Hi Everyone!
I have a 2012 f150 3.5L with roughly 75,000 miles on it.
The other day while I was driving in Michigan, I heard a rumble noise coming from under the engine.
I notice the noise happens when decelerating from 2,000 RPMS. The noise happens for a second and then goes away.

Took it it to the dealer to see if they could figure it out and they said my turbos were going out.
From what I've read, the Turbos should be good for 150,000 miles.

Does anyone one else have this noise issue?

 

Well, I feel for ya......but this is nothing new (although I have been chastised for saying this years ago).
Yes the tech is great but…..the 70’s & 80’s were demonstrative of the numerous issues including finding a "Tech" who actually understands & can diagnose the system without causing further damage....this is a challenge with the engines we currently have.

I would wager the reliability on the 5.0 any day compared to the much more complicated Ecoboost. There are issues also with direct injection that the Europeans have never been able to address…carbon build-up....although they have improved greatly....but turbo coking has and always will be an issue for any high boost turbo engine driven in environments other than the freeway and leads to turbo impellor failure in a very short duration.

Considering the high boost levels (12 psi) as compared to typical aftermarket systems (6-8 psi), this leaves a lot of reliance on the systems to work correctly…as this makes the engine much less forgiving especially with engine mis-fires, etc. which are very prone to burning a hole through a piston (if you are lucky) or even worse, causing substantial catastrophic engine failure (rod through the block)

These (IMHO) are also soon to be the newest "Disposible engine" because the troubleshooting &/or repairs will exceed the value of the vehicle real fast!
And it’s been showing for a long, long, time………..
