One problem related to engine shut off without warning has been reported for the 2021 GMC Yukon. The most recently reported issues are listed below.
With only 52 miles (2-days old), I was driving home when I heard a knock. Then the engine light came on and the vehicle stability control lowered the vehicle and the vehicle shut off. I was left in the middle of traffic unable to move the vehicle to a safe location. Neutral would not work either. When the vehicle was towed to the GMC dealership, they knew exactly what was wrong with the car, broken springs in the engine. Apparently they sent a notice stating that the engine springs were breaking and needed to be replaced. The dealership only offered to replace the 2 broken springs, not all of them since my vehicle was built after the date noted for having issues. They would not provide me with any paperwork about the service. I'm not sure how this company can get away with selling vehicles they know have issues with faulty parts.
