On XXX, I experienced a serious safety incident involving my 2019 Ford Expedition, VIN [XXX]. My family and I were parked at a Lowe’s with the vehicle running but completely stationary. I was in the driver’s seat wearing my seat belt. Without any collision or impact, there was a sudden loud pop and the driver’s seat belt forcefully tightened around my chest. It was violent enough that I initially thought another vehicle had struck us from behind. Immediately afterward, smoke/haze appeared inside the cabin and moved toward the windows, accompanied by a strong chemical/burnt odor. My family and I immediately exited the vehicle and remained outside for approximately 30–40 minutes before entering again. Lowe’s may have surveillance footage confirming that the vehicle was stationary, no collision occurred, and we exited immediately afterward. The driver’s seat belt has not functioned normally since the incident. The vehicle had also displayed an airbag/SRS warning light prior to this event. I have photographs documenting the condition of the seat belt immediately afterward. I contacted Ford Customer Relations. The first representative requested my Social Security number, which I declined to provide, and then requested an account number I did not have. The interaction became hostile, and he told me I was “terrible.” When I asked to speak with a supervisor because of his behavior, the call was disconnected. I called again and spoke with a more courteous representative. She initi
