My truck had the vib when i took it out for the test drive. It had 4 miles on it when I drove it off the lot. They told me it was a simple fix.

 

On one repair they gave me a 2016 Silverado and it should worse than mine. I really hope GM works this out. They do have a great truck.

Just out of curiosity, has anyone experienced a change (for better or worse) by putting better tires on the vehicle (i.e. the Michelin's I keep hearing about)?

I went with BFGOODRICH All Terrain KO2's, it was my last resort before looking to trade the truck in. Luckily mine was fixed by that, but my vibes were not as bad as most other member, thankfully

I found out something that may be of interest to some. I work for a Junior College that has a GM Certified Training School (many other major manufacturers do as well). I spoke to the lead GM Instructor if he as ever heard of vibration issues in 14 and newer trucks? He immediately said "yes, very common, they make the frame so stiff it tends to manifest itself in steering wheel" I told him my story about Dealer replacing all Goodyear tires and Road Forced Balanced" them. But, still vibrated. Told him I took it in again and they RFB's one tire again and told me everything was now within GM Spec's. He indicated that the Goodyear's were not great tires, and suggested Continental tires if on a budget, or Michelins if you can afford them. So, he went on to say that RFB, if not done correctly will not necessarily balance tire properly. So, IMO he was aware of the issue and said I need to get RFB's by recently instructed Tech. on RFB's. He clearly said many of the tires were flat spotted, especially if they sat on the dealer's parking for a long time.

 

Here's the part that blew me away: When I was talking to him in the School's shop, I noticed the students were working on relatively two new Silverado's. They were working on electrical systems as they both had their hoods up. I asked "where do you get these slightly used trucks'? he said "they are "buy backs", where he surmised the customer just insisted on a buy back because dealer was not capable of RFB's or they just thought the slight vibration is simply not acceptable to them. So, now we at least know where these trucks go. They are not put back on the street, but rather donated and I assume GM gets some form of tax break. Makes sense to me.

 

So, I believe many need to find a dealer with a Tech. who has taken a recent RFB class offered by Hunter, and insist the newly trained Tech does the work. This helped my vibration significantly. Do I think it is the "cure all'? No, but in my experience it helped to level where I can live with it, assuming it does not get worse in time. My dealer claims it is now in Spec. when the recently FRB's and Pico'd it. If this is true, GM's level of acceptable of tolerances certainly suck.

Unfortunately not all of the trucks are donated to a schools or shops. there have been many many cases of people finding their own trucks that they had "bought back" for sale again on the dealers lot. Similarly if one files a lemon law case and opts for a cash settlement instead of having it declared a lemon and repurchased by GM, those trucks do NOT have their title branded as such. any vin check will still show a clear title even though the truck is a mess. Theres ALWAYS a loophole they can slide through.

I have a 2015 Silverado CC

My original tires-SRA- were replaced at 7000 miles due to sorry tires and vibration. Replaced with Michelin LTX2 and I still have the vibration.

Road force tested and rebalanced and still have vibration !#!!$!$!!

Tech says MINOR vibration. Asked him if he was paying for truck would he call it minor?

He just looked at me............Trying to decide if I can live with it.

I finally got 4 tires with the rfb numbers 6 and under. 90% vibration gone. The only problem I have is when I change my tire for snows in the winter. Right now it was covered under warranty but what happens when I need to change tires? I do not want to dismount these seeing how they finally got it right. I don't think I should have to fork up money for new rims for my snow tires especially when they ran fine on my 2013 silverado with all the same options.

Keep asking the dealer to fix it. Have they checked pinion angle, etc?

Flew into FLL today and picked up a 2016 Siverado 2wd with 412 miles at National Rental Car. Got on the turnpike and oh wow...never been in anything that shook that bad. It is manageable below 65mph. Above that it shook the bottle of water right out of the center console. I would be pissed if I just had bought that truck.

Well this is my first go at the dealer with vibration issues. I have new tires and they were just balanced. Took it to the dealer and he said its common for these 2014 trucks to be out of balance. i laughed to myself because i knew that would be the first thing he said. i did have him drive with me and he noted the vibration, ill let them do whatever need be and if the truck still shakes when i pick it up ill turn right around and go back. Wish me luck. I can say they gave me a 2016 as a loner with 800 miles on it and it was smooth as silk from 70-75.

I've removed the snows and put the 22s back on. Different vibration than before. Starts at about 115 and goes away about 128. Convinced its tire related. My service manager agrees says he will road force balance them again. I tell him he gonna wear that hunter out. I'm going for replacements, hoping Michelin.. wish me luck. There's only about 8000kms on them and they're already whining on the highway. Bridgestone Duellers... had them on my 2009 louder than a tractor trailer with 30k on them. I suppose I could drive speed limit OPP pretty expensive at 130. GM makes a great truck though aye.

Oh forgot to add. Service Manager was at some kind of dealer conference. #1 concern from the dealers was the vibration problems these trucks have. Thankfully only a few have it. He insists that GM is looking for a solution though... He's a nice kid :) . Probably any day now lol. Yous can get the news guy to cancel the article, not necessary.

