Hi,experiencing vibration at most speeds above 40 MPH. I was told by the service mgr.that the Perelli's needed to get about 200 miles on them, then the vibration would go away.After 500 miles problem still there.Going into shop on 9/7.An $86,000 dollar car should have no vibration,anyone having the same problem?
Thanks Jim

 

I don't know if you spotted the title of this forum, but it is for the X350 series of XJ saloons from 2003-2009. You car is the later (and current) model. You might get a better response if you post into the X351 forum.
