THE FIRST THING THAT HAPPENED IS OUR RIGHT FRONT DOOR LOCK ACTUATOR WENT OUT AND WE JUST THOUGHT IT WAS BROKEN AND HAVE NOT HAD IT FIXED AND THEN THE SERVICE AIR BAG WARNING LIGHT HAS BEEN COMING ON FOR SEVERAL THOUSAND MILES. THEN THE TRUCK WOULD NOT START AND WE REPLACED THE BATTERY BUT EVEN AFTER DOING THAT THERE ARE TIMES WHEN THE TRUCK ELECTRICAL SYSTEM JUST GOES DEAD AND WE CAN OPEN THE HOOD SHAKE THE WIRES OR JUST WAIT AND IT STARTS WORKING AGAIN. THEN IN THE LAST FEW THOUSAND MILES THE " WARNING LIGHT" COMES ON AND A BELL STARTS RINGING AND THEN THE DRIVE TRAIN DOES NOT OPERATE CORRECTLY. I WAS ON A PROJECT AND MY WIFE TOLD ME ALL THIS AND SHE PARKED THE TRUCK AND STARTED DRIVING MY TRUCK. WHEN I GOT HOME I TOOK IT TO ALLEN SAMUELS CHEVROLET AND THEY WORKED ON IT AND SAID THAT THE COMPUTER SHOWED THE AIR BAGS AND STABILITRAC SHOWED SOMETHING HAD HAPPENED AND THEY RESET IT OR SOMETHING. I DIDN'T GET DOWN THE ROAD 10 MILES AND THE "SERVICE AIR BAG WARNING LIGHT" CAME BACK ON. THEY THEN WANTED 112.50 AN HOUR TO TRY AND FIND OUT WHAT WAS WRONG. I TOOK IT HOME AND A FEW DAYS LATER I WAS DRIVING IT AND CAME TO A STOP AND THE DOOR LOCKS STARTED GOING UP AND DOWN QUICKLY, THE STABILITRAC LIGHT CAME ON, AND THE TRUCK WOULD NOT GO OVER ABOUT 2 - 3 MPH PER HOUR. I PULLED OVER TO THE SIDE OF THE ROAD AND AFTER A MILE OR TWO EVERYTHING STARTED WORKING AGAIN. WHEN WE GOT HOME I PARKED THE TAHOE AND TURNED IT OFF AND THE WHOLE ELECTRICAL SYSTEM WENT DEAD. WE COULDN'T LOCK THE DOORS. THIS HAS HAPPENED SEVERAL TIMES. I HAVE CALLED CHEVROLET AND THEY HAVE SAID THEY WOULD PAY FOR 1/2 OF THE PROBLEM BUT YOU CALL THE DEALER AND THEY WILL NOT GIVE YOU A PRICE, THEY JUST SAY IT MAY BE THIS AND IT MAY BE THAT. IT COULD COST THOUSANDS OF DOLLARS. ALL OF THESE ELECTRICAL PROBLEMS ARE SAFETY ISSUES AND COULD COST ONE OR BOTH OF OUR LIVES OR SOMEONE ELSE. ????? *TR

Additionally, GM is recalling certain 2007-2008 Cadillac Escalade, Escalade ESV, Escalade EXT, Chevrolet Avalanche, Silverado 1500, Suburban, Tahoe, GMC Sierra 1500, Yukon, Yukon XL vehicles originally sold, or ever registered, in the states of Arizona, Arkansas, Delaware, District of Columbia, Illinois, Indiana, Kansas, Kentucky, Maryland, Missouri, Nebraska, Nevada, New Jersey, New Mexico, North Carolina, Ohio, Oklahoma, Pennsylvania, Tennessee, Virginia, and West Virginia or "Zone B." These vehicles are equipped with non-desiccated passenger frontal inflators containing phase-stabilized ammonium nitrate (PSAN) propellant. These inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, high temperatures, and high temperature cycling.
Consequence & remedy
Consequence: An inflator explosion may result in sharp metal fragments striking the driver or other occupants, resulting in serious injury or death.
Remedy: GM will notify owners, and dealers will replace the front passenger air bag inflator with an alternate one, free of charge. Interim letters notifying owners of the safety risk were mailed on February 22, 2021. Second notification letters will be mailed once the remedy is available.

GM IS RECALLING CERTAIN MODEL YEAR 2006-2009 BUICK, LUCERNE; CADILLAC DTS; HUMMER H2; MODEL YEAR 2008-2009 BUICK ENCLAVE; CADILLAC CTS; MODEL YEAR 2007-2009 CADILLAC ESCALADE, ESCALADE ESV, ESCALADE EXT; CHEVROLET AVALANCHE, SILVERADO, SUBURBAN, TAHOE; GMC ACADIA, SIERRA, YUKON, YUKON XL; SATURN OUTLOOK; AND MODEL YEAR 2009 CHEVROLET TRAVERSE VEHICLES EQUIPPED WITH A HEATED WASHER FLUID SYSTEM (HWFS). A RECALL WAS IMPLEMENTED IN 2008 TO ADD A FUSE TO THE CONTROL CIRCUIT HARNESS TO ADDRESS THE POTENTIAL CONSEQUENCES OF A PRINTED CIRCUIT BOARD (PCB) ELECTRICAL SHORT. HOWEVER, THERE HAVE BEEN NEW REPORTS OF THERMAL INCIDENTS ON HWFS MODULES AFTER THIS IMPROVEMENT WAS INSTALLED. THESE INCIDENTS RESULTED FROM A NEW FAILURE MODE ATTRIBUTED TO THE DEVICE'S THERMAL PROTECTION FEATURE. THE SIGNIFICANCE VARIES FROM MINOR DISTORTION TO CONSIDERABLE MELTING OF THE PLASTIC AROUND THE HWFS FLUID CHAMBER.
Consequence & remedy
Consequence: IT IS POSSIBLE FOR THE HEATED WASHER MODULE TO IGNITE AND A FIRE MAY OCCUR.
Remedy: DEALERS WILL PERMANENTLY DISABLE AND REMOVE THE HEATED WASHER FLUID MODULE. AN UPDATED PAGE FOR THE OWNER MANUAL WILL BE PROVIDED AND INSERTED IN THE OWNER MANUAL TO DOCUMENT THAT THE FEATURE HAS BEEN PERMANENTLY DISABLED AND REMOVED FROM THE VEHICLE. THE SAFETY RECALL BEGAN ON JUNE 11, 2010. OWNERS MAY CONTACT BUICK AT 1-866-608-8080, CADILLAC AT 1-866-982-2339, CHEVROLET AT 1-800-630-2438, SATURN AT 1-800-972-8876, GMC AT 1-866-996-9463 AND HUMMER AT 1-800-732-5493 OR AT THE OWNER CENTER AT WWW.GMOWNERCENTER.COM.

1EA21002 · 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.
