Having same issue now on a 15 suburban. Car make that noise and shakes a little at idle. Can’t hear the noise when I’m accelerating and when I stop at a light it comes and goes every 5 seconds or so. Glad I read this. I’ll keep you guys posted.

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.

OK I thought I was going crazy or just being overzealous because I had a jeep with so many issues but I have the 5.3 V8 2019 trail boss and my engine makes the exact same sound I didn’t know how to describe it to the dealer when I go back for my first oil change but it’s done it since I picked it up from the dealership same sound here at idle only has the RPM speed up it goes away sounds closest like someone here described is almost like a blinker sound . When I bring it in for its first oil change I will have master mechanic listen to it and see what they say I’m sure we could probably bring it in to different dealerships and get the different answers I see one person had some repair done but I’m wondering if that’s necessary or like you said maybe some of them just make noise as long as it  doesn’t fail I have plenty of warranty?

So is this kind of a “normal” noise then or is everyone having fuel pumps replaced?  My 2020 Sierra has the same clicking noise on a cold start after the rpm’s die down.

I have a 2018 5.3 V8 that goes to 4cyl on the highway. Mine has a slight knocking sound not as bad as this but it’s definitely not something I remember hearing when I bought it brand new. I’m going to the dealership Friday and I wonder if this is it.

      Cold start Miss, oil in cylinder

      By newdude · Posted

      Its coolant disguised as oil.   TSB 20-NA-166 -  20-NA-166 1..3   "To inspect for this concern, add coolant dye to the system, run the engine through warm up, pressurize the cooling system after warming the engine to operating temperature (let the engine cool overnight) and inspect the suspect cylinder with a borescope for coolant dye evidence. At times it may be necessary to remove the head for inspection. If the head casting line is the concern, the intake port will be wet with a coolant oil mix"

      Can you sample the pooled liquid, enough to confirm it is oil?   ...That its not fuel or coolant.   Also, make sure combustion gases aren't entering the cooling system.   Simply put, either oil being pushed up past the rings (this really isn't possible), oil leaking past the head gasket, oil leaking past the valve, oil entering through the intake air path. If none of this is likely - it may not be oil.   What could be likely is the fuel injector leaking down. A puddle of gas would still smoke and rough idle. (Same cylinder has the same problem after injector replacement?)   What is the crank time first thing in the morning, when the puddle would be present? Does it seem like the high pressure fuel pump needs an extra second or two to rebuild the pressure that injector 8 may have let bleed off? Check the fuel pressure via a scanner prior to starting the engine.

      Good information!  I didn't know about the dementia aspect and asked for a general for my second knee. I'd heard that recovery room time is usually shorter with a general.   The anesthesiologist talked me out of it and I had the spinal.  Inconvenience and/or discomfort is a small price to pay for reduced risk!

      This is for those over 70 years of age contemplating joint replacement surgery involving general anesthesia. Even some 55 yrs. ago when I took my pharmacology class the dangers of developing dementia in the elderly that had general anesthesia were beginning to be recognized. Over the years there has been some refinement in the cautionary warnings, avoid general anesthesia if possible if you've had close to 10 priors, especially over the age of 70 and/or a family history of dementia. I'm not including the twilight anesthesia induced by propofol often used in cytoscopies or colonscopies. Seriously think about seeing a neurologist and undergo cognitive testing before proceeding if any of those criteria apply to you. Spinal anesthesia may be an option in some cases. I'm in the above camp and although I could use a new right knee, I get fidgety according to a prior orthopedic surgeon when the bone saw spools up or maybe it was the smell of saw blade meeting bone, anyhow I may have one general anesthesia left in me which I will pocket for now and I'm choosing mind over mobility, anyway where did I leave my damn cane!
