I WAS INFORMED BY AN INDEPENDENT BMW REPAIR SHOP THAT THE REAR SPRINGS WERE BROKEN. A SUBSEQUENT VISIT TO A BMW DEALER CONFIRMED THIS. I WAS ALSO INFORMED BY BOTH THE INDEPENDENT SHOP AND THE DEALER THAT THIS WAS A COMMON PROBLEM WITH 3 SERIES BMWS. BMW OF NORTH AMERICA TOLD ME THAT THIS WAS NOT AN ITEM THAT WOULD BE COVERED UNDER THEIR CPO WARRANTY OR ANY OTHER WARRANTY. I WOULD THINK THAT BROKEN SPRINGS WOULD AFFECT HANDLING AND THEREFORE CONSTITUTE A SAFETY HAZARD. BOTH THE DEALER AND INDEPENDENT SHOP STRONGLY RECOMMENDED THAT I HAVE THEM REPLACED AS SOON AS POSSIBLE. *TR

PASSENGER SEAT ALARM WOULD ACTIVATE FOR NO APPARENT REASON ON A DAILY USE. UNDER WARRANTY SEAT PAD WAS REPLACED. REPORTED SAME SEAT MALFUNCTION ONE MONTH AFTER WARRANTY RAN OUT AND BMW AGREED TO PAY FOR SEAT PAD AND I WOULD HAVE TO PAY FOR LABOR OF $300.00. AT THIS TIME SEAT NO LONGER SOUNDING ALARM. SEAT ALARM WOULD MALFUNCTION AGAIN THE ENTIRE HOT WEATHER SEASON OF 2013. AFTER CONTACTING BMW IN DEC OF 2013 I WAS TOLD NO COVERAGE. AFTER RESEARCHING INTERNET I DISCOVERED THIS TO BE A REGULAR COMPLAINT SINCE 2003 WHEN 1ST X3 WAS MANUFACTURED. I DISCOVERED LAST WEEK THAT AS LONG AS THIS PAD IS NOT FUNCTIONING PROPERLY THE AIR BAG MAY NOT WORK IN AN ACCIDENT. THIS A VERY SERIOUS DRIVING SITUATION THAT COULD RESULT IN SERIOUS INJURY. BMW NEEDS TO BE HELD ACCOUNTABLE AND MADE TO ADDRESS THIS SAFETY HAZARD IMMEDIATELY. *TR

SERVICE ENGINE SOON LIGHT CAME ON. DIAGNOSED AT DEALERSHIP THAT IT WAS THE DMTL PUMP THAT SENSES AND GAS LEAKS. I WAS TOLD BY SERVICE MANAGER THAT IT WAS OUT OF WARRANTY AND I DIDN'T HAVE TO REPLACE IT SINCE I LIVED IN PA IN AN AREA THAT DIDN'T REQUIRE IT TO WORK UNDER OUR STATE INSPECTIONS. THE ONLY PROBLEM WAS THAT THE SERVICE ENGINE LIGHT WOULD BE ON AND I WOULD NOT KNOW IF SOMETHING ELSE WAS WRONG WITH THE CAR. LATER I WAS TALKING TO SERVICE MANAGER AT LEXUS WHO WAS A FORMER BMW SERVICE MANAGER WHO STATED IT WAS COVERED UNDER PA EMISSION LAWS. I CONTACTED MANAGER AT BMW WHO INFORMED ME THAT I WOULD HAVE TO CONTACT BMW. I REGISTERED A COMPLAINT WITH BMW WHO CAME BACK 3 WEEKS LATER DENYING ANY COVERAGE. WHEN ASKED WHY GENTLEMAN COULD NOT ANSWER STATING HE WAS NOT A TECHNICIAN. I REPEATEDLY STATED FROM MY RESEARCH THAT PA ADOPTED CALIFORNIA EMISSION LAW IN 1996 AND FROM MY UNDERSTANDING IT SHOULD BE REPLACED BY BMW. ONCE AGAIN I WAS TOLD NO COVERAGE AND I ASKED IF HIS 3 WEEKS OF RESEARCH INVOLVED A CORPORATE ATTORNEY. HE WOULD NOT ANSWER.IT APPEARS THAT A BMW BUYER IS GIVEN 4 YEAR WARRANTY BECAUSE AFTER THAT EVERYTHING IS DENIED WITH NO EXPLANATION AS TO WHY. THIS DMTL PUMP IS A SENSOR FOR FUEL LEAKS AND COULD REALLY CAUSE A SERIOUS ACCIDENT IF NOT REPLACED. I BELIEVE PA EMISSION LAWS UNDERSTAND THE HAZARD AND THAT IS WHY THEY STATE IT SHOULD BE REPLACED. THIS PROBLEM WITH BMW GOES BACK OVER 10 YEARS ACCORDING TO INTERNET FORUMS.. I CANNOT UNDERSTAND WHY THEY HAVE NOT BEEN HELD ACCOUNTABLE AND MADE TO CORRECT THIS HAZARDOUS SITUATION. *TR

