On 1/16/2026, while operating my 2017 Ford C-Max Hybrid in the Bay Area, the vehicle displayed a low tire pressure warning. Shortly thereafter, the vehicle experienced a rapid mechanical or electrical failure that required me to safely pull over and exit the vehicle. Upon exiting, I observed smoke followed by open flames originating from the vehicle. Emergency services were contacted immediately, and the fire department responded and extinguished the fire. The vehicle sustained catastrophic damage and was declared a total loss. The vehicle was towed to a storage facility following the incident. No injuries were sustained. The vehicle had not undergone any recent mechanical repairs or modifications beyond routine maintenance, including an oil change approximately two weeks prior to the incident and a state smog inspection approximately one week prior. The vehicle had been operating normally prior to the warning and failure. All physical documentation stored within the vehicle, including the title, registration, and passport, was destroyed in the fire. Photographic and video documentation of the incident and damage, along with contemporaneous incident records, are available upon request.

Rear back-up camera does not display on dashboard console screen when air temperature is cold, i.e. below about 45º, and will only turn back on when the car has sufficiently warmed up after driving some distance. This has been happening for at least two years. When the camera is not working, there is a blind spot directly behind the car. The rear of the car proximity warning signal still works, but the screen remains black. I brought this problem to the attention of the dealership service manager, who told me he could not find anything obviously wrong.

Ford Dealer Service recommends I replace lug nuts. I have 35th miles. That they are expanding and Ford cannot assure they or other repair shops will be able to remove lug nuts for repairs or replacements such as brakes, tires, etc. I read many complaints online about this problem, that the lug nut can break causing other lug nuts to break under pressure, that cause tire to fall off. They do not replace under warranty and do not discount parts. I call upon the federal safety agency to have Ford recall these affected cars for replacement lug nuts. Thank you
