| Feb 2025 | AIR BAGS,SEAT BELTS | While driving a new 2024 GMC Sierra SLT (13,000), I received a prompt to SERVICE SAFETY RESTRAINT SYSTEM. My airbag lamp also illuminated and is now on. Upon researching this issue, it refers to potential failure of seatbelts and/or airbags. I have an appointment tomorrow at the dealership to have them diagnose the issue. | Crash: No Fire: No | Unknown |
| Feb 2025 | POWER TRAIN | The transmission would just give out. It also wouldn’t reverse. The cause was a faulty body valve that gm can’t produce fast enough. | Crash: No Fire: No | Unknown |
| Feb 2025 | ENGINE | 6.2 ecotec GM engine failed, it is available for inspection at the dealership. The engine failed while driving with no shoulder to pull over.

| Feb 2025 | UNKNOWN OR OTHER | Only owned my 2024 gmc sierra 1500 for 5 months close to 10,000 miles on odometer. Transmission valvebody failure. Gm and dealership says no ETA for a replacement part. Im hearing from other customers with same issue part will take 5-6 months for dealership to receive part. I have a brand new truck that im making truck payments on just siting at the dealership waiting for a transmission valvebody. This is unacceptable! There are many many GM customers dealing with this same issue. | Crash: No Fire: No | Unknown |
| Jan 2025 | ENGINE | was driving on the highway at 55mph and the engine just quit running and thankfully no one was near me and I was able to pull over on the side of the road. All the dash lights stayed on but the truck would not restart,code on dash board said "Conditions not correct for shift" Had it towed to the dealer and they put a new battery in it, but it broke down again on the way home same as before. Now they are telling me I need a brand new engine. | Crash: No Fire: No | Unknown |
| Jan 2025 | STEERING,ELECTRICAL SYSTEM,TRACTION CONTROL SYSTEM | The contact’s son owns a 2024 GMC Sierra 1500. The contact stated that after coming to a complete stop, the “Service Traction Control” message was displayed on the instrument panel. The contact turned off the vehicle and waited for a while before attempting to restart the vehicle; however, the vehicle failed to restart. The contact stated that the “Service Steering Column” message was then displayed on the instrument panel. A dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was 28,140. | Crash: No Fire: No | 28,140 |
| Jan 2025 | ENGINE | Truck with >15000 miles on it suddenly stops on highway (Dec 6, 2024). Engine won't start but all electrical components work, retractable steps, radio, bluetooth etc. When attempted to start, all electric went black and "push to start button again" came on display. Towed to dealer and after 3 days, advisor says it's not the battery but it might be something electrical. After six days I trade this truck in as they "don't" know what is wrong. After I trade they tell me that the truck needs a new engine but don't why. While taking my new 2025 truck in for a computer problem (500 miles) they tell me they found metal shavings in the oil. I find out two weeks later that there might be a problem with 877,710 6.2L engine with the same problem as mine. Sales says he doesn't know what problem is but he says he may be stuck with the truck for 30 days or more so I should trade. | Crash: No Fire: No | Unknown |
| Jan 2025 | ENGINE,FORWARD COLLISION AVOIDANCE | 1st time Complete failure on my 2024 engine without warning. As I was traveling on the interstate. All of sudden, I lost all power. Mt truck started slowing down on its own. It was very difficult getting out of the way of on coming traffic. Dealership replaced values. 2 months later. Again on the Interstate engine complete failure again. Now take it to dealership. This time I heard a ticking noise. Right after the ticking noise. Engine stop working. Same situation. Trying to get out of the way of traffic. I was stranded over 3 hours. | Crash: No Fire: No | Unknown |
| Jan 2025 | ENGINE | On 01/24/2025, I was driving my GMC Sierra in the express toll lane at approximately 75 mph. The toll lane had two lanes and was enclosed by concrete barriers on both sides with no median or shoulder to pull over. Without warning, the engine suddenly shut off. There were no warning lights, no unusual noises—just complete engine failure. The power steering also stopped functioning, making it difficult to control the vehicle. I immediately shifted into neutral and focused on keeping the wheel steady to avoid triggering the wheel lock, which could have caused me to lose control and crash. I was forced to coast to a stop, barely managing to find a narrow sliver of space on the median of an on-ramp to the express lane. However, even then, my vehicle was still partially blocking the right lane of the express toll lane and partially in the on-ramp. There was nowhere safe to go, no way to restart the truck, and I couldn’t exit the vehicle due to high-speed traffic surrounding me on both sides. I sat in my disabled truck, utterly exposed, fearing for my life as cars sped past me at 70+ mph. I kept imagining the worst—that an inattentive driver would slam into me, causing a catastrophic accident. Thankfully, after several harrowing minutes, a police officer arrived to block traffic behind me, and another cruiser blocked the entrance to the express lane. Only then did I feel a shred of relief. This was one of the most terrifying experiences I’ve ever endured, and I wouldn’t wish it on anyone. Afterward, I learned that my 6.2L L87 engine had spun the main bearing and now requires a complete engine replacement. In researching this issue, I discovered that the NHTSA is already investigating similar failures in vehicles equipped with this engine. Alarmingly, I also spoke with my Uber driver on the way home, who told me he experienced the exact same failure in his 2023 Escalade with the 6.2L engine. Thankfully, his failure occurred at a red light rather than at highway speeds | Crash: No Fire: No | Unknown |
