2022 GMC SIERRA 1500 Complaints

Tailgate inadvertently opens. There is no visual or audible alarm to inform me the rear tailgate is open. This is a Denali package truck. I have lost items, coolers, small folding tables among small items without warning. Most of the time I was traveling on a highway. Could cause accidents, injury to others as well as I have lost my belongings. I have had the dealership as well as 2 requests with GM customer service with no corrective results. The trucks tailgate will show an open display warning but only when top tailgate is down/open. If the whole tailgate is down/open there is no visual warning on dash. I believe there was an error in placement of open tailgate sensor when truck was produced. 2023 models have correct sensor placement and visual dash warning. The 2022 was a new redesign doe the Sierra class truck and there was a mistake where the open tailgate sensor was placed. I went to GMC virtual site and the 2023 model examined by GMC employee on visual check shows on complete tail gate down/open the same dash visual tail gate open alarm I see on my 2022 when only the top part of whole tailgate is open. My Dealership and GMC customer service have been involved for the past year. I have been reimbursed by GMC for my losses but problem still exists.

The car consumes oil to the point there's no oil in the engine. Not a result of a leak but rather the engine is actually burning it. I've taken it to 4 dealers, all confirmed it's due to Kia's bad engine design & that there's no visible leak anywhere. The kia dealer also confirmed there is no oil level sensor but only an oil pressure sensor. According to the dealer, I don't qualify for a new engine until the check engine light turns on or the vehicle results in a fire. I have to get the oil topped off every 500 miles. I don't feel safe driving this vehicle. The dealership also states I'm no longer covered under the warranty as I'm a 3rd owner. My coverage ends at 60,000. I was not aware of this during purchase of the vehicle back in 2020.

The contact owns a 2022 GMC Sierra 1500. The contact stated that while driving at an undisclosed speed, the service brakes monitor warning light illuminated. The vehicle was taken to the dealer where it was diagnosed with failed rear brake pads. The contact was informed that the rear brake pads needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 22,000.

While driving, on its own, the radio volume surged to 100%. All radio controls were unresponsive, and the volume was maxed-out.. Volume bar on the console display was reading 100%. Was unable to turn the radio down or off. Issue did not resolve until I drove home and turned the vehicle off.

While driving the vehicle, the volume on the audio panel shot up to 100%. It caught me off guard and nearly caused me to steer into oncoming traffic. All volume knobs and switches were unresponsive including the power button to the whole unit. I had to pull over and shut off the truck and let it sit for over 10 minutes in order to get it to stop. There are now numerous audio issues, including but not limited to the audio speakers making a crackling noise so bad it renders the use of any audio completely, also periodically the audio loses all volume and will remain completely silent regardless in AM/FM, Satellite Radio, bluetooth or phone call. All these seem to happen anytime the truck gets wet from either car wash or the weather.

Master break cylinder went bad and leaked fluid in side cab on driver floor board. Dealer identified that master break cylinder needed to be replaced.

The truck was parked indoors for a two days for tailgate repair/paint. The fire department responded to a fire at 6am 10/11/2023 and per their report the fire was started in the engine area of a 2022 GMC Sierra Denali. I am not the owner of the truck, my vehicle was damaged as a result. Owner's insurance has inspected the vehicle.

While driving the vehicle, the radio will suddenly and instantly jump to full volume frightening the driver and passengers and making it hard to focus on the road and control the vehicle. The dealership and GM will not fix the issue as it happens intermittently.

Unwanted Radio Volume Ramp Up to Max: The radio volume turned up to the maximum while driving and could not be turned down with user controls including those both on the steering wheel and the volume knob on the dash. The situation lasted about 60 seconds before it began responding again. The vehicle has the optional Bose radio system which is EXTREMELY loud. This issue presents risks with damage to my small daughter's ears, as well a significant distraction from driving due to frantic attempts to decrease the volume while being overwhelmed by the noise level.

I was driving the vehicle with my 4 year old daughter and experienced a complete brake failure. The dealership responded by replacing the master cylinder (the truck only has 16000 miles on it). Upon receiving the truck back from the dealer, another brake failure occurred. This is a dangerous vehicle and GM has done nothing to make it right with me.
