On the morning of 12/26/24 - I stepped inside my 2023 Subaru Crosstrek and turned on the engine. The vehicle was parked in a commuter parking lot near my home to begin with. When I turned on the vehicle - I noticed a loud roaring sound when the engine turned on which i thought was very strange. Additionally I did NOT have my foot on the gas pedal at all during this time. I proceeded to place the car in drive and all of sudden the car experienced a unintended acceleration straight forward with a sudden burst that i never experienced before. I proceeded to press the brake pedal and tried to turn the steering wheel - but both functions were non-responsive which was incredibly frightening. My car then went straight into a tree with great impact and the vehicle was damaged beyond repair. Also - the vehicle's windshield mounted motion detection camera system (Subaru Eyesight) along with motion detector auto breaking system did not engage before i hit the tree which was very troubling. Thankfully the airbag deployed and other then some medium knee pain i was not injured nor was anyone else injured. A local paramedic truck happen to be onsite at the same time and called local authorities. Overall the malfunctioning of the vehicle is of great concern to me.
