general problems of the 2022 GMC Sierra 1500 - part 1

Coolant control valve failed, truck cannot be driven due to overheating, dealer has said due the national backorder, it could be 2 months before they receive the replacement part. There is a significant national backorder on the engine coolant flow control valve for 2020–2025 GMC sierra and Chevrolet silverado trucks equipped with the 3. 0l duramax (lm2/lz0) diesel engine. Many owners are reporting wait times of several weeks to months, with some vehicles sitting in repair shops for over 70 days.

Onstar module is not working.

Driving down the road, the radio volume will randomly rapidly increase to full volume. There is no way to turn the volume down. This is very startlingly and can lead to an accident due to the driver panicking and trying to turn off the radio or turn the volume down. It has happened approximately 5 times since I have owned the vehicle. Thie first time was when the vehicle was only a few months old. It happens so infrequently that it cannot be reproduced. It has not been confirmed nor inspected by a dealer. There is no warning as to when it might happen, nor any similar circumstances when it happens. The only solution I have found is to stop, turn off the vehicle and open the door for a minute or two, which is difficult to do in traffic.

The front chrome grille deflector came off 9-10 months after the dealership inspected it.

Tailgate opened on its own while driving, creating a safety hazard where items inside could have fallen out. The tailgate was secured prior to driving.

The onstar system completely shut down. The module stopped working while driving and now there is no communication to the vehicle.

Trailer brake control is junk, it is a known problem! while driving the control shut of the brakes of the trailer. Had a fully loaded trailer 14,000 pounds with no trailer brakes, ended up going through red light, because the trucks brakes where not enough to stop trailer!.

Recently, I just purchased my vehicle from wally edgar chervolet with no open recalls on the vehicle. As of September 29th, 2025 for my very first oil change on the vehicle I was made aware for 4 open recalls which was told to me at the time of purchase. The dealership closed the all recalls without actually checking my make the vehicle was safe to drive. The recall numbers are: n252510321, n222362040, n212356230, n222357620.

I received a new engine. Went in 8/15 - 9/10. Truck was dead on 9/22 when state farm sent out a guy to replace the windshield that came back broken from the dealership. I had put in a new battery on 4/17, before I even knew about the recall. I got the battery out and replaced under warranty from autozone. Before we connected the 2nd new battery, my friend checked the oil. . . Just for fun. There's barely any oil on the dipstick. Service guy told me I'm checking the oil wrong, that it needs to be running for a while, so that's why it's reading low. Okay!!!! lol. 7 days later, truck was dead again. Last week, 10/21, I'm told by gm customer support to not have it towed in yet until I hear back from a senior advisor, after telling her my long winded story. She said it would be within 48 hours. 72 hours passed and nothing. Supposedly I'm receiving a call at 12:51pm today, yes that's correct, that's literally what they told me when I called in yesterday. I'm having the truck towed in today, 10/29. I continue to be jerked around, ignored, lied to from all angles of gm. My truck has been inoperable and/or unsafe to drive for over 6 months now, costing me all of my income from my 2 jobs that require my truck. Gm needs to be held accountable.

The front chrome grill indicated in the recall came off while my wife and I were driving at 70 miles per hour. A big rig was passing in the on coming lane at the time. The part came off striking our front windshield almost causing a wreck and causes emotional trauma. It was a very scary experience. Our local dealer supposedly ordered the part two months or more ago from gm. They told us two days after the failure the part was still not available. I called gm who stayed the part was shipped well over a month and a half ago. Someone isn’t telling the truth. This incident should never have happened to us since it was a known safety recall. It should have been replaced.

I was sitting outside , and then all of a sudden my tailgate on my truck opened upped. And I heard there’s a recall on the latch but apparently it’s not on my truck when I looked it up on google. It does say some 1500s have the problem. I am very worried that it’s gonna open up in a parking lot on a car or a concrete bumper. Can you please look into this? my truck is going in for service next month and I would like to get it fixed with no charge of course because of the recall. Please call me if you have any questions.

Vehicle showed me error code “ brake failure dont drive over 43mph “ and some other error codes I took the vehicle to the dealer because it was serious they made me sign a diagnostic fee document that I will be responsible for the diagnostic but the issue was just battery needed to be replaced according to the dealer we did the repair at the dealer battery + hours + diagnostic but the misleading error codes made me take the car to dealer what was unnecessary so please look into it customer are getting charged for unnecessary repairs because of misleading error.

My 2022 GMC Sierra 1500 shows message "shift to park" when turning off, even though it has been shifted to park. 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 this last time it took over 10 minutes .

The radiator needs to be replaced on the 3. 0l due to a leak in the seam of the radiator. The dealer has stated that they have had a few in the shop recently due to the same issue. There are a lot of complaints online that have the same issue, and customers have had to pay $3000 for the same replacement.

The onstar module is no longer working. When I purchased the vehicle, the green light did not turn on. I called customer service, and they advised me to take it to the dealership since they were unable to connect to the vehicle. I am unable to contact emergency services in case of an accident, and I cannot access services like remote location and remote start from the mygmc app. I have seen several people online state that their module failed as well. It's a common occurrence that falls onto the customer to pay for. An update to the module seems to be the reason so many modules are failing.

The tailgate keeps dropping while driving and while parked. The key fob is in a protected area or not near truck at all when this occurs.

This truck is burning oil faster than it takes us to do an oil change we have to check it once a week to make sure it had oil in it. I have seen online I am not the only one having this issue this year make and model. I want to report this problem.

I am unsure except for what they told me the engine completely seized up I was heading back from grand junction colorado over vail pass nothing appeared wrong with the engine it was going fine and then completely powered itself down and stopped at the top of the pass would not come back on cost me 1100 to tow it down from a mountain getting no assistance from GMC other than they tell me one thing the dealer tells me another this is not the first time I've had problems with this it was in the shop from December through February no reimbursements no nothing nothing but problems since I bought it no help I've tried to do my best but my husband passed away at the time of all this was going on I could really use some guidance and some answers and what I should do they're telling me 8 to 10 weeks and they're not promising any kind of new warranty with this engine take what I have or buy an extended one from them that just doesn't right.

The dealer is telling me there is a faulty engine coolant, flow control valve on this vehicle and multiple other people are having the same issue. The part is on backorder and takes months to arrive. They are telling me I can drive the vehicle, but it becomes a safety issue because the engine thinks it is overheating and goes into reduced acceleration mode, which can impact safely driving the vehicle. Pulling out in traffic and not being able to accelerate can be extremely dangerous.

My telematics onstar unit went bad at 37,200 miles. No onstar, no sos, no hands free driving, etc. I paid roughly 3k for the extended subscription servies for three years. Like many others who have this problem, dealer/gm will not replace the faulty unit even though I still had time left on my on my subscription. Apparantly its a common problem.

Hi, I was driving on the turnpike 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. Thank you steve janosco.

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.

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.

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.

Truck will not fully shut off when turned off will say shift to park for 5/10 minutes after it is turned off finally drained my. 6 month old batterie.

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.

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 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.

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.

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.

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.

While using reverse camera system has burly image and grid lines in front and rear are missing with a light blue hour glass showing in the top left corner.

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.

My onstar module failed after 2 years, causing my check engine light to illuminate. The replacement has been unavailable for a year due to the large number of consumers fighting for a limited supply of replacement parts. This has placed myself and my passengers at undo risk as my ability to access the key safety features associated with onstar, including but not limited crash detection, emergency notifications, and location assistance. This problem was first diagnosed at bristol Chevrolet and then later inspected and confirmed at crabtree GMC.
