MY WIFE & I PURCHASED THIS 2012X5 2 YEARS AGO,LAST YEAR THE VEHICLE WAS BEING DRIVEN OFF THE DRIVEWAY WHERE THERE WAS A LOUD SNAP&BAN. THE CAR DIDN'T MOVE. WE CALLED A TOW AND HAD IT BROUGHT TO JUPITER BMW FL .WE FOUND OUT THAT THE DRIVE SHAFT SNAPPED. MILEAGE WAS 45-48K MILES. WE CALLED BMW NA IT WAS A WARRANTY RECALL PART AND THE DEALER STATED IT WAS REPLACED. AFTER THAT IN THE LAST 10 MONTHS WE HAVE EXPERIENCED MANY STRANGE MOVEMENTS IN THE REAR AND IN TURNS. WE CALLED THE DEALERSHIP AND SPOKE TO A TECH WHERE THEY STATED IT WAS TIRES IN THE REAR. WE RECENTLY REPLACED THE TIRES & IT REMAINED TO BE THERE WHERE IT WAS MILD BUT THERE. DURING THIS TIME PERIOD WE HAD MANY SERIOUS OBSTACLES WITH CANCER & FAMILY IN PR DEVASTATED. WE RECEIVED A RECALL NOTICE AIRBAG, WE CALLED THE DEALER TO REPLACE IT. WHILE THERE WE FAILED TO MENTION IT BEING IN A RUSH & STILL ONLY ONE OF THE TWO AIRBAGS STILL UNAVAILABLE. AFTER WE LEFT DURING THE MONTH WE FELT IT MORE SO, AT THAT TIME I TRY TO REACH THE SERVICE ADVISOR & FAILED TO REACH HER IN SEVERAL ATTEMPTS. AFTER DRIVING THIS WEEK IT GOT SERIOUSLY WORSE WHILE MY FAMILY LITTLE CHILDREN IN CAR, WE PULLED OVER CALLED OUR LOCAL MECHANIC AND HE SAID BRING IT IF POSSIBLE OR TOW.SO WE DID! AT THAT TIME WE NEVER DISCUSSED WE REPLACED ANY RECALL DRIVE SHAFT (MAKE NOTE). THE MECHANIC CALLED US IN SHOP SAID THE SHAFT IS BROKE AND LEAKING GREASE HAS A LOT OF PLAY IN IT, ALSO DO TO THAT IS DIRECTLY RELATED & CAUSE TO BE A ISSUE WITH TRANSFER CASE!!!. WE TOOK A VIDEO OF IT AND THE MECHANIC & US CALLED BMW NA DISCUSSED IT & THEY RECOMMEND TO TAKE TO BMW UNDER EXTENDED WARRANTY. UPON ARRIVAL WE PROVIDED THE SERVICE TECH A VIDEO OF THE DISCOVERY .6 HOURS LATER THEY CLAIM THE SHAFT IS FINE & VIDEO & INSPECTION WAS NOT ISSUE, &TRANSFER CASE HAVING ISSUES. THEY SAID OUR BILL 9000$.THERE IS OVER 300 CLAIMS EXACT ISSUE #17V138000SEE ATTACHED PIC & COMPL

