2024 GMC Sierra 1500

On 29 November 2025 at approximately 1700hrs, I was driving my Blue 2024 GMC Sierra 1500 AT4X outside of Pampa, TX. As I was driving to my hunting location, my truck turned itself off and placed itself in neutral. I was driving about 30 mph down a single farm road with another vehicle approaching me from the front. I was unable to pull to the side due to farmland. I was able to flash my lights to get the other vehicle to slow down before having an incident. During this time, I had to let the truck slow down to a stop. My vehicle was already inspected for the engine recall and I was informed I had nothing to worry about. That everything was good. The truck is at Greg Lair in Canyon, TX. It did put me and my passenger as risk. I did not receive any warning before my truck turned off. The dealer confirmed today that the engine had seized. The engine was inspected during the summer before this issue. I had not warning when this happened. Was just driving and lost power. Looked down at the display and it stated to restart engine. I noticed my truck was in neutral when it came to a stop.

The recall you are showing was completed 300 miles ago. There were no outstanding recalls on my vehicle on November 23, 2025. On this day I was driving home, at night and I heard a loud flapping sound coming from the front of my vehicle. I pulled over and checked the front and wheel wells, nothing was stuck. I got back in and started driving the flapping sound was coming as I pressed the gas, when coasting with no gas, there was no flapping sound. I managed to make it home and GM towed my truck the next day. The shop has informed me that the engine is gone. Even though I did the recall 300 miles ago, it was directly what they were looking for in the recall and did not find it. This clearly put me in danger.

After pulling my 2024 GMC Sierra 1500 SLT into a parking space at a local store, I shut off the engine. I observed the lighted ignition switch and the dash icons were illuminated even though the engine was completely off. Having had my foot on the brake at the time I decided to test the ignition switch to determine why it was lit while the engine was off. When I pressed the start button there was a loud, whining starter like sound, grinding like metal on metal. The noise was so alarming that I immediately took my hand off the ignition. The engine was still off. After waiting a significant amount of time I tried to restart the engine. Exactly the same thing occurred. On the final attempt to start the engine, 15-20 minutes later, it started and ran quietly like nothing had ever happened. On returning to the vehicle my wife asked what all the loud grinding noise was about. She had heard it while she was inside the store. I advised her it was our truck! The incident was shocking to us both and because of its bizarre nature I was afraid to drive the vehicle back home. As I already had an appointment on November 6 at DeLuz Chevy for another incident, I called them on November 3 to add this incident to the existing appointment. This incident was added to the November 6 appointment. Unfortunately the service department did not assess the previous incident and only addressed this incident.

I was operating my GMC Sierra 1500 SLT in Hilo HI. As I was slowly turning left from [XXX] onto [XXX] my vision was drawn to the rear view mirror. My wife and I observed a huge smoke like cloud above the tailgate of my truck and beyond. I immediately reduced my already slow speed. Traffic was heavy and I was unable to safely assess the problem on the spot. When I arrived at my destination a few blocks away I found no physical evidence that it had occurred. It has not happened since. Even so, we were concerned enough to make an appointment with DeLuz Chevy in Hilo for assessment. Unfortunately in the interim I experienced another problem with the truck and asked that it also be addressed during the smoke related appointment. Again unfortunately the DeLuz service department did not assess the smoke incident during the service visit.

On August 3, 2025 I was on the road enroute to my residence. With no warning my 2024 GMC Sierra 1500 SLT engine quit. We heard a popping sound and the entire vehicle shuddered. I took safe control of the vehicle. As I intervened I noticed that the dash warning lights were lit. Almost immediately the warning lights went off and the engine restarted on its own. We were startled and extremely concerned about what had just happened. This was the first problem we encountered with the truck. I contacted the DeLuz Chevy garage in Hilo for a follow-up appointment.

