“The contact owns a 2009 Chevrolet Avalanche. The contact stated that the vehicle was parked on a slight incline when a loud bang was heard and the vehicle began to roll away, in reverse. The rear tail lights were illuminated as the vehicle rolled away before crashing into a body of water. The vehicle was destroyed. The contact's insurance company inspected the vehicle and determined that the failure was either contributed to the park pole or the teeth fracturing in the transmission. The VIN was not available.