TRANSFER CASE PROBLEM. BOUGHT THE CAR NEW, AFTER THE 2ND YEAR FELT VIBRATION /SHUDDERS WHEN MAKING TURNS FROM A STOP OR LOW SPEED. DEALER REPLACED FRONT BRAKE ROTORS, CHANGED FRONT WHEELS. STILL SAME ISSUE END UP CHANGING 4 NEW TYRES AFTER A YEAR. UP UNTIL 2016 CHANGED AGAIN FRONT AND REAR BRAKE WHOLE SYSTEMS, FRONT DRIVE SHAFT REPLACED DUE TO SAFETY RECALL LAST JULY BUT STILL THE VIBRATION/SHUDDERS REMAINS. SERVICE ADVISOR TOLD ME IT COULD BE THE TRANSFER CASE AS IT IS MOST ISSUES THEY RECEIVED. QUOTED ME FOR $2650. TOLD HIM THAT MY EXTENDED WARRANTY EXPIRED 2016. THE FACT THAT THE SAME EXACT PROBLEM WAS ALREADY REPORTED TO THEM EARLY ON AND NOW I'VE BEEN ASKED TO PAY FOR THAT LONG OUTSTANDING PROBLEM. VERY DISAPPOINTED. WENT TO TWO DIFFERENT DEALER; TENAFLY UNDER PENSKE GROUP WHERE I BOUGHT THE CAR EVEN QUOTED ME FOR $8000; REACHED OUT TO BMW DIRECT US RECALL SERVICE AND WILLING TO PAY HALF SO IT'LL END UP STILL FOR $4000. BMW HACKENSACK UNDER PARK AVE GROUP QUOTED ME FOR $2650 PARTS AND LABOR EXCLUDING TAX. REALLY VERY DISAPPOINTED AFTER SPENDING/INVESTING A LOT OF MONEY TO THE CAR. HOPE BMW ISSUE A SAFETY RECALL ESPECIALLY I'VE BEEN SEEING A LOT AND SAME PROBLEMS WITH THE TRANSFER CASE IN X5. JUST LOOK ONLINE AND YOU'LL SEE A MANY COMPLAINTS. I'M SURE BMW SEES HOW MANY TRANSFER CASES THEY BEEN REPLACING UNDER THE WARRANTY OR THEY PROBABLY WON'T EVEN BOTHER THEIR OVERHEAD EXPENSE ESPECIALLY IT'S BEING PAID OFF BUY OTHER CONSUMER/OWNER WHO ENDS UP PAYING THE COST OUT OF WARRANTY, CONSIDERING THEY DON'T HAVE A FIX OR STANDARD PRICES. PRETTY SURE IF I GO TO OTHER DEALER, THEY'LL QUOTE ME DIFFERENTLY.

MY WIFE WAS DRIVING MY VEHICLE TO GET CAR WASH. ALL OF A SUDDEN SHE LOST POWER STEERING AND THE CAR BATTERY WARNING CAME ON. THE IDLER PULLEY BOLT SNAPPED. LUCKILY MY WIFE DID NOT CRASH. SHE WAS DRIVING 60MPH AND LOST POWER STEERING. SHE IS PREGNANT AND HAD 2 KIDS IN CAR. NOW I'VE REPLACED THIS BOLT AGAIN. I PUT PURCHASED A NEW IDLER PULLEY BOLT WITH LOC TITE. I REPLACED IT AND MET EVERY SPECIFICATION THAT NHTSA REQUIRED. BASICALLY IT ONLY REQUIRE MORE TORQUE AND LOC TITE. THIS TIME IT SNAPPED IN MY DRIVE WAY THANK GOODNESS. THIS IS A SERIOUS TRAFFIC SAFETY SITUATION, I'VE READ MULTIPLE FORUMS WHERE PEOPLE HAVE HAD WORK DONE AT DEALERSHIP AND THE BOLT IS SNAPPING 3 DAYS LATER. OBVIOUSLY BMW DID NOT FIX THE PROBLEM.

