I OWN A 2011 GMC SIERRA 3500 6.6 DURAMAX DIESEL TRUCK. WHEN THE TRUCK IS "REGEN-ING" THE "DPF", RAW FUEL LEAKS FROM AN EXHAUST COUPLING LOCATED AT THE TURBO AND DOWN-PIPE SATURATING THE HOT EXHAUST PIPE WITH FUEL. WHEN YOU COME TO A STOP WHILE IT IS IN THIS REGEN MODE WHITE SMOKE BOILS OUT FROM UNDER THE HOOD AND ENTERS THE CABIN INDUCING A COUGHING FIT AND BURNING EYES. I TOOK THE TRUCK TO A GMC DEALER IN SAN ANGELO TX AND TOLD THEM ABOUT THE PROBLEM.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2011 GMC Sierra 2500 Hd verdict →
