2007 Saab 9-3 recalls and problems

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 n…

THE OFFICE OF DEFECTS INVESTIGATION (ODI) IS AWARE OF 7 SUBJECT VEHICLES THAT HAVE ALLEGEDLY EXPERIENCED ENGINE COMPARTMENT FIRES ORIGINATING AT THE COIL-ON-PLUG (COP) IGNITION COIL ASSEMBLY AND 28 ALLEGED NON-FIRE THERMAL EVENTS RESULTING IN DAMAGE LIMITED TO THE SUBJECT COMPONENT AND ASSOCIATED WIRING. ALL REPORTED INCIDENTS OCCURRED WHILE THE VEHICLES WERE ATTENDED AND IN ALL BUT ONE CASE THE SUBJECT VEHICLES WERE REPAIRED AND RETURNED TO SERVICE AFTER THE INCIDENT INVOLVING THE ALLEGED DEFECT. ACCORDING TO GENERAL MOTORS (GM), A CERAMIC CAPACITOR USED IN THE ELECTROMAGNETIC NOISE FILTER CIRCUIT INSIDE THE SUBJECT COMPONENT MAY HAVE BEEN DAMAGED DURING THE MANUFACTURING PROCESS. A FRACTURE INSIDE THE CAPACITOR MAY, DEPENDING ON ITS SIZE AND LOCATION, RESULT IN A RESISTIVE SHORT CIRCUIT. WHEN ENERGIZED, THE RESISTIVE SHORT CIRCUIT MAY CAUSE HEAT THAT CAN MELT THE POTTING EPOXY AROUND THE CIRCUIT BOARD AND LEAD TO SMOKE, ODOR AND IN SOME INSTANCES FIRE. OTHER SYMPTOMS MAY INCLUDE A MISFIRE CONDITION RESULTING IN ROUGH RUNNING AND/OR ILLUMINATION OF THE SERVICE ENGINE SOON TELLTALE LIGHT. ALL 7 FIRES OCCURRED RELATIVELY EARLY IN THE SERVICE LIFE OF THE VEHICLE AT 120, 171, 198, 207, 297, 365 AND 394 DAYS IN SERVICE, RESPECTIVELY. ODI ANALYSIS INDICATES THAT APPROXIMATELY 98% OF THE SUBJECT VEHICLE POPULATION IS NOW BEYOND THE EXPOSURE AGE AT WHICH FIRE INCIDENTS WERE OBSERVED. THE LAST KNOWN FIRE INCIDENT OCCURRED IN MAY 2009 ON A VEHICLE THAT HAD 394 DAYS IN SERVICE AND THE …

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 DE…
