NHTSA Complaint #11716530 — 2023 GMC YUKON XL

On two separate occasions, while driving at approximately 60 mph on New York parkways, my vehicle unexpectedly shifted into neutral and lost power without warning. During the first incident, a message appeared instructing me to “press start to continue.” I was able to restart the vehicle and drive home. Two days later, the same failure occurred again under similar conditions. This time, after pulling over and pressing the start button, the vehicle shut off completely and became totally inoperable. The vehicle had no power and would not restart. At the time of this second incident: - I had my [XXX] child in the vehicle - The outside temperature was approximately 20 degrees - Recent snow made it difficult to pull fully off the parkway - Police assistance was required to ensure our safety - We waited nearly two hours for a tow truck due to the hazardous roadside conditions This situation was frightening, dangerous, and completely unacceptable in a modern vehicle with approximately 24,000 miles. When GMC evaluated the vehicle the following day, I was informed that it requires a full engine replacement. A catastrophic engine failure at this mileage — combined with repeated, sudden loss of power at highway speeds — represents a serious safety defect that substantially impairs the use, value, and safety of the vehicle.
