TO AVOID A HEAD ON COLLISION I HAD TO MOVE TO THE RIGHT OF MY LANE AND I HIT A MOUNTAIN HEAD ON AND NEITHER THE DRIVER OR PASSENGERS AIRBAG DEPLOYED. THE VEHICLE OVER TURNED ON ITS LEFT DRIVER SIDE AFTER SKIDDING ALONG PAVEMENT FOR A FEW YARDS IT FINALLY CAME TO A STOP. THERE WERE NO PASSENGERS. I WAS THE DRIVER AND SUSTAINED LACERATIONS TO MY HEAD BRUISING IN CHEST AREA AND A PUNCTURED LEFT LUNG. THE VEHICLE WAS IN MOTION GOING 35 MPH

WE WERE DRIVING ON THE INTERSTATE IN HOUSTON AT APPROXIMATELY 60-65 MPH APPROACHING A HILL. WHEN REACHING THE TOP OF THE HILL, THERE WAS A PARKED CAR IN THE MIDDLE OF THE HIGHWAY AND WE SLAMMED INTO THE BACK END OF IT. BOTH VEHICLES WERE TOTALED. FORTUNATELY, WE WERE WEARING SEAT BELTS AND WERE NOT TERRIBLY INJURED. JUST REAL JARRED UP.THE AIR BAGS NEVER DEPLOYED. WITH A HIT THAT HARD THEY SHOULD HAVE. *TR

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. WAS TOLD THAT THEY COULDN'T REPLICATE THE PROBLEM THAT I WAS DESCRIBING AND THAT I SHOULD REST ASSURED BECAUSE "DIESEL WON'T BURN ANYWAY". *TR
