THIS TRUCK IS EQUIPPED WITH THE 6.0L VORTEC V8 ENGINE AND HAS DEVELOPED AN EXHAUST LEAK ON BOTH SIDES OF THE ENGINE AT THE MANIFOLD GASKETS! THE LEAK IS FROM THE PORTS WHERE THE BOLTS SECURING MANIFOLD TO CYLINDER HEAD ARE BROKEN! GM IS WELL AWARE OF THIS ISSUE, DOES NOT WANT TO RECALL THE ISSUE OR WARRANTY THE REPAIRS. THERE ARE THOUSANDS OF COMPLAINTS FROM OWNERS OF GM VEHICLES WITH V8 ENGINES INCLUDING THE 4.8L, 5.3L, 6.0L ENGINES. THIS IS A PROBLEM IN MANY OF WAYS, MOST IMPORTANTLY THAT TOXIC EXHAUST FUMES ARE EMITTING FROM UNDER THE HOOD AND CAN ENTER THE CAB OF THE VEHICLES! INSPECTION LAWS REQUIRE THAT EXHAUST FUMES EXIT THE VEHICLE BEHIND THE REAR WHEEL! THE OTHER PROBLEMS INCLUDE THE FACT THAT THIS LEAK WILL AFFECT READINGS TAKEN FROM THE UPSTREAM OXYGEN SENSORS AND CAN THEREFORE CAUSE CHECK ENGINE LIGHTS FOR CATALYTIC CONVERTER DEFICIENCIES TO SYSTEM LEAN CONDITIONS. ALSO HAVING AN EXHAUST LEAK WILL FAIL SAFETY INSPECTIONS AND EMISSIONS TESTING. GM IS VIOLATING EPA LAWS BY ALLOWING THIS TO GO ON! THIS PARTICULAR VEHICLE IS PAST DUE FOR INSPECTION AND EMISSIONS AS WE ARE A PENNSYLVANIA RESIDENT AND I CANNOT AFFORD TO HAVE THIS FIXED AT A DEALER! *TR

2005 CHEVY SILVERADO 2500 DIESEL TRUCK ON FREEWAY ON 01/25/2010 AND THE TRUCK IMMEDIATELY LOST POWER WHILE PULLING A TRAILER. VERY DANGEROUS. CONSUMER NEVER MADE AWARE OF TECH BULLETIN OR PROBLEM. TSB #05-06-04-047B INJECTION HARASS. NHTSA #10017389. THE TRUCK HAS BEEN TAKEN TO DEALER FOR OTHER RECALL NOTICES AND DEALERS NEVER ADDRESSED THE PROBLEM AND SHOULD HAVE BEFORE WE WERE STUCK OUT IN THE MIDDLE OF THE DESERT AND HAD TO GET THE VEHICLE AND 5TH WHEEL TRAILER TOWED. THE CONSUMERS SHOULD BE NOTIFIED OF THIS PROBLEM AND CHEVY DEALERS SHOULD FIX PROBLEM WITH THE INJECTION HARNESS BECAUSE WHEN A VEHICLE LOSES POWER ON THE FREEWAY IT IS DANGEROUS. *TR

THE BLOWER MOTOR (FOR HEAT & AIR CONDITIONING) STOPPED WORKING AND WAS REPLACED ON OUR 2005 CHEVY SILVERADO 2500. WITH IN A YEAR IT STOPPED WORKING AGAIN AND UPON INSPECTION WE ALONG WITH RAYMOND CHEVROLET IN ANTIOCH, ILLINOIS NOTICED THAT THE BLOWER MOTOR WAS BURNED OUT AND THE RESISTER HARNESS WAS BURNT. AS IF IT WAS ON FIRE. THANKFULLY NO FURTHER DAMAGE WAS DONE BESIDES THE BURNING OF THE MOTOR, WIRES AND HARNESS. THIS WAS REPLACED AGAIN ON 10-30-08 AND NOW ON 06-23-09 AGAIN THE MOTOR HAS BURNT OUT AGAIN. THE DEALERSHIP SERVICE DEPARTMENT HAD NO EXPLANATION WHY THIS HAS HAPPENED 3 TIMES AND BEING AWARE OF THIS WE MAKE SURE NOTHING IS CLOSE TO THE DASH PREVENTING A SPREAD OF FIRE IN CASE IT WERE TO HAPPEN AGAIN, WHICH IT HAS. *TR

THE ENGINE OIL COOLER LINES AND THE TRANSMISSION COOLER LINES LEAK AT THE CRIMP WHERE THE RUBBER HOSE AND METAL LINES CONNECT. AFTER DOING RESEARCH ONLINE ABOUT THIS I HAVE DISCOVERED IT IS A VERY COMMON PROBLEM. SOME PEOPLE HAVE REPLACED THESE LINES MULTIPLE TIMES ONLY TO HAVE THEM LEAK A SHORT WHILE LATER. FOR THOSE OF US WHOSE VEHICLES ARE OUT OF WARRANTY THIS CAN BE VERY COSTLY. I WOULD ALSO THINK THAT TRANSMISSION FLUID AND MOTOR OIL CONTACTING HOT SURFACES LIKE AN EXHAUST POSE A FIRE HAZARD. AT THE VERY LEAST THE LEAKING OIL IS AN ENVIRONMENTAL HAZARD. I HAVE PURCHASED OIL COOLER LINES AND AM REPLACING THEM TOMORROW BUT I AM HAVING TROUBLE FINDING TRANSMISSION LINES. *TR
