2015 BMW 528I

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.

the vehicle was driven for approximately 30 minutes, operating with zero dashboard warnings or performance indicators. The vehicle was then parked on my property and turned off completely. Approximately two hours and thirty minutes later, the vehicle spontaneously ignited while stationary and unoccupied. The local fire department responded and successfully extinguished the blaze. Both physical observations and my home security camera footage confirm that the point of origin was the front right passenger side of the engine compartment. This exact location houses the factory electric water pump and its electrical plug connector, directly matching the failure mechanism detailed in NHTSA Campaign 24V608000, wherein fluid intrusion causes a severe, persistent electrical short circuit capable of igniting a fire hours after the vehicle is parked. The car is completely totaled because of this.

The contact owns a 2015 BMW 528i. The contact stated that while his vehicle was parked, the coolant pump connector caught on fire, which was connected to a after market Coolant pump. The failure experienced was a localized electrical fire that originated at the coolant pump connector and aftermarket coolant pump while the vehicle was parked. The contact referenced NHTSA Campaign Number: 24V608000 (ENGINE AND ENGINE COOLING, ELECTRICAL SYSTEM) but was told by the dealer they could not repair the recall due to the vehicle having an aftermarket coolant pump. The contact stated he originally replaced the coolant pump with an aftermarket one due to a failure, as advised in the recall notice. The vehicle was occupied during the failure. There was grey smoke coming from the engine and inside the vehicle, with flames that were coming from the hood and under the engine. The fire originated specifically within the coolant pump assembly and its associated electrical connector, with the thermal damage concentrated in that area before spreading. The fire department was able to extinguish the fire. The vehicle was towed to the dealer. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 120,000.

On the morning of November 2, 2025, around 10:30, I had drove up to the church, parked my car. What I thought was an overheated engine. I decided to go inside the church and deal with what I thought was an overheated engine. About 12-25 minutes later, while inside the church, I got new that a Black BMW was on fire. Someone had already called the fire department and police. The engine is totally destroyed, and beyond repair. It is more likely than not the faulty water pump is the causation of the fire. I had no previous maintenance issues with the car. I had not received any notification of a recall, nor was I aware prior to November 2, 2025.