The contact owned a 2024 GMC Sierra 1500. The contact received notification of NHTSA Campaign Number: 25V274000 (ENGINE AND ENGINE COOLING). The contact stated that while driving at 16 MPH, the engine suddenly stalled. No warning lights were illuminated. The contact was able to restart the engine, placed the gear lever on neutral(N), and revved up the engine. The contact then moved the gear lever to drive(D); when the vehicle accelerated independently, the contact swerved to avoid hitting a telephone pole, then swerved to avoid hitting a mailbox, and ended up hitting a tree, where the vehicle came to a stop. The driver-side and passenger-side air bags. A police report was filed. The contact sustained minor injuries to his foot. No medical attention was provided. No passengers in the vehicle. The vehicle was towed to a collision center. The vehicle was not inspected. The insurance company was notified. The manufacturer was made aware of the failure and pending an investigation. The failure mileage was approximately 25,000.

On October 23rd at approximately 0900-0915 hours I arrived at a friends house located at [XXX] . As I normally do, I pulled up into the driveway which has a pretty significant incline. I shifted the column shifter into park, and turned off the vehicle via the push button ignition switch. The parking brake/hill brake system automatically engaged as per normal operation. I exited the vehicle and before I could shut the door, the vehicle began to roll backwards. The driver's side door hit me in the right shoulder which pushed me to my left and caused me to roll my left ankle due to the down slope of the driver way. While I felt immense pain in my right ankle, I was able to jump back into the truck and slam on the brakes, causing both rear wheels to lock up and skid in the driveway. I then turned back on the vehicle, noting that the transmission position was still in park, and the parking brake/hill brake was still engaged. I had to disengage the push button parking brake/hill-brake, shift the vehicle from park into drive to move back up the driveway. This time I ensured that the vehicle did not move after following the exact same steps. My truck under went an approximately 30 minute software "upgrade" approximately 2.5 weeks ago. I believe there was an issue where the park sensor did not fully engage, leading the vehicle to believe it was still in an operational gear, however it does not explain how it was able to not only over-ride the parking/hill-brake itself, as well as allow me to shut the vehicle off and exit the vehicle. This safety hazard has caused me an injury that has already caused me to miss 48 hours of work (I am a federal firefighter) and will require more missed time should surgery be required. There were no warning lamps, the backup camera was not engaged, the only audible sound was the beep that the vehicle makes when engaging the parking brake automatically.

The first time the truck stopped and wouldn’t want to start (engine light came up) after a few minutes and with a push the truck turned on. Next day while driving on freeway the truck shift hard pulling vehicle back as if it was going to stop without braking. Took truck to GMC dealer on 9/26/25 for an inspection with approx 17,000 miles. Oct. 17, 2025 GMC rep said my truck was inspected/ good to go and was ready for pick up. Not sure what part they had replaced. On Oct. 18, 2025 picked up truck while leaving dealer I had my family in my truck about 3 miles into my drive we heard a loud clunk and the truck shifted hard slowing the truck down and display reduce acceleration drive with care and check engine light on. Have in mind we were on a busy traffic street driving while other cars had to pass us because we couldn’t speed up. I did not feel safe with my children in the car, left it again for the 2nd time with GMC service dept. Now we are almost reaching to a 30 day grace period without our vehicle.

GM has identified my vehicle as having a problem "If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash.". It has been almost 6 months since this issue was identified and yet GM has failed to address the issue in my vehicle. I believe this problem should be immediately corrected and if it results in my or my families injory GMC should be considered grossly negligent for their failure to promptly correct the issue.

I received a letter from GMC almost 4 months ago telling me that my 2024 GMC Sierra 1500 was recalled due to an engine safety issue. The letter stated that there was no remedy yet and that a subsequent letter would be sent with instructions on how to have repairs done. I never received a second letter. Also, my GMC app stated that the vin had an incomplete recall. Today the app states that there are no incomplete or completed recalls. I called my dealer and they said they know nothing about the recall and I should just wait. This is unacceptable and I need some type of resolution.
