Only way to fix the vibration issues is to trade your truck .

Vibration is one of the new features that GM has introduced in the 2014 gmc line.

My 2014 gmc all terrain had a constant vibration but got worse after 20 min on turnpike,,could it be tires , transmission, torque converter. ??

I had 3.42 gears in my 2014 gmc after rear end was replaced I had a very bad vibration in the steering wheel, Watch out for vibration issue in steering wheel if they replace ring and pinion .

2014 gmc all terrain package with humming sounds at slow speeds it's the rear end,!!!! I was passing a car at 80 mph on turnpike had very bad vibration, GM has problems with the ring and pinions ,After the complete rear end was replaced then I start having a very bad vibration in the steering wheel ,Had vibration test done they found the ring and pinion was bad in the new rear end still had vibration after that dealer and GM were no help to fix vibration issues in the steering wheel I had to trade this truck for problems free truck I lost $ 9.000 because of GMC truck sorry for the bad news hopefully your dealer helps you take care of your problems.

I have a 2014 all terrain that had a humming sound when driving slow after 80 mph it became a shaking issue , dealerships replaced the rear end . Still didn't resolve vibration issues .

2014 GMC all-terrain package unresolved vibration issues started bringing this truck back to the dealership after 17 days of ownership. Rf tires no change, had really bad vibration in rear end at 80 mph , dealership replace complete rear end , pick up truck from dealership test drove it had a really bad vibration in the steering wheel made my hands numb after driving,kept complaining about this issue until a vibration specialist is a test on truck and determine ring in pinon was bad, new ring and pinion made vibration a little less in steering wheel ,but still a problem dealership says they cannot do any more for this truck they said to cal lGM corporate , So I did and had a customer service agent tell me there was nothing wrong with my truck so therefore they could not do anything for me,found out only 50% of lemon law cases are won due to vibration issues also dealership says they will not even give me book value for this new truck,I stood behind the GMC name for over 30 years unfortunately GM does not stand behind their customers or their products .
