While slowing to a near-complete stop and preparing to shift into Park at a low-speed private property location, the vehicle suddenly and violently accelerated without any driver input. The operator, a [XXX] experienced driver, had no time to react. The vehicle travelled approximately 200-300 meters uncontrolled, narrowly missed a grounds keeper operating a tractor on the paved road, left the paved road, drove over a fallen log and between trees, and stopped autonomously just before hitting a tree directly ahead. The driver did not brake at any point. The vehicle stopped itself. Physical evidence at the scene shows deep tire marks dug into soft ground consistent with autonomous emergency braking activation directed straight toward the tree. Four witnesses were present including a bystander who nearly was struck by the vehicle. A formal safety case has been opened with the manufacturer's corporate office. Federal safety complaint also filed with Transport Canada. A nearly identical sudden unintended acceleration incident involving a 2023 Porsche Macan while parking is already on record with NHTSA. This appears to represent a pattern on the same platform and warrants formal investigation. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2025 Porsche H2 Macan verdict →
