Since I purchased in 2009, engine kills anytime, mostly when gas pedal not pressed. Pulling out of parking lots, sitting at red lights, or letting off gas on interstate, engine just kills. Sometimes feels like a jolt. I have to put the shift in neutral and restart the engine. Records of all visits for the problem at dealership. Never could solve problem, but too unsafe to donate to my grandson. If something were to happen to him because of a defect that was never found, I don't know what I'd do. Cannot check transmission fluid level. Sealed. I do have some fluid stains on my driveway. For years I've reported to the dealership and specified the concern for safety but to no avail. It kills anytime. May not die for a week, or tomorrow, or even a month. No particular pattern. Feels like a transmission problem. If I'm sitting in a parking lot with motor running, sometimes it just kills. It's the shifting to neutral while driving on highways and streets to restart while moving I'm worried about. I've had several mechanics claim they fixed it but to no avail. Please give me some direction. All the shops I've gone to are reputable businesses. One mechanic said the electronic brain (computer box) might be causing and said to send it to Mercury for recalculation. I don't know about that. Most of the read outs are epa related.

**************************engine will shutoff without warning********************** it has happened with various levels of gas, various weather conditions, and both while stopped and moving. The "check fuel filler inlet" light will come on. Sometimes, the check engine light will remain on, but will clear within the next startup or two. Car has been at dealers at least 4 times for issue. Engine throttle body and crankshaft sensors have been replaced. In the beginning, the vehicle would do this once or twice, then run perfectly for months at a time. Each time it is "fixed" by dealer, who claims they cannot replicate the problem. Lately it will stall 4-6 times within a 30 minute period. Last month, I was able to read code 2107. Today, it stalled again 6 times, no check engine light remains, no code to be read. When car is running normally, it sometimes hiccups and seems to run rough.

Engine will not turn over. All electronics work. Keep turning ignition key on and off sometimes it will start in a few minutes other times it has to sit for a half hour or more. Dome light will come on for no reason. After reading others having same issues, I turned on easy access and slightly turned ignition key and sure enough the seat went back and dome light came on. This vehicle has been to a Ford dealer numerous times, once towed, and they can't seem to duplicate the problem. Thanks to this website I now have more information and hopefully will be able to get this on going issue fixed. The easy access is always turned off. The no crank no start is the big problem because I can't go anywhere for just a half hour and be confident it will start.

I have 2 broken bolts on my rt side exhaust manifold and once and a while can smell exhaust fumes in the truck. I've taken it to five separate mechanics for diagnostics the repairs are very expensive and everyone said there should be a recall for this. After a little research there are hundreds if not thousands with this same problem I have grandchildren who have to drive in this truck every day and are subject to dangerous fumes why !!!!!!!!! hasn't Ford done anything about this. I called Ford tell them what the problem is and get nowhere there exact word are ( there isn't enough complaints about this problem ) bs !! look on the internet and you'll see NHTSA needs to help people with this now before it's to late.

Vehicle is missing, now shaking. Need spark plug replaced but is stuck. Needed special tool/equipment to get out. Will be very costly. I shouldn't have to have this problem since I only purchased it almost 2 yrs ago. I am really contemplating suing!!
