NHTSA Complaint #11659663 — 2023 GMC YUKON XL

While driving at approximately 30 mph in moderate traffic on the interstate during a return leg of a 370-mile trip, my vehicle unexpectedly shifted into neutral and became unresponsive. The dashboard displayed the warning message: "condition not correct for shift," and despite repeated attempts to restart the engine, the vehicle would not engage. Although the electrical system remained active, I had no propulsion. Critically, the vehicle became immobilized in a **very dangerous curve on the interstate**, presenting an extreme safety risk to myself and others. The car could not be manually shifted into neutral for towing, prompting Illinois Department of Transportation (IDOT) to declare the location unsafe. I was stranded there for over three hours, after dark, in a vulnerable and exposed position. During the forced tow process, two rear tires were destroyed and the two front tires sustained major damage. In the days leading up to this incident, the vehicle had also shown signs of malfunction, such as delayed acceleration from a stop and occasional lurching forward — symptoms consistent with the defect described in the recall.
