MY 2020 MAZDA CX-5 WAS 2 DAYS OLD AND THE BATTERY WAS COMPLETELY DRAINED AND HAD TO BE TOWED TO THE DEALER. I PICKED IT UP AND THEY DID NOTHING TO THE BATTERY. THEY TOLD ME NOTHING WAS WRONG AND THEY REPLACED THE KEY FOB BATTERY. TWO MORE DAYS AFTER THAT I PARKED IT IN MY GARAGE AND PUSHED THE BUTTON TO TURN IT OFF. APPARENTLY IT DID NOT TURN OFF AND COME MORNING, I HAD SIGNIFICANT CARBON MONOXIDE POISONING AND WAS HOSPITALIZED FOR 4 NIGHTS. MY CAR WOULD NOT START AGAIN AND THE ODD THING WAS THAT THE BATTERY WAS DRAINED AGAIN AND THERE WAS STILL GAS IN IT. MY LOCAL MAZDA DEALER REFUSES TO HELP ME AND I AM TRYING TO CONTACT MAZDA'S MAIN NUMBER.

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
