MY 2013 CHEVY SONIC DEVELOPED TICKING SOUND SHORTLY AFTER I BOUGHT IT AT 60000 MILES. THE TICKING GOT WORSE OVER TIME AND THEN CHECK ENGINE LIGHT CAME ON. I SCANNED THE CODES AND MULTIPLE FOUR CODES WERE FOUND. P0171, P0496, P1101, AND P2270. AFTER DOING SOME RESEARCH IT SEEMED TO BE THAT MOST CRUZE, SONIC, AND TRAX VEHICLES ALL HAD THE SAME ISSUES. I TOOK IT TO THE DEALER FOR DIAGNOSTICS AND WAS INFORMED THE VEHICLE NEEDED A NEW INTAKE MANIFOLD, PURGE VALVE, PCV HOSE, AND VALVE COVER. THEY CALLED THE DEALERSHIP TO SEE IF THERE WERE ANY RECALLS AND THE ONLY ONE WAS THE VALVE COVER BUT WOULD HAVE TO PAY FOR DIAGNOSTICS TO SEE IF THEY WOULD COVER IT OR NOT. THE BREATHER DIAPHRAGM IN THE VALVE COVER GOES BAD DUE TO A FAULT INTAKE MANIFOLD ON THESE VEHICLE MODELS. THERE IS A LITTLE ORANGE GASKET IN THE MANIFOLD THAT GOES BAD AND CAUSES THE DIAPHRAGM TO GO OUT RESULTING IN HAVING TO REPLACE THE ENTIRE SYSTEM. THE INTAKE MANIFOLD NOT ONLY CAUSES GHAT ISSUE BUT CAUSES THE CAR TO GET JUMPY AT STOPS AND STALLING OUT. HAVE ALMOST HAD A FEW PEOPLE REAR END ME DUE TO THIS. THE PURGE VALVE GOES OUT AS WELL AND WHEN AT THE FUEL PUMP THE CAR WILL HESITATE TO CRANK OR RUN AT VERY LOW IDLE SHUTTING OFF MULTIPLE TIMES BEFORE IT STARTS UP AND THEN RUNS ROUGH UNTIL A DECENT AMOUNT OF FUEL HAS RAN THROUGH THE ENGINE. THE CAR WOULD NOT GET ENOUGH FUEL WHEN AT STOPS OR ON HIGHWAYS AND WOULD ALSO JUST LOSE FUEL AND CUT THE ENGINE OFF. THOSE COMPONENTS HAVE SINCE BEEN REPLACED BY MYSELF AND NO MORE ISSUES. CHEVY WILL NOT RECALL THE PARTS THAT ARE CAUSING THE ISSUES AND THEREFORE THERE IS A SAFETY ISSUE WHEN OUT ON THE HIGHWAYS.

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.

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.