PASSENGER SEAT ALARM WOULD GO OFF CONSTANTLY WITHOUT ANYONE OR ANYTHING IN THE SEAT. BMW REPLACED SENSOR UNDER WARRANTY. PROBLEM APPEARED TO BE FIXED UNTIL THE FOLLOWING SUMMER 2012 WHEN ALARM ON SEAT WOULD GO OFF AGAIN ON A REGULAR BASIS. BMW REFUSED TO REPLACE UNTIL COMPLAINT FILED AND I STATED IT WAS A DRIVING HAZARD DUE TO ATTEMPTING TO FUMBLE WITH BELT WHILE DRIVING TO STOP ALARM BY SECURING BELT. BMW OFFERED TO REPLACE ALARM SENSOR I HAD TO PAY $300.00 FOR LABOR. THIS WAS LATE SEPT 2012. SHORTLY AFTER DUE TO COLD WEATHER ALARM DID NOT GO OFF ANY LONGER.I DID NOT HAVE ALARM SENSOR REPLACED BECAUSE IT WAS NOW WORKING PROPERLY UNTIL APRIL OF 2014 WHEN ALARM AGAIN BEGAN TO SOUND AND CONTINUED THROUGHOUT THIS PAST SUMMER. ACCORDING TO INTERNET AND FORUMS ON THE INTERNET THIS IS A PROBLEM THAT HAS EXISTED ON X3S FROM THE FIRST YEAR THE CAR WAS SOLD. BMW APPARENTLY AVOIDS DOING ANYTHING TO PREVENT THIS FROM OCCURRING EVEN IN THE NEWER MODELS.THIS IS AN ANNOYING AND DANGEROUS SITUATION WHICH SHOULD BE ADDRESSED .IN MY COMPLAINT THEY STATED I DIDN'T ACCEPT THEIR OFFER EVEN THOUGH THE ALARM WAS NO LONGER GOING OFF AND THAT MY WARRANTY WAS OVER.

I WAS TOLD THAT ALL 4 ALUMINUM SUPPORT BOLTS HAD BEEN SHEARED AND THAT THE ENGINE WAS RESTING ON THE WATER PUMP CAUSING THE LEAK. THE SOLUTION, WHILE COVERED BY MY EXTENDED WARRANTY, IS STILL COSTING ME $50 DEDUCTIBLE AND ANOTHER $200 OR SO TO FLUSH AND REPLACE THE COOLANT (WHICH WAS CAUSED BY THE WATER PUMP DAMAGE). IF I DIDN'T HAVE THE WARRANTY AND WAS FORCED TO PAY FOR THE LABOR, BOLTS, SUPPORT BRACKETS AND A WATER PUMP - I WOULD BE EVEN MORE IRATE THAT BMW HASN'T ISSUED A RECALL ON THIS WELL KNOWN ISSUE. *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.
