I have a Brand New 2024 Denali Ultimate Sierra (6.2L 10 Speed) experiencing high vibration on day 1.  I picked up from out of town dealer on Saturday and took to Tire Store same day.  They checked balance and stated OK.  GMC Dealer checked and replaced both front break rotors.  Still have vibrations.  GMC Dealer checked tire balance and stated they were not balanced and the Tire Store got it wrong.   The truck still vibrates at highway speeds. Any suggestions?  This is a very expensive truck and rides rougher than my 2019 Silverado LTZ with 6.2 L and 10 Speed.

my issues is the smoothest roads with the truck at steady hwy speed vibrates, on rougher road it isn't noticeable because of the road, for me only above 68 mph all the way up to the speed limiter. Ver

I'm 90% sure it is the front axles.

Vibration all over or is it one side?

 

The drive shaft usually needs to balanced after it is made.  You would see one or more pieces of metal welded to the shaft… perhaps one or all were knocked off the shaft or improperly spot welded:

Keep  taking it back to dealership.  You may be able to invoke the lemon law and get it replaced.

Both sides experience the vibration.

I'm experiencing the same issue with my new Denali Ultimate. I just picked it up last Friday and it's showing the exact symptoms that have been described here. I took it back to the dealership and they told me it was a tire balance issue. However, after getting it back on Saturday, I still felt vibrations when I reached highway speeds of 65/70. I returned to the dealership today and they said they would need to investigate further. They gave me another Denali Ultimate as a loaner (it's brand new with only 12 miles on it), but the loaner vehicle is also experiencing the same issue.

I am experiencing the same issue with a 2024 Sierra 1500 Denali ultimate. I've gotten the wheels balanced twice and the vibration persists at highway speed. How was yours resolved?

Hi thanks for you concern.   I am not sure how emailing the social media department is going to help in getting this resolved.  Given my experience with GM and trying to solve these things, I don't have the time to waste at dealers for them just to tell me it is normal.  I have owned many new Chevrolet vehicles over the last 20 years and am very aware of how the service departments work when warranty work is involved.     

 

 

For those who follow this post for usefule information, I have a theory.   Since the wheel/tire location makes no difference and it seems like this vibration, at least on my truck is pretty centrally located, I am willing to be that the front axle shafts/joints are somehow out of balance.

You are probably getting close.   Most drive shafts are balanced at factory where they are made.   The small thin steel weights are added to the shaft to balance it.   Check your drive shaft to see if you can see an outline of where a balance weight used to be… or maybe it was never balanced.   The quality of most post covid vehicles has not yet gotten back to the pre covid vehicles.

Sorry, I wasn't clear.  I am referring to the front half shafts since mine is a 4WD truck.  Driveshaft seems fine.

 

I agree, i had a 2022 refresh before this and the day i brought this home I noticed many things that I can't see how they got past quality control.   Door gaskets hanging off the door, not snapped into the holes in the door, dirt under the paint in various spots, loose and clunky driver seat, etc etc..  My last truck was an LT with cloth and jump seat, this one is leather with center console.  I had no issues with the driver seat on the other one.  As a matter of fact, aside from the bad software for the radio that was problem early on with all the refresh, I never had a single complaint with the last truck.    

 

I agree, for the price we pay for these vehicles, the quality should be much higher.

 I am having the same issue with my 2024 Sierra Denali Ultimate.  They said it was a bad tire and replaced, but the truck is still vibrating.  Not sure where to go from here.  It is exactly like the original posters video.  The seat keeps on shaking!

      2026 DENALI 6.2L

      By pyoung62 · Posted

      I agree with Tim.  As tech heavy as engines are these days, no way I’d be an early buyer of the new 6.6.  Of course, I bought my ‘26 Denali w/the 6.2 after dumping my Tundra with it’s defective 3.5 liter imploding engine disaster, so I’m a little gun-shy.  That said, my 6.2 has been rock solid.  I don’t drive it like I do my BMW Z4 M40i, but I don’t baby it either.  I got a V8 for a reason.  But I’m averaging 18 around town and 22 highway.  I have seen 24 highway as well when I wasn’t loaded up heavy.  Considering my Tundra with the twin turbo V6 only got 14.5 in town and 17 on the road, I’ll take the 6.2 all day, every day.  If I were you, I’d grab a ‘26 while you can.  Inventories are probably gonna start dropping and I’ll bet the deals will start looking sweeter as well.

      Can you add a 360° Cameras hard button to a 2021 Sierra?

      By ShowMeShooter1332 · Posted

      I am curious if anyone has figured out a way to add an hard button AUX or 360 Camera switch to the center row of switches. I have a 2021 AT4, and want to split the hill decent button and add a 360 camera button so that you don't have to go into the center display and locate the camera functionality, etc...   My father's 2024 Yukon XL AT4 and it has a hard button, see below. I found this thread on the Yukons, but it seems like there may not be a part number for the 2021 sierras. https://www.gm-trucks.com/forums/topic/255339-adding-hard-button-for-camera-on-2021/ Anyone else figured this out. Seems like it would need to be a custom switch!   I am getting ready to install the auto stop/start eliminator, so would be nice to knock them out at once.     Upvote1Downvote0Go to comments

      Oil Consumption

      By Chuck FB · Posted

      Through the years it hasn't been my typical method as I tried to drop oil on an engine that was hot from having been worked, however that was not always practical and had to fire up a unit and let it warm up reasonably well and drop the oil when I had the time to do it but am referring to not only vehicles but a variety of farm equipment and highway tractors etc. However on a vehicle where one is crawling under it and the exhaust is nearby to ones body and if wanting to pull the plug without danger of being hit with boiling hot oil or attempting to remove a HOT oil filter, its sure safer and easier to not have everything smoking hot and can remove the filter right away when under the vehicle and let it all drain. Of course its not the end of the world if a bit of oil stays in the engine that might have eventually found its way out, I like to get out as much as possible but any oil changes that take place in shops would rarely be sitting around for very long at all before the plug is thrown back in and filter slapped on and oil poured in and sent out the door quick like. There would be very little time spent ( assuming they even did it ) in starting the engine with oil to fill the filter, then waiting to verify the level on the stick. A good reason to check ones oil level shortly after a shop changed the oil on a vehicle just to make sure its correct and to look under for any oil around the drain plug or filter.
