Parked on a slight hill, shifted out of drive and applied the ebrake by pulling up firmly. Unbucked my seat belt, opened the door, and got out of the vehicle. Left the door open to go in my house, grab my wallet, and come back. The car stayed in neutral instead of shifting into park which should have happened but multiple components of the car failed to detect me exiting (door latch sendor, software, seat sensor, seat belt sensor). Leaving the car in neutral meant the parking brake was all that was available to hold the car. As it turns out, the electronic brake was not strong enough to do so, and the car rolled down the hill hitting another car, pushing that car into a structure and causing my car to be totaled. This never happened before but due to car not shifting into park with exiting, the vehicle became a rolling hazard putting all people and property around it at risk. I did not hear or see any warning messages as I had exited the car as I had always done previously. I should not have to turn off the car (press power on/off) to engage park or there should be a "park" button like most cars. Given there is no labeled park, the system gives you no indication of what steps you have to take if autopark doesn't engage. My car has been totaled and released to copart. It may be available for inspection from them.

BMW SAYS THAT THE ONLY REPAIR IS TO REPLACE THE ENTIRE HOUSING FOR $2100. THIS WILL NEED TO BE DONE ON THE OTHER SIDE EVENTUALLY, AS THE INSULATION IS DETERIORATING IN THAT HOUSING AS WELL. I HAVE READ ONLINE THAT THIS IS A COMMON PROBLEM IN MANY DIFFERENT MODELS BECAUSE OF THE TYPE OF WIRING THAT WAS SPECIFIED BY BMW JUST DOES NOT HOLD UP UNDER HIGHER TEMPERATURES. KNOWING THAT IT WILL BE SUBJECT TO HIGHER TEMPERATURES IN THE ENGINE COMPARTMENT IS A DESIGN OVERSIGHT AND WILL LEAD TO DANGEROUS MALFUNCTIONS WHEN OPERATING THE VEHICLE. IT IS JUST A MATTER OF TIME.

These inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, high temperatures, and high temperature cycling.
Consequence & remedy
Consequence: An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.
Remedy: BMW will notify owners, and dealers will replace the driver air bag. On X5 and X6 vehicles, only the inflator will be replaced. All repairs will be performed free of charge. The recall began March 11, 2020. Owners may contact BMW customer service at 1-800-525-7417.

Consequence & remedy
Consequence: A loss of electrical power can cause the vehicle to stall, increasing the risk of a crash.
Remedy: BMW will notify owners, and dealers will replace and secure the positive battery cable connector, free of charge. The recall began August 14, 2019. Owners may contact BMW customer service at 1-800-525-7417. Note: This recall is an expansion of a previous recall, number 18V-314.

1EA21002 · Desiccated Air Bag Inflator Rupture
Opened Sep 17, 2021 · No close date supplied
Status: open (inferred from source dates) · Air Bags:frontal:driver Side:inflator Module; Air Bags:frontal:passenger Side:inflator Module
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.
