2022 GMC Sierra 1500 complaints

My 2022 Sierra Denali shows message "Shift To Park" when turning off, even though it has been shifted to park, the dashboard stays lit as well as the radio on. Horn even goes off alerting as if the engine is on and me walking away with the key in my pocket even though engine is off. Have to play with shifter to get it to stop, sometimes turning it back on and off will do trick. Locking it with remote works most of the time but when this happens, I can't use remoteless key access, door just won't lock.

The contact owns a 2022 GMC Sierra 1500. The contact stated while her husband was driving 40-45 MPH, the vehicle experienced reduced engine power and failed to exceed 30 MPH. The driver was able to pull to the side of the road. The driver turned off and restarted the vehicle. The contact stated that upon shifting to reverse(R), the RPM decreased, and the vehicle failed to respond. The driver was able to drive to the dealer, where it was diagnosed that the transmission had failed, and there were metal shavings inside the transmission. The dealer determined that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that the VIN was not included in a related recall. The manufacturer referred the contact to the NHTSA Hotline for the VIN to be added to a recall. The failure mileage was approximately 90,000.

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.

Driving on the highway, the upper grill molding on the leading edge of the hood broke off and came up and hit the windshield and top of the cab. Upon further research online, this seems to be a pretty common occurrence on sierras with the at4 trim package. I was told by the dealership that extended warranty does not cover this and I would have to order an entire new grille, over $1000

When the truck reaches approximately 50mph it is unable to shift into the next gears and then it's unable to downshift. The transmission will not go into neutral. The truck must be stopped and turned off, sometimes it will need to be restarted 2x before it's able to shift into first gear. The outdoors temperature was approximately 24F, transmission temp was 178F. The truck locked into 7th gear 6x in a row while the transmission was set to normal driving mode. There were no signs of transmission failure until the vehicle reached approximately 50mph, afterwards the check engine light illuminated, a warning stating "reduced acceleration drive with care" and "service transmission now unable to shift soon". The trucks RPMs were approximately 2500rpm while driving 45mph and would not go down because the transmission would not shift up or down.

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

As I was traveling down the interstate at about 70 mph the front upper grille moulding flew off and almost hit the vehicle behind me. The clips that held this on the vehicle are very weak and this is happening to many of the same vehicles. Had I hit a car behind me there could have been significant damage, and luckily there was not a motorcyclist behind me. I did not hear any rattling or have any damage to the vehicle, this is simply a manufacturer's issue.

While driving approximately 70mph down the freeway the upper grille assembly snapped off and went airborne, it struck the passenger side of my windshield putting 2 large scratches on my windshield. It then hit the roof of the vehicle and continued over my vehicle. Upon inspection the guard is held on by extremely thin clips and all clips sheared in almost identical spots. This creates a huge safety hazard for motorists behind the Vehicle that could be struck by the flying piece.

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!

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.

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.

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.

Top Grill piece attached to hood blew off in the wind.

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.

Upper grille trim piece flew off.

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 contact owns a 2022 GMC Sierra 1500. The contact stated that her son had called while pulled over to inform her that the vehicle was driving rough with the check engine and several other unknown warning lights illuminated. The vehicle was taken to the dealer to be diagnosed. The contact was informed that the engine had failed and needed to be replaced. The contact stated that the dealer had since closed, and the vehicle was then towed to Marty's GMC (5 Kingston Collection Way, Kingston, MA 02364); who confirmed that the engine needed to be replaced. The vehicle had not yet been repaired. The manufacturer was informed of the failure and opened a case. The failure mileage was 78,000.

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 contact owns a 2022 GMC Sierra 1500. The contact stated that while driving at various speeds, the vehicle suddenly shifted into a higher or a lower gear, the contact stated that when this occurs the vehicle will aggressively jerk into either the higher or lower gear, and the vehicle experiences reduced acceleration to approximately 30 MPH. The check engine warning light was illuminated. The vehicle was taken to a local dealer where the vehicle was diagnosed. The contact was informed that there was a leak in a backflow valve that was responsible for the failure experienced. The contact stated that the failure had occurred five times was provided different causes for the failure, even though the contact stated that the failure was the same failure. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 30,000.

I was driving on the highway at approximately 65mph and the upper top moulding suddenly broke off, flew across my truck hitting my windshield, before landing in traffic. I had not had any previous damage to my truck prior to this incident. I am concerned this is a widespread issue that is creating an undue burden on the owners and potentially create unsafe conditions to nearby vehicles/pedestrians. I took my truck to the dealership as I have a warranty, but they refused to cover the cost of replacement.

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.

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.

