2017 BMW 530I

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.

Seatbelt alarm goes off on passengers seat and no one is seated in the seat. Received a notification from BMW that the warranty was extended to cover this problem with this model but the BMW dealership says my VIN number is not covered. They confirmed that it did need replacing but They quoted me a price of more than $2500 to fix it and claimed nothing could be done about it unless it’s paid out of pocket.

1.) The Steering Column 2.) The Column will get stuck and cannot be adjusted. 3.) Dealer has confirmed the problem & BMW USA has confirmed the problem 4.) No 5.) No Warnings BMW USA has offered a Fix for this issue and free fix if the car is under 50k miles however this is more of a safety issue as you cannot properaly adjust the steering wheel to the height needed to operate the car in a safe manner.

This is the second time I’ve had overheating issues, and it now seems more severe. I’ve noticed both coolant and oil leaking, and the car is unsafe to drive. Also fault codes related to emission. Here are the symptoms I’m experiencing: •Smoking: The car I started smoking, likely from oil or coolant leaking onto hot engine parts. Caused me to pull over at midnight on side of highway and get towed •Coolant and oil mixing: I’ve observed signs of contamination, which may indicate a gasket failure or internal leak. •Safety concerns: Due to the risk of overheating or fire, I am not driving the vehicle. •The engine could overheat, leading to catastrophic damage. •Leaked oil on hot parts could increase the risk of fire. •The compromised lubrication can cause engine seizure. I suspect the issue may be related to plastic components, as I’ve read they can become brittle over time and lead to leaks Also, the these BMWs involves the water pump's electrical pump connector allowing water to drip from the positive crankcase ventilation system through the seal, potentially causing a short circuit.

The NVLD limited emissionrelated warranty for defects in materials or workmanship has been extended to 15 years/150,000 miles as determined from the original in-service date.

It was determined that during start-up, there is a possibility that the vehicle cannot be put into gear. If this happens, a fault message will say “No drive position change possible.”

A situation may occur where the front passenger seat is not occupied; however, a “fasten seat belt” warning and a front passenger seat air bag deactivation message appears. If the situation is currently present, sit in the seat and move the seat to a slightly different position. The POL (Passenger Occupancy Light) light should now function correctly. In some cases, the Air bag Warning Light was illuminated, and the following Advanced Crash Safety Module (ACSM) fault is stored: 930A1C - Front passenger seat occupancy detection transmitting fault (moisture)
