A couple of problems.
So for nearly the whole time I have had this truck, I would periodically get this buzzing noise from the engine bay, roughly 1 minute after shut down. It's very loud, and gradually tappers off until it's gone. I took it to one dealer, who said they had a call into Ford, but in the mean time, did not know what it was or how to fix it. They said it was no danger to the truck, and to keep driving it.
Recently, on an unrelated problem, my truck randomly tells me to pull over safely, and all my power is cut. No matter how much the pedal was pressed, I had nothing. When I finally got to a place with a wide enough shoulder I was doing about 20mph when all the sudden the truck gained all power back, and drove normally (except with a check engine light)
Drove straight to the dealer (only a few miles away)
They found that there was some type of throttle sensor code, and have decided to replace the entire throttle body along with the throttle position sensor, and also the pedal position sensor.
I decided while it was there, I'd have them look into the buzzing, which they did. I had figured it was something to do with the turbo/waste gate/ect, and it did in fact end up being the waste gate solenoid (they think).
Parts are on order for everything. Turns out the waste gate solenoid is on back order, so who knows how long that will take.
My seat belt buckles also squeak REALLY bad, when buckled with a passenger. Of course, they can't re-produce the squeaking lol. Anyone else have this happen?
Doing the 15k mile service while it's in also.
