WHILE DRIVING MY CAR ON THE ROAD MY ENGINE AUTOMATICALLY PLACED ITSELF ON NEUTRAL, THE STEERING FROZE, AND THE ENGINE TURNED OFF. AFTER TURNING THE SYSTEM OFF, I TURNED IT BACK ON AND DROVE AWAY NORMALLY. ONCE I APPROACHED THE A STOP LIGHT THE CAR DID THE SAME THING AGAIN BUT THIS TIME IT HAD A CRACKING-RATTLING NOISE COMING FROM THE ENGINE. WITHOUT ANY WARNINGS OR CHECK ENGINE LIGHT, OIL LIGHT, MY CAR SUFFERED FROM BROKEN MAIN AND ROD BEARINGS AS STATED BY THE BMW DEALER. THIS HAS CAUSED A LOT OF METALLIC DEBRIS THROUGHOUT THE ENGINE CAUSING ENGINE FAILURE.

THE PROBLEM OCCURS WHEN YOU SLOW DOWN- LIKE FOR A TURN, BUT DO NOT COME TO A COMPLETE STOP. THE DCT TRANSMISSION SEEMS TO HAVE TROUBLE FIGURING OUT WHAT GEAR TO SELECT BECAUSE WHEN YOU STEP ON THE GAS TO ACCELERATE, THERE IS A VERY SIGNIFICANT DELAY IN THE ONSET OF POWER- UP TO 2-3 SECONDS. BY THIS TIME, THE DRIVER IS USUALLY REALLY DIGGING INTO THE THROTTLE. THE TRANSMISSION FINALLY PICKS A GEAR, WHICH RESULTS IN THE CAR SUDDENLY LURCHING FORWARD, SOMETIMES INVOKING THE ANTI-SKIP CONTROL. THE DANGER IN THIS BEHAVIOR OCCURS WHEN MAKING A TURN INTO ON-COMING TRAFFIC AFTER SLOWING DOWN TO AROUND 10-15 MPH. AFTER THE TURN, THE CAR IS POSITIONED IN THE TRAFFIC LANE, BUT YOU HAVE NO POWER TO ACCELERATE INTO THE FLOW OF TRAFFIC. THE ONCOMING CARS ARE NOW CLOSING IN ON YOUR CAR AT A FAST RATE, AND YOU'RE BASICALLY STUCK. THIS SITUATION IS MOST PRONOUNCED IN THE "AUTO" MODE OF THE DCT TRANSMISSION, BUT ALSO OCCURS TO A LESSER DEGREE WHILE IN THE MANUAL MODE WHEN YOU SELECT SECOND GEAR IN PREPARATION FOR THE TURN. IT IS ALSO VERY REPEATABLE IN BOTH MODES. THESE PROBLEMS STARTED OCCURRING AFTER A PREVIOUS RECALL ON THIS TRANSMISSION WHERE THE ENGINE WOULD STALL UNDER HARD BRAKING OR NOT SHIFT UNDER HARD BRAKING. THE RECALL FIXED THAT PROBLEM, BUT INTRODUCED THIS PROBLEM, WHICH OCCURS ALMOST EVERY DAY WHEREAS THE PREVIOUS PROBLEM ONLY OCCURRED DURING A SPECIFIC SITUATION. *TR

BMW of North America, LLC (BMW) is recalling certain 2008-2013 128i and 135i Convertibles, 128i, 135i, and M Coupes, 2007-2010 X3 30si and X3 xDrive30i, 2013-2015 X1 sDrive28i, X1 xDrive28i and X1 xDrive35i, 2007-2013 328i, 328i xDrive, 335i, 335is, 335i xDrive and M3 Coupes, 2006-2011 328i, 328xi, 328i xDrive, 325i, 325xi, 330i, 330xi, 335i, 335xi, 335i xDrive and M3, 2009-2011 335D, 2006-2012 325xi, 328i, 328xi and 328i xDrive, 2010-2011 X6 ActiveHybrid, 2007-2013 328i, 335i, 335is, M3 Coupes, X5 30si, X5 xDrive30i, X5 xDrive35i, X5 48i, X5 xDrive48i, X5 xDrive50i and X5 M, 2009-2013 X5 xDrive35d and 2008-2014 X6 xDrive35i, X6 xDrive50i and X6M vehicles equipped with non-desiccated driver frontal air bag inflators containing phase stabilized ammonium nitrate (PSAN) that were used as interim remedy parts for previous Takata recalls. 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.
