I was already parked in a spot in a public parking lot. I tapped the accelerator pedal to move the car a few inches. The vehicle responded by violently accelerating, hitting a vehicle directly in front of me in another parking space. I applied my brake but the car would not stop. The force of the acceleration pushed the car out of the it's spot and it hit a curb and tree appox 30 ft away. In defensive move I turned my wheels to the right and continue to try and brake. This caused my car to hit the car on the right side of me. Property Damage occured. No injuries. Vehicle defect.Owner report · Forward Collision Avoidance · Jul 2026
First battery drain in car. Bought a new battery and it drained again for the second time. Called Suburu to ask about a parasitic drain from the DCM and they said it was likely that and told me to call Suburu America. Did that but they wanted me to take it to a Suburu dealer to get the problem verified. I don't have the $ to do that. I notice there is a class action in court right now for this exact problem.Owner report · Unknown Or Other · May 2026

Sunroof exploded driving home in 90 degree sunny and clear weather. It sounded like a gun went off right over my head. It scared me so bad I jerked my steering wheel into the other lane. Thank God no one was in that lane. I had to get it replaced at Mid State Glass company. according to what I found on the internet this happens rather frequently. No notification by Subaru that this was even a possibility. I have the receipt the replaced sunroof and photos of the sunroof after it exploded.Owner report · Structure · Sep 2025
