THE BRAKE VACUUM PUMP SEALS ARE LEAKING. THIS ULTIMATELY WILL AFFECT THE BRAKE ASSIST AND POTENTIALLY RESULT IN FAILURE TO STOP THE VEHICLE WITHIN PRESCRIBED STOPPING DISTANCES CREATING POTENTIAL FOR A CRASH. THIS PROBLEM WAS IDENTIFIED BY THE LOCAL BMW DEALERSHIP IN HIGHLANDS RANCH DENVER. OCT 1 2010 BMW RECALLED 198,000 VEHICLES INCLUDING V8 AND 6 SERIES VEHICLES FOR THIS EXACT SAME PROBLEM BUT MY VIN SHOWS NO RECALL NOTICE HOWEVER IT HAS THE EXACT SAME COMPONENT EXPERIENCING THE EXACT SAME ISSUES AND BMW IS REFUSING TO ACKNOWLEDGE THAT MY VEHICLE SHOULD BE RECALLED AS FOR THIS VIN THERE ARE NO OUTSTANDING NOTIFICATIONS. I REPEAT THE EXACT SAME ISSUE IS BEING EXPERIENCED ON MY VEHICLE AS WAS THE REASON FOR 198,000 VEHICLES RECALLED FROM THE NOTICE OF OCT 1 2010

PLEASE CONSIDER A MANUFACTURER'S RECALL SO THAT THESE OBVIOUSLY DEFECTIVE WARMERS CAN BE CHECKED OR REPLACED.
