A 2020 Ford Mustang eco boost premium 2.3L L4 DOHC 16 valve 6-speed manual with push button start convertible top burst into flames on [XXX] at about [XXX]. The entire car and the black box were consumed by flames that spread to my carport, shed and mobile home. From what I read; it might have been designed for a road racing car. I am [XXX] , and requested a small car from Enterprise and this is the only car they had for me. Zero to 60 mph: 4.9–5.7 sec Zero to 100 mph: 13.5–15.5 sec Standing ¼-mile: 13.4–14.3 sec Top speed: 145–155 mph. Why would they have put [XXX] in this car? I drove it as cautiously as I drive my 2011 Taurus. I did nothing to cause this fire. I have reached out to FMC and Enterprise and have finally come to terms that I have to ask for charity to get the home livable. We run a gas generator for one air conditioner, small frig and well pump for water. The roof leaks, the firefighters puled every outlet in the rooms near where the fire entered my home. The electric meter was pulled off my pole as is standard procedure in my county. Now I am begging for a new roof and a new 200 amp box and all new wiring so the county will allow the electric to be connected again. FMC did not design this car well. It caused a disaster for me and my family. I cannot afford a new home, I just want to get this one livable. Entreprises had RIMKUS do a complete investigation which revealed nothing. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I drove my car for 22 miles, parked, and after less than one hour we heard a loud noise from the house and upon checking, we noticed the car was on fire. The fire and smoke was coming from underneath the hood (left side). The car had recent software update and the collision detection and traction control were turned-off and unable to turn it back on. Not sure if the software update had anything to do with it, but thought it would be good to mention that. The fire department came out and said it may have been electrical.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2020 Ford Mustang verdict →
