HARD STARTING COLD WITH ENGINE MISFIRE AND LOW COMPRESSION, VEHICLE STARTS AND RUNS NORMALLY WHEN HOT 2007-11 9-3 B207 & 2011 9-5 A20NFT ______________________________________________ THIS IS A RE-ISSUE OF A PREVIOUSLY PUBLISHED DOCUMENT WITH UPDATED INFORMATION HIGHLIGHTED INRED. MODELS: 2007-2008 SAAB 9-3 B207R (THIS PI DOES NOT APPLY TO THE B284 ENGINE) UPDATE: THIS CONDITION COULD ALSO OCCUR ON 2009-11 B207 OR 2011 9-5 A20NFT CONDITION/CONCERN: A TECHNICIAN MAY COMMENT OF HARD OR NO STARTING WHEN COLD. THEY MAY ALSO FIND ENGINE MISFIRES WITH DTC'S P0300, P0301, P0302, P0303 OR P0304. THE VEHICLE WILL START AND RUN NORMALLY WHEN HOT. RECOMMENDATIONS/INSTRUCTIONS: THIS CONDITION MAY BE CAUSED BY A WORN INTAKE VALVE AND IS TYPICALLY FOUND ON VEHICLES WITH 50,000 OR MORE MILES. DUE TO THE NATURE OF THIS ISSUE IT CAN BE MORE FREQUENT IN COLD CLIMATES AND COULD EXHIBIT THE CONDITION AT A LOWER MILEAGE; INVERSELY IN WARMER CLIMATES IT MAY OCCUR AT A HIGHER MILEAGE. TAC HAS FOUND INTAKE VALVE WEAR OF THE VALVE SEAT FACE WILL CAUSE SIGNIFICANT COMPRESSION LOSS IN COLD TEMPERATURES THAT WILL NOT BE READILY APPARENT WHEN HOT. TO PROPERLY DIAGNOSE THIS CONDITION PERFORM A COLD (AFTER AN OVERNIGHT STAY IS BEST) COMPRESSION AND LEAK DOWN TEST. AS AN EXAMPLE, AN ENGINE WITH A 150-175 PSI HOT CRANKING COMPRESSION READING MAY ONLY SHOW 75 TO 90 PSI WHEN COLD. ONCE A TECHNICIAN HAS DETERMINED HE HAS THE ABOVE DESCRIBED CONCERN HE MUST INITIATE A TECHNICAL ASSISTANCE CENTER (TAC) CASE BY EMAIL AT XXXX OR BY PHONE AT XXXXX PROMPT #3. TAC WILL PROVIDE THE FULL INFORMATION ON THE PARTS/REPAIR PROCEDURE WHEN THE CASE IS SET. PARTS REQUIRED: INLET VALVE 2007 TO 2011, BIOPOWER 55563529 (8 REQUIRED)

WE OWN A 2008 9-3 SAAB THAT HAS APPROXIMATELY 120,000 MILES ON IT. WHEN IT IS COLD OUTSIDE (50 DEGREES AND BELOW), OUR CAR STARTS VERY ROUGHLY AFTER 2-3+ MINUTES OF CONTINUOUS CRANKING. ONCE THE CAR STARTS AND HAS WARMED UP, IT RUNS QUITE SMOOTHLY. HOWEVER, IT CURRENTLY ISN'T STARTING AT ALL NOW AND IS IN THE SHOP. WE HAVE BEEN DOING RESEARCH ONLINE TO SEE IF THIS IS A COMMON PROBLEM AMONG OTHER 2008 SAAB OWNERS. SO FAR WE HAVE SEEN A LARGE AMOUNT OF OTHER OWNERS OF 2008 SAABS EXPRESSING THE SAME CONCERNS/PROBLEMS AND HAVE EXPERIENCED A $2,00-$3,000 EXPENSE TO FIX IT. OUR DIAGNOSIS IS THAT THERE ISN'T ANY COMPRESSION AND IT IS ASSUMED THAT THE LOWER INTAKE VALVES ARE FAULTY AND WILL NEED TO BE REPLACED FOR AN ESTIMATED COST OF $2,000-$3,000. I HAVE CONTACTED GM AND AM AWAITING THEIR RESPONSE AS TO WHETHER THERE ARE ENOUGH OTHER COMPLAINTS TO WARRANT A RECALL OR RECEIVE ANY FINANCIAL ASSISTANCE TO COMPLETE THE REPAIRS. IT APPEARS THAT THE ORIGINAL GM PARTS ARE FAULTY AND BECOME WORN, WHICH RESULTS IN DIFFICULTY IN COLDER TEMPERATURES. WE PREVIOUSLY OWNED A 2003 SAAB, WHICH WAS BUILT BY SAAB, AND WE NEVER EXPERIENCED ANY OF THESE SAID PROBLEMS.

AS IS THE CASE WITH MANY OTHER SAAB 9-3 BUILT AFTER 2006, MY DEALER'S SERVICE DEPARTMENT RECENTLY IDENTIFIED A PROBLEM WITH THE INTAKE VALVES IN MY VEHICLES ENGINE, WHICH HAS EXPERIENCED PREMATURE FAILURE AT 77,000 MILES. OTHER POSTINGS ON LINE LEAD ME TO BELIEVE THAT THIS IS MAJOR ISSUE AFFECTING THOUSANDS OF THESE VEHICLES BUILT BY GM IN YEARS 2007 AND LATER. THE CAUSE IS WIDELY KNOWN AND IS A MANUFACTURERS DEFECT RESULTING IN FAILURE OF THE VEHICLE TO START IN COLD WEATHER. THE FIX REQUIRED IS A REPLACEMENT OF ALL OF THE ENGINE INTAKE VALVES. THIS IS COSTLY FIX IN THE RANGE OF $3,000 PER VEHICLE. WHETHER GM KNEW IT WAS USING INFERIOR PARTS PRONE TO FAILURE OR NOT, THEY ARE STILL RESPONSIBLE AND SHOULD BE REQUIRED TO PERFORM THE REPAIRS AT THEIR COST, OR TO AT A MINIMUM PARTICIPATE IN SOME WAY IN THE COST OF THE REPAIRS.

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.

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
