The contact owns a 2011 GMC Sierra 2500. While driving various speeds, the vehicle stalled and the check engine and exhaust gas recirculation warning indicators illuminated. The vehicle was taken to an independent mechanic where it was diagnosed that the fuel filter needed to be replaced. The vehicle was repaired; however, the failure persisted. The vehicle was taken to ranz motor co (1401 w beech St, chanute, ks 66720) where the fuel filter housing and high pressure fuel pump were replaced, but the failure recurred. The vehicle was taken to another independent mechanic where they informed the contact that the fuel injectors needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failures. The approximate failure mileage was 220,000.

Def light came on and the display saying service exhaust fuel system and refer to manual. That gave me nothing. The codes that came up is P2209 and P20B9. So the heater in the def tank is broken and the nox reading is wrong or has gone out. Then my speed was reduced to max 55 mph. Dealer said it would be $1500 to fix but after reading forums on-line there have been a lot is issues with the def system, fixing it, and then still displays issue. Am I going to get this repaired and still have an issue like others?

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?
