Today while waiting at a stop light the auto start stop engaged. When the light went green I put my foot on the gas and the vehicle stalled. The car was on but not running, several alarms were on the dashboard. I had to put the car in park, turn it off and then restart the car. This is a repeated issue and has been going on at least once a month since we purchased the car in 2021. We've brought it to the dealer and they said there was nothing wrong because there was no OBD code. I have checked myself and I have not found any code. This is extremely unsafe

I brought the car to Subaru but they couldn't find anything wrong. Luckily nobody was behind me when the car stalled.

On Sunday, August 20, 2023 I was pulling into a parking spot in front of an Anytime Fitness at a local strip mall. As I applied the brake, the motor raced and accelerated driving me into a pillar outside of the fitness center. I was in shock, not understanding what had happened. Had I chosen to park one stall to the right, the car would have gone through the window of the business instead of the pillar. Considerable damage was done to the pillar and to my 2021 Subaru Outback, but I was not injured, and no one else was injured. I had the brakes checked at my vehicle service center and was told the brakes were functioning as they should be. The vehicle has not been inspected by the manufacturer, police, insurance representatives or others. No warning was provided by the vehicle. The crash occurred in two seconds.

Infotainment system suddenly shuts down while driving blank screen often triggered while using GPS. Radio will turn on spontaneously at full blast creating a startle effect, often unable to turn off. Had to pull over and turn car off. Daily event has been escalating. Apparently dealerships aware Subaru has been non-responsive. Telling dealerships there is a software fix issue, finally communicating to me there is no current fix. Multiple communications have led to no response. Despite near miss of an accident due to these issues. Almost daily over last 2-3 months
