COMPLAINT ON GM EXHAUST MANIFOLD BOLT DEFECT, INFERIOR BRAKE/ FUEL LINES. MINE IS A 2005 GMC. DEFECTIVE EXHAUST BOLTS AFFECT 12 MILLION GM TRUCKS FROM 1999 TO 2007. GM EXHAUST BOLTS ARE TO SMALL BRITTLE FOR SECURING EXHAUST MANIFOLDS. BOLTS SNAP OFF CAUSING EXHAUST LEAKS. TRUCKS NOT PASSING EMISSIONS AND DANGEROUS EXHAUST FUMES ENTERING THE DRIVERS COMPARTMENT OF THE VEHICLES WHILE DRIVING. I AND MY FAMILY GET A CARBON MONOXIDE HEADACHE WHEN I DRIVE IT AND HAVE HAD TO PULL OVER TO THE SIDE OF THE ROAD FEELING LIKE I WAS GOING TO PASS OUT, OPEN WINDOWS AND SIT UNTIL I FELT BETTER. I HAVE ALSO HAD PROBLEMS GETTING MY TRUCK TO PASS EMISSIONS DUE TO THE LEAKS AND THE LEAKS ARE CAUSING THE VEHICLES TO BE NONE EPA COMPLIANT BECAUSE OF O2 SENSOR ERRORS RESULTING IN FAILED EMISSION TEST. ALSO BRAKE AND FUEL LINES ARE NOT SUITABLE FOR NORTHERN STATES CAUSING BRAKE FAILURE WITH OUT WARNING, FUEL LINES ARE ALL RUSTED AND SWELLED IN DANGER OF BURSTING CAUSING FIRE WITHOUT WARNING. FORD AND OTHER VEHICLES I HAVE WORKED ON USE STAINLESS FUEL LINES AND LOOK LIKE NEW FOR LIFE OF VEHICLE. I HAVE ALSO SEEN OTHER MANUFACTURERS USE POWDER COATED BRAKE LINES ON THE ENTIRE VEHICLE AND 20 YEAR OLD VEHILCES SHOW NO RUST PROBLEMS. MY 2005 GMC FROM THE REAR END BRAKE HOSE TO THE WHEEL CYLINDERS THEY USED POWDER COATED BRAKE LINES. THOSE LINES LOOK LIKE NEW YET. GM KNEW THE POWDER COATED LINES WERE BETTER WHY DID THEY USE FAULTY GALVANIZED STEEL ON THE REST OF THE TRUCK? AS IT IS
