“Engine shuts off while running. Last time on the freeway. My mechanic says the systems reads ok on computer diagnostic, but the fail-safe system definitely shut the engine down due to a possible glitch in the system. Dealers see good readings for throttle system and will not replace a good part. When this happens, car has no power with no warning. It has happened twice and we don't know when it will happen again.”
NHTSA complaint #10311621, filed 2010-02, 78,123 miles“I was driving my 2006 Ford Expedition & the fail safe engine light came on & that stops the gas pedal from working. You then coast over to the side of the road & turn the truck off & restart it like nothing happened. This has happened 2 times about 3 months apart. …”
NHTSA complaint #10396558, filed 2011-04, 82,000 miles“I have this problem where my truck is losing power and then dying while I am driving. This is very dangerous on the roadways. I have a special needs child and grand children that I transport. Ford needs to recall these trucks and fix them.”
NHTSA complaint #10447969, filed 2012-02, 83,000 miles“While in traffic, at least 100 times in the last four years (at variable speeds from 5 to 65 MPH on city streets and freeways) most recently twice in the last week, the rpms drop below 500 and the vehicle dies and engine failsafe mode lights up on the dash. I have to either coast to pull over or dead stop in the middle of the road. I have to turn the vehicle completely off (even though in failsafe mode engine is off, the electronics are still on) and then restart and then it will drive just fine until it happens again. It happens anywhere from once every 6 months to 6 times in 1 week. …”
NHTSA complaint #10971943, filed 2017-04, 117,000 miles“Sparks plugs blew out right at 60,000 miles on 2006 Ford Expedition on our way from maryland to louisiana. Started getting problems in north carolina. After spending 2000.00 for hotel, rental car and possible fix by firestone..it still was not working. Brought to Ford dealership and said it was spark plugs that blew and a common thing for f150s and it would cost over 7,000.00 to fix it and recommended trading it in. So we did cause we had no choice with the truck being in nc.”
