VISIBILITY/WIPER, UNKNOWN OR OTHER
My issue is with my back up camera being useless in low lighting and dark situations. I live in a dark community sometimes and I cannot use my back up camera to get me down my driveway without opening both front windows. I had a 2016 GMC Sierra and I had no problem with it. I first brought it into the shop with this issue and they replaced the camera and that did nothing. The 2nd time I brought it in for the camera issue, they said it is a software issue and they are waiting for a fix. (That was back in June) I called GMC Customer care and opened a case, but that is falling on deaf ears as they are saying there is nothing they can do. They tell me to keep waiting on the dealership for the fix. My Daughter, son and friends are having the same issue, but they are adding additional lights. I refuse to do that, as I think GMC should take care of it.

SERVICE BRAKES, POWER TRAIN
Problem #1: Trailer brakes failed while pulling 40' fifth wheel trailer. Was driving at about 50MPH on a 55MPH road and was approaching a stop light. I went to apply my truck and trailer brakes simultaneously and quickly found out I had "lost" my trailer brake. This happened another two times within the next 10 mile trip to my house. I immediately disconnected my trailer and took my truck to the shop. The GMC Dealer fixed this issue, however, it is both scary and extremely dangerous to the public when something like this happens on a brand new truck. Problem #2: Right around 30,000 miles I was driving (unloaded) down the road at about 35MPH when I felt a hard clunk in the transmission followed by grinding noises - immediately a notice flashed on the dash stating the truck went into reduced acceleration and the check engine light came on. I brought my truck to a local GMC Dealer to be serviced on June 19th and they advised me it was the Allison transmission valve body. The part has been on back-order and my truck is still at the dealership sitting in the back lot with at least 4 other 2024 HD models. I called GM twice to inquire about Safety Recall N242454440 (covering 2020-2022 GM Vehicles) and recommend that it get extended beyond 2022 since the problem with the transmission valve body has not been resolved yet. I have not heard anything back from them since that call back in June.

During a drive home, while in motion, the tailgate of the vehicle opened on its own. This has occurred after the recall to repair this issue was already performed. I know the tailgate was shut prior to the drive because I back into my parking spot and walk the sidewalk behind my truck prior to starting the vehicle.

Loss of audio throughout an entire drive/ignition cycle. This includes the loss of the blinker click/clack audio when the blinker is on. When the loss of audio issue occurs, the driver has no audio input indicating a blinker is on even though the actual blinker is flashing to other drivers. Therefore, an unaware driver (due to no audio feedback) with a blinker left on could have another driver pull out in front of them thinking they intended to turn with the result being a collision.

ENGINE, ELECTRICAL SYSTEM
On [XXX] while traveling on a highway, the vehicle lost drive power—the gear selector would not remain in Drive and reverted to Neutral for approximately 10 minutes. This created a serious safety hazard due to sudden loss of propulsion in moving traffic. The event was captured by OnStar, which emailed an automated incident alert. I later received a GM safety recall notice concerning potential engine loss of propulsion for vehicles with the 6.2L L87 engine (NHTSA 25V-274 / GM N252494000/001/002). I presented the vehicle to Ewing Buick GMC (Plano, TX) on July 23, 2025 for recall service and retrieved it on July 28, 2025. Approximately one week later, during an interstate trip to Kansas City, the engine catastrophically failed about one hour from my destination, leaving the vehicle disabled on the roadway shoulder. Roadside assistance towed the truck to Briggs Auto (KS). Briggs Auto diagnosed engine failure and ordered a replacement engine. I was informed the engine is on back-order with no estimated arrival, and the shop is under-staffed, prolonging repairs. The vehicle remains out of service. The sequence—pre-recall loss of propulsion, post-recall service, and then engine failure within a week—shows a serious safety defect that can lead to sudden loss of power at highway speeds, risking a crash. Frequency: Loss of propulsion occurred at least twice (March highway incident; subsequent engine failure in early August). Warning Lights/Messages: [Gear refuse tom shift to Drive mode.] Injuries/Crashes: None, but risk was substantial due to sudden power loss. Dealer Involvement: Ewing Buick GMC (recall visit); Briggs Auto (diagnosis/engine order). Attachments/Supporting Docs: OnStar email, recall notice, repair orders, tow documentation, photos/video. Please investigate whether 2024 GMC Sierra trucks with the 6.2L L87 engine continue to pose a loss-of-propulsion risk after recall service and whether parts shortages/back-orders are delaying effective remedy INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION

The contact owns a 2024 GMC Sierra 1500. The contact stated that while vacationing in Canada and driving at various speeds, the vehicle jerked, and the vehicle failed to accelerate as intended while depressing the accelerator pedal. In addition, the RPM fluctuated, and the engine revved abnormally. The contact stated that the vehicle failed to reverse(R) as intended. The contact was able to coast to the side of the road while in LIMP Mode. The vehicle was towed to a dealer, where it was diagnosed, and it was determined that the transmission had failed and needed to be replaced. The contact was informed that when the dealer contacted the manufacturer to order a new transmission, the manufacturer refused and informed the dealer to repair the current transmission. The vehicle was repaired. The contact stated that a week later, the vehicle experienced another failure. The contact stated that on a separate occasion, while approaching a stop sign, the brake pedal was depressed, and the engine revved unintendedly. The contact used force to depress the brake pedal. The failure persisted. The vehicle was taken to a dealer back in the USA; however, no cause for the failure was found. The vehicle remained at the dealer unrepaired. The manufacturer was notified of the failure and was awaiting the results of the diagnostic test. The failure mileage was approximately 9,000.

On 22 April I turned my truck in to the dealership service department due to recall of the L87 6.2L engine. Also, told the rep, "my truck was shifting hard". After inspection revealed the valve body needed replacing. My vehicle is still at the service department today with no remedy in sight. I asked if Gm could just replace my transmission because, the part is not coming. They explained they would replace the transmission, but they can't find a 10 speed transmission available to swap out. I call weekly to get updates. nothing!!

This is my 4th GM 3500 dully and the first time with this kind of problem. I took my truck in for inspection and it came back with a clean bill of health about 25,000 miles on the 2024. When I got it back I noticed a vibration when breaking. I took the truck back in to find it had bluing on the rotors and the break pads have holes in them. I was told this came from over heating. I looked up info to see if this was a common problem and found the in 2022 GM changed the material to help with noise problems and this material had been know of premature break problems. I called GM customer service and they told me to work with the dealership, the dealership called the district manager and all parties have decided to ignore the issue. I also have 2 of these truck driven by 2 different people with the same problem at the same millage. I will make a 2nd report for the 2nd truck.

I just bought my truck a 2024 GMC 3500 and in a few weeks after purchase. I took my truck in for a break vibration. I took the truck back in to find it had bluing on the rotors and the break pads have holes in them. I was told this came from over heating. They said it was missed on the pre sale inspection they did. I looked up info to see if this was a common problem and found the in 2022 GM changed the material to help with noise problems and this material had been know of premature break problems. The dealership denied doing the work under warranty.
