I EXPERIENCED A SUDDEN LOSS OF ENGINE POWER WHILE TRAVELLING AT HIGHWAY SPEED. I AM THE ORIGINAL OWNER OF A 2004 CHEVROLET SILVERADO 2500 FOUR WHEEL DRIVE WITH THE DURAMAX DIESEL AND ALLISON TRANSMISSION. ON SUNDAY, OCTOBER 4, 2015, SHORTLY AFTER A FUEL STOP, I WAS TRAVELING ON INTERSTATE 24 NEAR PADUCAH, KY. AT APPROXIMATELY 65 MPH IN THE LEFT LANE WITH THE CRUISE CONTROL SET, I EXPERIENCED A SUDDEN LOSS OF POWER ACCOMPANIED BY A LOUD ENGINE RATTLING, AND THE CHECK ENGINE LIGHT CAME ON. WITH SOME DIFFICULTY IN HEAVY TRAFFIC, I WAS ABLE TO MANEUVER TO THE RIGHT SHOULDER OF THE ROAD. I WAS ABLE TO DRIVE THE VEHICLE AT ABOUT 25 MPH ON THE SHOULDER. SINCE I WAS JUST A FEW MILES FROM THE PADUCAH EXIT, I LIMPED THERE AND INTO A HAMPTON INN PARKING LOT. AAA RESPONDED AND TOWED THE TRUCK TO ROYAL OAKS CHEVROLET IN PADUCAH. SINCE IT WAS A SUNDAY, THE SERVICE DEPARTMENT WAS CLOSED. THE NEXT MORNING, THE DEALERSHIP'S SERVICE DEPARTMENT PULLED UP CODES PO202 AND P2149. THE SERVICE MANAGER REPORTED THAT THERE WAS A SERVICE BULLETIN ON THIS ISSUE AND THAT IT WOULD BE SEVERAL DAYS BEFORE THE REPAIR PARTS WOULD BE AVAILABLE. I LATER LEARNED THAT THE SERVICE BULLETIN IS #05-06-04-047C. THE BULLETIN ADDRESSES "A SEVERE REDUCTION IN ENGINE POWER (LIMP HOME MODE)" I WAS CHARGED $1,076 FOR REPAIRS FOR A KNOWN DEFECT THAT CHEVROLET KNEW ABOUT.

EXHAUST MANIFOLD BOLTS BROKE ON BOTH SIDES OF ENGINE, 6.0 LITER ENGINE, RESULTING IN EXTREME NOISE, POOR GAS MILEAGE, SERVICE ENGINE LIGHT BLINKING AND SMELL OF EXHAUST ENTERING CAB. WHY ISN'T THIS A RECALL ITEM SINCE SO MANY PEOPLE ARE HAVING THE SAME PROBLEM WITH CHEVY AND GM TRUCKS AND SUV'S? THE COST OF REPAIR BY A GARAGE IS ASTRONOMICAL AND IT'S IMPOSSIBLE TO DO IT OURSELVES. THE TRUCK NOW HAS ROUGHLY 112,000 MILES SINCE WE HAVE TO USE IT AT TIMES. *TR

FOUR EXHAUST MANIFOLD BOLTS HAVE BROKEN OFF SINCE I'VE OWNED THIS TRUCK AND THE MANIFOLD HAS CRACKED. IT IS A DESIGN FLAW THAT OCCURS IN MANY OF THE SIMILAR V8 EQUIPPED MODELS AND HAS BEEN WELL DOCUMENTED ON THE INTERNET. THIS SHOULD BE RECALLED BY GM. THIS PROBLEM ALSO LEADS TO FAULTY EMISSION READINGS BY THE VEHICLE AND THE CHECK ENGINE LIGHT WILL GO ON AND REMAIN ON UNTIL THIS EXPENSIVE PROBLEM IS FIXED. *TR

