2012 BMW 6 Series

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.

BMW GROUP ISSUED VOLUNTARY RECALL NO. 18V-248: ELECTRONIC AUXILIARY WATER PUMP FAILURE. PRIOR TO RECEIVING A RECALL NOTICE BY MAIL, MY CAR'S INSTRUMENT PANEL REGISTERED THE FOLLOWING MESSAGE WHILE DRIVING AND ON COLD STARTUP: "ENGINE TEMPERATURE HIGH, DRIVE MODERATELY..." . THE TEMPERATURE GAUGE READ NORMAL BEFORE, DURING, AND AFTER THE WARNING MESSAGE DISPLAYED (BOTH STATIONARY AND WHILE DRIVING). THE BMW SERVICE CENTER INFORMED ME THE MESSAGE WAS DUE TO THE RECALLED AUXILIARY WATER PUMP FAILURE, 18V-248. IN ADDITION, THE TURBO COOLANT LINES WERE FOUND TO BE LEAKING WHICH THE SERVICE CENTER INFORMED ME WERE NOT COVERED BY THE RECALL. IT SEEMS A FAULTY AUXILIARY WATER PUMP WOULD CAUSE OR INCREASE THE LIKELIHOOD OF FAILING TURBO COOLANT LINES. IN ADDITION, A FAILING CIRCUIT BOARD COULD RENDER OTHER ELECTRICAL FAILURES IN THE VEHICLE THAT BMW IS NOT ACKNOWLEDGING IN THIS RECALL. I REQUEST NHTSA INVESTIGATE AND COMPEL BMW GROUP TO EXPAND ON THIS RECALL.

TL* THE CONTACT OWNS A 2012 BMW 650I. THE CONTACT WAS DRIVING 70 MPH, IN A THUNDERSTORM IN THE LEFT LANE OF THE INTERSTATE, WHEN HE NOTICED A BOLT OF LIGHTING LAND JUST TO THE RIGHT OF THE INTERSTATE IN THE GRASS. 31 OF 43 ELECTRICAL MODULES FAILED IMMEDIATELY, INCLUDING THE ENGINE, STEERING, BRAKES, RADIO AND THE DASHBOARD. THE VEHICLE COULDN'T BE RE-STARTED, OR EVEN SHIFTED INTO TO NEUTRAL. THE VEHICLE WAS AT THE BMW DEALERSHIP FOR 105 DAYS, WITHOUT INTERRUPTION. NONE OF THE REPLACED PARTS EXHIBITED ANY PHYSICAL STIGMATA OF HIGH VOLTAGE ELECTRICAL DAMAGE AND THERE WAS NO BURNING, SCORCHING, OR MELTING EVIDENT ON ANY OF THE PRINTED CIRCUIT BOARDS INSIDE THE REPLACED COMPONENTS. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE, BUT ASSERTED THAT THE BMW WARRANTY DID NOT COVER MALFUNCTIONS RELATED TO ENVIRONMENTAL INFLUENCES SUCH AS THUNDERSTORMS. THE FAILURE MILEAGE WAS 2,345.

The basic conditions for initializing the power windows are not met.

The electrical system of BMW vehicles has been subject to an ongoing development process over the last few years. This has led to increased demands being placed on the battery. This document covers important information for the dealer on how to handle “discharged battery” complaints.
