MY ISSUE: ONE MORNING I STARTED MY CAR TO LEAVE FOR WORK. WHEN IDLING IT FELT A LITTLE ROUGH BUT STOPPED AFTER JUST A MINUTE OR TWO. THE NEXT DAY IT ALSO WAS ROUGH BUT ESCALATED TO A SHAKING AND THE CHECK ENGINE & THE SERVICE ENGINE SOON LIGHT BOTH CAME ON. I TOOK IT TO A EUROPEAN AUTO MECHANIC TO HAVE IT CHECKED OUT. THEIR CODE READER SAID THERE WERE TWO CYLINDERS MISFIRING. WHAT THEY TOLD ME IS THERE IS NO WAY AT 52K MILES THERE ARE BAD INJECTORS, IT MUST BE THE GAS STATION I HAD USED. THEY RECOMMENDED I RUN A TAKE OF GAS FROM A CHEVRON OR SHELL AND ALL SHOULD BE GOOD. THAT IS WHAT I DID. THE PROBLEM PERSISTED. I THEN TOOK IT TO THE SERVICE CENTER AT CHAPMAN BMW ON CAMELBACK IN PHOENIX. I LEFT MY CAR THERE ON A FRIDAY AFTERNOON (LUCKILY THERE ARE COURTESY VEHICLES), I GOT A CALL MONDAY FROM MY SERVICE ADVISOR. HE LET ME KNOW THAT I HAVE 4 BAD INJECTORS BUT RECOMMENDS TO REPLACE ALL 6 BECAUSE THERE HAS BEEN AN UPDATED INJECTOR FOR THIS ENGINE. HE ALSO INFORMED ME THAT THERE WAS PREVIOUSLY A RECALL FOR THE INJECTORS IN THIS ENGINE THAT INCLUDED ONLY SELECT CARS. MINE WAS APPARENTLY NOT ONE OF THEM. I WAS WITHOUT MY CAR FOR 5 DAYS AND I HAD TO PAY $2,106.10 TO REPLACE INJECTORS ON A CAR WITH ONLY 52 THOUSAND MILES. FROM WHAT I KNOW AND HAVE HEARD ABOUT BMW, THE INJECTORS SHOULD NOT BE AN ISSUE UNTIL AT LEAST THE 100K MILE MARK. MY QUESTION IS, HOW IS IT ETHICAL FOR A COMPANY CAN MAKE A CUSTOMER PAY $2100 ON A REPAIR THAT THEY KNOW IS AN ISSUE? IF IT WASN'T AN ISSUE THERE WOULD NOT HAVE BEEN A RECALL ON SOME CARS. THE FACT THAT MY CAR IS ONLY 2 THOUSAND MILES OUT OF WARRANTY ADDS TO THE FRUSTRATION, CLEARLY, MINE SHOULD HAVE BEEN INCLUDED IN THE RECALL. *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.

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.
