One problem related to brake sensor has been reported for the 1997 Ford Expedition. The most recently reported issues are listed below.
This vehicle has had "no brakes" on numerous occasions. When we took it in to our local Ford dealership for the first time on 10-7-98, we were told because they cannot duplicate the problem, we have no problem. When it was taken in on 1-27-99 to our local Ford dealership they called the manufacture this time to find out if any other Expeditions might of had this same sort of problem and was advised "no". They decided because it had the same brake system as another Ford vehicle to change the front sensors. When I went to pick the vehicle up from them, I was told by the service manager that I should drive with the anticipation that the brakes could go out at any given time. They were not sure that this fixed the problem. Well low and behold the brakes went out again, this time a solo accident with this vehicle with "no brakes". We were very lucky no other vehicles were involved as someone would definitely have gotten killed. This vehicle definitely poses a high safety risk to the roads and highways it is driven on.
