NHTSA complaint: 2006 BMW 750LI — SERVICE BRAKES
BRAKE VACUUM PUMP BOOSTER HAS FAILED DUE TO CONTAMINATION EVEN AFTER BRAKE BOOSTER SUPPLY LINE WAS REPLACED IN DECEMBER, 4, 2010. WHEN VEHICLE IS IN MOTION, THE CAR LOSES POWER TO BRAKES, BRAKE PEDAL FEELS HARD AND VEHICLE TAKES 20-30 FT LONGER TO BRAKE EVEN IF PUSHING DOWN WITH MAXIMUM FORCE. THIS CAUSED VEHICLE TO TAKE AN INFINITE AMOUNT OF TIME TO STOP, WHICH RESULTED IN CAR NEARLY RUNNING INTO ANOTHER VEHICLE WHEN ISSUE OCCURRED. LUCKILY I SWERVED OFF HIGHWAY UNTO MEDIAN. THIS ISSUE CAN RESULT IN DEATH OR CATASTROPHIC ACCIDENT AS BRAKE BOOSTER VACUUM PUMP IS AFFECTED IN SUCH A WAY THAT BRAKE POWER IS 50% LESS THAN NORMAL, LOW TO NEGLIGIBLE BRAKE POWER MEANS CAR DOES NOT STOP NORMALLY, IT TAKES MORE TIME TO STOP, WHICH CAN LEAD TO DEATH FROM REAR END COLLISIONS, FREAK ACCIDENTS AND EVEN RUNNING INTO PERSONS OR OBJECTS WHEN PARKING.
