I have a 2008 XKR, 64K miles, all maintenance properly done, last @60K. Suddenly, I seem to have a problem with the steering-too much overplay when the car is first started. It seems to disappear after a few minutes. Have taken it to the dealer, but they have been unable to duplicate. It over responds to steering unexpectedly, and the play in the steering is a bit scary. After a while it settles and does not happen until start up, again. Help?
