2008 SATURN ASTRA XR 2DR, 5 SPEED MANUAL, 98K MILES. P2138 CODE AND CHECK ENGINE LIGHT HAS REPEATEDLY OCCURRED, RESULTING IN FIVE REPLACEMENT ACCELERATOR PEDALS TO DATE, WITH A SIXTH PEDAL REQUIRED. ACCELERATOR PEDALS HAVE FAILED IN AS LITTLE AS LESS THAN ONE WEEK OF OPERATION, OR AS LONG AS THREE YEARS OF OPERATION. ALL PEDAL ASSEMBLIES BEING REPLACED WERE OEM DEALER PARTS. WIRING HARNESS WAS INSPECTED FOR WATER INTRUSION PER TSB 07-06-04-019E, AND DETERMINED TO BE A NON-ISSUE. AS THIS IS A MANUAL TRANSMISSION CAR, THE FIRST 1/3-1/2 OF THE ACCELERATOR PEDAL PRODUCES NO ACCELERATION, MAKING PROPER CLUTCH TO ENGINE RPM ENGAGEMENT EXTREMELY DIFFICULT AND UNSAFE. ADDTIONALLY, THE CAR MAY OR MAY NOT REMAIN IN REDUCED POWER MODE WHILE DRIVING, WHICH HAS RESULTED IN THE CAR GOING FROM PART THROTTLE TO WIDE OPEN THROTTLE CONDITIONS WITH NO ADDITIONAL DRIVER INPUT, CREATING MULTIPLE NEAR-COLLISIONS. VEHICLE BEHAVIOR DUE TO THIS ISSUE IS ERRATIC AND UNPREDICTABLE, AND THEREFORE EXTREMELY DANGEROUS. ISSUE DOES NOT APPEAR TO CORRELATE WITH WEATHER, TEMPERATURE, TERRAIN, TIME OF OPERATION, OR ANY OTHER CAUSE.

TAKATA RECALL CAMPAIGN ID NUMBER 16V063. WE GOT NOTIFIED OF THE SATURN ASTRA RECALL IN FEBRUARY OF 2016, WE GOT THE LETTER STATING THE FIX HAS ARRIVED IN APRIL OF 2017. THAT'S 14 MONTHS OF NO WORD AND DRIVING AN UN-SAFE VEHICLE, THAT THE RECALL NOTICE ITSELF SAYS, " IN THE EVEN OF AN INFILTRATOR RUPTURE, METAL FRAGMENTS COULD PASS THROUGH THE AIR BAG CUSHION MATERIAL, WHICH MAY RESULTING IN INJURY OR DEATH TO VEHICLE OCCUPANTS." IT'S FAIRLY WORRYING THAT IT TOOK 12 MONTHS TO GET A PART TO CUSTOMERS THAT COULD END UP KILLING PEOPLE. BUT IF I EVEN SCRATCH THE PAINT OF A LEASED CAR THEY WILL JUMP ALL OVER IT IN ASSESSING A PENALTY. RIDICULOUS.

THE HORN ON MY VEHICLE DOES NOT OPERATE, CREATING AN EXTREMELY DANGEROUS SITUATION FOR THE DRIVER, AS WELL AS OTHER VEHICLES AND PEDESTRIANS ON THE ROAD. THIS IS A KNOWN PROBLEM, ADDRESSED BY GM "SPECIAL COVERAGE 10276". UNFORTUNATELY, THAT SPECIAL COVERAGE DID NOT FIX THE PROBLEM, AND GM IMPLEMENTED AN EXTREMELY LOW MILEAGE LIMIT SO IT DOES NOT APPLY TO MANY AFFECTED VEHICLES. THIS PERVASIVE PROBLEM HAS BEEN KNOWN BY GM FOR YEARS BOTH IN THE USA (WITH THE SATURN ASTRA) AS WELL AS THE IDENTICAL VAUXHALL ASTRA AND OPEL ASTRA IN EUROPE.

16V063000 · Air Bags:frontal:driver Side:inflator Module

Feb 3, 2016

General Motors LLC (GM) is recalling certain model year 2006-2011 Saab 9-3 vehicles manufactured May 31, 2002, to February 15, 2011, 2006-2009 Saab 9-5 vehicles manufactured June 7, 2005, to May 28, 2009, and 2008-2009 Saturn Astra vehicles manufactured April 11, 2007, to July 24, 2008. Upon deployment of the driver's frontal air bag, excessive internal pressure may cause the inflator to rupture.

Consequence & remedy

Consequence: In the event of a crash necessitating deployment of the driver's frontal air bag, the inflator could rupture with metal fragments striking the driver or other occupants resulting in serious injury or death.

Remedy: GM will notify owners, and dealers will replace the driver's frontal air bag inflator on Saab 9-3 and 9-5 vehicles and will replace the driver's frontal airbag module on Saturn Astra vehicles, free of charge. The recall began on March 1, 2017. Owners may contact Saab customer service at 1-800-955-9007 or Saturn customer service at 1-800-553-6000. GM's number for this recall is 28810.

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.
