So I just hit 160k on my Coyote 14. Only mods are a GT500 axel-back and AM wheels.
Just thought I'd give my experience to date.
Problems so far:
First winter: when the car was cold it shifted like crap (manual). Drained the fluid and put in Royal Purple. Problem solved.
Around 45k miles the diff seal went. Dealer fixed it under warranty.
Right front wheel bearing went out around 120k miles. No big deal. Ordered one from American Muscle, put it in, it failed before I got home, went to Autozone and they actually had one in stock for half the price. 40k miles later it's still good. AM refunded me.
At 155k lost power and threw a code. I was close to home but instead drove it to the dealership. #4 coil pack was bad. They diagnosed and replaced it for $325. Can't complain there. I had thought the worst and it wasn't bad.
Between 120k and 160k I had intermittent dying at idle. Couldn't figure it out. Changed the plugs, cleaned the MAF, checked for vacuum leaks... nothing. Last weekend I was talking with a friend of my wife's who used to work for Ford as a master mechanic and he told me the F150's Coyote's had the same issue from time to time. He said it required the dealership to do a software relearn on the idle position sensor. Googled it figuring there had to be another way and found out that just putting the key in ACC without starting it until all the lights go away allows the position sensor to relearn. Fixed the problem completely! As a bonus my throttle is far more responsive and I'm getting about 2 mpg better gas mileage. Not too bad for 10 seconds of "work".
Of course I have the corrosion on the front lip of the hood. I've sanded it and touched it up but it's still an issue. Doesn't look bad from 10 feet but I know it's there.
The other cosmetic issue is the rear decklid panel. Replaced it with one from AM.
All that is pretty minor when you consider that mechanically I've only spent around $400 for non-maintenance items.
The car has the premium sound system, nav, heated leather seats, etc. Only things it doesn't have are backup camera, cooled seats (is that an option?), and sunroof. It's pretty loaded and a nice place to spend 40-50k miles a year in.
Anyone who sees the car is shocked that it has so many miles. The seats are still in like-new condition, the paint, other than the front corrosion and minor road rash, is still in great shape, and it drives like the day I bought it. So far it has been one of the most reliable cars I've owned. Even still on the original clutch!
Future plans: I'll probably just keep maintaining it as I go for another 2 or 3 years. it seems to be able to take the miles. The engine has every bit as much power as new and the under side shows no rust anywhere. Might lower it but, then again, I might not with the miles I drive.
Eventually I plan on building a Cobra kit car and will likely take the drivetrain out, rebuild it if necessary, and use it in an AC Cobra replica. Who knows how many miles she'll go in the end?
