As I was driving my vehicle around 5 miles per hour on a small street looking for parking, the car had some electrical malfunction that caused it to move forward and hit a parked vehicle, then reversed into another vehicle. The safety of my fiancee, myself and my dog were put at risk as we were jolted back and forth as this happened. The car has been inspected by my insurance company and the mechanic who had to do the repairs. No warning lamps or messages were present prior to the failure.
