ENGINE REFUSED TO START IN COLD WEATHER. SAAB TECHNICIAN CONFIRMED AN ISSUE WITH INTAKE VALVES BEING DEFECTIVE. THE INTAKE VALVES WOULD NOT SEAL CAUSE COMPRESSION TO GET AS LOW AS 40 PSI CAUSING NO START CONDITION. SAAB REFUSED TO COVER IT UNDER WARRANTY ON THE 61ST MONTH OF OWNERSHIP VEHICLE CAME WITH 60 MONTH ENGINE WARRANTY AND THE COST OF REPAIR OUT OF POCKET WAS OVER $2500. THERE WERE DAYS THE CAR WOULDN'T START AWAY FROM HOME AFTER SITTING JUST ONE DAY, LEAVING ME STRANDED IN EXTREME COLD WEATHER WITH NO HEAT. GM AND SAAB KNOW ABOUT THIS ISSUE AS THEY GOT POOR QUALITY INTAKE VALVES FROM A SUPPLIER. GM HAS NOT YET CAMPAIGNED/RECALLED THESE VEHICLE, AS YOU KNOW GM CULTURE LACKS ETHICS AND HAVE COVERED UP DEATHS IN THE PAST TO SAVE MONEY. AS A GOVERNMENT AGENCY YOUR RESPONSIBILITY IS TO PROTECT CONSUMERS AND BE PROACTIVE AND NOT ACT AFTER SOMETHING HORRIBLE HAS HAPPENED. THERE ARE MORE THEN ENOUGH COMPLAINTS ON THIS WEBSITE FOR THIS ISSUE. ARE YOU WAITING FOR A DEATH TO OCCUR BEFORE ANYTHING IS DONE ? GM NEW OR OLD SHOULD BE HELD ACCOUNTABLE FOR THIS ISSUE. ITS A GM ECOTEC ENGINE, CAR WAS PRODUCED ON A GM PLATFORM. PROFITS FROM THE VEHICLE ALSO WENT TO GM. THIS ISSUE ALSO CAUSES AN INCREASE IN EMISSIONS. AS THERE IS LOSS OF COMPRESSION, CYLINDER MISFIRE OR HAS INCOMPLETE COMBUSTION CAUSING AN INCREASE IN HYDROCARBONS AND CARBON MONOXIDE IN THE TAIL PIPE. *TR

THE PASSENGER-SIDE TAILLIGHT BULBS HAVE BECOME SO DIM THAT THEY ARE VISIBLE ONLY UPON VERY CLOSE INSPECTION. THE TAILLIGHT BULBS ALSO SERVE AS THE BRAKE LIGHTS, EMITTING A BRIGHTER LIGHT WHEN THE BRAKE IS DEPRESSED. BECAUSE OF THIS MALFUNCTION, FOLLOWING CARS MAY NOT HAVE SUFFICIENT VISUAL NOTICE THAT THE CAR IN FRONT OF THEM IS BRAKING, RESULTING IN A TRAFFIC COLLISION. I UNDERSTAND THAT THIS IS A RELATIVELY COMMON PROBLEM AND WAS ABLE TO HAVE THE CONNECTOR FOR THE MALFUNCTIONING TAILLIGHT REPLACED. THIS WAS AN EXERCISE IN FUTILITY AS, ALMOST IMMEDIATELY, THE TAILLIGHT BECAME AS DIM AS IT HAD BEEN PRIOR TO THE CONNECTOR REPLACEMENT. THIS ISSUE, WHICH EVIDENTLY CANNOT BE EASILY REMEDIED, CREATES A HAZARD TO VEHICLE OCCUPANTS, AND THOSE IN CARS FOLLOWING THE AFFECTED VEHICLE. *TR

DEPRESSING BRAKES FEELS LIKE POWER BRAKING SYSTEM IS NOT ENGAGING. HAVE TO PULL OVER TO SIDE OF ROAD, AND AFTER A FEW MINUTES, BRAKES RETURN. THIS HAS HAPPENED PERIODICALLY OVER THE PERIOD SINCE I BOUGHT THE CAR NEW, DECEMBER 2009. THE CONSUMER EXPERIENCED AN INTERMITTENT BRAKE ISSUE THAT WAS EVIDENT FROM THE FIRST YEAR OF OWNERSHIP. UPON STARTING THE VEHICLE IN THE MORNING, THERE WAS BRAKE FAILURE UNTIL THE VEHICLE WARMED UP SUFFICIENTLY FOR THE PROBLEM TO BE RESOLVED. HE WOULD GENERALLY CATCH THE PROBLEM BEFORE EXITING HIS DRIVEWAY, BUT THERE WERE TIMES THE PROBLEM PERSISTED UPON SHIFTING INTO FORWARD GEAR. THE CONSUMER HAD THE VACUUM PIPE REPLACED.