I don't trust GM as far as I can throw a 2000sq ft house. lol. The fact that they have known about this problem since 2013 when the 2014 MY was released and they still haven't fixed it is utter bullsh*t. In addition, if the #1 concern at the dealers convention was the vibration, that means that there is one h*ll of a lot more than only a few.

 

In other news, I have changed my servicing dealership, I am now taking my Chevy to a GMC dealer. I physically went in and talked to the service department and asked them if they have had anyone coming back with a vibration in the trucks, he nodded his head yes.. I asked if they have had any luck removing or alleviating the vibration, and again he nodded his head yes. I replied, RFB tires, replace tires, replace rims, replace driveshaft, replace rear end, adjust timing and exhaust pressure, lift body off frame slightly? nodded yes again. To keep this from getting any longer, I have an appointment for Friday morning to take the shop foreman for a ride, he will also be looking at trying to fix my radio problem...

Hope new dealer can help you out. Mine is at least trying and mine is 90% better.

    • Hello hello looking forward to expanding my knowledge of the 2026 2500 HD that I just bought.   Truck has 3500 miles on it four-wheel-drive crew cab and I’m about to put a 6 1/2 inch BDS lift on it 18 x 10 -25 offset with 37’s   Already have the wheels and tires just waiting on the lift install in about three weeks   Question what surprises am I not gonna be happy with?  I’m not new to lifted trucks so I know that acceleration towing gas mileage all that is affected..   Question is those of you that have this truck this powertrain with a 10 speed Allison and have done the mods that I’m doing,,, how bad is it? Is that Allison constantly gonna be hunting for the right gear to go into? And what about towing, acceleration, fuel consumption as mentioned?    Lastly how come I can’t find any ring pinion gear set up for these axles and when could I expect to see them?   I apologize if there’s any typos I’m doing speech to text on my iPhone.    
    • I've got a 2013 2500 6.0L Flexfuel. Drove the truck earlier today with no issues. Went to run an errand tonight and noticed key fob wouldn't work. Figured battery was dead, so replaced fob batter. Still wasn't working. Grabbed my other set of keys with the other fob and that one wasn't working either. So I manually unlock truck and insert key. Interior lights come on, dashboard lights up, turn key and truck starts. Turn truck off, like a moron, and try starting again. This time no crank, no click, no nothing. Lights still come on and dash lights up, but now I'm getting a service 4wheel drive, service tire monitor, etc. Check voltage on battery and Im showing 12.2v. Throw my battery charger on it and give it 15 mins and try starting again. But still no crank no start. Decide maybe its a bad battery, run to autozone grab a new one and put it in. Same issue. Disconnect battery and let it sit for 15 mins. Try again and still nothing. I had managed to roll the windows down earlier as its a humid night, but now I can't get them to roll up. Power locks are also not working now. Then randomly I try the key again, and it fires right up. Immediately I roll up the windows as we have nothing but rain forecast this week. I shut it back off wait 30 seconds and start up again. Worked a 2nd time. So turn it off, start putting things back together. Try one more time, and back to no crank no start. And now the car alarm starts going off. Had to disconnect battery and leave it that way for the night as I don't think my neighbors would appreciate my alarm going off again tonight. Any thoughts or help would be appreciated. 
    • No one will care for you like you care for you. Do what you can for as long as you can. IMHO of course. 
    • How about them NICKS!!! 
    • Hi there.  Long time lurker, first post.    i have read the previous posts regarding the water ingress problem with this emblem.  I bought my 1500 SLT the  summer of 2025 new and after reading the MANY problems with these emblems failing I decided to install one anyways.  As per a YouTube video, I sealed ( or tried to) this sign with silicone sealant around the outer perimeter joint and the holes that were already somewhat sealed on the rear plate of the emblem.  And installed the connector assembly using dielectric grease on the connectors. The installation looked great and worked well for about 4 months……then FAILURE.  Grrrrrr…… I live in the great white north and wash my truck weekly in an automatic car wash  to keep the salt off.  Let me tell you that removing the old, failed emblem is a whole different animal than removing the OEM individual letters without removing the grill assembly. Mainly because the illuminated logo is built differently than the original letters which  you can remove the red surface lettering with a knife or some kind of blade which gives access to the tabs which hold the logo onto the grill. So I had to essentially destroyed the old emblem to remove it. Doing so killed my chance of doing somekind of autopsy on the failed , old logo.  But there was plenty of water inside when I ripped it apart.  Prior to installing the new assembly I tried it with the old harness and it works fine.   Does anyone have any insight as to where the water is getting into this emblem? I intend to seal the new logo with slow curing epoxy this time around using a syringe.  I think this newer emblem may be an updated unit which I hope GM got the vendor to fix. It has an October 2025 date on it.    If this one  fails,  I am just going to revert back to the non-illuminated letters….AFTER PULLING THE GRILL.    Any thoughts on sealing with epoxy would be appreciated. Thx!   Doug