DRIVESHAFT FAILURE. I WAS DRIVING DOWN THE INTERSTATE ON A STRAIGHT AND LEVEL SECTION OF THE ROAD. I HEARD A LOUD HUMMING FROM THE ENGINE AREA SO I SLOWED DOWN AND THEN I HEARD A LOUD POP AND METAL GRINDING AND HITTING UNDER THE CAR. MY VEHICLE IS OUT OF WARRANTY, SO I HAD IT TOWED TO MY INDEPENDENT MECHANIC THAT SPECIALIZES IN EUROPEAN VEHICLES. THEY SAID THE DRIVESHAFT "FELL APART" AND AS I WAS SLOWING DOWN IT WAS STILL SPINNING AND BANGED AROUND CAUSING DAMAGE TO MY EXHAUST SYSTEM AND OIL PAN. I RESEARCHED AND FOUND THAT 2011 VEHICLES HAD BEEN RECALLED FOR A DEFECT THAT COULD CAUSE THE DRIVESHAFT TO FAIL, SO I CALLED BMW AND THEY TOLD ME THAT SINCE MY VEHICLE WAS NOT LISTED ON THE RECALL THAT THERE WAS NOTHING THEY COULD DO. I TRIED CALLING THEM AGAIN IN REGARDS TO THE PRIOR YEAR'S RECALL AND ASKED IF IT MAY INCLUDE 2012 MODEL VEHICLES AT A LATER DATE AND THEY COULD NOT GIVE ME AN ANSWER. IT SEEMS STRANGE THAT A VEHICLE MANUFACTURED 4 MONTHS AFTER A RECALL HAS THE SAME ISSUE BUT SOMEHOW IT IS NOT COVERED. I CALLED MY LOCAL BMW SERVICE CENTER AND THEY TOLD ME THAT THEY ADDED A 10 YEAR WARRANTY ONTO THE DRIVESHAFT PARTS, BUT I MUST NOT HAVE BEEN NOTIFIED. SO IF I WOULD HAVE TAKEN IT TO THEM, THEY WOULD HAVE FIXED IT FOR FREE, BUT SINCE I DIDN'T, THEY COULDN'T DO ANYTHING FOR ME. THE NHTSA CAMPAIGN # FOR THE 2011 X5 IS: 16V311000. *TR

PURCHASED NEW 2012 X 5 IN AUGUST 2011. IN JULY 2014 CAR VIBRATED ON TURNS IN STEERING COLUMN AND THOUGHT IS WAS THE NEW TIRES, THEY SAID IT WAS THE CIRCUMFERENCE ON ONE OF THE TIRES, INSTALLED NEW SET. STILL THE VIBRATION OCCURRED....TURNS OUT IS TRANSFER CASE AND $6200.00. THEY COVERED ALL BUT 1300.00 OF MINE AT THE DEALER LEVEL. FRIEND BOUGHT SAME VEHICLE IN OCTOBER 2011 SAME DEALER AND I EXPLAINED PROBLEM TO HER AND SHE HAD THE SAME SYMPTOMS AND ALMOST IDENTICAL MILEAGE. HER TRANSFER CASE ALSO BAD THE SAME MONTH MINE WAS. SHE HAD TO FIGHT WITH BMW BECAUSE SHE HAD OVER 75,000. AT FIRST HER ASSISTANCE ON THE REPLACEMENT WAS DENIED, THEN AFTER CALLS SHE ACTUALLY HAD ALL BUT 500.00ISH PAID. DEALER SAID THEY RARELY HAD TO REPLACE A TRANSFER CASE AND IT WAS A FLUKE- WE DIDN'T THINK SO. FAST FORWARD, BOTH CARS NOW 10,000 MILES LATER EACH ( NOVEMBER 2014)"SMOKE" UPON STARTING IF THEY SIT FOR A FEW DAYS (THE "STEAM" CLOUD IS HUGE). WE BOTH HAD TO ADD OIL WHICH THEY SAY IS NORMAL AFTER AN OIL CHANGE LESS THAN 7000 MILES AGO. DEALER SAYS IT IS NORMAL ON THE OIL ADDITION AND NORMAL SMOKE- CONDENSATION- THIS TIME WE TOOK THEM IN THE SAME DAY AND HAD THEM SIT OVER THE WEEKEND. PEOPLE JUMP BACK FROM MINE BECAUSE THEY ARE SCARED! NOW A WEEK LATER, BOTH SMELL OF ANTIFREEZE WHEN LEFT RUNNING A FEW MINUTES PARKED WITH THE HEAT ON. TOO MANY COINCIDENCES. THIS IS MY THIRD BMW- BUT FIRST TIME WITH PROBLEMS. JUST READ ONLINE ABOUT OTHER TRANSFER CASE ISSUES WITH THAT MODEL YEAR. WE BELIEVE AS THESE MODELS AGE, AND PEOPLE HAVE MORE MILES ( WE ARE BOTH REALTORS SO WE HAVE VERY HIGH MILEAGE) THIS TRANSFER CASE WILL FAIL. I BELIEVE IT IS A FAULTY PART AND NEEDS TO BE RECALLED. AT THE RATE WE DRIVE WE WILL NEED ANOTHER TRANSFER CASE IN 2 YRS. *TR

