My truck has some vibration but not as bad as the 2014 w/ 3.08 and 18"s I had first. Still not happy w/ ANY shaking on a new vehicle. Describe it best this way- when look to the right in my empty truck the passenger side sheet is vibrating like it the seat is equipped w/ a massage function. On my first truck equipped w/ 18s I could fell it in the passenger side seat and also the wheel a bit, on this new one w/ 20s and all terrain suspension I only see it as evidence.

 

That being said- my buddy just bought a full loaded SLT sierra and had real bad shakes and a humming sound, turned out he needs a whole new rear end.

 

I'm having my truck looked at as soon as I need my first oil change. Looks like GM will be eating some money on my repairs in the near future. I don't care if my shake is minor or not- if the rear end is indeed defective from the factory (something about pinion gears not matching up, chewing u where the drive shaft meets the rear) then I want it all new period.

So you got rid of a truck that had a vibration to get another one with a vibration? Not trying to be a smart ass but I almost did the same thing. I was looking at trading to Sierra with the standard box, I was going to lose $5000.00 on the trade and then my buddy said "your going to look like an idiot if this new truck has a Vibration too." When I bought my truck I didn't notice the vibration right away so I could see it happening. Same buddy told me not to buy a first year truck either and i wish i would have listened to him. I will be trading it off but it will be on another make.

 

This is my 4th new chevy since 1999 and I've never even been close to being this disappointed in any of them. It's not just the vibration, the tranny shift like junk when driving in town, I could go on and on.

Got the truck back today. It ended up being a tire issue after all. Apparently the tire shop didn't check for tire roundness like they were supposed to do. I had one tire that was way out of spec. They said that the road force maximum allowed value on trucks is usually around 26 lb and that tire was over 32 lb and couldn't be brought into spec. So they ended up replacing it but they went through two tires since the first one they put on had an even higher number - 64 lb this time. The second tire came in at 19 lb. There is still a small amount of vibration but at 80 mph it is still less than it used to be at 75 mph and only starting to be "noticeable." I won't know more until I am able to get out on the highway for a longer trip. I may end up replacing all of the tires with a different brand but for now the ride is much better.

 

What made me turn away from a tire issue is that I had the tires rotated with no change in the vibration and the last time they balanced the tire, they were supposed to check for tire roundness as well. They said what was happening was a torsional vibration. The tire was feeding off the opposite tire on the front of the truck causing the variation in the vibration that I was feeling. Basically as I turned the tires would go in and out of phase with each other, creating the oscillation in the amount of vibration that I was feeling. When in phase, they would add together, amplifying the vibration and when out of phase, they would cancel each other out - almost since it never when away. This is a new one on me as I have never had this issue on any vehicle (this is my 7th vehicle).

 

The service manager came out and talked with me a bit on this issue. He said that the re-time of the drive shaft that they performed on my truck usually fixes the issue on about a third of the trucks. The other fixes have been new drive shafts to new axles if the issue is not a tire or wheel issue. My suggestion to everyone is to make sure your tires are not too far out of round first, even if this requires going to multiple tire shops just for the sake of a second opinion. Hopefully this helps some of you.

I have a 2014 crew cab 5.3 and I too have a vibration problem. It seems to come and go. I hear a wobble sound between 35 and 40 mph and I feel vibration in the wheel at 50 and it makes my hand numb. Sitting at the dealership waiting for a fix.

Good news and some redemption for my many postings on check the tires like my post #91. All vibration would go away on yours if you could find a shop that knows how to true a tire and balance on the truck. Short of that, road force where they rotate the tire on the wheel if necessary is your next best bet. Having drive shaft balanced is the second step if still mild vibration.

 

Replacing OEM is highly recommended but trueing and on truck balance is still recommended on the non-oem.

I find Michelin LTX, M/S-2 or A/T-2 to be good. I find the M/S-2 to be just as good or better then the A/T in mild off road and mud.

 

I test drove a '14 cc, z-71 4wd and it had what I though was flat spotting as the tires ride was as bad as I have seen. We drove about 20 miles in very warm weather and it did not clear up. If I was going to buy that truck, I would have had the dealer swap out oems for Michelin and if road smooth would then buy.

