I was pulling into a parking space very slowly when the car went into overdrive and suddenly accelerated at a high speed. It plunged down a slight decline and hit a large tree. My airbag failed to deploy although I was thrown violently forward, and the car sustained severe front end damage. The car is considered a total loss and I spent a day at a hospital emergency room. The sudden unexpected acceleration and the lack of airbag inflation is going to be assessed by Subaru on 10/24/23. I understand that there are two class action lawsuits against Subaru (in NJ & CA) for this same unanticipated acceleration issue.
