Mine does pretty much all the time, I've had the tires road forced and that made things worse, then I took the shop manager and the customer care rep out for a drive and it wouldn't do a thing. They said to give it a week or so and if it happens again bring it back. It costs $150 to have the tires road forced...

So I have this vibration. Bought the truck with 21 miles on it,and now have 6000. I brought it In for the oil change, and told them about the vibration. Thinking it would be a balance problem. They had it for 2 days with no fix. I have to bring it back on Monday for the to check out the rear end. Everything I have been reading there is no fix, so some dealers say it's normal other have no idea and have to bring in GM engineers. After paying so much money for a truck and GM getting so many complaints, from what I read starting in 2103 about the same issue. Why wasn't something done or said about the issue, before they keep selling a vehicle with this issue, and no fix. (From what I have been reading)

Do any of the trucks do it that doesn't have the rear locking diff

Interesting question. If the differential locked for some reason and failed to unlock you would definitely know it because when making a sharp turn on hard pavement, the wheel on the inside of the turning circle would squeal, as it could not rotate at the same speed as the outer wheel.

I asked about the locker because alot of the time mine starts to shake or vibrate more when going around turns

Interesting observation. Consider this...if there is some unbalance in the tires, wheels, or axles on both sides of the vehicle, then the "phasing" of them side to side can greatly affect the total vibration felt. When the unbalance force is "in phase", it is usually much higher then what they are opposite to each out (out of phase). When they are opposite, they tend to cancel each other out. Now, because the outside wheel turns faster when going around corners, the wheels side to side will constantly be changing phase to each other. Could explain what you are observing.

 

I had an 86 Vette with a vibration I never did get rid of that you could feel the vibration come in and out of phase on long, sweeping, corners on the highway.

My 2014 rally 2 has the problem with locking differential and the loaner a Ltz z71 has it too . They both are doing the same in between 70 and 80 mph. The ls v6 loaner they gave me once didn't have any issue and am sure didn't have a locking dif. So far the have balanced the tires, put 4 new ones and balanced them . My truck is at the dealership again . Still the same . What's odd is that the first day or two after they changed the tires it was much smoother. A week later pretty much worst then before the change . You might be onto something with the locking rear differential... Seems like it's more of the higher end ones having problem. Let's hear what other have to say

I also sent you PM, but my main question is - what exactly are you experiencing that you are pinpointing the locking rear dif.?

This issue is a pita!! The reason why I said the previous poster might be onto something with the rear locking differential is because you do feel it more when on a bend for example on the highway or on a uphill when your tires could have a bit of uneven traction. Somehow sounds like a possibility. Then again it could be anything at this point. Rear locking differential is an option and you have it too . Seems to me so far that the ones who have the issue have this option. Let's see if anyone without it vibrates too. I know one of the loaner without locking differential didn't vibrate but then again had only 500 miles.

2014 Rocky Ridge 1/2 ton bought at Kenny Ross at Somerset,Pa. Of course vibration and shaking. Long story short , service had me up there twice for no reason 3 hour drive in total. One time replaced drive shaft, second time balanced rear tires and they forgot to do vibraton test . Filed a complaint and Somerset Kenny Ross, said I had

to take the lift off for th to fix it. Rocky Ridge disagreed with Somerset Kenny Ross, and that they are suppose to diagnose the problem so if it's Rocky Ridges fault they would pay for the problem and Kenny Ross in Somerset is known for this type of behaviors. In the end Rocky Ridge found another Kenny Ross that upholds the warranty and will diagnose the problem and get it fixed . The only problem is its to far for me. I guess I will pay down and trade in . Last Chevy I buy ever again. Through this hole process they ignored the recalls and never fixed them. I will make sure others are Aware of Somerset Kenny Ross in Pa.

2014 1500 reg cab v6, viberation between 65 & 75 mph, sounds like subs bumping when it does it, notice it totally quits if you go into 5th gear running the same speed, go back into 6th comes right back. To me that eliminates (tires, driveshaft, rearend and etc..) leaves it to be transmission related in my opinion. Truck went to the dealer with 375 miles on it, they have had it for 27 days with no fix.

To finish my post above, dealer has turned driveshaft 180 deg, replaced driveshaft, replaced muffler bracket, deactivated fuel management system (no difference), tried body insulators (to cover true problem). Monday will be day 30, dealership has tried but long enough is long enough, my turn to roll the ball.

I actually tried a little earlier today the whole transmission theory on my vibrating loaner @ 76 mph on cruise control . For me no change whatsoever, I put it in manual 6,5 and 4 th . Still the same vibration. Also tried turning off the traction control.... No luck either

Does your truck have rear locking differential?? Is it 4wd? Or really basic ?

    • I am sure that was quite the pass experience and not a great place to experience during the winter when the conditions are not good. I've seen video of that pass and also more detailed information and pictures about the wrecks at that one hair pin turn where tractor trailers have flown right off the cliff and I am sure from all the warning signs that you know the exact curve that was !. After all there is a reason why a song was made about Wolf Creek Pass !. By the way and I didn't realize this either when I bought my truck as its nothing I even thought of that would be programmed into the cruise control and this occurs in either the basic or the more advanced cruise that controls your distance behind a vehicle and that is the brakes going down a hill are being applied as soon as the vehicle goes a certain speed over the set cruise speed. While it certainly does force downshifts in the transmission as you found out with cruise on while going down hill, its also dragging the brakes as needed to keep the speed controlled to what the cruise was set to. For me, I find that unsettling simply because I have no concept then as to how MUCH brake input is being used a and just how hot are those brakes getting and the wear factor as well. I can see that system getting a person into trouble on long mountain grades while pulling a trailer as it would not only be standing on the brakes of the pickup without any driver input, it would also be automatically applying the trailer brakes and it could cause a run away unit by overheating the brakes. Its one thing on a shorter hill and if the driver allows it to do its thing but on a long mountain grade is where things could get so out of hand. As someone a while back on this forum said, they had someone following them at night I believe on a down grade and had the cruise set and the person behind them could see the brake lights being energized all the way down the hill. I figured when I saw your comment that you didn't know and would have no way of knowing that your truck was applying the brakes and that you would and rightfully so assume you only used the brakes when you pressed on the pedal to slow down more than the cruise set speed for the slower sharp curves. So its good knowledge to know this about the newer GM trucks, certainly when doing any descending on long mountain grades. In the future try kicking off the cruise and use the the manual mode on a pass to see what that is like as I know myself when I first experienced it I thought no way can this engine be holding me back this well and tried the same hill in manual mode and sure enough the engine was revving way up and still could not hold the trucks speed down like it could in cruise mode.    Fuel mileage, that is where a really low sleek type of car can do better at higher speeds, certainly it starts sucking fuel too but a tall pickup is pushing massive amounts of air and also allowing a lot more air under it and the tow mirrors as in elephant ears pushing through the wind  as well. Driving like grandpa is about as good as one can do when driving one of these if trying to get the best fuel economy they can. I bet these trucks would get the best mileage they can if driven on a freeway in Florida if not busy traffic at a sedate speed and that sea level elevation without hills, vastly different then Colorado !.
