I WAS DRIVING ON THE HIGHWAY AND THE CAR WAS READING THAT IT HAD GAS, THEN SUDDENLY IT CAME TO A STOP, ON THE HIGHWAY, THE CAR WAS TOWED TO THE DEALER, AND IT WAS FOUND THAT THE FUEL LEVEL SENSOR HAD DIED MAKING THE CAR THINK IT HAD GAS WHEN IT IN FACT HAD NONE. THE DEALER WANTS TO REPLACE THE ENTIRE TANK FOR $2700, THIS ISSUE IS INCREDIBLY DANGEROUS AS IT CAN LEAVE ANYONE STRANDED ANYWHERE. THIS CAR IS ONLY 6 YEARS OLD AND THIS ISSUE CAN BE FOUND ON BMWS MUCH OLDER THEN THAT. BMW KNOWS ABOUT THE ISSUE, THEY KNOW IT IS DANGEROUS AND THEY CHOOSE TO CONTINUE MAKING CARS WITH THIS IS ISSUE. AS FAR AS I CAN TELL BMW DOES NOT CARE ABOUT THE DRIVERS OF ITS CARS AND ONLY CARES ABOUT MAKING MONEY BY SELLING DEATH TRAPS TO PEOPLE. IF YOU WANT TO BE LEFT STRANDED AND RISK GETTING KILLED ON THE HIGHWAY OR GETTING STRANDED IN THE MIDDLE OF NO WHERE, BY A BMW. IF NOT, BUY A MERC OR AUDI. THIS ISSUE CAN HAPPEN IF THE CAR IS UNDER WARRANTY AS WELL. ANY BMW THAT USES THE GAS TANK FROM THE F30 3 SERIES IS EFFECTED, AS WELL AS BMWS AS FAR BACK AS THE E46. *TR

THIS PROBLEM CONCERNS THE DOOR LATCHES ON THE BMW 335I (F30 GENERATION). THE PROBLEM I HAVE NOTICED IS THAT ONCE IN A WHILE, THE DOOR DOES NOT UNLOCK WHEN PULLING THE LATCH. TYPICALLY, YOU WOULD PULL THE DOOR HANDLE ONCE, UNLOCKING THE CAR, AND ONCE AGAIN TO OPEN THE DOOR. WHEN THIS PROBLEM PRESENTS ITSELF, PULLING ON THE HANDLE DOES NOT UNLOCK THE CAR. ONLY THE ELECTRONIC BUTTON CAN BE USED TO UNLOCK IT. IT PROBLEM COULD CAUSE DANGER IN THE CASE OF AN ACCIDENT WHERE THE ELECTRICAL SYSTEM IS NO LONGER WORKING AND COULD LEAVE ONE TRAPPED INSIDE OF THEIR CAR. THE PROBLEM PRESENTS ITSELF INTERMITTENTLY. I HAVE ONLY NOTICED THE PROBLEM HAPPEN WHEN PARKED. I BELIEVE THAT THE LOCK ACTUATOR IS THE FAULTY COMPONENT HERE. EVEN WHEN USING THE ELECTRONIC BUTTON TO UNLOCK THE DOOR, YOU CAN SEE THAT THE LOCK INDICATOR (THAT SMALL THING ON THE SIDE OF YOUR DOOR) GOES UP MUCH SLOWER THAN THE OTHER UNAFFECTED DOORS. *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.
