The tcm failed on the car and it is a very common thing. The design set the module in a location that overheats and malfunctions when connection is lost with mechanisms that warp under heat, the cost to repair at the dealership was extremely expensive

I have gone to multiple mechanics with no help. My vehicle surges or revs any time the ac is on to the point that the vehicle lunges forward even when my foot is on the brake. This occurs in neutral, drive and park. It specifically occurs when I am slowing down, stopping, or coasting at a low speed. It also jerks when in drive but not applying the gas, then revs with no warning. No check engine or other lights are coming on. I have been on several Mazda forums and this seems to be a recurring issue wth this vehicle. It has caused me to hit a wall (I was slowing down, coming into a parking space) and my neighbors vehicle as I was waiting to turn right out of our condos.

After repeatedly going to various mechanics to get a diagnosis throughout the years, they were all unsuccessful to find any report through the vehicle's computer. However, my car's engine is constantly revved up even when applying the brakes an slowing down causing it to jerk forward. This occurs suddenly and randomly when I am going at speeds below 20 mph including while on idle. If I neither apply the brakes nor the accelerator, it will still drive forward at 3 mph in rhythmic jerky waves. We took the vehicle to the local Mazda dealer for a key replacement when we first purchased it, and I believe we reported the problem there first, but after the ridiculous service we got, I never wanted to return there again. This has been an ongoing issue since the beginning.

I am pressing charges against the Mazda company for failing to correctly diagnose my car when I sent it to be repaired and for causing damage to my engine by telling me it was ready to be driven again. I am also pressing charges against Mazda for putting used tires on my new car, making it unsafe to drive. My story is very long. I have many documents I can submit to be used against them. Please give me the case number and a way I can submit my documents.
