There is no warning - my Ford Expedition just goes into engine fail safe mode and shuts off - no ability to steer, drive etc. Was traveling on highway at highway speeds (55+ mph) when this happened. The engine fail safe had come on before but was a bit scary upon driving at a speed. The dealership states that the throttle body needs to be replaced. My vehicle only has 55000 miles on it - and from reading other forums I see that this is a problem with a lot of Ford Expedition. It is in the shop now (at a cost of $700) being fixed, I am going to request to have the old parts saved so I can keep for future reference. I believe this is a major defect that needs to be fixed as it will cause a death one day soon - as the vehicle shuts off during driving.

Purchased vehicle in January 2006, brand new from the dealer. Shortly thereafter, the back window was leaking. Had the back window repaired, still leaks. The seal on both the driver and passenger's front windows were missing. Took the vehicle back 3 times before this was fixed. After that, the engine began making a loud grinding noise. Vehicle has been back in the shop at least 3 times, one time they kept it for a week, claim they can not duplicate. They then decided it was the A/C compressor and we should have the A/C off when starting the vehicle. Tried it, does not work. Now that the vehicle is out of warranty, it is making the loud grinding noise even more. At one point, we were told by a salesman that we should just call roadside assistance if we break down while on vacation. Just what we wanted was to have our vacation ruined by a Ford screw up. The dealer won't acknowledge that there is a problem and won't fix it. On top of that the dvd entertainment system that came with the vehicle won't stay closed, the cover over the motor for the third seat has come detached and doesn't fold up right and the air conditioner is warm when sitting still. All problems that a major corporation should not have on a vehicle that has been on the market for several years. Would really like all the problems completely fixed or a replacement. Driver's side airbag did not deploy when had very hard frontal impact either.
