I passed the recall inspection on 12/17/2025 and the higher viscosity oil was put into my vehicle. On 12/25/2025 my vehicle's engine shut off while I was traveling on the highway (I-25). The vehicle went into to neutral and I had to pull over to the side of the highway without power. The vehicle started again and as I was merging onto the highway it shut down again. The truck started again and I was able to drive it home. There were no codes found when I took it in for service on 12/26/2025. On 01/24/2026 I was driving on the highway (us-40) and I had complete engine failure. I had to get my vehicle towed to the service center and a new motor was installed. On March 27th the vehicle's engine shut off again while driving on the highway (us-191). There were no codes or check engine lights on this time either. The service records state that the starter mount stud was loose.
12/7/2025 8:48 am engine lost propulsion while driving 35mph enroute to residence. The engine cut off and at the same time we saw a cloud of blue smoke trailing the vehicle. The engine refired and propulsion resumed. I immediately looked at the dash display for an indicator light resulting from the lack of propulsion. There were no unusual indicator lights or messages but the tachometer needle dropped about an inch and went back up again rapidly. The engine had resumed running. This loss of propulsion and resumption occurred two more times while my foot was off the accelerator. After the third incident the vehicle seemed to be running normally. I stated we had only about two miles to get home and I hope we make it. The next day I called deluz service department to notify them of the incident. I left a message but my call was not returned. I updated service staff of the new incident when I dropped the vehicle off for a previously scheduled appointment on 12/11/25.
While driving my 2024 GMC sierra denali ultimate on the highway, the engine suddenly failed without warning. The truck shut off completely while I was traveling at highway speed. I was fortunate to be able to safely maneuver to the shoulder, but the sudden loss of power created a serious risk of a collision with surrounding traffic. The failure appears to involve the engine or engine control system. The vehicle engine is currently available for inspection upon request. Prior to the incident, there were no warning lights, messages, or unusual symptoms. The shutdown occurred abruptly with no prior indication of a problem. This vehicle previously received the ns25249400 safety recall repair on August 12, 2025, and it reportedly passed all required checks at that time.
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. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
My wife and I were traveling on a county road and without warning, the vehicle skipped twice and cut off in the middle of the roadway in a sharp curve with rain threatening at approximately 7:30 p. M. Et August 11, 2025. I attempted to restart numerous times because we were in the middle of the right lane. The starter would spin but vehicle would not restart. The truck then would not shut off and draining the battery. I called for a wrecker and the sheriff's office to keep somebody from hitting us. Before the wrecker came, we connected a diagnostic device to the vehicle indicating it was the fuel pump module. 0august 12, 2-25, I called gm roadside assistance to be towed to closest dealership. The driver said he was familiar with a lot of gm trucks with the same issue. The vehicle has less than 12,000 miles and was purchased in June, 2024.
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.
On may 14, 2025 this vehicle was in blue cruise on I-12 in louisiana when it without warning coasted to a stop after the engine quit. Cruise lights remained active, no other lights were illuminated, and the vehicle simply rolled to a stop. La. Dot assisted. The vehicle was towed (complicated that once placed into park, and the engine would not restart, the vehicle cannot easily be placed in neutral to be towed). The vehicle was trailered some ~50 miles and sits at rainbow northshore GMC in covington, la. This is a series, life threatening situation that all vehicles need be removed from the road.
While exiting the highway and transitioning into a turn lane, my 2024 GMC sierra at4 (with 12,887 miles) suddenly and completely shut down without any prior warning. All vehicle systems—including electrical—failed simultaneously. This included the dashboard, steering assistance, and emergency lights, which significantly compromised my safety. I was unable to alert surrounding drivers or move the vehicle out of the traffic lane. There were multiple cars behind me, and I was placed in an extremely unsafe situation due to the sudden loss of control and inability to signal or restart the vehicle. I immediately contacted emergency services, and a police officer arrived approximately 10 minutes later to assist. Roadside assistance later pulled diagnostic code p0016 from the truck’s computer. I have since learned that this code corresponds to a known engine timing defect and is the subject of a recent GMC recall issued just days prior to the incident. The failure occurred without any warning lights, messages, or symptoms beforehand. The vehicle is now with a GMC dealer and is available for inspection upon request. To my knowledge, the issue has not yet been independently confirmed, but I believe it is directly connected to the recalled component.
I leased a 2024 GMC Sierra 1500 denali ultimate with the 6. 2l v8 engine. The vehicle experienced multiple engine-related issues over time, including stalling on [xxx], and again in early 2025. On [xxx], the engine completely failed while I was driving on the highway. The truck suddenly shut down, forcing me to pull over in a dangerous situation. It was towed to north bay Cadillac, where they confirmed the engine needed to be fully replaced. They also stated this issue is related to a known engine defect affecting 6. 2l engines across gm vehicles. The vehicle has been in the shop for extended periods and is currently undergoing repairs estimated to take over a month. Gm provided a loaner vehicle after 12 days, but I remain financially responsible for a defective truck that posed a serious safety risk. No warning lights were present before the failure. I am requesting that this issue be formally documented due to the severity of the safety hazard and the widespread nature of this engine problem. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
My truck completely stalled and had to be restarted. I took it to the dealership to have it resolved. They wouldn’t look at the truck without a recall notice. Now there is a recall notice for my exact issue. I took it to be repaired by them but now they are saying that there is nothing wrong with the vehicle and are refusing to do anything about it stalling. They specifically said that I will have to stall and potentially get in a car wreck before they will repair the damaged engine. I have been very disappointed in this entire situation and would like to avoid driving a car that may end up crashing due to a preventable problem.
