“What component or system failed or malfunctioned, and is it available for inspection upon request? The engine/transmission and the vehicle is available for inspection upon request. How was your safety or the safety of others put at risk? While driving the vehicle at the rate of 55-60 mph, the vehicle came to a complete/instant stop without warning — potential causing harm or even death to the occupants of the associated vehicle, and it adversely affected my ability to safely control the vehicle. Also, as the incident was occurring, my drivers seatbelt became very, very tight. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, but this is the second occurrence of this same incident within the past 30 days.”