AFTER REPLACEMENT OF BRAKES ON MY 2012 BMW X5, UPON RETURN, I STARTED TO FEEL A VIBRATION WHILE TURNING IN THE PARKING LOT. AFTER TWO VISITS TO THE DEALERSHIP, I WAS INFORMED THAT THE TRANSFER CASE BOX (ASSOCIATED WITH THE TRANSMISSION) HAS FAILED. THIS OCCURS 5000MILES AFTER THE WARRANTY ON THE TRANSMISSION AND ENGINE EXPIRE. I HAVE DONE A GOOGLE SEARCH ON THIS PART ON X5 MODELS, AND OTHERS HAVE REPORTED SIMILAR EXPERIENCES. THIS INCLUDES REPORTS OF FAULTY PARTS INSTALLED AT THE MANUFACTURE. BMW HAS AGREED TO COVER 60% OF THE REPAIR BILL. THIS SENDS A RED FLAG THAT PERHAPS THE MANUFACTURE IS AWARE OF THE PROBLEM AND SHOULD BE REPAIRING AT THE PROBLEM AT NO COST TO THE CLIENT. *TR

EA21002 · Desiccated Air Bag Inflator Rupture

Opened Sep 17, 2021 · No close date supplied

Status: open (inferred from source dates) · Air Bags:frontal:driver Side:inflator Module; Air Bags:frontal:passenger Side:inflator Module

From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.

RQ18001 · Idler Pulley Bolt Failure

Opened Apr 18, 2018 · Closed Dec 1, 2018

Status: closed (inferred from source dates) · Steering; Steering:hydraulic Power Assist System; Steering:hydraulic Power Assist:hose, Piping, And Connections

In a May 23, 2018 letter, BMW of North America, LLC (BMW) notified the National Highway Traffic Safety Administration (NHTSA) of a safety defect that may result in the loss of power steering assist in certain model year (MY) 2009 through 2013 BMW X5 xDrive35d vehicles (Recall 18V-336). The recall, which affects approximately 33,214 vehicles built from March 12, 2008 through June 27, 2013, corrects the remedy and expands the scope of a prior BMW recall (12V-550) which addressed idle pulley bolt failure in approximately 29,800 MY 2009 through 2012 BMW X5 xDrive35d vehicles built from September 1, 2008 through November 15, 2012. BMW's analysis indicates that due to a number of contributing factors it is possible that the bolt's pre-stressing force could drop to an extent that it results in the bolt becoming loosened over time. A loosening of the bolt could cause additional bending stress on top of the bolt. As a result, the bolt could break. If this were to happen, then a sudden loss of power steering assist could occur.If there were a loss of power steering assist, manual steering capability would be retained, although the effort required to steer the vehicle would be greater, and therefore may increase the risk of crash.ODI's analysis of the complaints it has received from the public (VOQ's) and BMW complaint data submitted in response to the information request letter for RQ18-001 identified a total of 93 unique VIN reports alleging failure of the idler pulley bolt after recall 12V-550 was completed on the vehicle, including 31 VOQ's and 72 BMW consumer complaints (5 complaints received by NHTSA and BMW, 3 unique VIN's submitted multiple complaints to BMW, and 1 unique VIN submitted multiple complaints to NHTSA).BMW is developing a new idler pulley fastening system as the remedy for 18V-336.The remedy is planned to begin in February 2019.Based on BMW's safety recall, this recall query is closed.The 31 VOQ's referenced in this resume are: 10499780, 10559422, 10579534, 10655424, 10661614, 10702323, 10819617, 10903433, 10948014, 10984353, 11002447, 11010667, 11013643, 11041551, 11054759, 11054909, 11066063, 11083479, 11097562, 11098865, 11113332, 11128649, 11130277, 10552773, 10817406, 10937632, 10956710, 11032006, 11042259, 11063010, 11091513.
