What owners wrote

My mazda6 spontaneously caught on fire while it was parked on a street and completely burned down. The fault/problem cause is unknown at this time but I suspect there was wiring/electrical fault and manufacturing and design defect. Both the sheriff's department and fire department were involved in assisting me in this incident. I am still waiting for reports from law enforcement/first responders.

After turning the engine off and back on the vehicle operated as normal but later while driving approximately 65 MPH the failure had reoccurred while attempting the pass a semi-truck on the freeway.
