Owner report 11560030 · 2023-12-14 (December 14, 2023)
I submitted this form earlier, but I’m unsure whether it went through. If this is a duplicate, please disregard. An incident of sudden, unintended acceleration occurred while pulling into a gravel parking area on a hillside at dusk. While turning, the vehicle suddenly lunged forward and struck a tree stump. It would have been avoided without the sudden acceleration. The driver slammed on the brakes, and the vehicle came to rest right at the edge of a downward slope. Five seconds earlier, and a family member, who had come out of the house to sh…

This caused the vehicle to strike a curb, damaging both passenger-side wheels and the front tire. There were no warning lights or indicators, and road and weather conditions were normal. The uncommanded steering input appeared to c…

I held the brake pedal at full pressure continuously. I never touched the accelerator. The vehicle came to what appeared to be a complete stop then continued to advance and made physical contact with the container despite my maintained maximum brake input. The vehicle's own ECU-recorded Freeze Frame Data (retrieved by an authorized To…
