There are 3 owner-reported electrical system complaints for the 2018 Mazda Mazda6in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Was at a drive in window and car turned off and couldn't restart. Windows and lights would work but car wouldn't restart. Could of been driving and would of crashed. Had 3 people family in car. It was 9 pm had to have towed to nearest auto mechanic place 150.00. They are diagnosing and that is 186.00. This is a scary thing and going to BBB and filing a complaint I'm mad as he'll. Have had inspection done on this car 2 months ago and all required services to this car. This was without warning which is horrifying.
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. MAZDA HAS REFUSED TO ADDRESS THIS SITUATION WITHOUT ME PROVIDING THEM WITH AN "INSPECTION REPORT SUPPORTING THE CLAIM A DEFECT WAS PRESENT AND SAID DEFECT CAUSED THE FIRE." AS I WAS ONLY A LESSEE OF THE VEHICLE, I HAVE NO POSSESSION OF THE VEHICLE AND, THEREFORE, I CANNOT ORDER AN INSPECTION ON THE VEHICLE. MAZDA IS ACTING IN BAD-FAITH.
I MADE A STOP AT A TRAFFIC LIGHT AND THE GREEN LIGHT CHANGE I PRESSED THE GAS AND THE MAZDA6 STALLED AND THEN DRAGGED TO TAKE OFF WHICH ALMOST CAUSED AN ACCIDENT.
