What component or system failed or malfunctioned, and is it available for inspection upon request" - Immobiliser System. Yes, available. May be repaired by local mechanic unless I learn from you to defer such repair. How was your safety or the safety of others put at risk" - The inappropriate activation of the immobilizer system (at least I think that's what happened) caused the vehicle immediately to become unnamageable. All lights off, motor stopped, no power brakes pr power steering. No way to give warning to other drivers. Has the problem been reproduced or confirmed by a dealer or independent service center" - The identical behavior has occurred about 6 times, once on busy US 101 through downtown Oakland, CA during rush hour. The car will be towed to a mechanic's shop later today. I have no history with this mechanic's shop. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? - No. It is my inference that the immobilizer system activated while at speed due to description in the owner's manual of the appropriate behavior of the immobilizer. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear" - No. The first appearance of the "green key" light preceded the entire shutdown by only a few seconds.
