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.

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!

    • I have a 2000 Silverado 1500 LS, whenever I put it into reverse and also in drive it clunks, the truck also feels sluggish when driving. Any advice/ideas ?
    • Looks like it's riveted to me. What is wrong with that 1? Welcome to the Forum!
    • Missing pieces of the Assembly   Detergency vs Solvency   Not the same thing. Detergency is the mechanism that surrounds solid particulates preventing amalgamation. Usually accompanied by a Dispersant whose job it is to keep those encapsulated particles in Suspension. Solvency keeps things that can be dissolved in solution.    Salt is a solid that can be dissolved. Pepper is a solid that cannot be dissolved. A detergent/dispersant is effective on pepper but a solvent is more effective on salt. As long as the solids remain in either state, dissolved or dispersed then they can be be removed with the oil upon change.    How many wranglers does it take to herd cats? Depends on how many cats your herding. How much sponge does it take to soak up water? How much water is there to soak up? Point is most oil blends start with some herding ability and next to zero sponge and recently even fewer wranglers are being sent to do the same job.    So you start with a dozen cowboys and zero cows but at the drive progresses you pick up cows along the way, but not cowboys. At some point you have more cows that the wranglers can handle and some leave the herd. Deposits. And the API has an acceptable number of cows they are willing to let loose. In the ideal world zero is the right number for he rancher but to the butcher....a few lost is fine. This cow is beat to death. Let's move on....   Solvency isn't something oils on the Walmart shelf care about AT ALL. Problem is, you motor does. Fuels driven varnish sticks rings and only a solvent can keep them in check. The bet is that the solids driven portion that plug the expander rings and the oil drain backs and VVT screens and AFM screens will be an issue long before varnish is. Not that it wont be but if they market well enough the consumer can be kept ignorant enough to either believe it is "normal" (A quart in 1 or 2K is normal) OR is kept at bay longer than the first owner is likely to hang on to the unit. Solvency cost money.    Now the OEM's have John Q. Public buffaloed into the belief that the number cows accumulated along the trail is a known and predictable CONSTANT. It isn't. Nor is the rate at which they crossed paths with them. Only the number of wrangles is constant. Or was. Each new generation of oil sees fewer and fewer of them.    So what happens when the number of cowboys is lower (lower TBN) with each seasons trail but the trial is longer (OCI) and the number of cows along that trail continues increase? (Conditions that promote deposits).    For awhile the blenders were on to something. Better bases are harder to degrade (fewer cows) but that was overtaken by a longer trail (OCI) and improved breeding (More cows) while continuing to reduce the cowboy staffing levels (TBN/Aniline #).    Marketing has been successful. We've fired most of the staff, cows breed line bunnies, the trail is ten times longer and we've convinced the boss his ranch is in better shape that it ever was.    That kids is just the cleaning side. The side few pay attention to.
