hit something with the truck, if there had been anyone behind me it could have also caused damage or made them react badly to something flying thru the air. When it happened to me I was prepared for it since I had read online of it happening to so many people. The cause is that its build with really flimsy, very thin tabs that just cant hold up to the wind speed and use needed for being mounted in the front of the vehicle.

Rear tailgate would randomly fall down without any key fob buttons being hit. Did some Google searches and it sounds like it is VERY common. There is a faulty tailgate switch that will randomly drop the tailgate which could cause damage if you have a bike rack on or things could fall out of the truck bed while driving if it isn't noticed that the tail gate has dropped

Front upper grill trim piece flew off truck causing a safety hazard for myself and others behind me. Flimsy tabs had broken and wind ripped the trim off.

The transmission failed without warning. The truck jerked several times and wouldn't go forward, eventually stopping, putting the driver at risk of being hit or losing control. There were no warning lights or issues prior to this. It was towed to the dealer who knew immediately that the transmission valve body had failed. He said this is a known problem and in fact there was a service bulletin issued last year by GM. As of now he told us there are 2000 vehicles waiting for this part. The part has been redesigned because GM knew it was faulty. Our truck is still at the dealer waiting for the part after a month. Others have been waiting for months. GM is not allocating the part for current customers but instead putting the majority in new vehicles even though they know there are thousands of vehicles less than 3 years old on the road and putting people in danger! The rest of us are left without a vehicle. You are welcome to inspect our truck at the dealership where it currently sits.

The upper trim piece of the grille broke off while driving down the road the other day. The piece flew up onto the window creating a distraction to myself and the vehicles behind me. The problem can not be reproduced by the dealership as its broken in pieces on the side of the road. Based on internet research this is a common occurrence. The vehicle has not been inspected by others There where no warning signs, messages or symptoms of the problem prior to the failure of the grille.
