I have a 2005 Legacy 2.5GT. Great car..but it is my first Subaru. Upon repeated braking, such as the descent for a mountain, I am encountering steering wheel wobble upon braking....very similar to rotor warpage. Subaru insists that the rotors are perfect. This only happens after repeated braking and usually at higher speeds. It will not occur in around town driving. Anyone encounter this issue with any Subarus??????
