2014 BMW X3

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.

In a letter dated September 26, 2013, BMW Group submitted a safety recall notice to NHTSA identifying a defect condition in the vacuum pump oil supply that may result in loss of power assist braking in 76,191 model year (MY) 2012 through 2014 BMW 3-Series, 5-Series, X1 SAV, X3 SAV, and Z4 vehicles equipped with 4-cylinder engines (NHTSA Recall 13V-454).According to BMW, movement of the seal disk within the camshaft may result in blocking of the oil supply to the vacuum pump, resulting in improper pump operation and loss of power assist braking.On July 11, 2013, BMW initiated a change to the camshaft geometry that prevented the seal disk from blocking the oil port.BMW has not received any braking complaints related to loss of power assist after the design change was implemented in production.The owners of all affected vehicles will be contacted by mail and asked to take their vehicle to a BMW dealer who will install a locking ring into the camshaft to keep the seal disk in its proper location.BMW expects to begin dealer and owner notification in November 2013 and complete dealer and owner notification in December when the remedy is expected to be available.Based on the actions taken by BMW, this investigation is closed.

The contact owns a 2014 BMW X3. The contact stated that while driving 30 MPH, the vehicle stalled. The message “Fuel Supply Malfunction” was displayed. Additionally, the contact referenced NHTSA Campaign Number: 24V527000 (Air Bags) and stated that the passenger’s side air bag was not replaced. The local dealer was contacted and informed the contact that the vehicle needed to be diagnosed. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 80,000.

I am filing a safety complaint regarding a catastrophic timing chain failure on my 2014 BMW X3 xDrive28i equipped with the N20 engine. While driving, the timing chain and oil pump drive chain failed without warning. This is a well-documented defect on BMW N20/N26 engines that has been the subject of extended warranties and numerous consumer complaints. This failure can cause sudden engine seizure, immediate loss of power steering and braking assist, and creates a serious risk of crash while the vehicle is in motion. BMW issued an Extended Limited Parts Warranty for this exact defect (timing chain and oil pump drive chain), acknowledging a manufacturing defect. However, BMW is refusing to cover my repair even though this is a known safety issue affecting thousands of vehicles. The vehicle had been properly maintained, and there were no warning signs before the failure. I purchased the vehicle in October 2021, and this defect occurred during normal use commuting to work. The cost of repair is extremely high due to the internal engine damage caused by the timing chain defect. This is not normal wear and tear. This is a known design/manufacturing defect that BMW has been aware of for years. Also, when I purchased this vehicle, the headlights, and taillights on the hatchback were not working. I had brought this up to the dealership they replaced the headlights, but did not address the tail lights. I am requesting that NHTSA investigate this defect further, and the tail lights as these failures create a significant safety hazard for drivers and other vehicles on the road.

While driving the vehicle on normal roads at10mph and above, a "cracking" sound from the top of the B-pillar(s) is heard.

The vehicle demonstrates a power loss and the malfunction indicator lamp (MIL) on. The following fault codes may be stored in the DDE: 24CE00 Hot film air mass meter: Ratio of measured to calculated air mass too high 27F000 Charge air hose monitoring in idle: Charge air hose fallen down 290900 Air system, air to EGR air mass flow plausibility: Measured air mass compared to calculated air mass too high 290A00 Air system, air to EGR air mass flow plausibility: measured air mass compared to calculated air mass too high and high charging pressure control deviation

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.

A noise can be heard from underneath the seat while the seat is being moved either forwards or backwards. This can occur to the driver’s and/or the passenger’s front seat.

This situation can result in two customer complaints: 1. Wind noise 2. Excess water entry
