2006 BMW X5 Brakes Problems

The brake vacuum pump has leaked a small amount of lubricating oil into the hose. This contamination resulted in a loss of power assist braking. The loss of power assist in braking has increased stopping distance and lead to a near vehicle crash. No indicator lights were present. Repair: Replacement of the brake vacuum line with one that contains a check valve, eliminating the possibility that oil will reach the brake booster; as well as the brake booster and brake master cylinder will also be replaced.

TL* THE CONTACT OWNS A 2006 BMW X5. THE CONTACT STATED WHILE DRIVING 30 MPH, THE BRAKE PEDAL WAS DEPRESSED HOWEVER, THE VEHICLE FAILED TO RESPOND PROPERLY. THE CONTACT STATED THERE WAS NO WARNING LIGHT ILLUMINATED. THE VEHICLE WAS TAKEN TO RICHMOND BMW (8710 W BROAD ST, RICHMOND, VA 23294) TO BE DIAGNOSED. THE CONTACT WAS INFORMED THAT THE BRAKES NEEDED TO BE REPLACED. THE BRAKE MASTER CYLINDER AND THE BRAKE BOOSTER WERE REPLACED. THE CONTACT RELATED THE FAILURE TO NHTSA CAMPAIGN NUMBER: 10V446000 (SERVICE BRAKES, HYDRAULIC) HOWEVER, THE VIN WAS NOT INCLUDED. THE MANUFACTURER WAS NOT INFORMED OF THE FAILURE.

I PURCHASED A 2006 X5 4.4I (N62B44 ENGINE)USED WITH 138,000 MILES. WENT TO LEAVE DRIVEWAY, CAR WAS IN REVERSE, PRESSES BRAKES TO ADJUST MIRRORS, LET OFF TO KEEP BACKING OUT, HAD TO PRESS AGAIN FOR ANOTHER ADJUSTMENT, I LOOKED UP AND I WAS DRIVING THROUGH THE BUSHES IN MY FRONT YARD. BRAKES WERE PUSHED BUT NOT ENGAGING. I THOUGHT THAT TO BE ODD, SO I WANTED TO RUN TO A CERTIFIED BMW REPAIR FACILITY. I WAS IN TRAFFIC GOING ABOUT 40 AND HAD TO UTILIZE THE BREAKS AGAIN, THE CAR STOPPED. WITHIN ONE MINUTE I HAD TO PRESS AGAIN AND THE CAR WOULD NOT STOP, I PUMPED THE BREAKS AND THE PEDAL WAS SO HARD THERE WAS NO GIVE. I PLOWED THROUGH A RED LIGHT ALMOST CAUSING A SEVERAL CAR PILE UP, AND WAS FINALLY ABLE TO GET THE VEHICLE TO STOP. AT THE REPAIR SHOP, I WAS TOLD THE VACUUM PUMP WAS LEAKING OIL EVERYWHERE BECAUSE IT WAS BUSTED, THE OIL WAS BACKING UP INTO THE MASTER CYLINDER AND HAD MIXED WITH THE BREAK FLUID AND THE BREAK BOOSTER WAS BAD. I AM HAVING TO PAY 2400 FOR THE SERVICE WHEN IT WAS JUST PURCHASED 3 DAYS AGO. THERE WERE NO WARNING LIGHTS ON AT TIME OF PURCHASE WHICH WOULD HAVE KEPT ME FROM PURCHASING WITH CASH. THERE ARE STILL NO WARNING LIGHTS ALTHOUGH I HAVE TAKEN DOWN SEVERAL BUSHES BECAUSE THE X5 WOULD NOT STOP AND ALMOST CAUSED A HEAD ON COLLISION BECAUSE THE X5 WOULD NOT STOP AGAIN. THE 2007 X5 HAS BEEN RECALLED TO THE EXACT SAME ISSUE WITH THE EXACT SAME DIAGNOSIS AND SYMPTOMS, THE 5 SERIES FROM THAT YEAR WAS ALSO RECALLED. JUST NOT THE X5 DUE TO AN OBVIOUS OVERSITE. THIS IS A VERY DANGEROUS VEHICLE WHEN IT IS OPERATED WITHOUT BEING REPAIRED. THE VACUUM PUMP, BREAK BOOSTER AND MASTER CYLINDER ARE ALL PART OF THE RECALL, WHICH IS EXACTLY WHAT A BMW CERTIFIED MECHANIC STATED NEEDED TO BE REPLACED ON MINE. I

