One problem related to check engine light on has been reported for the 2013 Mazda CX9. The most recently reported issues are listed below.
The power steering and power breaking suddenly failed while traveling at about 40mph. The check engine light had gone on a few minutes before the car had this incident. With considerable force on the brake I was able to get the car to the side of the road. It was towed to a garage where they told me a �water line had broke resulting in the engine becoming suddenly filled with coolant�.
