And they still have not fixed it...

 

Dealing with a 2014 with vibrations and now seeing more 2015's pop up with the same issues - GM keeps pumping them out and screwing their dealerships with trying to clean it up...

 

Dealerships probably feel like the clowns with shovels following horses in a parade

Yep....im assuming the 16s will be the same

Mine was way better when they replaced the bent rim several months ago, now I'm wondering if more than one rim was bent. Mine does well up to about 70 mph, then at 78, which I drive nearly 85% of my commute, it shakes off an on, but not always. If I get on the onramp and put the foot down and it's smooth, I actually notice it more than the usual shake. I can notice it in the driver's seat, then I look over and see the passenger seat moving back and forth. Put my hand on the passenger seat headrest and feel the vibration. Next oil change is in about a month, will have to have them go back to the drawing board. It's 75% better than it was before, but still not smooth as silk, in which a $55k truck should be. Grrrrr.

That's exactly it... We didn't pay $50k for trucks to shake like this. Dealers want no part of trying to fix it, but that's part of selling the frigging things like this. If the dealers don't want to deal with it, they can drive every truck they get, and send GM back all the ones that shake.

I have stock 22"s. And have the harmonic vibration buzz most noticeable around 75-85. We have toll roads here with 80 mph speed limits. So thats all I feel

Yep, sounds just like mine. Do you think the dealerships are balancing the 22s incorrectly? The two second-gen tacomas I had were probably the most sensitive trucks I've ever seen to wheel/tires, so bad that when I lifted them I kept the OE wheels and used high quality spacers to make the tires fit. There was a special finger adapter Toyota used to balance their tires via the lug holes, since the wheels were not hub centric. I don't have a vibration in my steering wheel at all, so if it's the wheels or tires it's one or both of the back ones, or it's the driveline somewhere. I have a couple buddies at work that have 2014s with the 17 or 18" alloy Z-71 wheels and they have never said anything about having any vibrations, I wonder how many people with those wheels experience this?

Not sure if they're balancing te 22 s wrong but mine has 20 s with same problem and it started a year later....

Have you ever tried a different set of wheels/tires? Has anyone had the tire slipping on the wheel issue with the 20 or 22s? If your wheels are slipping in the tires that could explain it happening a year after the fact... If that's happening it's really ****ed up though...

This thread has become quite depressing but even more loathsome than anything else. About every 50 pages you have new members discovering their truck is vibrating after a few thousand miles of ownership posting the same problems with the dealerships doing and saying the same thing with little or no resolve and several members on their second vibrating GM POS going through the same dog and pony show. I believe it was Einstein that said "Insanity: Doing the same thing over and over again and expecting different results." This really needs to hit GM in the pocket book before they will ever take any action. At least after coming here you know you're not imagining things, your 50K dollar truck is really a vibrating POS and NO... it's not likely it will ever be fixed.

I haven't tried different wheels & never marked my tires to check for slipage....

They have no idea what the hell the problem is....they keep having the dealers do the same few things like road force balancing etc instead of really figuring it out on GM s end

They know what the problem is. The problem with getting it fixed is that car companies are ran by business men and accountants that answer to share holders, and the price to fix it has not yet exceeded the price of ignoring it. Like I said until it hit's GM's bottom line they won't do anything. Expect to see 2016 owners on here within the next few months with the same problems going through the same motions.

It's sad but I think you are right....

2016 Yukon XL Denali owner right here (with vibration and pressure/buffeting issues).

 

I've asked for any folks from LA, Las Vegas or Detroit to let me know. I have pursued quite a few automobile rags/newspapers/online sites and was able to get a response pretty quickly from one of them. He wants to drive one that has both issues (or even just one). He also has contacts at GM that I'd bet no one on here has (through their dealer or not). For as many folks that have issues, I would have thought I could have found at least one owner.

 

For what it's worth I also created a Facebook group so please feel free to join.

I was thinking of this today. Wait until you have to replace the tires. You will have to do it at a dealership because the road force spec on these trucks is less than what the tire industry spec is. Therefore good luck finding a tire dealer wheeling to swap tires out to find the perfect match. Or should as consumers we force our GM dealers to pay for RF since the Silverado spec is tighter than the tire industry threshold.

    • I’m out of ideas on this truck. 2020 Silverado 1500. 5.3 135,000 miles. Has a p0308 and p050d codes. Smokes From exhaust when cold. Compression test passed. New plugs, wires and coil on cyl 8. Same issue. New coil on 8, no change. Replaced injectors, no change. Bore scope showed oil pooled on the piston after sitting overnight. Pulled head and had machine shop check it out. No cracks. Stem seals looked good, replaced anyways. He also ground valve seats. Put it all back together and still have the same issue. Bore scope shows oil on the piston again. Leaning towards maybe a cracked ring but unsure. Cylinder looked good when the head was off, no scoring or scratches. Any ideas on what else I should look for?  Appreciate the help 
    • Just want to make sure it is covered by Special Coverage N232395310 Evaporative Emission Purge Pump 2021 Silverado 1500 Custom 2.7L L3B ~100k miles I'm getting DTCs P146B and P146F. VIN 3GCPWBEK2MGxxxxxx   I spoke to a person that works at GM and he said it is not covered after checking my VIN.   Is there anyone here who currently works for a GM/Chevrolet dealership and has access to GM Global Warranty Management / Investigate Vehicle History who could explain how the VIN eligibility is determined?   thank you    
    • Thanks for all that information, I might purchase one and see if it will work for me, if not they may let me return it! Yes for sure the tires are definitely within limit for my truck empty, and when I do tow I'll definitely make sure to raise the rear psi for the amount of weight that's going to be on it.
    • Yes exactly, more and more these days people/companies are afraid of liability issues so its easier just to say no rather than risk putting their neck on the line.    I will say with the Autel unit or when I used it last year on my truck, it wasn't like I could choose the 2025 model year or even the 2024 model year as that option was not there to manipulate the placard pressures but had to go back to 2023 or there abouts and then it showed up as an option, odd but that was how the software was then and I can't say one way or the other now as they throw out updates every so often. I still would talk to your tire dealer though to start with and they may do it for nothing but also they may have a comment on a better unit to purchase. All I know is that one of the large tire shops in my area happens to use these Autel units for their use and set them up to use the wifi and all of that jazz for constant updating because each tire tech has one handed to them by the shop but I just plugged it into my laptop to update it and yes if one is bought it has to be registered so you can get the link to do updates and then the unit has to be updated before its even used. I am not at all techy so it took me a bit but anyway just a heads up for anything you buy, most likely it will need to be connected to a computer to access the internet to have it updated to the latest software version before you can put it to use.   If your truck is near empty, those tire pressures you listed are a very safe upper range pressures to carry the weight, both the front and rear as I know they could be run lower yet with an empty truck. And if its a trailer and not some motorcycle your going to strap onto the front of your truck on a rack, you shouldn't have a need to inflate your front tires if your at 55 front already, its the rear ones that would need more air if you have much hitch weight. 
    • Thank you, I'll check that Autel scanner out and see if it will work for me! Ya I can see GM's point of view if they lower the psi set value for someone and the person sell's the truck and the new owner puts the factory tires back on then their could be liability issues cause the psi warning light wasn't coming on when the tires were under inflated for towing their load and then it might be able to be traced back to GM lowering it.
