I returned to the dealership and found out that my truck has been sitting there for over two weeks for investigations on the vibration issue. I have a GMC case open for this. Last week, they called me and said they could not replicate the issue, which I found trivial. I requested to ride with the technician again, and they agreed. During the ride, we reached a speed of 64+ and the vibration started. The technician claimed he could not feel it, so I took the keys and placed them on my leg, showing him how they were vibrating like crazy. I also pointed out that the passenger mirror was still while the driver's mirror was shaking like crazy. Finally, they agreed to do some more in-depth inspections, which I found puzzling as to why they didn't do that from the beginning. I'm waiting to see what comes next. By the way, I received a link from GMC where you can open a dispute and get it settled if you have a car issue and it's still under warranty. https://bbbprograms.org/programs/all-programs/bbb-autoline/how-bbb-auto-line-works

Latest update: Unfortunately, the issue came back, and I have visited the dealership four times now since I thought it was resolved. But no, the car is still losing balance. I opened a GMC case, and the truck is at the dealership again. However, they are so slow in just getting to touch the car. If you are in the Houston area, never use Sterling McCall to buy or service your car. One of the service managers just told me I should get used to the vibration. Unbelievable. Back to the issue, I believe it could be something with the rims and not the tires, but let us see what they say now.

Hey, here is the update on my case: I left my car at the dealership, and they kept it for over 3 weeks. At the end of the first week, they called me and said they had serviced the car and it was ready to go. I went there, took the car, and tested it on a very smooth road. However, the vibration was still present. I informed them that I would not take the car back home and would open a case with GMC if the issue was not resolved. They assured me that they would do everything possible to fix the issue. However, two weeks later (I'm not sure why there was such a delay), they called me to say that they needed to order 4 new tires because they found 3 uneven tires that couldn't be balanced and were causing the vibration. I took the car for a road test and I can confidently say that replacing all the tires resolved the issue. I'll give the kudos here to the dealership, which took accountability and fixed it. Also, they gave me another brand-new Denali Ultimate to drive while I was waiting for mine to get fixed. It sounds like my case was not as the other ones before; I hope you all get yours fixed, too.

My problem started when I felt a vibration immediately after leaving the dealership with a new truck. I returned the truck right away, and they offered to replace it with a new one because the paperwork had just been completed. However, when I tested the new truck, I felt the same issue. They mentioned that the trucks had been sitting on the patio for about three months, so the potential balance might have been lost. Therefore, they offered to rebalance the tires on the original truck. I thought it was a tire problem as I only felt the vibration when driving over 60mph. I got the truck back the next day, and as soon as I hit the road and picked up speed, I felt the vibration again (less than the first time), but it was still there. I called them and told them the issue was still present. They asked me to bring it back, so it has been two days since I dropped it off at the dealership. I see through the app that they are testing it, and they have not yet called me back to pick it up, so I assume they are still investigating. I strongly feel it is the tires, as I don't feel the vibration at lower speeds. I'll keep you all posted as soon as I get it back. Side note: The loaner car they gave me, which is exactly the same truck, 1500 Delnai Ultimate, has the same issue, too.

Has anyone found a solution to this issue? I have the same problem with my brand-new 2024 Sierra 1500 Denali Ultimate. It is currently at the dealership for inspection. Interestingly, the spare truck they gave me, which is also an Ultimate, has the same issue."

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.
