I am reporting two incidents of engine revving that occurred without my foot on the accelerator. In the first incident (Sep 2015), I started the car in the driveway. After a couple seconds, the engine started revving really fast even though my foot was on the brake, not on the accelerator. I remained in park and turned off the ignition. After re-starting the car, everything behaved normally. In the second incident (Dec 6, 2015), I started the car, put it in reverse, and was backing up in a grocery store parking lot. The car suddenly acccelerated backward with the engine revving. I was able to stop it by depressing the brake hard, and then changed the transmission from reverse to drive. The revving stopped and the car drove normally after that. I felt lucky to have stopped the car, however, and it went backwards further and faster than wanted. I checked the floor mats and brake/accelerator area for any objects, and everything was in the correct place. I have not yet had the car evaluated by a mechanic or dealership, but now plan to do that soon.

I'm having with my 09 Cx-9. lightly accelerating around 30-35mph, sometimes the whole car shakes. Doesn't happen all the time. Heavier acceleration or no acceleration fixes the problem but had dobbs check it, but nothing shows up on diagnostics and at first they couldn't get it to repeat. I had to explain that it doesn't happen when you accelerate, but when you sort of hover not giving it gas and not braking and only when at 35-40 mph.

I was referred to contact you regarding unintended acceleration cases with the Mazda Cx-9S. I was a victim of this on January 2, 2013. Upon researching, I was made aware that several other consumers have posted their experience that exactly matched what I experienced. I need to take legal action and warn other innocent drivers before someone is killed or maimed. I have been seeking legal action because Mazda is doing a complete cover up, identical to how Toyota handled their unintentional acceleration cases for many years before people began dying. To date, I have been told by all attorneys I have contacted that had I been killed or maimed, I would have a case. I can not believe in this country that we have to wait until people are maimed or killed when we have plenty of evidence that there is a deadly problem. There must be something we can do before innocent people have to die. Mazda told me (just like all the other victims) there was absolutely nothing wrong with my car, they could not replicate the 60 mph to 100+ mph unintended acceleration during rush hour and that no repairs would be made. Eleven days later, Mazda corporate called to tell me that my parts had been ordered and would be installed that day. I said "what parts??!!!" they told me to call the dealer who was shocked that I knew about the repairs and told me that yes, they were replacing parts but they had nothing to do with the unintended acceleration. Now that the car has been fixed, I'm not able to prove that there was anything wrong with it. Had there been snow or other road conditions, I would have been in a major accident. I have lots of back up documentation I can provide.. I pushed as hard as I could with both feet on the brake (knees locked), the emergency brake on and the car in park. With all of those actions combined, my car still would not stop. No damage-impossible!
