“Charge system service now” came on the dash, battery lost power after about 10 seconds, screen went black, dash went black, car locked up, opened the hood and the engine was on fire, called 911 who came quickly and put the fire out without the entire car burning, insurance later total losses the car. I don’t know if it was the battery or the engine responsible for the failure, because the flames were on the engine and not the battery, but the incident was triggered by a battery warning. I was on the interstate driving 60mph when the car shut off and everything including my headlights and even hazard lights went black. Not only could I have been struck by a car on the interstate, I could have died in a car fire. Because the car locked up, I couldn’t open the trunk or use any electronics. The door could have just as easily locked and trapped us inside a burning car. The car is on a salvage yard, no attempt to replicate has been made. Progressive insurance, and Columbia fire inspected it and found that it was undetermined. “Charge service system now” was the only warning before the infotainment screen shut down to reduce battery usage. Every light on the dash flashed right before everything on the dash went black and power was lost to the entire vehicle.
The most common engine failure issues are associated with the 2.3L EcoBoost engine, which is prone to coolant leaks causing significant damage to the engine.
