2026 GMC YUKON XL Engine Problems

On [XXX], I was driving on the highway with my family in the vehicle and the check engine light came on, then it started running roughly. I headed off the highway on an exit ramp and the engine died about halfway down the ramp. It wouldn't restart after that. This happened about an hour away from my house in Painesville, OH. I live in Erie, PA. I had to tow it to the nearest GMC dealer. They've since concluded that the engine failed and have ordered a replacement engine from GMC. The yukon only had about 4,900 miles on it. GMC has claimed that their engine problems were fixed for the 2025 and 2026 model years, or else I would not have purchased this vehicle. Obviously there are still major issues and the 2026 6.2L engines need to be recalled. I understand that there is an ongoing investigation into these...

Purchased brand new vehicle 2026 XL Denali, hadn’t even had my first oil change, and had a complete engine failure in the middle of the road. Prior to engine failure, car ran fine without an issue - so failure came out of nowhere. Towed, where GMC and dealer determined entire engine needed to be replaced. GMC did cover and dealer did install a new engine. However: 1. I was out of a vehicle for almost a month. 2. I have incurred a depreciation cost of 10-15% on my vehicle due to this problem. 3. I have lost confidence in my brand new vehicle, as GMC has not fixed the reoccurring engine problems from previous years - despite promises to the contrary.

Vehicle has 2200 miles, equipped with the Diesel engine and failed at a red light. GM has to install a new engine.

Vehicle engine stopped working at 5200 miles. Was driving on highway and immediately stopped. Vehicle would not start. Towed to dealership and next day dealer confirmed that the engine needed to be replaced.

The contact owns a 2026 GMC Yukon XL. The contact stated that while starting the vehicle, there was an abnormal sound coming from the engine. The abnormal sound disappeared after the engine had warmed up. No warning lights were illuminated. The vehicle was towed to the dealer, where it was diagnosed and determined that the engine had failed and needed to be replaced. The vehicle remained at the dealer unrepaired. The manufacturer was not notified of the failure. The failure mileage was approximately 3,500.