THE BRAKES PEDAL BECOMES HARD AND IS UNABLE TO STOP VEHICLE. THIS OCCUR WHILE THE VEHICLE IS MOVING. IN ADDITION THE BRAKE PEDAL IS HARD WHILE STATIONARY AS WELL

SUDDEN LOSS OF BRAKE FUNCTION AND LEAKING BRAKE FLUID DURING NORMAL WEATHER AD ROAD OPERATIONS. AFTER DOING RESEARCH THERE IS A LARGE GROUP OF SIMILAR YEAR MAKE AND MODEL WITH THIS SAME ISSUE.

BMW X5 BRAKE BOOSTER FAILED. I WAS DRIVING IN TOWN AND ATTEMPTED TO STOP AND NOTICED THAT THE TRUCK NEEDED MORE BRAKE PEDAL PRESSURE THE LONGER I APPLIED THE BRAKES. THE PEDAL BEGAN TO RISE AND THE TRUCK WOULD BEGIN TO CREEP FORWARD UNLESS MORE PRESSURE WAS APPLIED TO THE PEDAL. I DROVE TO THE BMW DEALERSHIP TO HAVE A RECALL PERFORMED ON THE PASSENGER SEAT OCCUPANCY MAT. DURING THAT VISIT I INFORMED THE SERVICE WRITER OF THE BRAKE ISSUE AND ASKED IF IT WOULD BE CORRECTED UNDER A RECALL AS WELL. I WAS TOLD THAT MY VEHICLE WAS NOT COVERED BY ANY OTHER RECALLS. I RESEARCHED IT AND FOUND THAT SOME BMW X5'S WE'RE EXPERIENCING SOME ISSUES WITH THE BRAKES AND WERE BEING RECALLED BUT NOT MY VEHICLE. I ORDERED ALL NECESSARY PARTS AND REPLACED THEM MYSELF. WHICH CONSISTED OF A NEW UPDATED PUMP, ALL UPDATED OEM LINES WITH CHECK VALVES AND A NEW TRW OEM BRAKE BOOSTER. RESEARCH SHOWS THAT ENGINE OIL VAPOR TRAVELS INTO THE LINES AND UP TO THE BOOSTER WHICH CAUSED THE RUBBER DIAPHRAM TO FAIL IN THE BRAKE BOOSTER. THESE ARE ALL THE SAME PARTS MENTIONED IN THE RECALLS ON OTHER BMW X5'S COVERED BY THE RECALLS.

BRAKE BOOSTER FAILED WHILE STOPPED WITHOUT ANY WARNING LIGHTS

TL* THE CONTACT OWNS A 2006 BMW X5. WHILE DRIVING 65 MPH, THE BRAKES FAILED WITHOUT WARNING. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE BRAKE BOOSTER, CYLINDER, AND VACUUM FAILED. THE VEHICLE WAS NOT REPAIRED. THE VIN WAS NOT INCLUDED IN NHTSA CAMPAIGN NUMBER: 10V446000 (SERVICE BRAKES). IN ADDITION, THE BRAKE PADS WERE REPLACED A YEAR AGO. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND INFORMED THE CONTACT THAT THE VEHICLE WAS INCLUDED IN THE VIN AND THAT IT WOULD BE AN OUT OF POCKET EXPENSE. THE FAILURE MILEAGE WAS UNKNOWN.

RECALL : BRAKE VACUUM PUMP RECALL MENTIONED THAT ALL X5 AFFECTED VEHICLES WERE BUILT FROM SEPTEMBER 12, 2006 THROUGH MARCH 18, 2010. MY CAR HAS SAME ISSUE AND ITS BUILT YEAR IS 2006 BUT COMPANY SAYS THAT MY VIN DOESN'T COME UNDER RECALL. THIS DOESN'T MAKE ANY SENSE, WHEN I HAVE ISSUE WHICH CAN CAUSE SERIOUS ACCIDENT THEN THEY SHOULD FIX IT. I AM NOT GETTING ANY HELP FROM BMW DEALERS SO I HAVE TO SPEND MY OWN MONEY TO FIX THE ISSUE WHICH SHOULD BE TAKEN CARE UNDER RECALL MENTIONED IN THE BEGINNING. MY VEHICLE IS WITH THE MECHANIC AND IT SHOWS THE LEAK FROM VACUUM PUMP WHICH CAN CREATE SERIOUS ACCIDENT WHILE DRIVING. I DONT WANT TO TAKE ANY RISK DRIVING VEHICLE IN A CONDITION WHEN BRAKES WONT APPLY, SPECIALLY HAVING KIDS IN MY CAR. MY CAR BROKE DOWN BECAUSE ALTERNATOR GENERATED HIGH VOLTAGE WHICH SCREWED UP MY BATTERY SO I GAVE MY CAR TO CERTIFIED MECHANIC TO FIX IT. WHILE FIXING THE MENTIONED ISSUE, HE FIND OUT OIL LEAK FROM VACUUM PUMP. I DID RESEARCH ABOUT THIS ISSUE AND FIND OUT THAT PEOPLE GOT LUCKY THAT THEY GOT SAVED IN ACCIDENTS DUE TO OIL LEAK IN VACUUM PUMP THAT'S WHAT MADE ME SCARED. *JS

