I was parking the car at a low speed (2mph) when it suddenly accelerated with a great speed, jumped the curb in front and moved forward and up a small hill. The car collided with a tree before I was able to stop it. All ADAS features were activated in the car and no alarms sounded prior or during the event, which lasted between 1-2 seconds. The vehicle was inspected by Mazda and deemed safe to continue to operate. The dealer did not find a cause for the malfunction and suggested external influence. The inspection took about 3hrs, which included addressing multiple recalls on the vehicle. At time of incident I have owned the car for about two months and did not experience similar issues, however others did according to my web search. I found reports on popular forums describing sudden acceleration of Mazda CX-90 vehicles.

During normal driving conditions going down a state highway, the vehicle lost speed with adaptive cruise control enabled. Noticing the vehicle was losing speed, I depressed the accelerator pedal. The accelerator pedal was unresponsive and unable to accelerate, I had to maneuver off the highway. Luckily, the car behind my vehicle was far enough behind me and my vehicle was going fast enough that I was able to coast to a safe stop on the side of the highway. A message popped up on the instrument cluster screen informing me to shift the transmission to Park in order to use the accelerator pedal. If this had happened on a road with little to no shoulder, the vehicle would have come to a sudden stop with nowhere to maneuver to. This would have created a dangerous situation for me, and any vehicle directly behind me. …
