2014 BMW 535I

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.

NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.

This is a known and unaddressed issue. BMW headlight seals fail allowing condensation to build and erode electronics. Replacement costs exceed $15K and only OEM parts and BMW servicing are options. Many BMW repair shops refuse to do this work as it is overly complicated and expensive. This issue is well known and document and warrants compensation and/or recall.

LEFT LIGHT IS NOT WORKING. I HAVE TO USE MY BRIGHT LIGHTS TO HAVE LIGHTS AT NIGHT. I HAVE NOTICE THIS ON SEVERAL OTHER BMW'S IN THIS YEAR RANGE 2013-2014. SOMETHING ELECTRICAL IS WRONG WITH THIS LIGHT.

Driver-side headlight started getting condensation last winter. Brought the car to the dealer to see if they can replace the gasket but was told that it needs to be replaced and it could cost as much as $7,000 if the module needs to be replaced as well. That is ridiculous that it needs to be replaced at such ab absurd cost. Lights can stop working if it burns out and dangerous if it occurs at night and lose your headlights. Since it is summer now, condensation has not occurred until it starts raining.

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.

Engine will crank but not start. There is no communication with the integrated fuel module (TFE) whendiagnosing with ISTA. The following two fault codes will be stored in the DME: 032B43 - Low fuel pressure system, electric fuel pump: pressure value too low CDA594 - Message (- 0x33E) missing, receiver DME, transmitter TFE

Customers may state that the alarm system (DWA) is not active after locking their unoccupied vehicle. Depending on the vehicle’s equipment and settings, no acoustic or optical confirmation (folding the mirrors/blinking confirmation) is noticeable. Additionally, the red anti-theft alarm LED in the interior mirror does not briefly flash every 2 seconds, indicating the alarm is armed.

The Dynamic Stability Control (DSC) warning light comes on while driving. The following DSC fault codes for the wheel speed sensors are stored: 480712 and/or 480715 and/or 480718 and/or 48071B They cannot be cleared, even though the wheel speed sensors work correctly and no problem can be found with the wiring harness.