| Jan 2025 | ENGINE | I purchased this vehicle new in August of 2024. Approximately 2 months ago when the temperatures outside temperatures started falling below freezing, I would frequently get a message, "reduced acceleration, drive with care" pop-up on the center screen, and the check engine light would illuminate. This happens almost every time the outside air temperatures are below 28-30 degrees. Occasional the truck engine loses power and acceleration, but not always. This code pops-up regardless of the engine temperatures. It has been to the dealer where I bought it each time, and they state that GMC told them it is normal. They reset the computer, and the check engine light goes out until I run the truck in temperatures below 30 degrees. The dealer has been great with me, but dealer reports GMC will not cover their services under warranty as GMC reports this is normal. This condition happens unannounced and almost all the time in cold temperatures. It has happened at least 12 times. The performance can be a safety issue when this condition comes about, and you're driving in traffic. I opened a case with GMC on Thursday, January 16, 2025. It is case number [XXX]. I spoke with Graham, the customer service representative who reported that this issue will be escalated to the regional CE Manager because of the frequency that this is happening. Graham reported to me that this CE Manager will be in touch within 2 business days which would be Monday, January 20, 2025. I received a call mid-day on Wednesday January 22, 2025 from a woman from General Motors. I was at work at my full-time job and could not speak very long. I asked if she could call me after 4:30 PM when I was done working, and she replied "sure, we can make that happen." She advised me to get my truck to the dealership. My truck has been at the dealership since last week. As I am typing this, I just received a call from a Christian. Please review attached pictures, and call if you need elaboration. [XXX] .

| Jan 2025 | ENGINE | I was driving on the highway and my truck went black and engine stopped no power to truck. It was very scary. I pulled over and it was in Neutral and somehow got it into park. The car never would turn over. The truck is at midway motors with metal shavings in the engines. They say it locked up and needs replaced. GM is very difficult to work with and won’t give us any information. I’m scared of the truck. | Crash: No Fire: No | Unknown |
| Jan 2025 | ENGINE | I was driving my truck on Friday, [XXX], at approximately 50 m.p.h. The tires suddenly locked up and skidded momentarily and then released. Then a very loud clanging noise started in the engine. I lost power and coasted to the side of the road. Then the engine stalled. The truck was towed to Keeweenaw Chevy/GMC in Houghton, Michigan. I was later contacted by the Service Department and informed that the engine had indeed blown and a new engine would need to be installed. Engines are on LONG backorder. I was lucky I wasn't traveling 65 m.p.h or on snow covered roads, as this incident could have then resulted in a complete loss of control and hitting a logging truck head on.

| Jan 2025 | ENGINE | Driving on hwy at 65 mph truck shut off without warning and display said shift to neutral and push start. Truck wouldn’t shift and nothing worked. Coasted to the shoulder where I sat for 5-6 hours waiting for a properly equipped tow truck. Motor was seized. | Crash: No Fire: No | Unknown |
| Jan 2025 | ENGINE | While driving my truck it suddenly lost power. The truck had been operating normally with no prior issues before it shut off without warning. The truck was towed to a local dealer where they later told me the engine had seized up and needed to be replaced. The truck is a 2024 model that I had purchased new two months earlier. It only had 4,533 miles on it. I was driving at highway speeds and had to coast into a gas station parking lot. I was able to coast to safety, but losing power at highway speeds certainly increases the chance of having an accident. | Crash: No Fire: No | Unknown |
| Jan 2025 | ENGINE | The motor seized up, while driving, no warning lights, just died, had towed to the dealership and was told the motor had seized up, it has now been at the dealership for 45 days, I am being told that there is not a new motor available to replace mine | Crash: No Fire: No | Unknown |
