NHTSA Complaint #11716014 — 2025 MAZDA CX-70

On the morning of January 28, 2026 I arrived to work and came to a complete stop in my works parking garage. I used my key card to raise the gate. Once the gate was fully raised I pressed the accelerator to drive up the ramp. Shortly after accelerating, my engine revved really loud and high rate, then my car automatically increased speed. I immediately pressed the brake pedal but it didn’t stop. It continued accelerating at a speed not controlled by me with my brakes not engaging even though I was pressing the brake as hard as could. I estimate I travel about 100’ with no control of the gas or brake. It lasted about 15-20 seconds. If a car were in front of me at that time, I would have crashed into them because I could not stop the car. I immediately called Davis Moore Mazda. I had the vehicle towed there because I didn’t feel safe driving it. Information from my cars computer program was sent to Mazda. Mazda didn’t see any issues and their diagnosis was a foot was likely on the accelerator causing the acceleration. The general manager called me to discuss. He said the only thing that registered was acceleration. I asked does the computer show my attempt to brake (stop) the car. His response was the computer wouldn’t read that because that was a normal driving process that wouldn’t be recorded. I asked why the acceleration would trigger an alert in the computer, since acceleration is also a normal driving process. He then said the computer picked it up because it accelerated quickly. There were no warnings present prior to this issue.