I was driving down the highway at approximately 60 mph, and the upper front trim from above the grill flew off, struck, and cracked my windshield. Based on my research, this is a very common problem and a serious safety concern for drivers of 2022-2024 GMC Sierras. It is also a safety issue to the general public for anyone traveling or walking near this vehicle when this condition occurs. There was also an article published on gmauthority website about this common issue as well as multiple Reddit posts and GM Forums.

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.

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.

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.

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.

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.

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

Upper bumper flew off driving on the highway

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.

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)

The upper front grill molding flew off the vehicle while moving and the parts are available for inspection. Please see uploaded photos. The safety of motorcyclist and other vehicles following me were put at risk of being hit by a 24 inch wide piece of the upper front grill at high speed that flew off the vehicle while traveling on the highway without warning. The problem has been confirmed and reported by numerous vehicle owners like mine posted in online forms that I have attached to the upload files section of this correspondence. The vehicle was inspected for repairs by the manufactures dealership representative and a repair invoice has been uploaded. There were no warnings prior to the failure of the upper grill molding being dislodged from the front grill while the vehicle was moving.

While driving in the highway at 60 mph, the top of the front grille flew off, hit the hood, and impacted the windshield before flying off to the passenger side of the vehicle. It impacted multiple locations on the passenger side of the vehicle as it flew off. Nothing hit the grille at the time it flew off. We were driving on a busy highway. Thankfully, the cars behind us were at a safe distance. If there were a motorcycle or another vehicle, it could have seriously injured someone or caused them to swerve their vehicle. Researching this online, multiple owners of the same vehicle have experienced the same issue. Many experiencing it when traveling at highway speeds. It seems like the thin plastic tabs that attach the top grille piece to the front of the vehicle are not strong enough to hold it. No damage had been done to the grille prior to the incident. I always use a touchless car wash, so it wasn’t loosened by that. I haven't contacted insurance or filed a police report. I'm hopeful the damage will be covered under the manufacturer warrant.

I was driving down the interstate when the top trim panel of my grille flew off my truck. The piece flew into the traffic behind me, and fortunately, no one was injured. If there was a motorcycle behind me, the rider could have been severely injured or killed. The piece that flew off is located just above the grille and below the front edge of the hood. Multiple people have reported the same issue with their trucks. This morning, the parts department at my dealership confirmed that I was not the only customer to present this problem. There is nothing to warn of the problem before this piece flies into traffic.

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.

A large part of the grill on the front of my truck but broke off on it's own while I was driving. The part is called the Upper Grill Molding Part number 20863. It's about the size of a ski (5.5 ft long and 6 inches wide). It flew off and almost hit the car traveling behind me. They had to swerve off the road to avoid hitting it and almost got into an accident. After inspecting the part and how it is supposed to attach to the grill, it is apparent that is was very cheapy installed with flimsy plastic mounts and minimal glue. My truck only had 19,000 miles on it when this happened. I took it to the GMC dealer and they said the entire grill would have to be replaced because they don't sell that part separately. I researched this issue online and found thousands of other cases with the same scenario happening. This manufacturer's defect should be recalled as it poses a severe safety risk to pedestrians and other vehicles.

A large trim piece at the top of my grill flew off while driving 70+ on the highway. I have personally seen roughly 100 testimonies with picture proof on various fb pages of others with the same vehicle experiencing the same thing. This is a known issue for the 2022-2023 model years, GM has apparently corrected the issue for the 24+ model years.

In the past 6 years I have owned 4 GMC 6.2L trucks the first was a 2019 no issues great truck. The second unfortunately had a Short life with another vehicle. In 2023 The third a 2021 Denali 6.2L truck at 34k began using oil and blowing blue smoke out the tailpipes. The dealer started an oil consumption test (like you couldn’t see it happening) so finally at 45k they tore down the engine and found worn out valve guides and scored cylinders. They ordered an engine the engine was installed and it failed in 25 miles come to find out it was not oiling on one bank, A second motor was ordered and installed it failed at start up. At this time it had been months that the truck was down. The dealer took a stand and moved me into a 2022 GMC AT4 with 6.2L with the hopes of removing the issue this truck was the internet sales managers truck that he had recently bought and had 15k on. We made the deal, well at 35k this truck begins consuming oil. The dealer once again starts the oil consumption test process. A couple of months ago. The truck now has 42k or so on it and on my last trip from Atlanta to Fort Walton after the dealer just topped it off 2 1/2 weeks prior to the first 2500 interval of the oil consumption test, the truck burned 1 1/2quarts in less than 2k miles and the oil warning light comes on as we arrive in Fort Walton. I would like a resolution to this, I have invested a lot of money into what should be one of the most reliable trucks on the road and all I hear is GM says it
