RECALL NO 13V-454 BRAKES/VACUUM PUMP OIL SUPPLY MY COMPLAINT CONCERNS THE FAILURE OF BMW TO COMPLETE ITS LEGAL OBLIGATION TO REPAIR MY VEHICLE (AND ABOUT 76000 OTHERS APPARENTLY) UNDER RECALL NO 13V-454. I RECEIVED A LETTER IN DECEMBER (DATED NOVEMBER 2012) INFORMING ME THAT MY VEHICLE WAS BEING RECALLED AS PART OF THIS CAMPAIGN TO FIX A POTENTIALLY SERIOUS BRAKE PROBLEM. THE LETTER INDICATED THAT WE WOULD BE TOLD WHEN TO BRING THE CAR IN FOR REPAIRS. TO DATE, I HAVE RECEIVED NO ADDITIONAL INFORMATION FROM BMW NA. I HAVE CALLED BOTH MY LOCAL DEALER AND BMW NA, BUT SO FAR HAVE RECEIVED NO ANSWER TO MY QUESTIONS. I'M FILING THIS COMPLAINT ON BEHALF OF ALL AFFECTED OWNERS WHO HAVE NOT HAD THEIR VEHICLES REPAIRED/CHECKED AND WHO HAVE APPARENTLY NOT RECEIVED ANY ADDITIONAL INFORMATION FROM BMW. BMW HAS A RESPONSIBILITY TO COMPLETE THE REPAIRS IN A TIMELY MANNER AND IF NEED BE REPLACE THE DEFECTIVE N20/N60 CAMSHAFT WITHOUT FURTHER DELAY, IF THEY CANNOT PROVIDE DEALERS WITH A LESS EXPENSIVE REPAIR SOLUTION. BRAKE DEFECTS SHOULD BE REPAIRED IN A TIMELY MANNER (I NOTE THAT BMW REPLACED CAMSHAFTS IN MANY VEHICLES SLATED FOR SALE LAST SUMMER). BMW KNEW ABOUT THIS PROBLEM LAST SUMMER, ISSUED A RECALL IN SEPTEMBER 2012 AND YET STILL HAS NOT REPAIRED THE VEHICLES IN QUESTION. I'M FORMALLY ASKING BMW TO OPEN AN INVESTIGATION OF THE MATTER AND DO WHAT IT IS NECESSARY TO MAKE SURE THAT THE VEHICLES UNDER RECALL ARE REPAIRED BEFORE THERE IS A SERIOUS ACCIDENT. BMW HAS IDENTIFIED THE PROBLEM. PLEASE REOPEN THIS CASE AND ADDRESS THIS COMPLAINT WITHOUT FURTHER DELAY. *TR

I WAS GOING 50 MPH ON THE SAWMILL PARKWAY. THERE WAS A RED LIGHT AHEAD AND I TOUCHED THE BRAKES TO STOP. THE CAR DID NOTHING SO I PUSHED HARDER ON THE PEDAL. IT TOOK A LOT OF STRENGTH TO BRING THE CAR TO A STOP. I CONTINUED 20 MINUTES TO MY GARAGE IN MANHATTAN WITH NO INCIDENT. I ARRIVED HOME TO FIND A RECALL LETTER FROM BMW INFORMING ME OF A POSSIBLE PROBLEM WITH THE POWER BRAKES: "RECALL CAMPAIGN NO. 13V-454: VACUUM PUMP OIL SUPPLY". WHEN I CALLED THE DEALER THEY HAD NO IDEA OF THIS RECALL. WHEN I GO ON BMW'S WEBSITE AND INPUT MY VIN, IT SAYS THERE ARE NO RECALLS. THE LETTER FROM BMW STATES, "IF YOU NOTICE A DECREASE OF POWER BRAKE ASSIST, DO NOT CONTINUE TO DRIVE YOUR VEHICLE". THE LETTER ALSO STATES THAT THERE ARE NO PARTS YET IN THIS COUNTRY TO REPAIR THE PROBLEM. WHEN I PHONE THE NUMBER TO CONTACT BMW REGARDING THIS MATTER, THERE IS A RECORDING THAT TALKS ABOUT A "BRAKE LIGHT" PROBLEM WITH THE X5 AND NOTHING ABOUT THE BRAKES OF THE X1. MY DEALER TOWED THE CAR AND GAVE ME ANOTHER X1 AS A LOANER. WHEN I INQUIRED IF THE LOANER WAS ALSO PART OF THE RECALL, THEY COULD NOT ANSWER MY QUESTION. THE FACT THAT BMW KNOWS THERE IS A PROBLEM BUT HAS NOT INFORMED THEIR DEALERS IS RIDICULOUS. ALSO RIDICULOUS IS THE LACK OF INFORMATION COMING FROM GERMANY REGARDING THIS RECALL. *TR

EA21002 · 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.

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.
