NHTSA Complaint #10681900 — 2011 CHEVROLET SILVERADO 3500

EXHAUST FLUID QUALITY POOR APPEARED ON THE DASH DISPLAY, SO I TOPED IT OFF WITH MORE FRESH DEF AND THE WARNING WENT AWAY.3 DAYS LATER THE SAME WARNING CAME BACK ON THE DASH DISPLAY ONLY WITH A NEW WARNING WITH IT THAT SAID VEHICLE SPEED WILL BE LIMITED TO 55MPH NEXT FUEL FILL, IT DID! I TOOK THE TRUCK TO THE DEALER THEY FOUND BAD NOX SENSORS 1&2.REPAIRS WHERE NOT DONE BECAUSE I FELT THAT SHOULD BE SOME SORT OF RECALL ON DEFECTIVE PARTS THAT CONTROLS THE DRIVABILITY OF A VEHICLE. ON FEB-4-2015 I RECEIVED A LETTER FROM GM AFTER 2 YEARS TELLING ME THAT MY TRUCK MAY HAVE NOX SENSORS THAT CAN BECOME CONTAMINATED AND THAT GM IS EXTENDING THE WARRANTY ON THE NOX SENSORS AND THE WIRE CONNECTORS FOR 10/YRS. 120.000 MILES WHICH EVER COMES FIRST. SO I GO BACK TO THE DEALER AND SHOW THEM THE LETTER FROM GM AND SHOW THEM MY RECEIPT FROM WHEN I CAME IN 2 YEARS AGO THAT SHOWS THAT THE NOX SENSORS WERE DEFECTIVE WAY BACK IN 2013 AND ARE STILL ON THE VEHICLE AND I NEED THE REPAIRS DONE PER THE LETTER FROM GM. THE DEALER IS REFUSING TO REPAIR THE VEHICLE BECAUSE OF THE MILEAGE THAT IS NOW ON THE VEHICLE, HOWEVER THE DEFECTIVE PARTS THAT FAILED WHEN THE VEHICLE WAS WITHIN THE MILEAGE ARE STILL ON THE VEHICLE AND I FEEL SHOULD BE REPLACED AND REPAIRED OR REIMBURSEMENT FOR $800.00 PROGRAMMER. I HAVE CONTACTED CHEVROLET AND THEY ARE WORKING WITH THAT DEALERSHIP TO TRY AND RESOLVE THIS ISSUE. CASE NUMBER IS AVAILABLE IF NEEDED, GM LETTER NUMBER IS 13386. *JS
