Engine squeak noise when hitting gas pedal

GGecko311 · Aug 11, 2022

I've noticed a slight "squeak" noise when hitting the throttle. It just started doing this today.

I was recording a video of it idling and it also did it randomly. Does anyone know if this is normal or have had similar experiences? I wasn't sure if this was related to the turbos, or the maybe the throttle/intake. I recorded two short video clips, and in the second clip it does it randomly while I'm standing in front of the truck. (unless this is a normal sound, and I am just now noticing it)

Thanks in advance.

I have this same issue but only with the brake pedal on minor depressions. Doesn't sound like it's from the engine but from the cabin near the pedals. Never bothered me enough to pursue further investigation. Might be the pedal mechanism requires a bit of greasing?

UPDATE - So the squeak noise got loud to the point where I had to turn up the music to drown it out.

I took it to the dealership and turns out it was the bushing on the waste-gate on the turbo. The tech sprayed it and worked it clear and no longer squeaks.

Thanks for posting the fix!

Ok so the noise is back. When I first start the vehicle and the engine revs down to normal RPM's, it makes a series of the same squeaks that lasts maybe 10 seconds then goes away. It's the same sound that happens when I hit the gas pedal slightly. Dealership said they cannot find anything wrong with it.

That is 1 annoying sound & I have no clue what that could be! I've owned my EXPY for over 2 years & had a turbo replaced for the waste gate rattle issue. Never heard these 4thGens make that noise. Looking forward to reading what you find out on this.