I got rid of the truck because I realized I didn't like the mushy suspension, SUV tires, 18" rims, and terrible 3.08 rear when compared to the All TErrain model I now have. The vibration was something I just chalked up to bad tires, but it could be something else who knows. The new one I have doesn't have any vibration you can feel, the truck tracks straight, its just slight vibration that I can see by monitoring the empty seat next to me.

 

Which new truck are you gonna get? The 2nd year Dodge or a Ford that will be antiquated next year when they introduce their "first year 2015" - either you're ending up in a new design bud.

I have a 2014 Silverado double cab. It had a slight vibration around 70 mph when new, now it has 2800 miles on it and the vibration is gone. Rides and drives perfect.

 

One other comment, I recently had the chance to drive a friends new 2013 Ram Big Horn. There is no comparison when it comes to ride and drive...IMO The new Silverado rides and drives so much better. Truth be known, my friends Ram reminded me of my old 2006 GMC truck. Vibrations in the cabin and cowl shake, along with sloppy brakes, vague steering and body roll around corners. I assume Ram will catch up in the next 8 to 10 years, if Fiat doesn't kill the brand off before then.

Anybody noticed if the cylinder deactivation (aka active fuel management) is kicking in while they experience the vibration? I believe you can see the status on the driver info screen in the middle of the dash. I could see a truck lugging and vibrating if 4 cyl is not enough power to keep up the current speed. I test drive a chevy z71 yesterday and when accelerating I noticed a big slip when flooring the gas pedal, engine RPMs shot up 5,000 when shifting. I was planning on ordering a 6.2 with 3.73 gears but after reading some of the posts, vibration and tranny issues I may hold off.

I picked up the truck today and the service advisor said they can't really tell where the vibration is and that I should be happy mine drives better than some of the other ones. Not the right answer. They didn't even attempt a fix. Once I hit 50 mph the steering wheel vibrates and I don't like it. I have had 8 other chevy trucks in the past and this one as quiet as it is rides the worst. aside from the vibration it is just harsh every time you hit a bump. Maybe cheap shocks or just valved to stiff.

STex...Thanks for your input. Sounds like good advice. I'm going to try the Michelins.

      I want to apologize in advance for the length of this... I just need to point out the details. It’s time GM does something for us who own 2014-2015 models, trucks I’ve dubbed "the engineering guinea pigs" thanks to personal experience and the myriad of complaints in this forum.
       
      Good day to all of you. I’m presenting you an issue that is causing more concern to my safety in my truck than holding a gun to my head. Starting this off by stating I made the grand mistake of taking my truck in to get the steering update instead of checking ground connections myself. Doing this update bit me in the ass within a week of getting my truck back. Let’s just say that after I received my truck from the dealership in far beyond worse condition than I sent it in with, I’m getting consistent and far worse problems after updating. My truck shut off on me completely, losing control of steering and everything, while approaching a red light at about 45 MPH...with my younger brothers in the truck. I took it to the same dealership that same day, and they weren’t able to do anything. I was beyond frustrated. I’ve never had any vibration at any speed until my service. Now I’m getting vibration at 70mph. When I lightly press the brake, I’m hearing a rotational sound coming from my left front wheel, my mechanic says it’s the bearing but with our trucks having sealed bearings, I’m going to be looking at an $800 hub assembly. Just this Saturday, I made a 45 minute drive up to Ft. Lauderdale and as I arrived, I noticed my engine was producing a sound almost like a lifter noise, even though the dealership serviced my lifters(or one specific lifter, not clear at the moment as to what it was). When I got back in my truck after a few hours, I had no lifter noise...WTF? This is getting out of hand.
      Here's the part that has me worried: ever since my update, my volt meter is below the half mark all the time (never happened beforehand) and I noticed that my headlights flicker and dim, along with my dash lights sometimes. When I press my brake and use my turn signals, the lights dim significantly and brighten back up but flicker. With my turn signal, my headlight dims when I engage it and as it blinks, my headlights dim and brighten with the blinks. Just the other day as I was backing up out of my buddy's house, my backup camera froze and I got a "service rear camera" message on the display. I’m so confused, how does an update manage to mess up my truck? I'm beyond pissed. The only good this update did was actually improve the shifting slightly, even though I’m still having that infamous 1st to 2nd rough shift. Other than that, this update makes me want to tell GM to F-off and move onto ford or something. Yes, I’m that serious. I’ve been a Chevy person all my life, the majority of my family owns Chevy's... this is just getting out of control. I've searched up all these forums about this and haven’t found too much. Already have links saved and screenshots of individual posts about all this, but I need more insight.
      Did I make the mistake of buying a first-generation truck? I’m not looking forward to pursue legal action, which will end up costing me an arm and a leg, on top of that I probably won’t benefit much from it. Realistically, I’m also not looking forward to switching sides just yet. I want to make sure I’ve exhausted all my efforts before I make a drastic change like that.
       
