2011 Mazda CX-9 Engine problems

Driving kids to school a few months ago. Car started to smell like burning rubber. I thought it was the garbage truck ahead of us. As we turned the corner 2 blocks later, the car dead stopped and we all went flying forward. It jerked so hard, we are lucky our necks didn't snap. I put the car in park and turned it off. I waited a few minutes as I was too worked up, and started the car again. We got about 50ft before a very loud noise began, almost as if something was dragging underneath. I stopped, and had it towed...

Defective water pump located inside the engine that when failure occurs can cause coolant to leak into engine causing complete engine failure. This is a major safety hazard due to the fact that these cars with defective water pumps can break down with very little warning in the middle of a freeway! I have contacted Mazda who refuses to do anything due to it being outside warranty but will not acknowledge the safety concern sudden engine failure can cause on a perfectly maintained car. In California there is...

The car immediately started to make a rattle noise and smoke or steam came from under the hood. The underside of the car was covered with coolant and what appeared to be oil.

Transfer case - had unusual wear and tear on the transfer case that lead me to lose steering 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 damage and cost over $4,000. Since have researched and found that many mazda owners have been experiences issues with their transmission and transfer case. I believe this should be looked into. *Tr

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

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. *Tr
