2007 Chevrolet Silverado 2500

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 A LETTER DATED AUGUST 27, 2008, GENERAL MOTORS CORP. (GM) NOTIFIED NHTSA THAT IT WILL CONDUCT A SAFETY RECALL (NHTSA RECALL NUMBER 08V-441) TO ADDRESS A SAFETY RELATEDDEFECT THAT CAN RESULT IN ENGINE COMPARTMENT FIRE IN APPROXIMATELY 850,000 VEHICLES EQUIPPED WITH A HEATED WINDSHIELD WASHER FLUID OPTION.THE SUBJECT VEHICLES OF THIS INVESTIGATION COMPRISE OVER THREE-QUARTERS OF THE RECALL POPULATION. ACCORDING TO GM, A SHORT CIRCUIT ON THE PRINTED CIRCUIT BOARD FOR THE WINDSHIELD WASHER FLUID HEATER MODULE MAY OVERHEAT THE CONTROL-CIRCUIT GROUND WIRE. THIS MAY CAUSE OTHER ELECTRICAL FEATURES TO MALFUNCTION, CREATE AN ODOR OR CAUSE SMOKE AND IN RARE CASES IT MAY CAUSE A FIRE.AS A REMEDY, GM DEALERS WILL INSTALL A WIRE HARNESS WITH AN IN-LINE FUSE. IN ADDITION TO THE SUBJECT VEHICLES, SEVERAL OTHER GM MODELS WITH THE HEATED WINDSHIELD WASHER FLUID OPTION ARE INCLUDED IN RECALL 08V-441: MY 2006-2008 BUICK LUCERNE (MANUFACTURED AUGUST 2005 THROUGH NOVEMBER 2007); MY 2008 BUICK ENCLAVE (MANUFACTURED FEBRUARY 2007 THROUGH APRIL 2007); MY 2006-2008 CADILLAC DTS (MANUFACTURED MAY 2007 THROUGH NOVEMBER 2007); MY 2007-2008 SATURN OUTLOOK (MANUFACTURED AUGUST 2006 THROUGH APRIL 2007); AND MY 2007-2008 GMC ACADIA (MANUFACTURED AUGUST 2006 THROUGH APRIL 2007) VEHICLES.GM IS INSTRUCTING OWNERS TO TAKE THEIR VEHICLE TO A DEALER FOR SERVICE IF THEY EXPERIENCE SYMPTOMS OF WINDSHIELD WASHER HEATER MODULE SHORT CIRCUITS. GM'S RECALL RESOLVES THE SAFETY DEFECT CONCERNS PURSUED BY THIS INVESTIGATION.THIS ENGINEERING ANALYSIS IS CLOSED.

IN RESPONSE TO AN INFORMATION REQUEST LETTER SENT BY THE OFFICE OF DEFECTS INVESTIGATION(ODI) DURING PRELIMINARY EVALUATION PE08-010, GM PROVIDED ODI WITH 41 ALLEGATIONS OF NON-CRASH ENGINE COMPARTMENT FIRES INCLUDING 16 ALLEGATIONS OF FIRES ORIGINATING WITH THE IGNITION IN THE OFF POSITION.ONE OF THE FIRES WAS DETERMINED TO BE CAUSED BY AN ARSON EVENT.ODI HAS ALSO RECEIVED 5 REPORTS, 4 OF WHICH ARE OF DUPLICATIVE OF REPORTS PROVIDED BY GM, ALLEGING NON-CRASH ENGINE COMPARTMENT FIRES IN THE SUBJECT VEHICLES.IN TOTAL, ODI IS AWARE OF 41 NON-CRASHENGINE COMPARTMENT FIRES IN THE SUBJECT VEHICLES THAT ARE UNRELATED TO ARSON.EIGHT OF THE 41 FIRE ALLEGATIONS ALSO ALLEGE PROPERTY DAMAGE AS A RESULT OF THE FIRES.THIS PRELIMINARY EVALUATION HAS BEEN UPGRADED TO AN ENGINEERING ANALYSIS (EA08-010) TO FURTHER ASSESS THE SCOPE, FREQUENCY, ORIGIN AND CAUSE OF THE ALLEGED NON-CRASH RELATED ENGINE COMPARTMENT FIRES IN THE SUBJECT VEHICLES.

Odometer Fraud. The contact purchased a 2007 Chevrolet Silverado 2500. The contact stated that while attempting to sell the vehicle to a dealer, the contact was informed that there was a mileage discrepancy. The vehicle was a dealer sale. At the time of purchase, the mileage was 298,649. However, a Carfax history report confirmed an inconsistent report. The mileage was recorded at 259,054 on December 13, 2021, and later the mileage was 232,705 on April 26, 2022. The selling dealer was notified of the mileage discrepancy but denied financial compensation or a resolution.

The contact owns a 2007 Chevrolet Silverado 2500. The contact stated while driving approximately 5 MPH and turning into the driveway, the power steering and braking system malfunctioned. The contact stated that the steering wheel became difficult to turn in either direction and the brake pedal had extended to the floorboard while depressed and the vehicle would not immediately stop. Upon inspection, the contact discovered that the engine drive belt had fractured causing the failures. The vehicle was not yet repaired. The local dealer and manufacturer were not notified of the failure. The failure mileage was 200,000.