      This was my dream truck... and I was beyond blessed to be able to own it, and I had so much plans for it. Now? It’s looking like a nightmare, and I've got the urge to get rid of it.
       
      HELP. ME. PLEASE.

      I have a 2016 Silvarado LTZ Z71 4x4 with the 8 speed... About 13,500 miles on it and it's started to develop a "shudder" and it's been shifting harder. On cruise control it will shudder at around 1300 rpm with speed staying constant. I've driven it in manual on new roads at 35 MPH and it also shudders around the same RPM range. We're talking about vibration enough to shake the steering wheel. Almost the same effect as driving over bumps in the road. When driving it very aggressively at higher RPMs the issue isn't as severe. Also when drifting, aka letting the vehicle decelerate, the issue goes away. 

      Has anyone had the same issue with the 2016 8 speed? Any solutions?
       
      I'd like to have an idea of what the problem is before going to the dealership tomorrow. I bet $100 they'll tell me it's the tires....
       
      Thanks for input,

      I have a 2012 GMC Acadia Denali AWD.  Since I have purchased the vehicle 2 years ago, it has had a vibration issue.  It seems to vibrate at speeds 60 and over and tends to do it more when accelerating and after sitting for a few hours or more.  Dealership thought it was the tires.  After replacing the tires right after it was bought, that didn't help.  30,000 miles later replaced the tires again still has not helped.  They even took tires/rims off a brand new Enclave and put on my vehicle and it still did not fix the issue (used as a test to see if it was from the new tires and/or rims).  Also, the tires that were on the vehicle when we purchased it used, wore unevenly (I think they called it cupping or something along that lines but cant remember).  Regardless in our eyes, this vibration issue is causing the tires to wear quickly and wear in an uneven manner.  The second set of tires wore the same way.  We are now on set number three.  The steering wheel also shimmies back and forth (kind of like the tires are extremely off balance or kind of like when your rotors are warped and your applying the brakes).  The issue with the steering wheel is not happening when braking so it's not the rotors.   Now they did find one issue, the car was almost bouncing up and down a bit also, and they found the torque converter had to be replaced.  While replacing the torque converter, they inspected the drive shaft to make sue nothing was wrong with that.  The car has had the alignment checked multiple times and the tires have been balanced to the ying yang including road forced balanced at more than one facility.  Some of the things I know the dealership have checked are the following:  all suspension parts, motor mounts, axles......they even hook it up to a picoscope to monitor the vibration to see if it could pick up where the vibration is coming from.  I mean it's almost like your on a 1940's exercise vibration machine the whole time your driving it....your just shaking the whole time your driving it and you can feel it in the steering wheel as it's shimming back and forth.  It  has been check multiple times over the last two years.  FOR THE LOVE OF MY SANITY, CAN ANYONE COME UP WITH ANY SUGGESTIONS......I THINK THE DEALERSHIP AND ME & THE HUBBY ARE BEYOND FRUSTRATED.

      Truck started to make a squeaking noise this weekend, took it to the dealership on Monday. Dealership called Tuesday and said that they could not find anything wrong with the truck and that this sound is normal. Take a look at this video so that you can hear and understand what I am talking about.  https://youtu.be/aERzjGAX-aU
      Does this sound normal to you guys? I also put water on the belt and the noise was persistent so it does not appear to be the belt. Any help would be greatly appreciated!
