POWER TRAIN - TRANSMISSION FAILURE - I WAS TRAVELING ON THE INTERSTATE AT 70 MPH AND ALL OF A SUDDEN MY CAR LOST POWER AND WENT TO 5 MPH; THE RPM'S REVVED AT 3500 YET NO POWER WENT TO THE WHEELS. IT WAS AN EXTREMELY PRECARIOUS SITUATION IN WHICH I WAS NEARLY RAMMED BY SEVERAL VEHICLES BEFORE I LIMPED OFF THE EXIT AT 5 MPH; STILL VERY MUCH IN DANGER. I WAS ABLE TO PULL INTO A SAFE SPACE AND CALLED AAA FOR A TOW. IT WAS A SATURDAY NIGHT SO NO SERVICES WERE AVAILABLE. THIS CAR ONLY HAS 37,000+ MILES ON IT, HAS BEEN REGULARLY SERVICED BY THE DEALER AND IS OUT OF WARRANTY ON THE POWER TRAIN. NO CAR SHOULD HAVE ITS TRANSMISSION GO OUT WITH SUCH LOW MILEAGE AND REGULAR SERVICE. THIS IS A SERIOUS SITUATION AND A FLAW IN THE TRANSMISSION SYSTEM OF THIS CAR. COST TO REPAIR FOR A NEW TRANSMISSION BY THE DEALER IS SET AT $4100, VERY UNREASONABLE FOR A CAR WHO'S WARRANTY JUST WENT OUT THREE MONTHS AGO. THE DANGER OF A CAR GOING FROM 70 MPH TO 5 MPH WITH NO WARNING WAS FRIGHTFUL AND I AM GRATEFUL TO BE HERE AND THAT NO ONE CRASHED INTO ME. I HAVE ESCALATED THIS UP TO GM FOR INVESTIGATION.

TO BEGIN, I HAVE BEEN HAVING A SHIFT FLARE PROBLEM WITH MY AUTOMATIC TRANSMISSION. THERE ARE NO TROUBLE CODES IN THE SYSTEM. THIS WOULD HAPPEN WHEN I WOULD GET OFF THE HIGHWAY WHEN THERE WAS A LOT OF TRAFFIC OR WHEN THE CAR WAS RUNNING FOR A LONG TIME. THE PROBLEM WENT AWAY WHEN THE CAR WAS COOLED AND WAS PARKED FOR SEVERAL HOURS. THE RPM WOULD SPIKE ABOUT 200RMP WHEN ACCELERATING. THIS WOULD HAPPEN FROM 2ND TO 3RD GEAR. I HAVE CHANGED THE FLUID AND I HAD TO PUT A LITTLE MORE THAN HALF A QUART OF FLUID INTO IT. THE TRANSMISSION IS LEAKING FLUID. ONE THING THAT I NOTICED WAS THAT THE DRAIN PLUG BACKED OUT. I DON'T KNOW WHY THIS HAPPENED BUT IT LEAKED AROUND IT. THERE IS ANOTHER SMALL LEAK WHERE THE ENGINE AND TRANSMISSION MEET. THIS IS A VERY SMALL LEAK AND IT ONLY LEAKS IN FREEZING TEMPERATURES. THE LEAK THAT HAS BEEN HAPPENING WHERE THE ENGINE AND TRANSMISSION MEET HAS BEEN HAPPENING FOR ABOUT 2 YEARS NOW. I HAVE BROUGHT THE VEHICLE IN TO HAVE SOMEONE TAKE A LOOK AT IT AND THEY SAID THAT THERE WAS NO LEAK. AT 60-65K MILES, THE FLUID IS A SOLID GLOSSY BLACK COLOR.

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.

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.
