My 2018 5.3 made that same exact sound as my 2021 5.3. -
Anybody see this yet?

My 2021 is one of the 2021's that does not have DFM. It's in V8 mode all the time. I wonder if I'll be good? -

I saw this too. How can the Chevy 5.3 have this notice but not the Sierra? -

Sewing machine sound are the injectors. Do a search. Plenty of people complain about the sewing machine sound. It's normal with DI engine.

If it sounds like your blinker is on, it's the vacuum pump. My truck only has 600 miles on it and it's been like this from day one. I finally go in on Saturday for them to officially diagnose the sound. Here is a video of mine. It's the metallic/intermittent sound that sounds like the blinker is on.

2017 5.3L Engine noise

[mention=126037]Haider320[/mention] I was just going to send you a message to make sure you saw the video in the first post. It certainly sounds like what you were describing by a blinker type noise. The post above yours says they replaced the high pressure fuel pump and it fixed the issue for another member who was experiencing the same noise. Yes, thanks. I just read that. On the YouTube link, there are several guys saying they have the same sound. Either GM has some faulty fuel pumps, or some of them just sound like that. My best friend has an 18 and he says his makes the same sound like mine. Kinda like the vibration issue. Some have it, some don't. -

I know this is an old thread, but has anybody determined what this sound is? My 18 makes the same sound. -
Well, of course the truck was warm by the time I got to the dealer so they couldn't hear it. I had a recording of the tick and the tech said it sounded like the high pressure fuel pump but said they all do it. It's bs but what can I do? Screw it, it's under warranty. If something breaks, I'll get it fixed.
