Defect investigations
Desiccated Air Bag Inflator Rupture
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 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 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.

What 2014 BMW 435I owners say
Most recent owner complaints, unedited.
The contact owns a 2014 BMW 435I. The contact stated that while driving uphill at an undisclosed speed, the vehicle stalled without warning. The vehicle failed to restart and was towed to the dealer. The dealer determined that the fuel pump needed to be replaced and the computer needed to be reprogrammed. The dealer informed the contact that the vehicle had previously been repaired under the federal safety agency Campaign Number: 15V189000 (Fuel System, Gasoline). The vehicle was not repaired. The manufacturer was made aware of the failure and advised the contact to report the failure to the federal safety agency Hotline. The failure mileage was approximately 96,911.
Sos drive malfunction. Tsb released, see the federal safety agency complaint/ manufacturer communication dated 01jan202, the federal safety agency id number: 10171504 manufacturer communication number: b840416 dealer refuses to replace due to out of warranty and will not accept 3rd party warranty. Bmw USA, will not assist even though the problem is a known issue and defect.
Accelerated car after stop sign. Heard a loud pop and loss of power. Looked under hood and found the charge pipe plastic busted and off the throttle body.
While driving at moderate acceleration I heard a pop and felt a large decrease in power. Looked under hood and saw an obvious pipe broken off. Took it to beverly hills bmw.advised it was the 'left charge pipe' and to find out its the very few things not covered in ca emissions 7 year/70k warranty. Seams fairly common. Estimate $1,313.14!
My vehicle has 64,000 miles and I was exiting the driveway and accelerating up to 45mph when all the sudden I encountered a complete loss of power with sounded like a bang in the engine. My car immediately slowed down to under 30mph and started shaking. Luckily I was only 2 minutes from my house. I believe this part should be recalled because looking at all the complaints with other owners they have the same problem this is a plastic piece that under where in tear and pressure which is designed for it is failing. Some of the stories I've heard are pretty scary also like people being on the highway in this happening.
My 2014 bmw 435xi stalls on while driving without warning. The same issue was reported on the federal safety agency campaign number: 15v189000 for my vehicle model and year. When I input my VIN for the recall, the fuel pump issue isn't shown. For this reason, bwm will not pay to replace the fuel pump. My girlfriend had the same issue on her 2013 bmw 328i and bmw replaced her fuel pump and the problem was resolved. I believe the clean point established by bmw for this fuel pump issue wasn't correct or bad parts were still in vehicles outside of the clean point. My car has stalled on the highway while driving at least four times. It's not safe because the traffic around me has to avoid my car until I reach the side of the road to stop. I usually just turn the car off and wait a couple of minutes, restart and the car drives normal. I think it has something to due with the fuel level. The car only stalls when the fuel level is at or below 1/4 tank. Currently, I keep my car above half a tank to avoid the stalling issue. My fear is the issue will happen regardless of the fuel level. I'm sending this letter because last week I was running late and didn't get a chance to fill up the tank and my car stalled at 1/4 tank on the highway and I was almost in a accident. Please help!!!
Tl* the contact owns a 2014 bmw 435i. The contact stated that there was a strong odor of fuel. The contact also stated that while driving about 65 MPH, the drive chain malfunction light illuminated and the vehicle shook and shut off. The failure recurred several times. The vehicle was towed to the orange coast infiniti dealer located at 15550 beach blvd, westminster, ca 92683) where it was diagnosed that the fuel tank needed to be replaced. The manufacturer was not made aware of the failure. The vehicle was not repaired. The failure mileage was approximately 72,000.
Takata recall I had a headon accident, airbags didn't inflate. Car stopped with me with no warning, fuel pomp was defective. I had to replace it. All brakes system went bad with no warning. Had to replace everything left front wheel and run on flat tire blew up with no warning while. Had to be replaced. Sensors go off during winter months warning low-tires when tires are fine. Sensors go off to wear seatbelt when none is the passenger side or objects. Tail light wiring harness burned off resulted in no left tail light. I called bmw, they told me to take the car but they can't promise that they will help. Transmission has been slipping while driving. Bluetooth hardly work, it keeps disconnecting or not connecting.
My car had a strong odor of gas after sitting in my garage on days where the gas tank is full. I took it to the dealer and was told the gas tank has a leak. The issue from the dealer is: "fuel pressure sending unit which is not available separately from the fuel tank unfortunately." this is a car that was not yet 5 years old and has 33,400 miles. The car has not been in any accidents. It does not seem correct that a non-replaceable part fails on such a lightly used car. It also seems like a safety and emissions issue the manufacturer should fix. I have reported it the bmw north america but they do not accept it to be a design or manufacturing flaw and seem to feel the safety issue is my issue to deal with. I am reporting this in case it is a common problem on 2014 bmw 435i convertible gas tanks.
