Sierra 1500

  • 9,000 miles
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.

Sierra 1500

  • 7,649 miles
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.
