NHTSA Complaint #11641299 — 2024 GMC YUKON XL

We are a military family and were stationed in Fort Wainwright, Alaska in 2024. We had orders to move our household and all logistics (ferry tickets, lodging, etc...) were in place to depart on [XXX]. Following our first incident of engine failure with a 2023 Yukon Denali (VIN: [XXX] ) on [XXX], we were forced to trade in the vehicle and purchase a 2024 Yukon Denali XL. On [XXX], my husband and I packed our three daughters and loaded the 2024 Yukon Denali XL (VIN [XXX] ) for a two-week Christmas vacation with our extended families. Just outside Collinsville, Alabama the vehicle automatically shifted into neutral where my husband lost control of the accelerator pedal. Thankfully, we were in the right lane and safely navigated to the shoulder. Had we been in the far-left lane of this busy interstate, our family’s safety would have been at significant risk. Once parked, the vehicle never started again. We waited a few hours for a tow truck and family to collect us and all our belongings. It snowed most of the day and was very cold and while waiting for assistance, our car battery died. The vehicle was towed to Royal GMC in Vestavia Hills, Alabama and diagnosed with engine failure requiring complete engine replacement. General Motors replaced the engine since the vehicle was under warranty; however, after two engine failures I do not trust that this won't happen again. I fear for my family's safety.