BRAKE LINES CORRODED AND RUPTURED WITH LOSS OF BRAKE FLUID AND DECREASED BRAKING ABILITY. BRAKE LIGHT CAME ON AFTER GENTLE BRAKING ON THE ROAD AT LOW SPEED.

THE POWER BRAKING SYSTEM HAS STOPPED WORK ,BRAKE PEDAL GOES TO THE FLOOR AND WILL NOT STOP THE VEHICLE ,I SEE THAT BMW HAS A RECALL ON THE 2007 X5 MADE THE SAME YEAR AND MODEL WITH THE V8 ENGINE, I AM A MEMBER ON MY FORMS AND THERE ARE HUNDREDS OF BMW X5 WITH THE SAME PROBLEM, AND SOME PEOPLE HAVE HAD ACCIDENTS BECAUSE OF THE BRAKING SYSTEM SUDDENLY NOT WORKING , I HAD MY BMW X5 AT THE BMW SHOP AND THEY DIAGNOSE WAS THE VACUUM PUMP HAS FAILED , VACUUM TUBE IS LEAKING AND THE BRAKE BOOSTER HAS FAILED ALSO. THIS IS A SERIOUS PROBLEM , THIS IS NOT A TAIL LIGHT NOT WORKING , THIS IS PUTTING PEOPLE LIVES IN DANGER. THE REPAIR COST IS $2300.

THE ISSUE IS SPECIFICALLY WITH THE BRAKING SYSTEM. THE CAR DEVELOPED A SUDDEN DANGEROUS LOSS OF BRAKING POWER. ONE MOMENT THE BRAKES WERE WORKING CORRECTLY AND THE NEXT THEY WERE NOT. BMW HAS 2 RECALLS FOR THIS ISSUE BUT FOR UNKNOWN REASONS MY CAR IS NOT INCLUDED IN EITHER RECALL. THE RECALL CAMPAIGNS ARE 10V-446 & 13V-045. THE DESCRIPTION OF THE PROBLEM IS THE FOLLOWING: "THIS RECALL INVOLVES THE POWER ASSIST BRAKING FUNCTION. A SMALL AMOUNT OF OIL COULD LEAK FROM THE BRAKE VACUUM PUMP INTO THE BRAKE VACUUM HOSE. OVER TIME, CONTAMINATION OF THE BRAKE BOOSTER COULD OCCUR. THIS COULD AFFECT THE POWER ASSIST BRAKING FUNCTION. IN CERTAIN CASES, LOSS OF POWER BRAKE ASSIST COULD OCCUR. IF THIS HAPPENED, IT WOULD REQUIRE GREATER BRAKE PEDAL FORCE, INCREASE THE STOPPING DISTANCE, AND INCREASE THE RISK OF A CRASH. " MY CAR HAS THE EXACT ISSUE AS DESCRIBED IN THE RECALLS. THERE IS NO WARNING LIGHT TO INDICATE THERE ARE ANY ISSUES WITH THE BRAKES. I CALLED BMW NA AND DESCRIBED THE ISSUE TO THEM AND THEY TOLD ME TO TAKE IT TO MY LOCAL BMW DEALERSHIP TO HAVE THE ISSUE DIAGNOSED. THE LOCAL DEALERSHIP DETERMINED MY CAR HAD THE ISSUE AS DETAILED IN BOTH BMW RECALLS. AS INSTRUCTED BY BMW I REPORTED THIS BACK TO THEM AND AFTER SEVERAL WEEKS THEY FOLLOWED UP WITH ME (2/10/15 TO BE EXACT) ONLY TO TELL ME THEY WILL NOT FIX THE ISSUE AS PART OF THE RECALL AND THUS I WOULD HAVE TO PAY FOR IT OUT OF MY OWN POCKET. THIS DECISION WAS MADE DESPITE THE FACT THAT MY CAR MEETS NEARLY ALL PARAMETERS OF THE RECALLS (MY EXACT MODEL IS NOT LISTED AS PART OF THE RECALL BUT THE MODEL OF BRAKING SYSTEM AND ENGINE MATCHES THE RECALL DETAILS). THIS IS A SERIOUS SAFETY ISSUE AND ONE THAT I DO NOT BELIEVE BMW SHOULD BE OVERLOOKING OR DENYING COVERAGE FOR. THIS BRAKE ISSUE AFFECTS MORE THAN JUST THE CARS LISTED IN THE TWO BMW RECALLS.

