Driving to work via freeway, had just reached the bottom of a freeway off-ramp, at a stoplight. Light turned green, had just started to go and the "fail safe engine mode" light on my 2006 Ford Expedition came on the dashboard, within 5 seconds the car turned off on its own, like taking the key out of the ignition. Had it towed to a Ford dealership, they ran diagnostics, said the throttle body assembly needed replacing. I looked on the internet, googling "fail safe engine mode" and "Ford" and found this to be a common problem. Asked why it's not a recall item or has a technical bulletin with so many cases of it, plus it's very dangerous. Many in their internet postings said the problem comes back. Dealership said to contact Ford corporate, opened a cudl case for me to request reimbursement. Wrote a letter to Ford corporate, included internet links to all the postings of other people having the same problem, asked for $480.35 reimbursement, also asked what they are doing about this dangerous situation with the throttle body assembly. Ford corporate send me a letter back, simply said I'm past warranty and unable to provide reimbursement. They did not reply regarding my question about what's being done about this dangerous problem.
