POWER TRAIN
Upon exiting the freeway, I pressed the gas and the vehicles rpm’s went up to 4K plus on a diesel engine, no acceleration. Thought maybe there was ice and had lost traction, tried again, same thing. Then a shudder, bang and pop. The check engine light went on and informed me of limited power and acceleration. There was no acceleration. Rpm’s would go to 2000 plus just to move. Got it to the dealership and parked it. Made a service appointment. They tried to put it into reverse and it wouldn’t move.

BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING, VISIBILITY/WIPER, EXTERIOR LIGHTING
The backup camera in the dark on this vehicle is unusable. Someone will eventually run someone over. I have added brighter lights everywhere on the back of the vehicle and the camera is still useless at night. The dealer told me it looked fine to them (they checked it in a lit garage). There are hundreds of complaints across all forums.

ENGINE
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.

ENGINE, FUEL/PROPULSION SYSTEM, EXTERIOR LIGHTING
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.

ENGINE, FUEL/PROPULSION SYSTEM
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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ELECTRICAL SYSTEM, ENGINE, FUEL/PROPULSION SYSTEM
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.

ENGINE
The engine oil drained into the radiator from a flaw in there design in which outrageously high labor cost for the owner of the vehicle they put a rubber house in the radiator in which leaked without any warning indicating that there was a problem with the oil nor the radiator coolant system. repairs are in the thousand and I as a consumer should have this matter resolved at no cost due to bad design cost they should have made a oil cooler with its own separation compartment like the transmission cooler because they are replaceing everything else what about the engine itself thats still going to be contaminated like all the replacement part, seal hoses,and radiator, coolant, and thermostat. How can just parts be contaminated but not the engine? They are just replacing things that costs alot. This is a drive train issue, there were no oil in the engine.

POWER TRAIN, UNKNOWN OR OTHER, ENGINE
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.

LANE DEPARTURE: ASSIST, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
SuperCruise Repeatedly crosses Double yellow lines even with on coming traffic. Sometimes with SC active it will make an auto lane change but halfway through it will randomly swerve into either lane, or just simply turn off without warning. It started happening after a software update in May of 2025. We have provided GM and the dealership with Video evidence, along with the dealership mechanic replicating the problems. GM states that SC is operating as intended and that we are not to bring the truck in for service for that issue again. they denied buy back twice now.

ELECTRICAL SYSTEM, EXTERIOR LIGHTING, SERVICE BRAKES
This vehicle exhibits the same failure described in NHTSA Recall N232426400 — spontaneous unlatching after rain due to water intrusion into the exterior tailgate release switch. I’m requesting a goodwill replacement under GM bulletin # N232426400 as the failure mechanism and part are identical. It has caused brake failure and nearly killed me because of battery drain while driving. All American Chevrolet of Midland Texas is refusing to solve the problem and says no recall is available.

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.
