NHTSA Complaint #11012750 — 2011 CHEVROLET SILVERADO 3500

DIESEL EXHAUST FILTER (DEF) AND FLOW REDUCTION TUBE ON DURAMAX LML ENGINE. FAUTLY DEF REQUIRES EXTREMELY HIGH TEMPERATURES TO CLEAN - OR REGENERATE - CAUSING THE DEF AND REDUCTION TUBE TO FAIL. HIGH TEMPERATURES ARE A FIRE HAZARD TO VEHICLE AND GRASS OR OTHER TERRAIN OVER WHICH THE TRUCK IS PARKED. GM NO LONGER MANUFACTURES THE REDUCTION TUBE, GM PART NUMBER 25960609 FORCING THE CONSUMER TO WAIT FOR GM TO MAKE PART ON SPECIAL ORDER BASIS - OVER 30 DAYS - OR FORCE CONSUMER TO REMOVE DEF OR MAKE OTHER FABRICATION, ORDER TO OPERATE THE VEHICLE. GM IS AWARE VIA CUSTOMER SERVICE AND DEALER COMPLAINTS THAT THE LACK OF PART 25960609 AVAILABILITY IS A NATION-WIDE PROBLEM AND HAS A HIGH FAILURE RATE. GM STOPPED PRODUCTION AS A COST SAVING MEASURE. THE DURAMAX LML ENGINE IS IN SERVICE MOSTLY AS COMMERCIAL VEHICLE FLEET. THUS, THERE IS A HIGH PROBABILITY OF UNSAFE FABRICATION IN ORDER TO RESTORE VEHICLE OPERATION.
