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 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! *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

TL* THE CONTACT OWNS A 2004 CHEVROLET SILVERADO 2500 HD. THE CONTACT STATED THAT WHILE TOWING A TRAILER AT APPROXIMATELY 55 MPH, A CLICKING NOISE WAS HEARD FROM THE ENGINE AND THE ENGINE EXPLODED. THE CONTACT ALSO OBSERVED SMOKE RISING FROM THE ENGINE DURING THE FAILURE. THE VEHICLE WAS TOWED TO AN INDEPENDENT REPAIR SHOP WHERE THE CONTACT WAS INFORMED THAT THE ENGINE EXPLODED AND ALL OF ITS COMPONENTS WERE MELTED. THE VEHICLE WAS THEN TOWED TO AN AUTHORIZED DEALER WHERE THE FAILURE WAS CONFIRMED AND THE CONTACT WAS ADVISED THAT THE ENGINE WAS DESTROYED. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE, BUT OFFERED NO ASSISTANCE. THE FAILURE MILEAGE WAS 55,000.

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

TL* THE CONTACT OWNS A 2004 CHEVROLET SILVERADO 2500 HD DIESEL. THE CONTACT STATED WHILE DRIVING, THE CHECK ENGINE LIGHT ILLUMINATED AND THE VEHICLE STALLED. THE CONTACT MENTIONED THE FAILURE HAPPENED SEVERAL TIMES. THE VEHICLE WAS TAKEN TO THE DEALER WHO WAS UNABLE TO DIAGNOSE THE FAILURE. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE BUT STATED THEY WOULD CONTACT HIM AT A LATER DATE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS UNKNOWN AND THE CURRENT MILEAGE WAS 124,869.

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