TOOK IT BACK FOR CHECK AND IT WAS DETERMINED THAT LINE HAD ROTTED THROUGH. HARD TO UNDERSTAND THIS WAS IN ENCLOSED PROTECTED AREA. *TR

TL* THE CONTACT OWNS A 2006 BMW X5. THE CONTACT STATED THAT WHILE AT A TRAFFIC LIGHT, THE BRAKES FAILED TO RESPOND. THE PROBLEM RECURRED NUMEROUS TIMES. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC. THE TECHNICIAN DIAGNOSED THAT THE BRAKE BOOSTER NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED ABOUT THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 85,000.

WHILE SITTING AT A RED LIGHT THE BRAKE PEDAL ALL OF SUDDEN BECAME HARD AND APPLIED A UNREASONABLE AMOUNT OF PRESSURE AGAINST MY LEG. IN ORDER TO MAKE THE CAR STOP I NEEDED TO EXERT A TREMENDOUS AMOUNT OF PRESSURE IN ORDER TO STOP THE CAR FROM ROLLING FORWARD AND HITTING THE CAR IN FRONT OF ME. THERE HAS BEEN A RECALL FOR THE 2007 AND NEWER 8 CYL X5 BRAKE BOOSTERS. OBVIOUSLY THIS IS THE SAME PROBLEM AND THERE SHOULD BE A RECALL DONE WITH THIS CAR AS WELL. ANY DENIAL ON THE PART OF BMW THAT THIS IS A PRODUCT DEFECT IS A DENIAL ON THEIR PART. *TR

THE BRAKES FAILED WHILE I WAS DRIVING TO WORK. I STEPPED ON THE BRAKES TO STOP FROM APPROXIMATELY 30MPH AND THE VEHICLE DID NOT SLOW DOWN OR COME TO A STOP. I HAD TO STEER ONTO THE MEDIAN TO AVOID HITTING THE VEHICLE IN FRONT OF ME. MECHANIC SAID THE BOOSTER NEEDS TO BE REPLACED. NO WARNINGS DISPLAYED IN DASHBOARD. EXTREMELY DANGEROUS AND I'M LUCKY TO HAVE AVOIDED A MORE SERIOUS ACCIDENT. SOMEONE COULD HAVE BEEN SERIOUSLY HURT GIVEN THE SIZE OF THIS VEHICLE. *TR

MY X5 4.4 BEGAN TO HAVE A HARDER AND HARDER BRAKE PEDAL. IN A THREE WEEK PERIOD IT WENT FROM A LITTLE HARD AT THE END OF THE STOP TO ABSOLUTELY NO BRAKES. WHAT IS MORE CONCERNING IS THAT MY MOTHER-IN-LAW ALSO HAS A 2006 X5 4.4 THAT THE SAME EXACT THING HAS HAPPENED AND SHE HAS HALF THE MILES. THIS APPEARS TO BE A WORKMANSHIP OR DESIGN FAULT SINCE IT IS NOT MILEAGE DEPENDENT BUT AGE. IT IS AN ABSOLUTE SAFETY CONCERN SINCE THE BRAKES WILL COMPLETELY FAIL SHORTLY AFTER THE 1ST INDICATION. BMW HAS A HISTORY OF SKATING ON RECALLS, THE SAME PROBLEM HAPPENS TO 5 SERIES USING THE SAME SET UP AND IT WAS RECALLED. *TR
