I took delivery this past Tuesday of a New Silverado Z-71, 4 wheel drive, crew cab. Shortly after driving it I began to notice a rhythmic- harmonic vibration. It seem to be a 1 second vibration, then 1 second of no vibration, then 1 second of vibration and so on. Seems to be worse between 60-70 MPH. I have contacted my friend at the dealership where i purchased to see if there is a bulletin or anything from GM about this issue.


Anyone else had this issue or any ideas? Truck has about 560 miles on it.

 

There is a post already started with the 2014 chevy v8 that new owners were complaining about. Just hit a search

 

I couldn't find one using the search button, its probably there, just couldn't find it. Can someone steer me to that thread.
