The GMC Sierra has a terrible vibration from 70 - 80 mph. It has been in the shop 7 times over the last year, 9 new tires, and the vibration still continues. I have attempted to resolve the issue with GM but there has been no resolution. The truck feels unstable and like something is going to break on the highway which is a safety concern. This vehicle has issues and it needs addressed.

Brought in my 2015 GMC 1500 Sierra truck in for vibrations issues at high speed of 70-75 mph. After 4 attempts GMC Corp refuses to admit that there is a safety issues in driving this vehicle at a normal rate. They continue to remove and replace the tires. I have never owned a vehicle before that such vibration is felt in the cabin of the truck, passenger seat, foot petal, etc.that is so uncomfortable, that my wife refuse to drive in the truck due to its safety. GMC will not acknowledge any of these complaints but will say everything is of specs. Like others this is the worse vehicle I have ever purchased. Found more complaints like this has been filed, but same result, GMC will do nothing.
2015 GMC Sierra 1500 has a vibration problem. Been in shop 2 times so far wheels and tires balanced. Still the vehicles vibrates at speeds 77 and up at 85 you cant stand to be in vehicle have drove on new pavement, interstate, changed lanes still no change. I have a video on this as well as a lot of videos on U tube to show vibration at highway spends this is a problem on 2014 and 2015 and the dealership and GM states this is normal but will not give you that in writing they state they all do it.