I HAVE A 2004 SILVERADO K2500 WITH A DURAMAX DIESEL (LLY). I BOUGHT THIS TRUCK NEW IN SEPTEMBER 2004. I PULL A FIFTH WHEEL CAMPER. MY TRUCK HAS OVERHEATED MORE THAN TWO DOZEN TIMES, AND ON SOME OCCASIONS LOST POWER, WHILE PULLING THE CAMPER UP LONG GRADES. I REPORTED THIS PROBLEM TWICE TO CHEVROLET DEALERS. I HAVE THE SERVICE ORDERS THAT CLEARLY DESCRIBE MY OVERHEATING PROBLEM. BOTH OF THESE SERVICE CALLS WERE WHILE THE TRUCK WAS UNDER WARRANTY, BUT THE DEALERS COULD NOT FIX THE PROBLEM. LATER WHEN THE TRUCK WAS OUT OF WARRANTY, I FOUND OUT THAT GENERAL MOTORS RECOGNIZED THE OVERHEATING PROBLEM AND ISSUED A SERVICE BULLETIN #06-06-04-036D THAT DESCRIBES MY HEATING PROBLEM EXACTLY. THIS SERVICE BULLETIN WAS ISSUED PRIOR TO EITHER OF MY COMPLAINTS ABOUT OVERHEATING. THE COST OF IMPLEMENTING SERVICE BULLETIN #06-06-04-036D IS APPROXIMATELY $1,300 DOLLARS, SO GENERAL MOTORS RECOGNIZES THAT THIS SERIES TRUCK HAS A SIGNIFICANT OVERHEATING PROBLEM, BUT APPARENTLY THEY ARE HIDING THIS FIX FROM THE OWNERS UNTIL THE VEHICLE IS OUT OF WARRANTY. I CAN GIVE MANY INSTANCES WHERE THIS OVERHEATING PROBLEM HAS CAUSED A SAFETY PROBLEM. ONE TIME I WAS PULLING THE CAMPER EAST ON INTERSTATE 40 ABOUT A 150 MILES WEST OF ALBUQUERQUE, NM WHEN THE TRUCK OVERHEATED AND LOST POWER. THERE WAS NO GOOD PLACE TO PULL OVER AND I WAS TERRIFIED AS THE HEAVY TRAFFIC HAD TO CHANGE LANES AND PASS ME. ANOTHER TIME I WAS PULLING UP TO THE NORTH RIM OF THE GRAND CANYON ON A TWO LANE ROAD WHEN THE TRUCK OVERHEATED, LOST POWER AND I HAD A LONG LINE OF TRAFFIC BEHIND ME. IT WAS DANGEROUS AS THE TRAFFIC PASSED ME WITHOUT GOOD CLEARANCE. I COULD GO ON AND ON OF SIMILAR SITUATIONS THAT CAUSED DANGEROUS CONDITIONS. THERE IS ALSO A WEBSITE AT WWW.DIESELPLACE.COM THAT HAS AN ENTIRE SECTION DEVOTED TO THE LLY DIESEL. THERE ARE OVER A THOUSAND POSTS CONCERNING THIS OVERHEATING PROBLEM. *TR

I OWN A 2004 CHEVROLET SILVERADO 2500. IT HAS A BROKEN EXHAUST MANIFOLD BOLT. AFTER RESEARCHING THIS PROBLEM ON THE INTERNET, I FOUND THERE ARE APPROXIMATELY 12,000,000 GM VEHICLES WITH THIS PROBLEM. WHY HASN'T THE NHTSA ISSUED A RECALL ON THESE VEHICLES? IT SEEMS TO ME THAT THE EPA WOULD HAVE DONE SOMETHING ABOUT AS THE BROKEN BOLT IS ALLOWING EXHAUST INTO THE AIR WITHOUT GOING THROUGH THE CONVERTER. I DON'T KNOW AT WHAT MILEAGE THE BOLT BROKE OR AT WHAT SPEED I WAS GOING WHEN IT HAPPENED. *TR
