09 Sierra vibrations

[Jeff Smith]

I have had my new 09 Sierra for a month now and it has a vibration at any speed. I have taken it into the dealer twice and they said that it is normal. The passeger front seat shakes as you are going down the highway. Just wondering if anyone else has the same kind of vibration in their GMC.

This is very disappointing to spend $40K and not have a smooth ride.

well i have an '01 sierra and my pass. seat bounces around like a bobble head... it got better with a tire rotation and new shocks but i would not expect a problem like this at all out of an '09. could be as simple as unbalanced tires or summin.... vibration and shaking should not be normal on any new vehicle by any make or model.... i know this doesnt help you at all sry... the only thing i can say is try a different dealership. ill ask around to see if any new gmc owners i know have this problem and get back to ya if anything comes about...

The dealer has balanced the tires and reindexed them. They also have replaced 3 of the tires. None of this has helped any. I bought mine 3 days before the 60 days money back policy came into effect. I might tried to see if they will take it back.
