general problems of the 2006 Ford Expedition

I was coming across arizona, interstae 10 in my 2006 Expedition heading home to san diego when my "engine failsafe mode" indicator came on, the engine warning light was on and shut the engine down. The engine warning light never went off until I took it to a mechanic the following morning. The mechanic stated that I need to have the throttle cleaned out and may need a new sensor for the side of the throttle replaced. I have 59k miles on my vehicle and have the maint. Completed every 4k to 6k and have owned this vehicle from the start. I had 2 miles on the vehicle when we purchased this vehicle in oct 2005. After reading about this problem with other owners I think Ford should be able to repair or replace the problem without charging the customer. This is the second time this has happened to me. Both times we had the cruise control turned on. After stopping in the middle part of arizona on the side of the road, we restarted the motor and made it back home after our vacation.

Engine safe fail mode came on while driving my 2006 Ford Expedition which also lead to the vehicle shutting down in the middle of the highway. The next reading that was connected to this warning was. . . Engine off. . . Low fuel oil pressure. I checked under the hood of the vehicle to see if there was any oil leaks or if the reading was really low and all seen fine. This is a very scary incident because the vehicle just shuts down in the middle of trash which could cause an accident maybe fatal.

I have a 2006 Ford Expedition with approx. 42,000 miles. The incident that occurred with this vehicle, which is dangerous, is when the vehicle's engine failsafe mode engages. I was accelerating from a stop on a two lane road when the engine failsafe mode engaged. When this occurred, I lost throttle control, almost causing another vehicle to strike the rear of my vehicle. The second incident was on Dec. 28, 2009. I was making a left turn onto a sidestreet when the engine failsafe mode occurred again causing me to lose control of the accelerator. I was almost hit broadside when this incident occurred. The only way to regain throttle control is to turn the vehicle off and restart the vehicle. By turning off the vehicle it also resets the engine failsafe mode. Upon checking the engine failsafe mode on the internet, it appears to be a common problem. Someone should make Ford fix this problem before someone gets serious injured or killed.

Three separate times the car shut off in different types of "engine failsafe mode" within the past 7weeks. Engine failsafe mode causes the vehicle to lose all power. Last time this happened on the highway at 60 mph with two small children in the vehicle. Other two times it occurred when slowing down to turn. There is great potential for this to lead to a very dangerous situation. Owner's manual points to cruise control or throttle system stuck although the cruise control was not in use. Each time vehicle restarted with no issues. Dealer reported it was an issue with the throttle body and possibly the throttle getting stuck wide open . No explanation or investigation was done to determine specific issues with the throttle body, except it just needed to be replaced. Repair at this particular dealer runs $800. No diagnostics were done on the throttle position sensor. Although completely unrelated, the dealer offered half off the $600 60k tune-up if I replaced the throttle body. Research indicates this has happened to a lot of 05/06 Expedition vehicles with approx. 50-65k miles, similar to my vehicle. I have yet to repair the vehicle, part is still on it.

This complaint is in reference to our 2006 Ford Expedition. This failure at this time seems to be occurring during normal vehicle operation, at random intervals. The failure is being reported by the obd to be "throttle body stuck wide open" which results in the vehicle entering failsafe mode, which appears to restrict the rpm's of the engine. Upon entering failsafe mode the vehicle tends to stall and subsequently will not start for a short period of time following the failure. This failure occurs weekly at various times of the day. At this time the concern is that if there is any failure on the part of the "failsafe" mode, the vehicle will be unresponsive to the operators throttle control and if the throttle body is in fact stuck wide open the vehicle will proceed to increase speed without regard to the operators controls, rendering the vehicle out of control. After speaking with the service department at our local Ford dealership the recommended course of action is to replace the throttle body as this is a "common occurrence". Searches of this issue online result in many 2006 Expedition owners reporting this issue for vehicles with mileages ranging from 50,000-55,000. The Ford service department stated that there was a service bulletin on this issue but that it did not apply to our VIN. Searching the odi service bulletin database yielded no results regarding this issue.
