Been through all vibration test tires wheels muffler fuel pump. They now want the engineers to take it and keep it.

 

this forum makes me want to buy a new 2014

 

The vibration is mainly between 55 and 80 mph. Felt most on the freeway with cruise control on. And the vibration goes away if you shift to neutral. She is back at the dealer now so I will let everyone know what they say this time.

 

So now they are buying it back?

 

Makes me glad I still have my '03

 

no, it is just in the shop. has been since wednesday.

 

I drove the truck I ordered today, salesman told me take out for a ride as long as you want. I was out for about and hour or so on highway and around town.I didn't feel any vibration, I didn't use the cruise control, XM radio was ok, lots of new toys to learn first thing was to find the odometer to see how many miles were on the truck. Should be mine by Friday.

 

If you have a rig with active fuel management (also called cylinder deactivation) the highway speed vibration (some also call it a hum like noise) is air being passed through the exhaust from 4 cylinders not running. However I have seen some trucks that needed the rear driveline replaced (Bulletin# PIP5140) but this limits the vibration to 30-40mph range. So really need more info, like what speeds is it occurring, is your cylinder deactivation turned off?

 

Mine is 30 to 45 and it sucks john hall Chevy won't do anything they are no help I call gm customer service they have done nothing I have sold my after market wheels and tires and it rides worse with stock ones on.
