Hate to be the bearer of bad news but there is no motor mount recall. A newer tsb for loosening the the mounts and adjusting the motor then retightening in a specific sequence is available. It is possible that a tech called TAC and was given a new motor mount p/n but I haven't heard of that yet.

Well folks, I did it. After all the failed attempts at the Chevy dealer I traded it in for a 2015 Ram 1500 Larame. I have to agree with the other folks on here that have done the same thing, it was th

Apparently you and the other customer reps don't care. If you or GM would care y'all would put more effort in the matter. Just coming on the forum and stating the same repetitive posts and being a 3

Well I have some good news and bad news about my truck vibrations. Good news is that my truck has a significantly less vibration at speed. The bad news is my truck has significantly less vibration. Fo

Hey guys. Just wanted to throw in my two bits. I was having major vibration issues on my truck at certain speeds sometimes at 50km then 80 and 110km. I had discussed with the dealer about this and they had looked everything other on a couple occassions and told me nothing was wrong then finally one of the service techs had come out and asked me if I would be interested in trying out different rims/ tires on my truck (looked like he had a theory in mind) so i did. I originally had the 20's on the truck and we had swapped for the 18's instead. similar diameter only approx .37" difference. I drove the truck right away after the swap and no vibration. been driving it for the past two weeks this way and still have not come across any vibration. I had made the dealer buy my 20's back off of me and give me a credit to keep the 18's. The mech had said that he noticed a lot of the trucks that did complain about vibration had the 20's on them and he figures something is off. Either way I am just putting in my story of what happened. For others here on the site that have further vibrations issues I hope they get solved and if I here more then I will post it.

When I started this post I thought I might be the only one, and know body will believe my thinking I was just trying to stir the pot. I had know idea if others where having issues. Sadly I never thought it would have turned into this.

Man , You could churn butter in that thing. I have only had mine on interstate maybe three times. Not as bad as yours. I can see the bottle spinning. :omg:

but that's normal, just the way trucks are supposed to ride

 

GM designs its vehicles to ride that way, everything is normal

 

every single truck on the dealers lots drives and vibrates the same way so its normal

 

why don't we accept it when they tell us this :bs:

 

great video and mine does it about the same at times and sometimes not as bad

2014 Z71 2WD

 

i have the vibration shakes like everyone else and i bought a new set of rims 17" for the stock tires, same shake. Took it to the shop i bought the rims from twice and no better. I then bought new rims and tires 22" and shake still there at 35 to 45 and again at 74mph. Took it to the dealer and they noticed it and gave me a rental for 5 days. I went back and they said the problem was my aftermarket rims and tires. I also felt it in the rental. Tried to put up with it was a couple weeks but driving me nuts.Called and talked to the service manager, he said there is a know issue but no fix. He then said he wants to check my rims and tires again and put stock ones on and see if it still shakes. really!!! So i made another appointment but not for two weeks. He said they are very busy with other recalls. Plus he is getting the regional service manager with some vibration detector.

I also noticed that there are no 2015 1500 silverados out yet at least around here, is GM making sure they are ok or anyone else know?

Has anyone that has this issue on a 4wd tried to drive it with the rear driveshaft removed to test for the vibration?

Thought about that last winter. Never came up with a way to seal the output shaft of the transfer case.

i'll say this, I don't drive a lot. my truck sits on the driveway for a week at a time and sometimes it goes a month without being driven. I mostly use the car or motorcycle and the truck gets used mostly just for pulling the boat and this has been my pattern of truck use for nearly 35 years.

 

that said in the entire 35 years I have NEVER had any vibration or feeling of flat spots on the tires, if there was any it was so negligible that it went unnoticed completely.

 

I will concede there might be the possibility of ever so slightest of flattening of the tire from not moving in a while but this it corrected before you leave the driveway with a few revolutions of the tire. I had my truck parked in the driveway for 8 years and never moved while recovering from health issues and when I finally took it for a drive the tires were perfectly smooth as always even though it needed new rotors and brakes from rusting in the driveway. if flat spotting EVER had a chance to be a problem then I think after 8 years it would have occurred but it didn't so I dismiss you notion with the concession that it may occur at some small minor unnoticeable level that cant be noticed or detected or used as an excuse for causing vibrations

 

the ONLY type of flat spot you would feel in the tires is if it gets dry rotted and harden that way and this type of flat spotting never goes away.

 

the notion that a brad new tire can have noticeable flat spots to cause it to be felt when driving is laughable on its face and insulting to anyone who has ever owened a motor vehicle. maybe someone who just fell off the turnip truck might believe such malarkey but as a wise man once said "don't pee down my back and tell me its raining"

 

 

I can feel the crosshairs of a liberal nut jobs rifle scope on me at this very minute lol.

This right here, I deploy 6-7 months at a clip, my vehicle doesnt move during that time, not once did I ever have a flat spot issue in 11 yrs of deploying

      Tire psi

      By jgaudet99 · Posted

      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.

      Tire psi

      By Chuck FB · Posted

      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.

      Tire psi

      By Chuck FB · Posted

      I had a similar but different response when I talked to the service manager where I bought my truck in that he said GM corporate won't allow them to lower the placard pressure setting as they would get their hand slapped but that of course they have the ability to make that change. His suggestion was simply go to a tire dealer or third party shop that is willing to reset the pressures lower. However I chose to buy a tpms tool and partly based off of this very forum as it had been proven to work on the 2024 model ( Global B system ) and while I could have paid lots for a full two way diag tool, I didn't want to spend that much and bought the recommended Autel TS 508 and it will reprogram the 2025 model and assume it should do the 2026 as well. However the tool is rather proprietary to reprogramming Autel tpms sensors so that is a function I will never use, where as a real two way scanner would have many uses but also have yearly subscriptions etc where this 508 is free updates for as long as they put updates out for the unit. In any event it worked to lower the placard pressures and I often use it to adjust my actual tire pressures although will check with a mechanical gauge as well sometimes just to make sure that tires tpms sensor isn't lying to me.    My suggestion is either buy a tool that you know will work to adjust the system or start out by getting the tire shop you bought your tires from to reset your truck and if after that you still want a unit to do it yourself, get one at that point.

      Tire psi

      By jgaudet99 · Posted

      Here is an image of a quick Google search about these tires on my truck and it's exactly same psi recommendation the Toyo tires company gave me!    I'm not looking for anyone else recommended psi or anything, I'm just looking to see if anyone knew a way to get rid of the factory low psi warning light, because I'm not running high psi and ruining my tires when I'm not towing!
