Sierra 1500

  • miles
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 [XXX] this vehicle was in Blue Cruise on [XXX] 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.

I have received the notice about the recall and now I am just worried because I have a wife and two-year-old child in my truck. I don't want the engine issue to happen while they are in the truck and increases the risk to get into an accident if the engine fails. I have tried to schedule an appointment with my dealership and from the date I received notice on 04/28/2025. They stated I have to call back in two weeks which should be unacceptable because how about if the engine fails within the two weeks and causes even more issues for me and my family. This should be approached much quicker and fix the matter asap.

On April 21, 2025 around 11pm, I was entering my neighborhood, I was slowing to a stop, the truck shut off, shifted to neutral on its own. Clusters were still on though, no error codes other than instruction to turn ignition back on. I tried for over 20 minutes with no luck. I placed the truck in park and shut it off after that I couldn't get it change back to neutral. Was on the phone with onstar and recorded it. Eventually it turned on with check engine light, made it home. On April 22, 2025, I dropped it off at Classic Buick GMC 16835 Katy Fwy, Houston, Texas 77094. Service rep informed me I will require a new engine as there are metal shavings in the oil filter as a result of worn cam shaft bearings. They have had the truck at their shop since the incident.

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.
