WE RECEIVED A RECALL NOTIFICATION IN FALL 2016 REGARDING KEYMINDER MALFUNCTION. TOOK VEHICLE TO DEALER TO FIX AND THEY REPROGRAMMED THE MYLINK SYSTEM PER THEIR SERVICE BULLETIN INSTRUCTIONS. THIS DID NOT FIX THE PROBLEM. WHEN THE KEY IS LEFT IN THE IGNITION THE CAR FAILS TO SIGNAL WHEN THE DRIVER DOOR IS OPENED MAKING IT EASY TO LOCK THE KEY IN THE IGNITION. THIS HAPPENED ONCE AFTER THE SUPPOSED REPAIR AND LOCKOUT ASSISTANCE WAS REQUIRED. HAVE TAKEN THE CAR BACK TWICE SINCE THE INITIAL "FIX" SINCE IT STILL ISN'T WORKING. THEY FINALLY ATTRIBUTED THE PROBLEM TO A FAULTY IGNITION SWITCH THE LAST VISIT. THEY WILL NOT FIX UNDER WARRANTY/RECALL. HOPEFULLY THIS ISN'T ANOTHER POTENTIALLY DEADLY GM IGNITION SWITCH ISSUE!

WHEN THE CAR CAME TO A COMPLETE STOP AT A STOP LIGHT THE ENGINE WAS SURGING WITHOUT APPLICATION OF THE ACCELERATOR PEDAL. THE CHECK ENGINE LIGHT CAME ILLUMINATED. WE CONTINUED DRIVING UNTIL ABOUT AN HOUR LATER WHEN THE CAR WAS PUT IN PARK IN THE DRIVEWAY THE ENGINE SURGED UNTIL I SHUT IT OFF. THE CHECK ENGINE LIGHT REMAINED ILLUMINATED AND WAS TAKEN TO THE LOCAL DEALER THE NEXT DAY. THE SERVICE ADVISOR REQUESTED WE BRING IT BACK THE FOLLOWING MONDAY. THE CHECK ENGINE LIGHT TURNED OFF WHILE DRIVING SATURDAY. DURING THE DRIVE BACK TO THE DEALER FOR THE MONDAY APPOINTMENT AND STOPPED AT A STOP LIGHT THE ENGINE RPM'S DROPPED IN HALF AND RAN ROUGH FOR A FEW SECONDS. THE RPM DECREASE AND ROUGH RUNNING HAS BEEN A LONGER TERM ISSUE THAT HAS BEEN PREVIOUSLY DIAGNOSED WITH NO RESOLUTION. I WAS ADVISED BASED ON CURRENT DIAGNOSIS THAT THE EVAP PURGE CONTROL SOLENOID NEEDS TO BE REPLACED.

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.

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.
