ENGINE

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.

ENGINE

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.

MY TRUCK IS A 2004 CHEVY SILVERADO 2500 WITH 94000 MILES AND THE REAR DRIVER SIDE EXHAUST MANIFOLD BOLT HEAD IS BUSTED OFF. THIS IS NOT THE ONLY CHEVY/GMC 4.8,5.3 OR 6.0 ENGINE THAT HAS THIS PROBLEM. MILLIONS OF OTHERS HAVE THIS SAME PROBLEM AND FROM THIS FAILURE IT CAN LEAD TO FUTURE EMISSION PROBLEMS, CATALYTIC CONVERTER PROBLEMS, EXHAUST LEAK IN THE ENGINE COMPARTMENT LEADING TO EXHAUST FUMES BEING LEAKED INTO THE CAB OF THE VEHICLE WHICH WOULD BE CARBON MONOXIDE POISONING. THIS IS A MAJOR ISSUE THAT GM SHOULD TAKE CARE OF AS A RECALL !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

ENGINE AND ENGINE COOLING

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.

ENGINE AND ENGINE COOLING

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.

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM

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.

THIS HAPPENED IN THE YEAR 2008. EVERYTHING WAS FINE BUT WHEN I WOKE UP THE FOLLOWING DAY, THE SPEEDOMETER WAS POINTING AT 120MPH. IN OTHER WORDS, IT WAS A DIRECT REFLECTION FROM ITS INITIAL POINT, WHICH WAS WHEN IT WAS POINTING AT OR BELOW 0MPH.

THE EXHAUST MANIFOLD BOLTS ARE BROKEN ON MY 2004 CHEVROLET 2500 HD TRUCK. THEY ARE ALSO BROKEN ON MY SONS 2004 GMC 2500 HD AND MY BROTHERS 2005 GMC 2500HD. SOMETHING IS WRONG WITH THAT AND SOMETHING SHOULD BE DONE BEFORE THEY CATCH FIRE.

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM

RECENTLY I DEVELOPED AN EXHAUST LEAK NEAR THE FRONT OF THE EXHAUST SYSTEM NEAR THE ENGINE. UPON INSPECTION I FOUND THE BACK MANIFOLD BOLT HAD BEEN BROKEN OFF ON THE DRIVERS SIDE (I MAY ALSO HAVE A BROKEN BOLT ON THE PASSENGER SIDE AS WELL). I TOOK THE VEHICLE TO MY LOCALLY RESPECTED MECHANIC WITH THE INTENTION OF HAVING THE BROKEN BOLT REMOVED AND A NEW ONE INSTALLED. I WAS NOTIFIED THAT THIS WAS A COMMON PROBLEM WITH THESE GM VEHICLES (2004 SILVERADO 2500HD). I WAS FURTHER INFORMED THAT THERE WAS NO WAY THE REPAIR WOULD BE SIMPLE DUE TO THE FACT THERE WAS NO PRACTICAL MANNER IN WHICH TO EXTRACT/DRILL OUT THE BROKEN BOLT FOR REPLACEMENT. I WAS TOLD THE HEAD WOULD NEED TO BE REMOVED IN ORDER TO EFFECT THE REQUIRED REPAIR WHICH WOULD COST SOMEWHERE BETWEEN $700-$1000. THIS REPAIR IS NOT COST EFFECTIVE TO ME FOR WHAT IS PROBABLY A $3.00 BOLT. RESEARCHING THIS ISSUE ON THE INTERNET I FOUND OUT IT IS IN FACT A PROBLEM WITH THESE VEHICLES DATING BACK TO 1999. WHY HAS GM NOT BEEN REQUIRED TO REPAIR THIS ITEM AT NO COST TO THE OWNER IF IT IS THIS WIDESPREAD.
