There was no warning light illuminated. The contact coasted to a stop in the shoulder lane and allowed the vehicle to sit for several minutes before attempting to restart the vehicle; however, the vehicle failed to start. The vehicle was towed to a local dealer where the vehicle was diagnosed, and the contact was informed that the engine had seized and needed to be replaced. The vehicle was not repaired.

| Mar 2025 | ENGINE | Was driving approx 70 MPH when the truck lost power and put itself into neutral. Had to pull over on busy [XXX] in Missoula at 15deg F. Truck display said "restart vehicle". Once pulled over, truck put itself into PARK. Truck would not restart after multiple attempts. Was towed to dealer where they stated the engine may have seized.

| Feb 2025 | ENGINE | Engine failed at 10,000 miles while driving down the road. No warnings, engine shut off while driving. I pulled over and contacted OnStar. They got me a tow truck to bring the truck back to the dealer the next day. I was told that I needed a new engine and they don’t know when they’re gonna get one in. It could be months. I had to pay for a Rent-A-Car out of my own pocket. The dealer would not cover the cost. | Crash: No Fire: No | Unknown |
| Feb 2025 | EXTERIOR LIGHTING | Back up camera is almost useless in very dark situations. Back up lights on vehicle wash out the view and all you can see are the red marker lines. Needs either brighter back up lights or a better camera definition. You cannot see a children's bike or other things while trying to back up. | Crash: No Fire: No | Unknown |
| Feb 2025 | ENGINE | I am beyond frustrated with my newly purchased 2024 GMC Sierra Elevation 1500 5.3l V8. Back in November I was notified to bring my vehicle back to the dealership for a complete engine replacement. Ever since this time I have had continuous problems with the vehicle. One day after receiving my truck back, I noticed that it was running rough and misfiring. When I opened the hood, I observed a bungy cord still attached to the engine. Several weeks after, the check engine light came on and took a week to get back due to sensor issues with engine. Today, after getting off work, I turned on my truck, but I am unable to shift out of park and I am stuck waiting on a tow truck. There has been nothing but issues with this truck since they replaced the engine. I am not sure if the mechanics at Garlyn Shelton GMC in Temple, Texas, are qualified to replace engines. This is a brand new truck and I should not be having these issues. My fear is that these problems are going to continue because they either did not properly install the new engine or there are still defects. | Crash: No Fire: No | Unknown |
| Feb 2025 | ENGINE | At 14,000 miles the engine seized. Car stopped on a busy highway almost causing a collision with other vehicles | Crash: No Fire: No | Unknown |
| Feb 2025 | POWER TRAIN | First time it happened was on November 28th 2024 around 8pm, turned de engine on, selected the reverse gear and stepped on the gas, the reverse gear was selected but the gear didn't worked at all. I almost hit a car that was passing on the street. I out the gear on drive and got the message "reduced acceleration". I believe that is a known issue by GM's 10 speed gearbox. The car is at the dealership and they informed me by e-mail that the part transmission valve body is in a "do not sell list". I have concerns about safety because losing power on a 70miles per hour road can be dangerous and not being able to reverse is also very dangerous. There are tons of posts about it in Facebook. | Crash: No Fire: No | Unknown |
| Feb 2025 | ENGINE | 6.2L V8 engine failure | Crash: No Fire: No | Unknown |
| Feb 2025 | POWER TRAIN,VEHICLE SPEED CONTROL | I have experienced several occurrences of unintended acceleration while operating the vehicle at low speed. Two recent examples; 1) the truck accelerated rapidly while I was driving into my garage, and 2) the truck accelerated suddenly when pulling forward out of a parking spot in the morning shortly after starting the vehicle. In all cases, a hard application of the brake pedal slowed the vehicle. I considered whether this was operator error, possibly engaging cruise control inadvertently while turning the steering wheel, but the incident this morning does not support that potential cause. I have not spoken to the dealer about this issue. | Crash: No Fire: No | Unknown |
| Feb 2025 | STRUCTURE | Since my purchase of the vehicle Dec 2023, the tailgate opens on its own. Usually follows hitting a bump such as the rain gutter entering a store parking area. I have also had it occur while driving down the road. Have been told multiple times by my service personnel they have had same complaints from other Sierra 1500 but have no fix for the problem. They have offered to deactivate the electronic tailgate system but this is unacceptable to me. There is a recall for 2500 models with same issue but not for 1500’s. This makes little sense. | Crash: No Fire: No | Unknown |
| Feb 2025 | POWER TRAIN | The contact owns a 2024 GMC Sierra 1500. The contact stated while driving 74 MPH, the vehicle inadvertently lost motive power, after which the vehicle was unable to accelerate above 25 MPH. The contact was able to pull over to the shoulder of the roadway and turned off the vehicle. After restarting the vehicle, the vehicle returned to normal functionality, but the failure became a regular occurrence. The check engine warning light was illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the shift solenoid valve and that the serial data gateway module needed to be reprogrammed. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 24,000. | Crash: No Fire: No | 24,000 |

| 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 | ENGINE | Since owning my truck new, the vehicle has had numerous issues with loose exhaust and engine components. The truck has had loose catalytic converter bolts, heat shield and exhaust components causing severe vibration in the driveline, dash and floorboard.

| 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.

There are many many GM customers dealing with this same issue. | Crash: No Fire: No | Unknown |
