I am the 2nd owner of this vehicle. Had problem w/ drivers seat & mirror fuse blowing out since I purchased truck in August 2011. Some time in 2012 I started having additional problems w/ my truck like radio &/or heating/air not coming on when started. Check engine light going on & off & back windshield wiper stopped working. Then it was the vehicle was dying quickly by leaving the radio on for 10 min after vehicle was turned off. We replaced the battery & terminals that connect at the positive & negative. We had plenty of other issues like the entire brake lines needing replacing due to rusting. There is now rusting on other parts of the truck. Blew fuse to air conditioner 2x. Things seem to be ok after battery was replaced until the truck shut off several times while driving it over the past year. Sometimes if you waited 5-10 minutes it would restart. Vehicle has been in shop & nothing comes back on diagnostic test. We have had the alternator & fuel pump tested. The cables to the battery were just found rotted & replaced but something is still killing my battery. The fuse box has been making loud click noises when the truck struggles to start. Today it wouldn't start again until jumped & now the radio wouldn't go on. At the shop again & the mechanic is stumped but working on it! from research it seems to be either a fuel pump relay that is apparently sodder into the fuse box & almost impossible to replace w/ replacing the whole box or it is the fuse box itself. I am also seeing claims of water leaking down windshield & getting into fuse box. All I know is Ford should acknowledge & recall before someone gets killed! my children were in the car several times now when it staled while I was driving or stuck in parking lot & even a severe thunderstorm when it won't start. And now I'm reading the fuse box has caught fire in some of these cars! I rely on this vehicle!.
After owning the vehicle for about 3 months the battery went dead, I put a new battery in it and it worked fine for about 2 weeks then it was dead again. I hooked it to a diagnostic machine and no codes. I then replaced the alternator and now there is a code but since the 1st incident I had to disconnect the battery every time I turn the engine off or after 4 to 8 hours the battery is dead again. I haven't had the codes check yet but I will soon.
