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.

The parking brake failed. Manual transmission. The vehicle was left stationary, parked in a parking lot on only a very slight incline. The parking brake lever was pulled up and engaged, the vehicle not moving as all occupants exited the vehicle and walked away. Upon returning to the parking lot about 15 minutes later the vehicle was found to have rolled back and across the entire parking lot, stopped by its hitting a curb.

The emergency brakes of Mazda 5 do not work. My car slid off while parked and crashed against a mailbox. Both car and mailbox were damaged. Mazda claims it is not responsible as it states in its manual that you need to always leave the car on gear when you park even on a flat landscape. However (1) shouldn't the emergency brake still work and (2) doesn't leaving the car on gear when you park damage quicker the gear box and brakes? other Mazda 5 car owners also complain that they really have to pull hard twice or three times on the emergency brakes so that is stops clicking. This is a safety issue and Mazda 5 cars should be recalled.
