I am having an issue with my new 2016 Silverado and a vibration at highway speeds. I took the truck back to the dealer where it was purchased with around 340 miles on it. I was told they could do nothing until I had 1000 miles on the truck (they stated they could not get paid by Chevy for warranty items). That ticket stated they rebalanced my tires. This had no change. I took the truck back after 1000 miles. The dealer did a road force balance. This helped very little. Now, at 1345 miles, it is back in the shop. They state they will do a picoscope on the truck and check the axle. I should mention the underlying issue is a vibration that can be felt at speeds in excess of 65-70mph. It is more prevalent from 70-75mph. I have filed a complaint with GM, reference case 82405350103. This appears to be the same issue for the 2014-2015 models referred to as the "Chevy shake". one more attempt and I will likely start lemon law procedures in ga. I would like someone to seriously investigate GM on this complaint. There are plenty of forums with people complaining about the same issue. This could be an extremely dangerous issue if it is tire or wheel related, or even drive shaft related.

The issue(s) that I am experiencing all appear to be with the trucks 8 speed transmission. The first two occur during breaking and the third happens when accelerating from a 'cold' start. A description of each of the three major issues are outlined below: 1)during initial breaking the truck will begin to slow down as intended and without warning it abruptly accelerates/slides forward (see breaking profiles). This typically happens between 10-20 mph. 2)during breaking just before coming to a stop I experience a hard jerk or shudder (see breaking profiles). 3)during a 'cold' start, in the morning or after work, the transmission will sometimes slip and shift hard while pulling out of my driveway/parking lot. The issues are all intermittent.

I bought a 2016 Chevy Silverado 1500 ltz Z71 and it vibrates at idle and the transmission is slipping. I had already took it to the dealership to get it fix, but no luck. GM told me that is how the truck is designed to operate, which is hard to believe. There is absolutely zero help from GM to help me resolve the problem. I was given an option to trade it in for a new one at my own expenses or deal with the problem. Ford would not take my truck as a trade in nor will GMC. This vehicle can potentially by dangerous and a liability as the transmission seem to have a mind of its own and the constant vibration cannot possibly he good for anyone.
