NHTSA Complaint #11716231 — 2020 LINCOLN AVIATOR PHEV

While driving, the vehicle displayed a “Stop Safely Now” warning and immediately began limiting operation. At the same time, steering effort increased significantly, similar to a loss or reduction of power steering assist, making the vehicle difficult to control. I was unable to safely pull over when the warning appeared and was forced to limp the vehicle into a nearby residential street to avoid traffic. After stopping, the vehicle became immobilized and repeatedly engaged the electronic parking brake. The vehicle could not remain in neutral and required roadside assistance. Towing was difficult due to the inability to keep the vehicle in neutral. The vehicle was inspected by a dealer, and diagnostics identified a high-voltage isolation fault (DTC P0AA6) traced to the air conditioning compressor on the hybrid system. The component is currently being replaced. The sudden shutdown combined with increased steering effort and inability to safely pull over created a significant safety risk.
