I was driving my 2026 Mazda CX-30 in a parking lot and was pulling into a parking space at a very low speed. I lightly pressed the accelerator to move the car forward, but the car suddenly surged forward much faster than I intended or expected based on how lightly I had pressed the pedal. The sudden acceleration resulted in a collision and property damage. There were no warning lights, warning messages, or other dashboard alerts before or at the time of the incident. I do not know what specifically caused the car to accelerate this way. I am concerned that there may have been an issue with the accelerator/throttle response, engine controls, transmission, PCM, or another part of the powertrain. The vehicle has not yet been inspected by Mazda or an independent engineer specifically for this issue, so the cause has not been determined. It is currently as a collision center. Before the accident, I had also noticed that the vehicle's acceleration and pickup sometimes did not feel normal, although there were no warning lights or messages indicating a problem. I am reporting this because the car's unexpected acceleration at such a low speed created a serious safety concern. I would like the incident and vehicle to be investigated to determine whether a defect or malfunction contributed to the sudden acceleration. The vehicle is available for inspection.
