Vehicle was being parked in garage when it accelerated in reverse, on it's own, very quickly. Fortunately I was able to avoid colliding with any thing behind me by braking in time. I then shifted into drive when vehicle accelerated forward, on it's own again, very quickly. I was not able to brake before vehicle crashed into concrete garage wall, severely damaging front end. Vehicle is still under warranty, and I intend to have dealership haul it in for repairs. I have found other drivers complain on the Internet of experiencing the exact same issue as I described above. This model, Chevrolet, Equinox, 2025 is not safe to drive!
