Mine has this exact same chirp going on. I took it to the dealer to address along with the transmission shift issues. It has been with them a week now, so I can update when I get it back. Any resolution on yours?

I just posted a new thread on this - didn't find this one in the search, I guess because I searched for "squeak" instead of "chirp". But my truck makes the exact same noise. 2018 5.0.

Did anyone else notice that the frequency of the noise is about 4hz at idle, or about 1/2 crankshaft speed? That tells me the noise is valve train-related.

These videos were taken with the same camera phone shortly after starting each truck (cold) and letting each one come down from high idle. It's remarkable that these are the same engines!

It sounds like a lot of the other clips out there. Definitely not a “normal” sound, but my dealership says “unless it’s more pronounced, we can’t do anything.” At least I have it documented so when it takes a crap, it’s on them.

Here is a clip of my engine at idle. Sounds just like Sledneck64's and Jbscott's.
I went out to remove the serpentine belt tonight but decided against it at least for now since it was getting dark and I *ahem* wanted to watch the superbowl. Anyway, the sound seems to be coming from the passenger side valve cover area, not the front of the engine where the belts are.
My truck does NOT make this noise when it's stone cold. Once the engine starts coming up to temperature, the noise gradually starts up.

Mine makes the same noise. I can accept the injector noise but IMO it makes too many other noises to be normal. I'll try and isolate when it makes the noise. I have a 2018 STX with the 5.0, 4wd. Mine is going in next week to have the bumper/hood/ and fenders resprayed due to rock chips, so I'm having it looked at then. It's been fairly consistent.
I hope it's fixed as I love this truck,It's comfortable, has plenty of power, goes well in the snow.

2018 chirping like a song bird and dealer said they can’t find it
[QUOTE=Ozzstar;4727343]I have 355 miles on my new '16 5.0L 4x4 regular cab long bed. I have been hearing a slight chirp/squeak at idle. I have worked on cars for over 25 years and this one is new to me. I could hear the noise mostly when I would stand by the passenger side door. If i walk to the front of the truck the noise is barely noticeable. This noise sounds exactly like when a serpentine belt is making noise (chirp). I pop the hood and the front of the engine sounds 'normal', belts and pulleys. I get under the truck to diagnose the issue and focus in on the bell housing area of the transmission where i hear the noise pretty well, the sound is in that area......so i keep listening and sure enough without burning the **** out of my ear, i get real close to the PASSENGER side catalytic converter, i can hear the abnormal noise inside the cat. Of course its not a loose heat shield, it's internal. Usually the cat will rattle but this guy is high pitched. Drivers side sounds fine. Damn... ain't that a bitch. Glad I got 60K more miles of warranty left.
Thoughts on the subject including any one else experience this issue on a '15 or '16 model.?

2018 Ford F-150 XLT 5.0 v8 and this thing chirps like song birds on a spring day. Dealer put new idler arms on the belt thinking they got it and yet here’s what it sounds like. It’s got 5700 on it and seems to do it on cold starts at idle much louder when engine warms it quiets down.