2EA21002 · 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.

SAAB AUTOMOBILE AB, A SUBSIDIARY OF GENERAL MOTORS CORP. (GM), MANUFACTURED 12,317 SUBJECT VEHICLES THROUGH FEBRUARY 15, 2008, EQUIPPED WITH THE HIGH FEATURE V6 TURBOCHARGED ENGINE IDENTIFIED BY REGULAR PRODUCTION OPTION LP9.A TANDEM VACUUM BRAKE BOOSTER ASSEMBLY PROVIDES BRAKE POWER-ASSIST.THE ENGINE IS THE PRIMARY VACUUM SOURCE TO THE BOOSTER AND ITS EFFECT IS AMPLIFIED BY A VENTURI.UNDER CERTAIN CONDITIONS, SUCH AS A COLD ENGINE START OR AT HIGH ALTITUDES, AN ELECTRIC VACUUM PUMP (EVP) SUPPLEMENTS ENGINE VACUUM.A PRESSURE SWITCH MEASURES BRAKE BOOSTER VACUUM AND COMMANDS THE EVP WHEN TO TURN ON/OFF.CHECK VALVES ARE LOCATED AT THE INTAKE MANIFOLD, VENTURI, AND PRESSURE SWITCH. GM IDENTIFIED TWO ISSUES THAT AFFECT EVP PERFORMANCE: CORROSION OF ELECTRICAL COMPONENTS INSIDE THE PUMP CAUSED BY MOISTURE INGRESS THROUGH THE AIR OUTLET WHEN THE EVP SHUTS OFF AND THE VACUUM IN A SECTION OF PIPING BETWEEN THE EVP AND THE PRESSURE SWITCH IS RELEASED TO THE ATMOSPHERE; AND SILICONE CONTAMINATION OF THE ELECTRICAL CONTACTS INSIDE THE PRESSURE SWITCH RESULTING IN A NOISY OR IMPEDED ELECTRICAL SIGNAL.GM ADDRESSED EVP PERFORMANCE WITH TWO DESIGN CHANGES.IN NOVEMBER 2007, GM MODIFIED THE RUBBER PROTECTIVE CAP THAT COVERS THE EVP AIR OUTLET TO IMPROVE SEALING AND IN FEBRUARY 2008, GM ADDED A CHECK VALVE TO THE SECTION OF PIPING BETWEEN THE EVP AND THE PRESSURE SWITCH AS CLOSE AS POSSIBLE TO THE EVP IN AN EFFORT TO REDUCE THE BACK FLOW OF MOISTURE THROUGH THE PUMP. IN TOTAL, THE OFFICE OF DEFECTS INVESTIGATION (ODI) IS AWARE OF 240 SUBJECT VEHICLES AFFECTED BY THE ALLEGED DEFECT.COMPLAINANTS REPORT THAT SYMPTOMS OCCUR IMMEDIATELY AFTER A COLD ENGINE START AND ONLY FOR A SHORT DURATION (30 TO 60 SECONDS), DURING WHICH PERIOD THE AMOUNT OF BRAKE POWER-ASSIST PROVIDED TO THE OPERATOR MAY BE REDUCED DUE TO AN INOPERATIVE EVP.THE SYMPTOMS MAY BE MORE PRONOUNCED THE LONGER THE VEHICLE HAS BEEN PARKED AS THERE IS A NATURAL TENDENCY FOR THE BRAKE BOOSTER TO SLOWLY RELEASE THE VACUUM OVER TIME IF IT IS NOT REPLENISHED.FULL BRAKE POWER-ASSIST CAPABILITY RESUMES AFTER THIS BRIEF COLD START PERIOD OR IMMEDIATELY AFTER A WARM ENGINE START.THE THREE REPORTED CRASHES ALL OCCURRED AT LOW SPEEDS (< 5MPH) WHILE REVERSING FROM A GARAGE OR PARKING SPACE AND RESULTED IN MINIMAL TO MINOR PROPERTY DAMAGE. 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
