What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
I was on freeway when some warning start showing on dashboard ( enging, track control system, battery) then my steering wheel was hard that I couldn’t manubrio i hit a curb that was on the entrance and my car start spinning in circles till i hit the hill on side road.
The contact stated that while driving about 20 mph in the snow, the brake pedal was depressed and the vehicle lost all powers as the steering failed. The vehicle slide and rear-end the vehicle in front. There were no warning lights illuminated. The passenger side door air bag was the only air bag that deployed.
To my surprise the airbags did not deploy (particularly my side airbags). Later I learned that mazda (manufacture) reported a recall for my vehicle relating to a potential malfunction of side airbags.
Was in an accident which resulted in a lockup of vehicle and side collision with battery failure
Various software control features transiently stop working. The navigation system has failed to come on several times. The key fob stops working and then works again.the problems are always transient and then start working again.
Tires should not blowout that quickly with proper care of the vehicle. The tire tread wore too fast.
Then the car suddenly surged forward and went over the curb on to the other side. Thankfully there was no other vehicle or person on the other side. I was holding tight the steering wheel. My husband pulled the electronic parking break button and the car finally came to a stop.
No warning lights illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed that the clutch disc kit had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was filed. The failure mileage was approximately 125,166.