| Jan 2025 | POWER TRAIN,ENGINE | On December 25, 2024, my vehicle completely stalled in the middle of the highway while travelling at 65 mph. Fortunately there were no vehicles travelling in close proximity to me at the time as my speed rapidly decreased. The abrupt stall required me to pull over to the side of the road to attempt to restart. I was unable to restart the vehicle despite numerous attempts. Jump starting was also unsuccessful. I was left stranded 90 miles away from home in freezing temperatures during a snowstorm on Christmas night. My vehicle was towed to a dealership 140 miles from home as GM would not cover the cost of towing to the dealer closest to my home (68 miles away). After numerous phone calls with GM as well as the GM dealer, I was informed 9 days later that my entire engine (6.2L V8) would need replaced. I was also informed that there are two vehicles ahead of mine that require replacement of their engines and that the engines are back-ordered. They have been unable to provide an estimated timeframe on when my vehicle will be returned to me in working condition, stating it "could be months." When I was informed of the need for an engine replacement, I placed a request for a manufacturer repurchase which was ultimately denied the following week. The agent responsible for managing my case informed me that "GMC requires two to three major failures" before they will consider a repurchase approval. The dealership was not able to provide me a loaner vehicle and I was informed that GM only reimburses $44 per day toward a rental vehicle. My occupation and location require reliable transportation in harsh winter conditions so a truck is the only reasonable option. The dealership charges $75 per day to rent a basic truck. Prior to this incident, the vehicle did not have any major issues and received routine maintenance services as recommended by the manufacturer. It was never involved in any accidents. It only had 17,553 miles and was purchased brand new in October 2023. | Crash: No Fire: No | Unknown |
| Jan 2025 | UNKNOWN OR OTHER,ENGINE | November 15 I was driving home from work as the truck started jerking. The system was giving me an engine failure drive with caution warning. I pulled over and decided the turn off the truck and turn it back on. Once I turned it back on it was revving on its own. I decided to turn it off again and it stopped revving but the gears would not shift. You were physically able to switch them but as much as you pressed on the gas to reverse it would not. I had to have it towed to the dealership I purchased it at. It has been 3 months and the part that is needed is still on back order. I placed a compliant with GM and they opened a case but nothing has happened yet as far as getting an ETA on the part. | Crash: No Fire: No | Unknown |
| Jan 2025 | UNKNOWN OR OTHER | Tailgate comes open without wanting too. Few times I've come to find the truck with the tailgate open, has occurred twice while driving. There is a recall for the same issue with the 2500 and 3500 series GMC Sierra. My truck is a 1500 series GMC. Surely same issue and faulty tailgate lock as the 2500 and 3500 trucks. | Crash: No Fire: No | Unknown |
| Jan 2025 | ENGINE | I was waiting in a parking lot to pick up the kids from school. In park, the truck loses power and almost completely shuts down. When it Reva back up there was a horrible hammering noise. I turn the truck off. Then I called the dealership and told them. I cranked it and recorded it for them and then shut it off. Then the tow truck couldn’t tow and it took two hours to get it loaded because of the features locking things down. It has been 29 days before the finally told me it needs a whole new engine. They still will not tell me why though. | Crash: No Fire: No | Unknown |
| Jan 2025 | ENGINE | Engine started making noises. I had it towed to dealership to get it diagnosed. Dealership called me next morning to get information on what vehicle was doing. I called dealership that same evening and they informed me that the engine locked up on the tech diagnosing the issue, and I was going to need a new engine. | Crash: No Fire: No | Unknown |
| Jan 2025 | ENGINE | 29K and I have metal shavings in the oil/lifter tick failure. T | Crash: No Fire: No | Unknown |
| Jan 2025 | ENGINE | Since brand new, the engine makes a significantly loud chirping sound at two occasions. First is every time the fuel saving auto start kicks in to start acceleration. The other is any time you come to a stop from above 25-35 MPH. At around 16 MPH, there is a loud chirping as you decelerate. This appears to be a timing malfunction and is affecting fuel economy. The vehicle has 8,800 miles on it, and it is getting worse. It has been looked at 4 times and has not been identified. I know there was a GM bulletin from 2022 about this 6.2L V8 Engine, but they state it is "normal". I have never heard a normal sound of this kind from an engine. And certainly not on a $75K vehicle. Please investigate and make them correct the issue or replace the engines. people work too hard to afford nice vehicles, and should not have to deal with this issue. | Crash: No Fire: No | Unknown |
| Jan 2025 | ENGINE | My truck was put on an engine oil consumption plan at ~14,000 milee. Then a month later the engine complete seized while i was driving at 60 mph in the middle of southeast Missouri. The dashboard started flashing with a warning saying that I needed to press the start button. The vehicle came to a stop and i was unable to get it to turn over. I currently have a warranty claim with GM amd the vehicleis at Laura GMC in Collinsvill, IL awaiting a replacement engine. I have no confidence in GMs ability to fully resolve the issue. My life has been completely disrupted as a result of their lack of quality controls. | Crash: No Fire: No | Unknown |
