I RECEIVED A NOTICE FROM LEXUS A COUPLE OF MONTHS AGO THAT MY IS250 WOULD BE RECALLED DUE TO'POTENTIAL FLOOR MAT INTERFERENCE WITH ACCELERATOR PEDAL'. I CALLED THE DEALERSHIP ABOUT TWO WEEKS AGO. I WAS TOLD THAT THE RECALL FOR THIS PROBLEM HAD NOT STARTED YET. IN THE LETTER, IT STATES THAT I SHOULD CONTACT YOU IF LEXUS HAD NOT REMEDIED THIS PROBLEM IN A REASONABLE TIME. I FEEL THAT THEY HAVE NOT. I APPRECIATE YOUR ASSISTANCE IN GETTING LEXUS TO COMPLETE THE NECESSARY RECALL WORK ON MY CAR. *TR

BACK ON MAY 21, 2009, I PULLED OUT OF MY DRIVEWAY IN MY 2006 LEXUS IS250 AND THE ACCELERATOR IMMEDIATELY BECAME STUCK DOWN FORCING MY CAR TO GO ALMOST 55 MPH DOWN A WINDING HILL. AT THIS POINT THE BRAKES ALSO DID NOT WORK AND I SIMPLY HAD TO WAIT FOR EVERYTHING TO BEGIN WORKING AGAIN. I WAS EXTREMELY LUCKY THIS HAPPENED AT NIGHT AND NOBODY WAS IN FRONT OF ME BECAUSE THIS IS A MAIN ROAD. I CONTACTED LEXUS THE NEXT DAY WHO INFORMED IT WAS JUST MY FLOOR MAT AND TO REMOVE THE EXTRA MAT IMMEDIATELY. WHILE I DID NOT AGREE DUE TO THE WAY BOTH THE ACCELERATOR PEDAL AND BRAKES FELT COMPLETELY LOCKED IN PLACE, I DID AS THEY SAID. NOW WITH THE RECENT RECALL ON TOYOTA MODELS, I CALLED LEXUS AGAIN WHO INFORMED ME THAT IN ABOUT 3 MONTHS I WILL RECEIVE A RECALL NOTICE AND THAT IN THE MEAN TIME I CAN COME IN AND HAVE A TECH TEST DRIVE IT WITH ME FOR "PEACE OF MIND". I WOULD LIKE TO UNDERSTAND WHY THIS CAR HAS NOT BEEN INCLUDED AND PUBLICLY ANNOUNCED IN THE RECALL WHEN THEY ARE FULLY AWARE OF THE DANGERS! BEING TOLD THE "PART" NEEDED TO TO CORRECT THE PROBLEM (BOTH THE ACCELERATOR AND THE BRAKE SYSTEM) IS NOT YET BEING MANUFACTURED FOR MY MODEL IS UNACCEPTABLE AND IN THE MEANTIME I AM TRYING TO NOT DRIVE MY VEHICLE AND HAVE THIS EXPERIENCE AGAIN. *TR

HI, WITH ALL THE NEWS LATELY REGARDING THE PROBLEMS WITH "STICKING" GAS PEDALS ON CERTAIN TOYOTA MODELS, I WANTED TO EMPHASIZE THAT I DON'T BELIEVE THE PROBLEM IS LIMITED TO TOYOTAS. I HAD E-MAILED YOU PREVIOUSLY TO DESCRIBE SIMILAR PROBLEMS MY WIFE AND I HAVE HAD WITH OUR 2006 IS 250, WHERE THE CAR FELT LIKE IT WANTED TO LURCH FORWARD WITH OUR FOOT ON THE BRAKE PEDAL. ADDITIONALLY, THE TACHOMETER NEEDLE WAS FLUCTUATING WHILE THIS WAS HAPPENING. OUR CAR EVEN DIED ONCE AT A STOP LIGHT FOR NO APPARENT REASON. THERE IS A RECORD OF OUR TAKING THE CAR INTO PUTNAM LEXUS FOR INSPECTION OF THIS PROBLEM. WE NEVER DID RECEIVE A RESPONSE FROM LEXUS TO OUR FIRST E-MAIL. AND, WE DO NOT FEEL THAT A CREEPING FLOOR MAT WAS THE CAUSE OF THE PROBLEMS WE WERE EXPERIENCING. WE FEEL THAT THE PROBLEMS WE'VE DESCRIBED NEED TO BE INVESTIGATED FURTHER SINCE IT IS SAFETY RELATED. I JUST TRIED FOUR TIMES TO SEND THIS DESCRIPTION TO LEXUS THROUGH THEIR ONLINE E-MAIL SYSTEM BUT KEPT GETTING, "OPERATION FAILED, ILLEGAL PARAMETERS." *TR

LUCKILY, SINCE NO ONE WAS ON THE HIGHWAY I WAS ABLE TO PULL INTO THE SHOULDER ALTHOUGH MY CAR WAS STILL ACCELERATING AND PUT IT IN PARK EVEN WHEN I WAS IN PARK THE ENGINE CONTINUED TO REV UP. I TURNED THE CAR OFF AND CALLED FOR A TOW TRUCK. THE LEXUS DEALERSHIP SAID THEY DID NOT FIND ANY PROBLEMS WITH MY CAR AND THEY THOUGHT IT WAS THE MAT. I HAVE NOT HAD ANOTHER PROBLEM SINCE THEN. *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.

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.
