Car was parked and had foot on brake when car suddenly lurched forward and hit a car in front. At first I thought that my foot had slipped off brake pedal and onto accelerator pedal but after reviewing the incident later in the day, I do not believe that my foot slipped. Subaru issued a recall on my vehicle #21V955000 in December 2021 but never notified me directly and I did not learn about this defect until I took the car in for routine maintenance. Was not advised that this recall might be hazardous. It is now been 4 months and Subaru has yet to issue a fix. I am now thinking that what just happened is a result of this defect or some other form of sudden unexpected acceleration and now am afraid to drive the vehicle.
