Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“My vehicle's braking system had been functioning normally with the exception of the sound of a hissing when applying the brake when stopped at a red light. I stopped to get gas on may 3rd, 2015 and upon restarting the vehicle, the power assist on my brakes was gone. Upon doing some research, I discovered that Mazda had issued a special service recall that was VIN specific on this exact issue; however, my VIN # was not included therefore I was never notified. …”

“We have had our Mazda CX-9 since 2007. At 58,000 miles we noticed a humming noise. We took the vehicle into the Mazda dealership since it was still under warranty. We got the run around stating it was our tires; however, it turned out the front wheel bearings were bad. They replaced the bearings and one year later we are having to replace the rear bearings. Through research we are finding that Mazda has a service bulletin issued 2/1/2008 about the rear bearings. …”

“On friday, october 18th 2013 I was involved in a near accident on my way home from work on interstate 99 off the 17th street exit near altoona pa. The brake system failed as I tried to come to a stop on the exit ramp. I placed my foot on the brake pedal and noticed I was not stopping. I could hear a hissing/air sound when I pressed down on the brake pedal. I had to pump the brakes, gear the car down in manual, and swerve off the road to avoid crashing into the car that was stopped in front of me. …”

“For a couple of weeks, I've been noticing a hissing sound coming from my brakes on my 2007 Mazda CX-9. I didn't think much of it at first until tonight. My sister was driving the car and said it was extremely hard to brake the car. I wanted to see what she was talking about, so I got in the car and as soon as I placed my foot on the pedal to start the car and put it into reverse to back out of the driveway, the hissing sound was very loud and much more noticeable than before. Once the car was in gear, the breaks were kind of stuck on. …”

“My daughters 2007 mazdacx-9, right rear wheel bearing has been replaced 3 times in the first 46,000 miles of ownership. The vehicle was purchased new and parts have been replaced at no cost. Have been made aware there is a service bulletin from the factory stating rear bearing problem is due to an improperly installed or misshapen ABS sensor. Bulletin states will only be replaced free during warranty. This problem could have serious ramifications to occupants if not permanently repaired because ABS sensor is involved.”
