2022 GMC SIERRA 1500 Complaints

The contact owns a 2022 GMC Sierra 1500. The contact stated that while driving at an undisclosed speed, he heard a knock sound coming from the engine compartment. No warning lights were illuminated. The vehicle was taken to the dealer, and during an inspection, the engine seized, after which the dealer diagnosed a failure with the rod bearings. The vehicle was repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 31,000.

The engine failed while driving on the expressway. It is clearly the fault of the Active Fuel Management (AFM) system but GMC will not honor the warranty because I went over 7,500 miles between oil changes. This is a problem because the car stopped operating while driving down the interstate. Manufacturer inspection took place. They looked at the oil filter and saw the metal in the oil filter. No warning lamps, messages or symptoms of any sort prior to the engine failure.

The transmission became inoperable and a message appeared on the display 'Engine Power Is Reduced' in area of the highway where the speed limit is 55 and then the transmission failed completely and left the engine revving at high rpm and not moving the vehicle forward and we rolled to the side of the road to a stop. This was a very dangerous situation as traffic was flying past us and had to move out of the way of our coasting vehicle. It was towed to a GMC dealership about 8 miles away as it is still under warranty. I've read many stories in GM forums about problems with this GM 10 speed transmission in this pickup truck. This needs to be looked into as a potential recall as this problem left us stranded on the side of the road as we had to wait for a ride because we had a dog with wife and I. Currently there is not a transmission recall listed for this vehicle. We were lucky to be in an area where we had cell phone service and relatively close to home, within 10 miles. We have a trip planned for next weekend to go to a couple national parks in Utah and now we don' t have a vehicle to take on this trip to haul out bikes.

Rear tailgate randomly opens on its own while driving. Items from the rear bed can fall out causing a traffic hazard

Multifunction tail gate opens while driving, opens when going over speed bumps, opens going over small bumps and opens while driving down the highway. I brought the vehicle to the GMC dealer, they replaced an electrical switch on the tail gate. This did not fix the problem, I called the dealer and they told me GMC does not have a repair for this new issue. This is a brand new truck that is under factory warrant, the truck has 10000 miles on it. If I ever have a load in the bed it may fall out onto the road or highway.

I am reaching out to you to make a report of a safety issue involving the 2022 GMC Sierra 1500 Denali model trucks (Vin [XXX] ). I recently read that there was a recall involving the 2020-2023 model 2500 GMC Sierra’s and their Multi-Latch tailgate. I have checked with GMC and my local dealer to see when or if my model would be included in this recall and they have no answer/response for me. The reason for my concern is that I had an issue last year with my tailgate dropping while in motion while pulling my camper. The result was that my tailgate was destroyed and damages were made to my camper as well with both needing to be repaired. The only reason that the bikes, propane tanks, etc that was in the back of my truck didn’t fall out and into moving traffic was because my camper was hooked up thankfully. Its very concerning to know that this same thing can happen again in the future at any given moment with the lack of a recall on my specific model truck. If the things I were hauling would have flown out the back at 60-70 mph it could have ended a lot worse for someone who was following behind me on the road. Additionally, the damages had to go on my driving record as an “at fault” accident which in turn caused a rise in my personal insurance rates. My insurance company assured me that the only way this can be removed was if an active recall were to be addressed with my model truck for the tailgate issue.

The radio volume went up to max an it's own twice, both times it almost caused a crash. Nothing would make to volume turn down, not the radio volume dial or the buttons on the steering wheel. I had to pull over, stop and turn off the truck.

The contact owns a 2022 GMC Sierra 1500. The contact stated that while driving and transporting a trailer at an undisclosed speed, the tailgate was independently activated. The contact was alerted by a nearby driver that the tailgate was open. The contact stated that due to the failure, the tailgate was damaged. In addition, the contact stated that the failure had occurred previously several times. The vehicle was taken to the dealer. However, the contact was advised to report the failure to NHTSA. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 12,000.

Driving at 50mph on straight road. No traffic in front. Truck brakes activated. Went down to 29mph. Then picked up speed on its own.

On January 20th 2024 I was cleaning heavy dirt and mud off of my truck, after leaving the car wash and driving about 20 miles, once I parked my tailgate started to open over and over on its own. This happened again on March 4th 2024 after cleaning off a lot of dirt from my vehicle the tailgate opened on its own while my truck was parked in the garage. It opened into the garage door, when I left I did not know it was open, so when I opened the garage door the hinges on the garage door scraped and dented the tailgate as it opened. I had not pressed any buttons inside the truck, outside of the truck, or pressed the tailgate open buttons on the key fob. After intense car washes it has opened on its own each time.
