Squealing Brakes and Parking guidance error messages at highway speed
Brakes were loud had them serviced still loud. A problem we had with our 2004 S500
When we are driving on the highway or even in traffic the Parking guidance comes on says its not available and to consult owners manual. The dealership act like this is normal. I can't believe it is. We are changing dealerships. Any advice or is this unique to my W221
