THIS IS THE SECOND TIME IT HAS HAPPEND, MY EXHAUST MANIFOLD BOLT BREAKS. *TR

IN JUNE, 2011, I BEGAN NOTICING MY ANTIFREEZE LEVELS WERE DROPPING SLIGHTLY. THERE WERE NO NOTICEABLE LEAKS OF ANTIFREEZE ANYWHERE. I ATTRIBUTED IT TO EVAPORATION & ADDED COOLANT. OVER TIME THE TRUCK STARTED USING MORE & MORE ANTIFREEZE. A FRIEND OF MINE NOTICED A PUFF OF WHITE SMOKE COMING FROM THE TAILPIPE. AT THE TIME I DIDN'T REALLY THINK ANYTHING OF IT. LAST WEEK WHILE DRIVING HOME FROM WORK AFTER FINISHING UP A "B" TRICK JOB (11PM), I NOTICED A KNOCKING SOUND COMING FROM THE ENGINE. IT SMOOTHED OUT AFTER A FEW MILES OF DRIVING IT. THE NEXT DAY IT HAPPENED AGAIN ( I WORK 26 MILES FROM HOME) AGAIN IT SMOOTHED OUT & I WAS JUST GRATEFUL I GOT HOME SAFELY THAT NIGHT. BY THIS TIME I KNEW THERE WERE SOME SERIOUS ISSUES & DECIDED NOT TO DRIVE IT AGAIN. I BEGAN RESEARCHING THE ISSUE ON LINE & FOUND...

TL* THE CONTACT OWNS A 2005 CHEVROLET SILVERADO. THE CONTACT STATED THE VEHICLE WAS ABNORMALLY LOSING COOLANT EVERY THREE WEEKS. THE VEHICLE WAS TAKEN TO A LOCAL REPAIR FACILITY WHERE THE MECHANIC WAS UNABLE TO DETERMINE THE SOURCE OF THE LEAK. THE VEHICLE WAS NOT REPAIRED. NEITHER THE DEALER NOR THE MANUFACTURER WAS CONTACTED IN REGARDS TO THE FAILURE. THE CONTACT WAS CONCERNED WITH THE POSSIBILITY OF THE VEHICLE OVERHEATING AS HE LOCATED NUMEROUS COMPLAINTS ONLINE REGARDING THE FAILURE IN HIS YEAR, MAKE AND MODEL BUT NO RECALLS. THE FAILURE MILEAGE WAS 80,000.

VEHICLE QUITS RUNNING AND MAY RESTART AFTER 10 MINUTES OR MAY NOT. IT SHUTS OFF AT ANY SPEED AND AT RED LIGHTS. WHEN ON A HILL IT WILL ROLL BACK INTO WHATEVER IS BEHIND. THIS VEHICLE HAS BEEN TO THE DEALER 6 TIMES AND THEY CAN FIND NOTHING WRONG. SOMETIMES THERE IS POWER TO THE DASH AND LIGHTS, OTHER TIMES THE DASH GOES DARK AS IF THERE WAS NO POWER AT ALL. *TR

VEHICLE QUITS RUNNING ANYTIME, BRAKES AND STEERING "HARD", DEAD BATTERY LIKE SYMPTOM AND WILL NOT START OR RESTART AFTER QUITTING. *TR

DT*: THE CONTACT STATED THE VEHICLE INFREQUENTLY STALLED WHILE TRAVELING 70 MPH. THE SERVICE DEALER COULD NOT DUPLICATE THE ISSUE. THIS HAS OCCURRED SINCE APRIL 2005 AND HAS BEGUN TO OCCUR MORE FREQUENTLY.

DT*: THE CONTACT STATED THE VEHICLE STALLS AT ANY SPEED WITHOUT WARNING. THE VEHICLE WAS TAKEN TO THE DEALERSHIP SEVERAL TIMES. THE LEVEL SENSOR, FUEL INJECTION WIRING HARNESS, THE DIRECT FUEL INJECTION DRIVER, THE FUEL TANK, AND THE FUEL TANK MODULE HAVE BEEN REPLACED. THE SENDER PUMP ASSEMBLY WAS REPLACED TWICE. AFTER THE LAST REPLACEMENT THE CHECK ENGINE LIGHT ILLUMINATED AND THE DEALER COULD NOT DETERMINE THE CAUSE OF THE PROBLEM.

TRUCK HAS 14000 MILES, IT HAS CONSTANT OVER HEATING PROBLEMS WHILE TOWING MY 8K TRAVEL TRAILER. I HAVE TALKED WITH THE CHEVROLET DEALER ABOUT IT, THEY TOLD ME THAT THEY WERE AWARE OF THE PROBLEM BUT AT THIS TIME HAVE NO FIX. I CALL STUPID BECAUSE I HEARD ONLINE THAT THE 06 MODELS HAVE REVISED COOLING SYSTEMS AND A LARGER TURBO CHARGER. MY BELIEF IS THE FIX IS TO MUCH $$ AND THEY WILL ONLY TAKE CARE OF THE FEW PEOPLE THAT TOW AND HAVE ISSUES. I HAVE NOTICE A LOT OF INFORMATION ON THE NET ABOUT 04.5 AND 05 LLY DURAMAX TRUCK THAT TOW OVER 10000 HAVE THIS ISSUE BUT MY TRAVEL TRAILER FULLY LOADED ONLY WEIGHS UNDER 9K. THE MAJOR DOWN SIDE IS THE TRUCKS INABILITY TO MAINTAIN THE SPEED LIMIT DUE TO THE OVERHEATING WATER TEMPERATURE AND THE POWER LOSS FORMED A COOLING FAN THAT RUNS HYPERSPEEDS...
