I recently had my car serviced and the oil changed over the summer, so there were no warning indicators or service issues prior to this incident. I left for work and had no indications of any problems. I drove for about 10-15 minutes when a warning notification popped up stating engine oil pressure low. A few seconds later, the check engine light came on with a notification there was a "drivetrain malfunction". The car started to decrease speed significantly and I pulled over as soon as I could. I turned the car off and waited a couple minutes, then tried to turn it on. The car power/battery was still working properly, but the engine did not start. I had the car towed to the dealership that I use. I was notified that the drivetrain malfunction is due to "timing chain components failure" and the cost is approximately $16,000. I have taken care of any previous recalls and there are no open recalls that exist currently. In 2014, the same situation occurred, in the same car, where I also received a "drivetrain malfunction" and check engine light. During this time my vehicle also stopped working while I was driving it. Both of these incidents happened very quickly, and I am EXTREMELY lucky that no one was injured in either situation. This issue is extremely unsafe and clearly has not been fixed by the required recalls so far. I urge you to look into this further.

Car stalled while driving on highway due to drivetrain error code. Once stopped, oil pressure loss light came up. No warning lights prior to issue presenting itself at highway speeds. Initial technician belief is timing belt guide failure per other similar reports.

DRIVETRAIN MALFUNCTION LIGHT CAME ON STATING TO DRIVE MODERATELY. MAXIMUM DRIVETRAIN OUTPUT NOT AVAILABLE. CONSULT SERVICE CENTER. THE CODES WAS CDA904 NO MESSAGE (STATUS TRAILER 0X2E4) RECEIVER ENGINE ECU TRANSMITTER TRAILER. 130F20 EXHAUST CAMSHAFT OFFSET ANGEL TO CRANKSHAFT OUTSIDE TOLERANCE; 120408 BOOST PRESSURE CONTROL, CUT OFF PRESSURE RISE BLOCK AFTER PAYING $180.00 FOR DIAGNOSTIC I WAS TOLD TODAY THAT I NEED TO REPLACE THE TIMING CHAIN/ GUILD. REPLACE OIL PUMP CHAIN MODULE AND REPLACE THE VALVE COVER. THE TIMING CHAIN GUIDE IS BROKEN. THIS IS CRAZY MY CAR HAS 88000 MILES AND IS NOT PAID FOR. THE COST TO GET THIS REPAIRED IS APPROXMIATELY $6,000. THERE IS A CURRENT CLASS ACTION LAWSUIT. BMW KNOWS THAT THIS IS A PROBLEM BUT REFUSES TO DO A RECALL. THE PLAINTIFFS TAKE ISSUE WITH TWO SPECIFIC DEFECTS IN THE ENGINE'S CHAINS. THE FIRST DEFECT AFFECTS THE PRIMARY CHAIN, ALSO KNOWN AS THE TIMING CHAIN, WHICH COORDINATES THE ACTION OF THE CRANKSHAFT, CAMSHAFTS, AND CYLINDER VALVES. ACCORDING TO THE PLAINTIFFS, THE PLASTIC GUIDE ASSEMBLY FOR THE PRIMARY CHAIN IS MADE OF A DEFECTIVE POLYCARBONATE MATERIAL THAT BECOMES BRITTLE AND BREAKS APART, CREATING DEBRIS THAT LODGES IN THE CRANKSHAFT DRIVE SPROCKETS. THE DEBRIS CAN CAUSE THE PRIMARY CHAIN TO SKIP, LETTING THE CAMSHAFTS AND CRANKSHAFT FALL OUT OF SYNC AND POSSIBLY DAMAGING OR DESTROYING THE ENGINE. THE SECOND DEFECT AFFECTS THE SECONDARY CHAIN, WHICH CONNECTS THE OIL PUMP AND BALANCE SHAFT ASSEMBLY TO THE CRANKSHAFT. THE MATERIALS IN THIS ASSEMBLY CAN'T STAND UP TO HIGH-RESISTANCE WEAR, THE PLAINTIFFS SAY. THIS DEFECT CAUSES THE CHAIN TO ELONGATE PREMATURELY, SLIP, AND DAMAGE THE CHAIN SPROCKET. *JS

I IMMEDIATELY CALLED MY HUSBAND WHO TOLD ME TO PULL OVER AND SHUT OFF THE CAR FOR 5 MINUTES. HE MANAGED TO CALM ME DOWN. WHEN I RESTARTED THE CAR, THE CAR COULD NOT START I WAS VERY SCARED THE CAR WAS TOW TO BMW AND THEY STATE IT WAS RHE STARTER THAT WHEN BAD. I HAD RETURN THE CARE SEVERAL TIME TO BMW FOR THE SAME NOISE I WAS TOLD THE HAVE A TECH FROM THE HEAD QUARTER CAME OUT AND THE CAR IS PERFECTLY FINE .THE SAME HING HAPPEN 2 YEAR LATER AND I WAS ON THE HIGHWAY DURING THE INCIDENT. BMW SERVICE TOLD ME THE ENGINE FAIL AND I NEED A NEW ENGINE WHICH WOULD COST ME $10,000 WE WERE READING ALL THE COMPLAINTS AND PRIMARILY THEY ARE ABOUT THE DRIVE TRAIN MALFUNCTION - IT HAS A FAULTY PLASTIC PART, WHICH SINCE 2015 WAS REPLACED BY A METAL PART. I WAS DRIVING IN THE MIDDLE LANE OF A VERY BUSY HIGHWAY AND I COULD HAVE BEEN KILLED O). WHAT DOES IT TAKE FOR BMW OR NHTSA TO ISSUE A RECALL FOR THIS PROBLEM - A DEATH OR FEW? THERE IS NO WAY A 5 YEAR OLD CAR ENGINE SHOULD HAVE FAIL WITH JUST 70,000 MILES.

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.

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.
