2025 GMC Sierra 1500

On January 16, 2026, the Office of Defects Investigation (ODI) opened Recall Query RQ26001.  This investigation was opened to assess the remedy effectiveness of Recall 25V-274. ODI has received complaints alleging engine failure in vehicles after the recall remedy had been completed, whether that remedy involved an oil viscosity change or a complete engine replacement. General Motors (GM) issued Recall 25V-274 to address concerns of engine failure in the L87 engines produced between March 1, 2021 and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issue. GM’s recall remedy for Recall 25V-274 consisted of two different repairs, either an oil viscosity change or an engine replacement, based on the results of the remedy inspection procedure. ODI continues to receive reports of engine failures after the completion of the recall remedy. To date, ODI has received 499 complaints alleging post-remedy engine failure in vehicles subject to Recall 25V-274, 473 of which involved an oil viscosity change and 26 a complete engine replacement. Additionally, ODI has received 191 reports of L87 engine failures in engines produced after the production period cited in Recall 25V-274. GM reported receiving 6,953 complaints of post-remedy engine failure. ODI is opening this Engineering Analysisto continue investigating complaints of post-remedy engine failure. ODI is expanding the scope of this Investigation to include engines produced after the production period cited in the recall.

Was about 1 and a half hours into my 8 hour trip home, when I started to hear a clanging sound coming from my engine after I passed a slow moving RV. The truck ran for about 20 additional minutes when it lost power and shut off. Mileage was at a little over 16,000 miles. No warning lamps, messages or other symptoms of the problem prior to the failure. I was fortunate to be pulling into a parking lot when it shut down, GMC roadside assistance had my truck towed to a GMC dealer where it was determined the engine was blown. They replaced the engine.

Vehicle is a 2025 Sierra 1500 Elevation and has made a rattling noise since purchase in May 2025. Radio had electrical issues and required full replacement. Two weeks ago, while driving home on the thruway, the vehicle began to shake violently and display critical warning errors on the infotainment system, locking up and slowing down. Once I pulled over and turned the vehicle off, it would not turn back on. Towed to dealership, where I was told it was a sensor issue that could be fixed the same day. A week later, I was told there was a bent valve that required repair. It has now been two full weeks with no updates on what's wrong with the vehicle or how long it will be under repair, but based on similar complaints, it appears that it will need a new engine since this is a known recurring issue with this model vehicle. This was a massive safety risk to myself and my children if I had not been able to slow down and maneuver the vehicle off the road when it died.

On XXX, my 2025 GMC Sierra 1500 AT4X AEV experienced a catastrophic failure while driving on [XXX] Oh. I had approximately 75000 miles on the vehicle when this occurred. A load explosion from underneath the vehicle and smoke, accompanied with metal thrashing noise and loss of power while in the far right hand lane of the highway. Coming to a stop, I saw fire in the grass shoulder so I inched the vehicle forward away from the fire by a couple hundred or so feet. A passing motorist called the fire department and police who extinguished the fire. I had the truck towed to Knapps Motors Chevy in [XXX]. After looking at the truck, they determined the transfer case siezed and luckily exploded the housing rather than locking up the wheels. If a motorist would have been to my right, they would have been the victim of metal shards and burning oil. This not to diminish the terrible possibility of the wheels locking while driving at 75 miles per hour. After working through GMs customer service line, they have been of no assistance whatsoever. They are pushing the repair on the extended warranty company Portfolio, who is in the process of fixing. I've been without a vehicle for more than a month, as im told the transfer case is a known issue and has an updated part number. The 2026 model year has a federal do not drive recall #26V289 due to an improperly built transfer case missing an oil pickup tube. This has been a terribly unnerving experience and feel this truck should be also involved in the recall.

This is a follow up to my recent safety concern on my 2025 GMC Sierra 1500 with the 6.2 engine. Dropped off my vehicle to our GMC service dealer on 10/22/2026 - Oil change and 15K mile check up was getting close. Mileage at drop off was 14,278 and the engine was still making sounds/noise and getting louder. Asked the service advisor to check for metal in the oil or filter. Based on their service review and advisors response, metal was found in the oil filter and engine is ticking. Service department sent information to GM rep for further actions needed. Dealer rep stated that I need a new engine due to this new found issue. Waiting for response from a GM representative at this time. Truck is in my garage at home. I remain very concerned about driving this vehicle at this time. Just called the dealership as I have not heard of any follow up yet. Call went to voice mail of my service advisor. 6.2 Engine is ticking and metal has been found in the filter. Please add this to my original concern on this VIN #.
