I am reporting a serious safety concern involving a 2021 Lincoln Navigator with factory equipment only. After snowfall, during factory remote start, the vehicle produced a hot/burning smell, and I observed visible melting and bubbling of multiple driver-side and passenger side exterior pillars. The vehicle has a factory sunroof and no aftermarket electronics or modifications. The melting appears on the exterior, indicating heat originating from inside the pillar cavities. Due to concern for electrical overheating and fire risk, I discontinued using my remote start. A Lincoln dealership dismissed the concern and incorrectly stated that there is no electrical wiring in the pillars. Lincoln customer care has verbally refused assistance solely due to lack of extended warranty and has declined escalation, despite the reported fire risk. I am concerned this involves water intrusion from the sunroof drainage system contacting powered body or airbag wiring, creating a risk of electrical fire. I am requesting NHTSA review this as a potential safety defect involving electrical overheating and fire risk.
The contact owns a 2021 Lincoln Navigator. The contact stated that while operating the vehicle, the power steering suddenly malfunctioned causing the steering wheel to become very difficult the turn in either direction. Additionally, the instrument panel display became distorted and unreadable, the brake light remained illuminated, and the vehicle would not properly accelerate. The vehicle was taken to the local dealer, but the cause of the failure was not yet determined. The manufacturer was not yet notified of the failure. The failure mileage was 19,000.
