I have a Mazda 2012 that spontaneously stalls while decelerating. It also stalls predictably on an incline. Mazda corporation has stated "the stalling on an incline is a characteristic of all Cx-9 models" and are not willing to fix it. They have informed me that stalling while decelerating in my car has not been able to be recreated by their tech so they are doing nothing about it. I have been in two near miss accidents. The car loses power steering and braking and the driver has little to no control when it stalls. Please watch this video of a brand new (loaner from the dealer while they looked at my 2012 Cx-9) 2013 Cx-9 (125 miles on it). This is the "characteristic" I am referring to, please advise future buyers of this very unsafe "characteristic". when it stalls in my driveway, I cannot brake "sharply" or effectively enough to stop the car from drifting into the road. youtu.be/pbzhvieihkc.

I had an incident yesterday resulting in a minor collision. My accelerator stuck, my engine kept revving, and I could not stop. I kept applying the brakes but it felt as if everything locked up. I rearended the person in front of me no damage to their car and only minor to mine. I am now afraid to drive the vehicle. My husband contacted the dealership and they are waiting to hear back from Mazda corporate.
