JUNCTION BOX FAILURE. I STARTED HAVING ALL TYPES OF RANDOM ELECTRICAL PROBLEMS. WIPERS COME ON AT RANDOM. DOOR LOCKS, BACK WINDOWS, AND TURN SIGNALS WON'T WORK WHEN THIS HAPPENS. I READ THAT THIS ISSUE WAS HAPPENING IN OTHER MODELS, BUT DON'T SEE THAT THE BMW X3 ITSELF WASN'T CALLED OUT. HAD THE ISSUE LOOKED AT BY A MECHANIC AND HE SAID THE STORED CODES WERE FOR MAIN JUNCTION BOX FAILURE OR NO MESSAGE RECEIVED FROM MAIN JUNCTION BOX. IT DOESN'T MATTER IF THE VEHICLE IS STATIONARY OR IN MOTION, ISSUE STILL HAPPENS. SOMETIME WHEN I TURN OFF THE CAR, THE WIPERS ARE STILL GOING. SOMETIMES IF I JUST OPEN THE DOOR, WITHOUT TURNING ON THE CAR, THE WIPERS WILL START TO GO.

IT HAS FIRST CAUSED CHECK ENGINE LIGHT OWN WITH A FAULT CODE, THEN DIFFERENT ELECTRICAL COMPONENTS STARTED AFFECTING INCLUDING LIGHTS, BRAKES , ACCELERATION, PICKUP, SPEED CONTROL WHILE DRIVING . I ALREADY REPAIRED TWICE OUT OF POCKET AS IT WAS A PICKUP AND CHECK ENGINE LIGHT ON ISSUE WITH CODE P2096 WHICH INVOLVES PCV COMPONENTS ASSOCIATED WITH THE RECALL. DUE TO THIS DEFECTIVE COMPONENT I'VE ALREADY SPENT 4000+ IN REPAIRS AND STILL THE CHECK ENGINE LIGHT ON AND I'M DRIVING UNSAFELY AS I DON'T HAVE MONEY TO REPAIR FURTHER. I ALSO HAD TO PUT MY FAMILY ON RISK WITH 2 SMALL KIDS AS THIS SUV WE USE AS A FAMILY CAR. SINCE THE ISSUE IS REPORTED A YEAR AGO AND BMW STILL DIDN'T OFFER ANY FIX INTO PURCHASE A NEW CAR TO SAFEGUARD OURSELVES. I DEMAND BMW TO REFUND ME 100K DUE TO ALL THESE ISSUES CAUSED DUE TO THIS PROBLEM AND OFFERING NO TIMELY FIXES AND CAUSING STRESS AND FINANCIAL FRUSTRATION.

WHILE DRIVING ON AN INTERSTATE ROAD, EXITING A TUNNEL, THE X-3 SUDDENLY, WITHOUT ANY WARNING OR INDICATORS, LOST THE POWER STEERING AND POWER BRAKES. THE ENGINE LOST POWER AND THE DASH BOARD LITE UP WITH A MYRIAD OF WARNINGS THAT MADE NO SENSE. THEN, JUST AS SUDDENLY THE ENTIRE DASH BOARD WENT DARK. THE VEHICLE WAS EXTREMELY DIFFICULT TO STEER AND STOP. SINCE I WAS IN FAST MOVING TRAFFIC, THE SITUATION WAS SCARY TO SAY THE LEAST. I FOUND A PLACE TO PULL OFF AND DID SO. I TURNED THE X-3 OFF. AT RESTART IT SEEMED OK, BUT THE PROBLEM RE-OCCURRED AGAIN. I WAS ABLE TO FINALLY GET TO MY HOUSE. STOPPING AND RE-STARTING SEVERAL TIMES. LOSING ALL POWER, BRAKES, STEERING, ETC AT EACH INSTANCE. VEHICLE WAS PLACED ON A FLAT BED AND TAKEN TO SEWICKLEY BMW THE FOLLOWING DAY. AFTER ALMOST A WEEK, THE CAR WAS RETURNED TO ME. I WAS TOLD IT WAS AN ELECTRICAL ISSUE. EXACTLY 2 WEEKS LATER THE SAME PROBLEMS RE-OCCURRED. AGAIN I WAS ON AN INTERSTATE AND THE LOSE OF CONTROL AT A HIGH RATE OF SPEED COULD HAVE BEEN A CATASTROPHE IF AN INEXPERIENCE DRIVER WAS BEHIND THE WHEEL. THE CAR WAS REPAIRED AGAIN AND THIS TIME MORE WORK WAS DONE. THE DEALER SAID THAT THEY FOUND A BULLETIN FROM BMW THAT EXPLAINED THIS POSSIBILITY. I SAW THE BMW INFO AND IT UNDERSTATED WHAT ACTUALLY COULD OR WOULD OCCUR SHOULD THEIR SYSTEMS FAIL. IN MY OPINION, MY LIFE WAS IN SEVERE JEOPARDY WHEN THE FAILURES OCCURRED AND HAD I NOT BEEN AN EXPERIENCED DRIVER WITH CALM REACTIONS, A FATALITY IS NOT OUT OF THE QUESTION. MY WIFE WILL NO LONGER RIDE IN THE VEHICLE AND I HAVE BEEN TOLD TO GET RID OF IT ASAP. I REPORTED THESE INCIDENTS TO BMW AND QUITE FRANKLY THEY WERE TOTALLY INDIFFERENT TO THE PROBLEM, ONLY SAYING THAT THE VEHICLE IS OUT OF WARRANTY AND THEY HAVE NO OBLIGATION TO DO ANYTHING FOR ME. IN MY OPINION, THIS IS A MAJOR PROBLEM WAITING TO EXPLODE. BMW IS IGNORING THE ISSUE AND SOMEONE WILL DIE

