The vehicle exhibits dangerous electronic malfunctions. A licensed technician (MV-113255) has confirmed a sporadic unintended acceleration defect where the cruise control 'decrease' button causes the vehicle to increase speed. Additionally, the vehicle repeatedly enters 'Limp Mode' in active traffic, causing a violent jerk and a total loss of acceleration while displaying a 'Smart City Brake Support' (SCBS) failure on the dashboard. An independent inspection also documented gross mechanical neglect, including loose battery terminals and a loose transmission bellhousing bolt, which may contribute to these intermittent electrical/safety failures.

What owners say
I pulled into my parking space in front of garage door, I came to a complete stop and positively without any doubt, put my foot on the brake. As I shifted to park, all of a sudden engine loudly revved up and car suddenly and quickly accelerated through garage door. I want to make it perfectly clear, I DID NOT HAVE MY FOOT ACCIDENTLY ON THE ACCELERATOR WHEN CAR SUDDENLY ACCELERATED. Mazda checked the car and said nothing was wrong with the car. This has happened to many other people with Mazda and other makes and people are told too many times that there is nothing wrong the car when it clearly is not human error.
The car had a (SUA) Sudden Unintended Acceleration malfunction. No, the car was totaled and towed away. My safety was put at risk as I was slowly pulling into a parking spot, eased my foot onto the brake and this malfunction caused my car to involuntarily jolt into a rampant high speed. It jumped a curb and crashed into a tree. My brake was useless in stopping this runaway vehicle. The only thing that stopped it was that tree! The airbag deployed and I was badly bruised from the airbag. Fortunately, there were no pedestrians or other cars near mine. There were no warning lights or messages before, during or after the accident. It happened so quickly because the tree was only a few feet in front of my car.

I was about to park the car in a parking spot in a mall. It was crawling speed and almost about to stop. Then the car suddenly surged forward and went over the curb on to the other side. Thankfully there was no other vehicle or person on the other side. I was holding tight the steering wheel. My husband pulled the electronic parking break button and the car finally came to a stop. Tires were burst on running over and there was damage to front left side of car. I believe this could be an issue of unintended acceleration.
