2014 Chevrolet Silverado 3500

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.

Takata recall. The contact owns a 2014 Chevrolet Silverado 3500. The contact received notification of NHTSA campaign number 21V054000 (Air Bags) however, the part to do the recall repair was not yet available. The local dealer was contacted and it was confirmed that the part was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The contact had not experienced a failure. Vin tool confirms parts not available.

VEHICLE PARKED AT MY HOME, STARED REMOTELY TO DEFROST. UPON ENTERING SMELLED SLIGHT SMOKE SMELL. NOTICED RIGHT SIDE OF REAR SLIDING WINDOW HAD SHATTERED.CHECKED ON LINE FOR POSSIBLE ISSUES, RECALL IN CANADA. ALSO FOUND PROGRAM N192265660 FROM G.M.. SERVICING DEALER CONTACTED GM, THEY WON'T DO ANYTHING ABOUT ISSUE. LUCKILY NO ONE WAS IN REAR SEAT WHERE THEY PROBABLY WOULD HAVE BEEN HIT WITH SHATTERED GLASS. APPEARS ELECTRICAL ISSUE CAUSED GLASS TO SHATTER.

THE 2014 CHEVY SILVERADO 3500HD DURAMAX DIESEL COMES EQUIPP ED WITH THE BOSCH CP4 INJECTION FUEL PUMP. THIS PUMP IS PRONE TO FAILURE AT ANYTIME MILEAGE WISE. THE PUMP WAS USED IN EUROPEAN DIESEL ENGINES WITH SUCCESS SINCE THEIR FUEL HAS A HIGHER CONTENT OF LUBRICITY. DUE TO THE ULTRA-LOW SULFUR FUEL MANDATED FOR US DIESEL ENGINES THIS PUMP HAS A HISTORY OF CATASTROPHIC RESULTS WHEN USED IN THE 2011-2016 DURAMAX 6.6L CHEVY ENGINES.METAL TO METAL WEAR CAUSES SMALL METAL FRAGMENTS TO ENTER THE FUEL SYSTEM THEREBY CAUSING ENGINE FAILURE. THIS EVENT CAN HAPPEN WITHOUT WARNING. IF THE ENGINE HAS STOPPED WHILE IN MOTION THIS PRESENTS AN ACCIDENT WAITING TO HAPPEN. MY CONCERN IS THAT I TOW A 14000LB RV 5TH WHEEL TRAILER WITH MY TRUCK. HOW CAN IT BE STOPPED SAFELY WITH OUT THE ENGINE PROVIDING POWER TO THE BRAKING SYSTEM?. THIS ENGINE IS VERY POPULAR AMONG RV'ERS, BOATERS, FLATBED HAULERS ETC; BASICALLY ANYONE MOVING A HEAVY LOAD DOWN THE HIGHWAY.IF THIS INCIDENT HAPPENS WHEN THE VEHICLE IS OUT OF WARRANTY THE REPAIRS CAN COST $8 TO 12K. MANY WEBSITES CONTAIN INFORMATION ABOUT THE CP4 FAILURE. MY SON HAD 2 SUCH VEHICLES IN A SMALL TRUCKING FLEET COSTING HIM OVER $20K TO REPAIR. I FEEL GENERAL MOTORS SHOULD ISSUE A RECALL OR PROVIDE OWNERS OF THIS VINTAGE TRUCK ADDITIONAL COVERAGE. THIS PUMP WAS ALSO USED BY FORD & DODGE IN THE MID 2012-2014 WITH THE SAME RESULTS. THE MAY 2019 ISSUE OF "TRAILER LIFE" MAGAZINE CONTAINS AN ARTICLE ABOUT THE BOSCH CP4 ON PAGES 77-81. TO DATE MY VEHICLE HAS NOT HAD THIS PROBLEM YET. MY SONS TRUCKS BLEW UP IN JULY 2017

THE FUEL TRANSFER PUMP, WHICH MOVES FUEL FROM THE REAR TANK TO THE FRONT TANK HAS MALFUNCTIONED. THIS HAS CAUSED THE FUEL GAUGE TO READ INACCURATELY, CAUSING ENGINE TO STOP RUNNING, HAS ILLUMINATED THE SERVICE ENGINE LIGHT MULTIPLE TIMES, DISPLAYING CODE P2068 AND P0463. VEHICLE CAN RUN OUT OF FUEL UNEXPECTEDLY, DUE TO GAUGE SHOWING MORE FUEL THAN IS AVAILABLE. THIS HAS CAUSED THE ENGINE TO STALL UNEXPECTEDLY. THIS PROBLEM IS EXACTLY AS DESCRIBED IN RECALL DOCUMENT 13421 FROM GM, HOWEVER, THE VIN NUMBER OF MY VEHICLE IS NOT INCLUDED IN THE RECALL. I HAD AN INDEPENDENT AUTO REPAIR SHOP VERIFY THE CAUSE OF THE SERVICE ENGINE LIGHT CODES, AND THEIR FINDINGS ARE CONSISTENT WITH MINE. THE VEHICLE HAS 98,000 MILE. I AM THE ORIGINAL OWNER. I HAVE SPOKE WITH GM CUSTOMER SERVICE DEPARTMENT, WHO IS LOOKING IN TO THIS, HOWEVER HAS NOT YET RESPONDED TO MY COMPLAINT. I AM AWAITING THEIR RESPONSE IN THE NEXT 24 HRS. THANK YOU.

STEERING GETS VERY HARD TO TURN (LIKE WHEN THE ENGINE IF OFF) WHEN VEHICLE IS IN MOTION AND HAS HAPPENED ON MULTIPLE OCCASIONS OVER THE PAST YEAR OR MORE. WHEN IT'S HAPPENED IT'S BEEN DIFFICULT TO CONTROL THE VEHICLE AND THE DEALERSHIP I TAKE IT TO DOESN'T THINK IT'S SOMETHING CHEVROLET IS GOING TO RESOLVE UNDER WARRANTY SINCE THEY HAVE NOT BEEN ABLE TO REPEAT THE PROBLEM THEMSELVES AT THEIR SHOP. I WORRY THAT IT WILL COME UP AT AN INOPPORTUNE TIME CAUSING A POSSIBLE ACCIDENT.
