Having a strange problem with my 2011 9-5 4cyl(A)30K miles. Only happens in the afternoon after being parked for about 8 hrs in 90+ degrees temperature. It feels like brakes are partially applied, real sluggish, high boost pressure, low instant mpg reading. When I apply the brakes it feels like rotors are warped. After about 10 minutes of driving symptoms go away and [COLOR=green !important][COLOR=green !important]car drives[/COLOR][/COLOR] fine. Doesn't happen everyday. Any help/suggestions is/are appreciated.
