2013 BMW 335IS

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.

"TAKATA RECALL. TOOK BMW TO BMW DEALER ON MALLORY ROAD IN NASHVILLE TN ON NOV. 3 TO HAVE AIRBAG REPLACED AT 10:00, MY APPOINTMENT TIME. VEHICLE WAS RETURNED TO ME ABOUT ONE HOUR LATER. BMW REFUSED TO GIVE ME ANY PAPERWORK RELATED TO THE MY VISIT. THIS SUGGEST THEY DID NOT CHANGE THE BAG. PLEASE TELL BMW TO PROVIDE ME WITH THE COMPLETED WORK ORDER SO I HAVE PROOF THE BAG WAS REPLACED

AS PER BMW, 5140 READ FAULT MEMORY, CONNECTED BATTERY CHARGER FAULT CODE 2A9A,31002A9B, RAN TEST PLAN, UPON INSPECTION, NOTED FRONT BOLT HAD BEEN PULLED FREE AND THREADS STRIPPED, THIS COMMON WITH AN ENGINE OVER REV.(DAMAGING INTERNAL ENGINE COMPONENTS . THIS WAS LATER CONFIRMED THROUGH DIAGNOSTIC READOUTS PERFORMED BY BMWNA TSE VIA COMPUTER. AS PER BMW TECHNICAL SUPPORT ENGINEER, DISASSEMBLE AND REASSEMBLED COMPLETE ENGINE TO INSPECT DAMAGE, ALL EXHAUST VALVE HIT THE TOP OF THE PISTONS, CRANKSHAFT TREAD ARE STRIPPED OUT ALONG WITH THE CENTER BOLT. METAL GOT INTO ENGINE BLOCK WHICH WILL RESULT IN FURTHER ENGINE PROBLEM WITH OIL PASSAGES AND OIL PUMP. RECOMMEND COMPLETE ENGINE. CUS DECIDED TO NOT PROCEED WITH REPAIR. BMW IS MAIL ATTACHMENTS. **CUSTOMER GOODWILL DIAGNOSIS COURTESY OF DCH MIDLAND DIAGNOSIS APPROVED BY BMW TSE** NO REPAIR PERFORMED AS PER CUSTOMER NECESSARY REPAIRS NOT COVERED UNDER BMW WARRANTY AS VEHICLE WAS OVER REVVED... CAR IS BRAND NEW 2013 WITH 5,140 MILES 335IS. I HAVE BEEN WORKING THIS ONE AROUND IN MY HEAD AND I CAN'T SEEM TO COME UP WITH ANYTHING... CRANK BOLTS JUST DON'T LOOSEN BY THEMSELVES AND EVEN STILL, THE COMPUTER RECORDED AN OVER-REV EVENT WHICH YOU CAN'T JUST "DO". YOU HAVE TO MECHANICALLY FORCE AN OVER-REV, AND EVEN TILL, THE DME RECORDS TIME SINCE THE EVENT HAPPENED, SO IF IT HAPPENED MONTHS AGO, IT SHOULD BE RECORDED THAT WAY (IF IT EVEN RECORDS THAT FAR BACK). *TR

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.

Diagnosis of Compound Brake System Complaints in M Vehicles: 1. Visible cracks are caused by high thermal stresses during rapid heating and cooling of the brake discs. Braking from high speed with cold brake components (less than 212 degrees F) increases the likelihood of cracks to form.
