2011 GMC SIERRA 2500 with 118500. miles
My 2011 Gmc duramax displays codes (P0676), (P2493), (P122D0 and (P140A) related to the egr and throttle body. I located special warranty work #14353. I am told by gm customer care that my particular vin is not included in the duramax diesel warranty issue. I located the following: 02/03/17nhtsa id: 10090458 tsb id: 14353 14353 - special coverage. On some vehicles, the service engine soon light may illuminate due to an inoperative exhaust gas recirculation (egr) cooler bypass valve. Dealers are to replace the egr cooler bypass valve. Where do i stand in getting general motors to honor the warranty?
