The LED chips that control the running lamps in the rear and prone to fail based on my personal experience and reading forums; I've replaced 3 so far. However, BMW has yet to acknowledge the issue and will only sell you an entire brake lamp for $400+. You can find the chip that needs replacing on Amazon for ~$15 with a Lifetime Warranty through the Amazon retailer. During normal operation, these LED lights stay lit in the rear when you're not actively braking or signaling and when you're parking so they're important for any traffic following from behind especially if it's dark. I've seen other German auto manufacturers with similar issues where the rear LED lights no longer function due to defective chips or simply not making them easily available for repair should the chip fail.

THIS HAPPENED PRIOR TO HID INSTALLS BUT OCCURRED MORE FREQUENTLY WITH HID INSTALLMENT. DEALERSHIP DISCOVERED THE ACCELERATOR PEDAL MODULE WAS FAULTY. VERY UNSAFE. APPARENTLY THE EXTRA VOLTAGE FROM THE LIGHTS WAS THE REASON FOR THE INCREASED DURATION FOR THIS FAULTY ISSUE. MULTIPLE REPORTS OF THIS ON FORUMS. CAR IS ONLY AT 46K.

1) AT 14K MILES, THE TRANSMISSION TRANSFER CASE FAILED. LOCAL BMW SERVICE SHOP REPLACED THE CASE TO RESOLVE THE ISSUE. I WAS SURPRISED BY THIS ISSUE AT THIS LOW MILEAGE AS I HAVE BEEN DRIVING MANY CARS FOR PAST 25+ YEARS, BUT NEVER HAD SUCH PROBLEMS. 2) IN LAST WEEK OF JAN , MY CAR ENGINE COMPLETELY STOPPED AND CAR CAME OFF DRIVE MODE WHILE I WAS DRIVING MY CAR ON HIGHWAY. FORTUNATELY, THERE WAS NONE BEHIND MY CAR AND I WAS ABLE TO SAFELY STOP MY CAR WITH THE EMERGENCY LIGHTS ON. CAR WOULD NOT GO IN DRIVE MODE UNTIL I HAD STOPPED ENGINE COMPLETELY. I STARTED DRIVING AGAIN, AND FEW MINUTES LATER SAME THING HAPPENED AGAIN. FORTUNATELY AGAIN THERE WAS NO VEHICLES WERE BEHIND ME *BUT I WAS SCARED TO DEATH BOTH THE TIMES WITH HEART BEATING REALLY HARD.* 3) I THOUGHT I MAY INADVERTENTLY HAVE TOUCHED SOME BUTTONS, AND THIS MAY HAVE HAPPENED, SO I DECIDED TO BE MORE MINDFUL ABOUT NOT TOUCHING ANY BUTTONS ETC AND OBSERVE ONE MORE TIME. 4) 2 DAYS I DROVE THE CAR W/O ISSUE. 5) FEW DAYS LATER, WHEN I WAS DRIVING BACK HOME, SAME THING HAPPENED AGAIN AND LUCKILY THIS TIME TOO, I DID NOT HAVE ANY VEHICLE BEHIND ME. GIVEN, IT WAS LATE IN THE EVENING (SERVICE SHOP WAS CLOSED), I DECIDED TO TAKE THE VEHICLE TO DEALERSHIP NEXT DAY. 6) NEXT DAY I TOOK THE CAR TO DEALERSHIP AND THEY RAN DIAGNOSTIC AND FOUND NOTHING. BUT THEY DECIDED TO TALK TO BMW USA FOR FURTHER DIAGNOSIS. 7) TODAY, I RECEIVED A CALL FROM THE DEALERSHIP AND THEY SAID, BMW-USA DID NOT FOUND THE ANY CAUSE THAT MAY HAVE CAUSED THE ISSUE BUT GIVEN ENGINE INTERMITTENTLY STOPPED, THEY ARE GOING TO REPLACE THE WHOLE ENGINE. EVEN AFTER REPLACING THE ENGINE, I FEEL THAT THEY DID NOT ADDRESS THE ROOT CAUSE I SUSPECT THERE IS SOMETHING MORE TO IT AND THIS VEHICLE IS NOT SAFE TO DRIVE. REPORTING THIS SEE IF OTHERS HAVE EXPERIENCED THIS AND QUALIFY FOR RECALL.

2EA21002 · 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.

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.
PE13030 · Loss Of Power Assist Braking
Opened Sep 6, 2013 · Closed Oct 25, 2013
Status: closed (inferred from source dates) · Service Brakes, Hydraulic:power Assist:vacuum
In a letter dated September 26, 2013, BMW Group submitted a safety recall notice to NHTSA identifying a defect condition in the vacuum pump oil supply that may result in loss of power assist braking in 76,191 model year (MY) 2012 through 2014 BMW 3-Series, 5-Series, X1 SAV, X3 SAV, and Z4 vehicles equipped with 4-cylinder engines (NHTSA Recall 13V-454).According to BMW, movement of the seal disk within the camshaft may result in blocking of the oil supply to the vacuum pump, resulting in improper pump operation and loss of power assist braking.On July 11, 2013, BMW initiated a change to the camshaft geometry that prevented the seal disk from blocking the oil port.BMW has not received any braking complaints related to loss of power assist after the design change was implemented in production.The owners of all affected vehicles will be contacted by mail and asked to take their vehicle to a BMW dealer who will install a locking ring into the camshaft to keep the seal disk in its proper location.BMW expects to begin dealer and owner notification in November 2013 and complete dealer and owner notification in December when the remedy is expected to be available.Based on the actions taken by BMW, this investigation is closed.
