My 2004 Porsche Cayenne S has steering wheel vibration issue. It occurs only when braking at medium pressure, at 40 ~ 30 miles/h speed. The front rotors have been replaced 3 times with the genuine parts in the past 6 months but the problem is not solved. For a few days after the rotors were replaced, the vibration has gone but recurred within a week. I am driving this car mostly on the highways at normal speed. The mechanics told me that they don't think there is brake pad sticking issue. Considering all above, I wonder the problem is really caused by the warped rotors. However, whenever the rotors were replaced with new ones, the vibration disappeared at least a few days and came back. Could you help me to get out of this?
have the same problem?
