2011 Mazda CX-9 Owner Comments

Transfer case - had unusual wear and tear on the transfer case that lead me to lose stearing and driving capability when driving to work. Took my car to car dealer and the transfer case was ground down and the transmission was rusting. Had no water dammage and cost over $4,000. Since have researched and found that many Mazda owners have been experiences issues with their transmisson and transfer case. I believe this should be looked into.

Same issue as everyone else hissing when brakes are compressed -or car is stopped and bad or lagging in braking. My brakes were completely down to the floor and the car kept slowly trying to roll. I had to pump the brakes. Or put the car in park. When I let the brakes go no hissing

CX-9 6-cyl

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.