MY VEHICLE SUDDENLY LOST POWER STEERING CONTROL AND A YELLOW WARNING SYMBOL APPEARED ON THE INSTRUMENT PANEL. I EXPERIENCED THE PROBLEM THE FIRST TIME WHILE I MANEUVERED A CORNER. I WAS COMING OUT OF THE TURN AND ACCELERATING WHEN THE STEERING LOCKED UP, AND THE LOSS OF STEERING CONTROL ALMOST CAUSED ME TO CRASH. I TOOK THE CAR IMMEDIATELY TO MURRAY MOTORS (IN DENVER, CO) AND WAS ADVISED THAT THERE WAS SIMPLY A COMPUTER PROGRAMMING "GLITCH" THAT CAME FROM THE FACTORY; THE SERVICE CENTER ADVISED THEY DOWNLOADED NEW SOFTWARE AND THE PROBLEM WAS SOLVED. SOME WEEKS LATER, I AGAIN LOST POWER STEERING SUDDENLY WHILE DRIVING STRAIGHT. I TOOK THE CAR INTO MURRAY MOTORS AGAIN AND STRESSED THE ENORMITY OF MY CONCERN OVER THIS FRIGHTENING PROBLEM. AFTER SOME DAYS, MURRAY MOTORS ADVISED ME THAT THE ELECTRONIC POWER STEERING ASSIST UNIT HAD FAILED. THEY REPRESENTED THEY REPLACED THE POWER STEERING RACK, THE ELECTRIC MOTOR MOUNTED ON THE RACK, AND THE EPS MODULE. I RESEARCHED BMW RECALLS THEREAFTER AND FOUND THAT A RECALL HAD BEEN ISSUED FOR THIS PROBLEM ON SEVERAL BMW MODELS ALREADY. I CALLED BMW'S CUSTOMER RELATIONS NUMBER (1-800-525-7417) AND WAS INFORMED THAT MY VEHICLE VIN NUMBER FELL OUTSIDE THE SCOPE OF THE CURRENT RECALL, AND I WAS THEREFORE NEVER NOTIFIED. I AM WRITING THE NHTSA TO REPORT THAT BMW'S RECALL IS NOT BROAD ENOUGH AS DEFECTS IN THE EPS MODULE AND RELATED PARTS EXIST IN VEHICLES BEYOND THE IMMEDIATE RECALL. I ALSO WANT THE NHTSA TO KNOW THAT MURRAY MOTORS ALLOWED ME TO DRIVE THIS VEHICLE OUT OF THEIR SERVICE CENTER AFTER THE FIRST (INADEQUATE) REPAIR, EVEN THOUGH THE STEERING COMPLAINTS I REPORTED TO THEIR SERVICE TECHNICIANS WERE IDENTICAL THE DESCRIPTION OF THE STEERING PROBLEM LISTED IN BMW'S RECALL LETTER FOR THE X3 POSTED ON THEIR WEBSITE. MURRAY MOTORS CLAIMS TO HAVE NO KNOWLEDGE OF THIS DEFECT IN ANY X3. *TR

1EA21002 · 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.
