Hi, I was driving on [XXX] and my radio volume went to full volume 100% by itself. The radio would not shut off and none of the controls would work, everything froze. I kept turning the volume button down and the volume bar on the screen showed that it was trying to minimize, but it wouldn't stay. It kept going to full volume. Finally, after I kept pushing the off and mute buttons, the radio shut off and was unresponsive. When I reached my destination and shut the truck off and restarted it, the radio then worked as it normally should. This happened to me yesterday, and I'm still having trouble hearing and my ears hurt. I researched this online and found that there are many other people that had this same scenario with their sierra. I wanted to reach out and report this.

It is a known issue the OnStar modules fail and are on back order. They make you pay for 3 years of service on supply you a part that fails. This makes the phone app not work unbeknown to me when I had my kids and dog in the vehicle creating a safety is. This makes remote start and lock unoperable. This makes the GPS as well as the clock unoperable. This makes the sos call in emergency not operable.

When traveling on the interstate at 75 MPH the trim at the top of the grill broke free, hit the windshield and blew over the vehicle. The front of the grill you can visibly see where the metal clips fail and were completely sheered off. GM Authority has a bulletin published on 11/1/2024 citing other incidents of 2022 GMC Sierra AT4 owners who have had the same situation happen to them.

The tailgate will drop completely down by itself while driving at highway speeds. It has happened numerous times while driving on the interstate highway when I had large items in the back of the truck. Items such as propane cylinder, large cooler with ice and drinks, luggage, furniture, etc. The first time was a few days after buying the truck in Sep 2022. I reported it to the dealer, the ordered a replacement electrical component and replaced it. That did not correct the problem. I took it to another dealer in early 2024 and they worked on it but said it was going to be a recall by GMC but they did not know when. It's been almost a year and the tailgate still falls down by itself completely at random. It just happened again today while driving in heavy traffic on city streets. Fortunately, I didn't have anything in the back of the truck. It happened once during the night while the truck was in my garage and hit the garage door. I no longer put anything in the back of the truck, but I am concerned that it happens to others or will happen and someone on the highway will be seriously injured when a large heavy item falls out on the interstate highway. It can cause a major accident and GMC is obviously not as concerned as they should be. It's not the dealer's fault and is solely GMC's responsibility to correct this condition before someone is injured or killed.

Tailgate opens up in Park and/or when Truck is shut off. Tailgate continues to click after it opens itself. I have found my truck battery dead if left connected overnight. For the last week i disconnect the battery when i shut the truck off, and reconnect when i want to start it to insure getting to work on time. Same problem as what is described on the current Recall N242469160. But yet my truck is not show a recall on it.

UNKNOWN - While driving down the highway, the front hood molding flew off the front of my truck after a semi passed by me going the opposite direction. No physical contact was made to any part of my vehicle had occurred. The molding piece flew directly behind me on the highway and almost hit another car. I pulled over and inspected the front and noticed that the plastic clips that hold the molding piece in place had snapped off. After researching online, I have found numerous instances of people reporting the same thing happening to them.

Trim piece of chromed plastic on the front of the hood broke off and flew over the truck while traveling at 65mph. Fortunately no vehicles were close behind, but it could have damaged a following vehicle and/or caused them to swerve to avoid. This part is obviously a defective assembly. Photo available

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.

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.

The trim piece above the grill and below where the hood sits when closed failed/cracked at all attachment points (8 clips and 2 screws). This happened at highway speeds. The trim piece which is approximately 4-5 ft long and 3-4 in wide flew above the hood, struck the windshield and then flew behind the vehicle and may have struck another vehicle or motorcycle rider. This is a dangerous situation that could have injured or killed a motercycle rider if it had struck them. Apparently, based upon postings in forums and speaking with repair shops and the dealership this has happened a lot with this particular piece.

The volume of my stereo went to 100% max volume, the only way to turn it down was to continue to turn the dial as it continued to go up in volume. Once I was able to get out of traffic and pull over I turned off my vehicle and opened my door to turn it off but when I restarted it happened again. I tried restarting again and waiting longer between and it went back to normal volume control. This has happened twice since, my hands aren-??t on any controls when it happens.

- New London, MN, USA

The stereo turned all the way up and the sound buttons on the steering wheel plus the manual volume button were not responsive and it would not turn off. I turned the truck off and it still was on for 15 minutes. I turned it from Sirius XM to FM and then the volume worked but it hurt my ears and should never happen again.

The upper molding the the grille broke off while driving at high speed and likely caused issues for following cars. After researching the issue, this is a common problem with owners of this model. It is $1,500 to get replaced.

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.

- Enoch, UT, USA

Driving down the road and a large section of my grill came flying off the truck, hitting my windshield and the car being me. I pulled over as soon as it happened and the car that was hit kept going and did not stop. After a search on the internet it has brought up serval cases of this happening to other owners. This would of killed a motorcycle driver if he was behind me. We need action. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Have a 2022 GMC Sierra Limited with the 6.2L motor. About two months ago I started to have a shift to park message come up when turned off vehicle. The vehicle is in park as it sits on my downhill driveway and doesn't move. The computer is not sensing that the transmition is in park. I know that the areother models under the GM brand that are having this issue, "Shift to Park" as they call it. I would think this would be covered under the powertrain warrenty but dealership says no. I am not looking to drop $800 on repairs on the same issue they are having in other vehicles. There is a recall for the other models but not the 22 Sierra. Any information you could provide would be appreciated.

Tailgate open/clise module continues to open without me hitting the auto release device in the truck OR fob. NOTE: GMC built in Quebec! It resulted in a call to the dealership this spring, an inspection and they indicated it was fine. The tailgate opened while I was parking my new Airstream and it caused damage to the propane tanks and tanks cover AND $1700 damage to my tailgate.
