GEN 2 Noise and vibration when engine is cold

[Messiah62]

Debating with myself on whether I should take my 2018 Raptor into Ford to get an issue checked out. I am debating due to the service person may just say I don't see anything or hear anything so it must not be an issue...

When I start my truck in the morning on a cold morning there seems to be a low shuttering sound and vibration when braking as I come to a stop or slow down. It seems to go away after my engine has warmed up. The brake pedal will have a slight vibration, and it sounds like its coming from the front left of the car. I don't know for sure that it is due to the cold, but in the afternoon it doesn't seem to occur.

Has any one else seen or had this issue?

For me, this was IWE issues. It took nearly 5 months to get the dealer to fix. They replaced the IWE lines, check valves, and hubs and it went away.

Was part of the 5 months proving to them that it was happening? So if I call them will they not believe me?

I don't think it's the IWE, unless it's a grinding noise...

It may be the cam phaser/start up rattle issue that's discussed in the Engine section:

This ended up being the IWE, and they replaced the front two.

I have the cam phaser noise, but only on cold starts where the truck has been sitting for more then 3-4 days. The oil is totally drained back to the pan. Goes away in 3-5 seconds and wont come back until the trucks sits for 3-4 days agin.

Im glad you got it taken care of, hopefully it wasn't too much hassles.
