What owners wrote
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.
Multiple trips to the dealership and an independent mechanic and the check engine light (cel) comes on with a diagnosis of evaporating system / loose gas cap. Multiple diagnostics fees, a gas tank pressure test and 3 gas caps later and the problem has not been fixed. I noticed a few online forums with several others complaining of the same issue across a wide rage of years and mazda models. There is a design problem with mazada evaporating, fuel and emissions systems. The dealer cannot identify the problem.
