I've noticed the same squeal on my 2020 6.2. From what I could find out its just "the sound of the 6.2, get used to it".

Kinda embarrassing to have my brand new truck sound like an 89 Oldsmobile on startup though....

Thanks, yes quite embarrassing for sure on a $60k truck when you're trying to show them (friends) upon startup lol.  Another member on the FB Trailboss group said his does the same and sure I'll try and get used to it, but does anyone actually know what the root cause is?

 

Appreciate it!

Sounds like it may be a serpentine belt.  The one on my 5.3 has just been replaced under warranty, it's only got 10k on it.

Was kind of thinking that as well or a pulley, but it doesn't seem to be coming from that area.  Going to take it in next week and see what the stealer says and I'm sure it will be along the lines it just sounds like that, but want to make certain as it's kind of annoying!

I would remove the serpentine belt, then start it up cold and run for a few seconds to see if it still does it.

What squeal?  I don't hear it.  And I've driven 89 Oldsmobiles.. They sounded just fine.  No squeals.

2019 6.2L here with the same squeak.   Sounds like belt/pulley to me.  For those that have it does it also squeak for a shorter amount of time after a stop/start event? Mine does.

Hmm turn your speakers up...goes away at end of the video.  Seems unusual to me...

I did have the speakers all the way up :(  Maybe I'm just tone deaf :(  I'll try again tomorrow.

Any resolution to this from anyone??? I have the same squeal on my 2020 TB 6.2. Like all say, it goes away after about 30 seconds. But it sounds like an old Monte Carlo for the fist 30 seconds. lol.

 

Now that I am seeing it's not just me, I feel slightly better but would still like a fix.

      Towing In Loose Gravel

      By JimCost2014 · Posted

      If what you are doing works, keep doing it:   4LO (Four-Wheel Drive Low) should only be used in extreme low-speed, high-torque situations such as deep mud, heavy snow, steep rock crawling, or extreme inclines/declines, and you must follow the correct engagement procedure to avoid drivetrain damage. Intended Use Cases Deep mud or snow where traction is extremely poor and you need maximum torque to get unstuck Trucks Only+1. Rock crawling on steep, uneven terrain forum.fullsizechevy.com+1. Extreme inclines or declines where you need to control speed and maintain traction solutionsphere.blog. Heavy towing in low-traction conditions (e.g., deep sand, ice) carclubsusa.com.

      Towing In Loose Gravel

      By rdonarski · Posted

      Hi,   I work a steep boat landing that has patchy blacktop going down the hill and soft sand/gravel at the bottom. Due to low water levels, it's not always possible reach the blacktop. I've had to help several people get out this year already and with fall coming, I'm anticipating more. I always use 4L. There was a gentleman there today with a 2500 HD (actually 2 - him and his son both have them) and they were trying to get his son's wake boat out. This gentleman swears that you should use 4H in the soft gravel. Says he was a farmer and you always use higher gear when stuck. I was wonder what your thoughts on this are? If I'm wrong, it would be good to find out before things get busy.

      Roll up bed cover experiences

      By Bill Lemmond · Posted

      Looking for feedback from users of roll up aluminum slat bed covers who have had it for more than 3 years. I prefer the aluminum slat style over supported vinyl covers due to security and the capacity to support a light load. The slight loss of bed opening when rolled up is not an issue. Presently have BAK Revolver the "industrial grade vinyl overlay" on mine is shrinking & coming loose at the rear and on both sides in addition to cracking at some of the folding joints. Truck lives outdoors in NC latitude. Can't justify the steep price to replace it with another one if that's the expected lifespan. Do you have a better alternative?

      Thanks, your last sentence is the root of my problem, outdoors truck and southern latitude = UV overload. Looking at replacing with Rough Country powder coated aluminum slat roll up model.

      Tire fitment

      By JakeD · Posted

      I’m looking at putting a lift in my 2024 gmc sierra 1500 elevation trim, has anyone had any luck with fitting a bigger tire under the rear for a spare?? Was gonna go with a 4 inch zone lift Also what wheel and tire size setup are you all running? Wondering if I can get away with keeping around the stock size a 33 inch, and just get some new wheels to have enough back spacing then I can just keep my original spare tire I have under the truck now.
