TAKATA RECALL. THE ISSUE WITH MY CAR IS THAT THE ENGINE IS SHUTTING OFF WHILE COMING TO A STOP. WHETHER THE CLUTCH IS ENGAGED ALL THE WAY OR IF IT'S JUST IN NEUTRAL. SUDDENLY THE RPM'S JUST DROP TO ZERO AND I WOULD HAVE TO RESTART THE CAR AGAIN BY HITTING THE START ENGINE BUTTON. THIS HAD HAPPENED MULTIPLE TIMES IN THE PAST FEW COUPLE OF MONTHS. OTHER THAN THAT THE CAR STILL RUNS SMOOTH AND EVERYTHING ELSE IS FINE. I HAVE ALMOST 18000 MILES ON IT. I REALLY HOPE FORD COULD FIGURE OUT WHAT THE PROBLEMS IS.

TL* THE CONTACT OWNS A 2016 FORD MUSTANG. THE CONTACT STATED THAT THE FRONT PASSENGER SIDE TIE ROD ASSEMBLY FAILED WHILE THE DRIVER TURNED AT LOW SPEEDS, AND THE VEHICLE ABRUPTLY VIBRATED AND SHOOK. THE DRIVER WAS ABLE TO PULL THE VEHICLE OVER ONTO THE ROAD SHOULDER. THE CONTACT PLACED THE VEHICLE INTO REVERSE. WHILE REVERSING, THE FRONT PASSENGER SIDE TIRE SEPARATED. THE VEHICLE WAS TOWED TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE FRONT PASSENGER SIDE LOWER TIE ROD ASSEMBLY BOLT FAILED. THE BOLT WAS NOT SECURELY FASTENED AND THREADED THE TIE ROD ASSEMBLY, WHICH CAUSED THE TIRE TO SEPARATE. THE MANUFACTURER WAS NOTIFIED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 409.

I BOUGHT A 2016 FORD MUSTANG IN APRIL 2016 ITS A GREAT CAR. I HAD AN ACCIDENT AND THE AIR BAGS GOT DEPLOYED LUCKILY NOTHING HAPPENED TO ME. THE VEHICLE WAS REPAIRED AT RUSSELL AND SMITH COLLISION CENTER IN HOUSTON,TX FOR 51 DAYS AT A COST OF 18000$ (CAR COST 34000$). ON THE 26TH OF MARCH 2017 A GUY SKIPPED A RED SIGNAL AND CAME INTO THE MIDDLE OF AN INTERSECTION SO I HAD TO CRASH INTO HIM AT A SPEED OF 50 MPH. THIS TIME NO AIRBAGS GOT DEPLOYED . ITS ONLY BY GODS GRACE THAT I AM NOT HARMED. I TRIED COMPLAINING TO PEOPLE AT FORD BUT ALL I AM GETTING IS A RUN AROUND FROM THEIR CUSTOMER CARE REPRESENTATIVES. ALL I WANT TO KNOW WHY MY DRIVER AIRBAG DID NOT DEPLOY EVEN AT THAT SPEED.

FORD INTELLIGENCE/NOT SO INTELLIGENT THIS MORNING I WAS PUTTING MY 2 YEAR OLD CHILD IN HER CAR SEAT AS I NORMALLY DO WITH THE CAR STARTED AND I PLACED MY PURSE AND THE KEYS IN THE FRONT SEAT OF THE CAR. AFTER SECURING MY CHILD I CLOSED THE DOOR TO WALK AROUND AND GET IN AND THE DOORS WERE LOCKED. MY CAR WAS RUNNING AND MY 2 YEAR OLD BABY WAS FRANTICALLY SCREAMING IN THE BACK SEAT OF THE CAR. WHY DID THIS HAPPEN? WHEN I CONTACTED FORD, THEY SAID THE CAR WAS NOT SUPPOSED TO LOCK WITH THE KEYS INSIDE, SO WHY DID IT HAPPEN?

1EA21002 · 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.
