"...Ford cannot be confident that after many years in service, the speed deactivation switch installed in your vehicle will not leak, posing risk of an underhood fire. Until this repair is performed, a fire could occur at any time. A fire can occur even if the key is not in the ignition, and can occur even if the speed control system is never used. Until your vehicle is repaired, please park your vehicle away from structures to prevent a potential underhood fire from spreading."
