While in the carpool lane of freeway this truck without warning shut down power/speed and turned off with a wrench light coming on. the second time it did this on the freeway in the middle lane the throttle body was replaced. on 05/19/2011 it did it again in the fast lane of the freeway and went to two dealers who said they can't "replicate" the problem so they can't just try fixing everything it could be. the dealer refuses to stand behind the product he sold. he said," he couldn't help that ford made a bad car". it is sitting at the dealers service area because i feel it would be negligent of me to put this truck on the road. why it hasn't caused an accident i don't know.
