1. THE EVENTS LEADING UP TO THE FAILURE. NONE 2. THE FAILURE, HOW OFTEN IT OCCURS, AND ITS CONSEQUENCES. PERIODIC UNCOMMANDED CHANGES IN THROTTLE. DEALERSHIP TEST EQUIPMENT SHOWS EVIDENCE OF DATA CORRUPTION ON CHANNEL 1 OF THE TWO CHANNEL THROTTLE POSITION SENSOR (TPS) OCCURRING EVERY COUPLE OF SECONDS. DRIVER PERCEPTION OF PROBLEM IS IN FORM OF JERKY THROTTLE RESPONSE AT LOW THROTTLE WITH ONE INSTANCE OF SUDDEN, UNCOMMANDED ACCELERATION. THE SUDDEN THROTTLE CHANGES HAVE RESULTED IN TRACTION LOSS ON SLIPPERY ROADS SEVERE ENOUGH THAT THE VEHICLE DEPARTED THE ROADWAY. 3. WHAT WAS DONE TO CORRECT THE FAILURE; I.E, PARTS REPAIRED OR REPLACED (AND IF OLD PART IS AVAILABLE) DEALERSHIP REPLACED THROTTLE BODY, WIRING HARNESS, AND ENGINE CONTROL MODULE IN AN ATTEMPT TO RESOLVE TPS DATA CORRUPTION PROBLEM AND DRIVABILITY PROBLEMS, BUT WAS NOT SUCCESSFUL IN THEIR PURSUIT. DEALERSHIP REQUESTED ASSISTANCE FROM THE MANUFACTURER'S FIELD ENGINEERING TEAM. A FIELD ENGINEER WAS DISPATCHED, EVALUATED THE VEHICLE, DECLARED THAT IT WAS "OPERATING WITHIN MANUFACTURER'S SPECIFICATIONS", AND TOLD THE DEALERSHIP TO IGNORE WHAT THEIR TEST EQUIPMENT WAS TELLING THEM. WHEN REQUESTED TO PROVIDE THE SPECIFICATIONS, WHAT TESTS WHERE PERFORMED TO DETERMINE COMPLIANCE, AND THE RESULTS OF THOSE TESTS, THE MANUFACTURER REFUSED. *TR

4EA21002 · 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.

EA08026 · Front Suspension Coil Spring Fracture
Opened Dec 22, 2008 · Closed Jun 4, 2010
Status: closed (inferred from source dates) · Suspension:front:springs:coil Springs
To date, ODI is aware of 142 non-duplicative complaints related to the alleged defect.In addition, ODI is aware of 2,626 subject vehicles with one or more warranty claims related to the alleged defect.In total, ODI is aware of 2,714 unique subject vehicles that have experienced one or more front suspension coil spring fractures.ODI is not aware of any crashes or injuries related to the alleged defect.The engineering design and testing data supplied by GM, along with the frequency of consumer complaints and warranty claims related to the alleged defect, tends to support the position that, in general, the coil springs that fractured on many subject vehicles did not achieve the expected service life.However, in regard to the subject vehicles, a front suspension coil spring fracture itself has little safety consequence, as evidenced by the minimal impact on vehicle ride and handling and by the number of drivers who were unaware of the failure condition for some time until alerted by service personnel.The ratio of tire punctures to coil spring fractures appears low and there are no reports of crashes, deaths or injuries related to the alleged defect. A safety-related defect has not been identified at this time and further use of agency resources does not appear to be warranted.Accordingly, this investigation is closed.The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist.The agency will continue to monitor this issue and will take further action if warranted by the circumstances.See the EA08-026 Engineering Analysis Closing Report for more details.

THE SUBJECT ISSUE DIFFERS FROM A PREVIOUS SAFETY RECALL (05V-236) AFFECTING CERTAIN MODEL YEAR (MY) 2003-2005 SAAB 9-3 VEHICLES EQUIPPED WITH A DEFECTIVE CHECK VALVE THAT COULD BECOME BRITTLE AND FRACTURE, RESULTING IN A LASTING AND TOTAL LOSS OF BRAKE POWER-ASSIST AT ANY TIME.THE DEFECTIVE CHECK VALVE DID NOT MEET LIFETIME DURABILITY REQUIREMENTS AND GM PREDICTED A 100% FAILURE RATE AT LESS THAN 4 YEARS OF SERVICE.IN COMPARISON, GM PREDICTS AN EVP FAILURE RATE OF APPROXIMATELY 6.4% AT 3 YEARS IN SERVICE FOR THE SUBJECT VEHICLES RESULTING IN REDUCED BRAKE POWER-ASSIST FOR A SHORT DURATION.THE SUBJECT ISSUE ALSO DIFFERS FROM A PREVIOUS ODI INFLUENCED SAFETY RECALL (03V-474) TO ADDRESS EVP MOISTURE INGRESS IN CERTAIN MY 2000 VOLVO S40 AND V40 VEHICLES.THE RECALLED VOLVO VEHICLES UTILIZED A STEEL VACUUM PIPE BETWEEN THE EVP AND THE BRAKE BOOSTER.MOISTURE INGRESS AND SUBSEQUENT CORROSION COULD COMPROMISE THE VACUUM PIPE RESULTING IN A LASTING AND TOTAL LOSS OF BRAKE POWER-ASSIST.MOISTURE DOES NOT APPEAR TO HAVE A SIGNIFICANT IMPACT ON THE POLYETHER-ESTER PLASTIC VACUUM PIPE USED IN THE SUBJECT VEHICLES. A SAFETY-RELATED DEFECT HAS NOT BEEN IDENTIFIED AT THIS TIME AND FURTHER USE OF AGENCY RESOURCES DOES NOT APPEAR TO BE WARRANTED.ACCORDINGLY, THIS INVESTIGATION IS CLOSED.THE CLOSING OF THIS INVESTIGATION
