IllustrationAS WITH MANY SUBURBANS 2007 AND OLDER, I HAVE TWO CRACKS ON MY DASHBOARD - ONE BY THE PASSENGER SIDE AIRBAG, THE OTHER ABOVE THE INSTRUMENT PANEL. I BELIEVE THIS ISSSUE IS VERY WIDE SPREAD. CAN ANYTHING BE DONE? CLEARLY ITS A MANUFACTURER DEFECT.

THE ENGINE HAS A DESIGN FLAW AND CONSUMES OIL RAPIDLY, LOSES OIL AND DETERIORATES INTERNAL PARTS OF MOTOR CAUSING TOTAL ENGINE REPLACEMENT OR REPAIR. THIS MOTOR IS CURRENTLY APART OF A CLASS ACTION LAWSUIT BUT THE LAWSUIT IS ONLY FOR THIS ENGINE IN THE 2010-2013 VEHICLES. THIS MOTOR HOWEVER HAS BEEN IN GM VEHICLE SINCE 2007 AND I ASSUME THAT THE COMPANY WITHHELD THIS INFORMATION FROM CONSUMERS AND PUBLIC JUST AS THEY DID IN 2010. I BELIEVE THAT GM SHOULD BE RESPONSIBLE FOR THE DESIGN FLAW OF MOTOR IN ALL VEHICLES THAT INCLUDED THE ENGINE. PERSONALLY I HAD TO REPLACE MY MOTOR FOR EXCESSIVE OIL CONSUMPTION AT THE COST OF $7,712.13 WHICH INCLUDED TAXES. THEN, OF COURSE, THE MOTOR YOU PUT IN INHERENTLY HAS THE SAME ISSUE AND ITS JUST A MATTER OF TIME BEFORE IT FAILS DUE TO EXCESSIVE OIL CONSUMPTION. THE LAWSUIT IS GOING TO BE FILED FOR 2010-2013 MODELS I THINK THERE SHOULD BE A RECALL AND I WOULD LIKE TO SEE PRESSURE TO INCLUDE EARLIER MODELS WITH THE EXACT SAME MOTOR.

MY VEHICLE HAS AN OIL CONSUMPTION ISSUE, LIKE MANY OF THE 07-08 MODELS. WE HAVE TAKEN IT TO 2 DEALERSHIPS, AND THEY REQUEST THAT WE REPLACE THE CAM AND LIFTERS. WE HAVE BEEN TOLD BY 2 DIFFERENT CHEVROLET DEALERSHIPS THAT THIS IS A BAD DESIGN BY CHEVY, AND THEY SEE IT ALL THE TIME WITH THIS YEAR. THEY ALSO STATED THAT THEY WOULD NOT EVEN SELL OUR VEHICLE ON THEIR LOT IF WE TRADED IT IN. I LIVE IN A SMALL TOWN, AND I KNOW 4 PEOPLE WHO HAD THIS SAME ISSUE, AND HAD TO BUY NEW VEHICLES BECAUSE CHEVY DID NOT OFFER A SOLUTION. THE REPAIRS COST APPROXIMATELY $5000. OUR ONLY OPTION IS TO TRADE IT IN OR PAY THE REPAIRS OUT OF POCKET. THIS IS A BAD DESIGN BY CHEVY, AND A SAFETY ISSUE. WE CANNOT DRIVE OUR VEHICLE AT THIS TIME. WHEN THE ISSUE BEGAN IN OCTOBER OF 2016 WE WERE DRIVING DOWN THE HIGHWAY AND IT STARTED MAKING A KNOCKING NOISE. WE TOOK THE VEHICLE TO A CHEVY DEALERSHIP IN FOLEY ALABAMA, (SOUTHERN CHEVROLET) AND WERE TOLD BY THEM IT IS A BAD DESIGN, AND THEY HAVE SEEN MANY TRUCKS WITH THE SAME ISSUE. THEY DIAGNOSED AND GAVE US THE OPTION OF REPLACING THE CAM AND LIFTERS FOR $5000. WE DID NOT DO THIS AT THE TIME, AND TOOK IT TO ANOTHER MECHANIC WHO STATED HE HAD SEEN THIS ISSUE MULTIPLE TIMES HIMSELF. HE GAVE US A TEMPORARY FIX, AND WE DROVE THE VEHICLE HOME. WE TOOK IT TO OUR LOCAL CHEVY DEALERSHIP WHO TOLD US THE EXACT SAME THING. *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. Owner notification letters were mailed on March 1, 2021. Owners may contact Chevrolet customer service at 1-800-222-1020; Cadillac customer service at 1-800-458-8006; and GMC customer service at 1-800-462-8782. GM's number for this recall is N212328760.

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.

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.
