CX-9 6-cyl

  • 30,345 miles
While driving on interstate 77, North bound, at 55mph, other motorists informed me that my car was on fire underneath. There were no dashboard warning lights or signals that came on it light up as a warning sign. I pulled over to the side of the road, the fire department and sheriff's office put out the fire and the car was towed. The car is quite new and with very low mileage. Well maintained car. No recent work other than regular oil change. Mazda denies any problems with this car.
