Example complaints

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

“We have noticed the difficulty in depressing the brake pad along with the hissing noise over the past 1 month and it has progressively became stronger. Initially you brush it off thinking you are imagining it. Today on a hill there was an accident so traffic was barely moving, I started to leave more and more distance with the vehicle in front of me as it was becoming increasingly difficult to depress the brakes. …”

“I experienced unexplained sudden acceleration while stopped at a stop light. At the time of the incident there was one car stopped in front of me and one behind me. From the onset of the incident it took just a very few seconds, probably between two and four, for the engine to rev to an extremely high speed. While this was happenings I could feel the vehicle attempting to move forward forcefully while I was applying the brakes very hard. I shifted into neutral and turned off the ignition. I then shifted into park. …”

“I received a recall letter on 6/2016 and called in to schedule or remedy the problem on 07/18/2016, I told the part would be ordered. Called back on 9/20/2016 part was not ordered because person in charge of doing so was fired. They told me that the part would be ordered again and that I would be contacted. Again, I contacted Mazda on 10/2016 and again they told me that the part was inaccurately ordered and that they would call me once it was reordered and received. I have not received a call from Mazda and am very tired of getting the run around. I need to remedy this issue.”

NHTSA complaint #10928552, filed 2016-11
