ENGINE
THE ENGINE STARTED MISSING ON 1CYLINDER, THEN SHOWED AN ENGINE WARNING LIGHT. THE INSTRUMENT PANEL ALSO SHOWED A REDUCED POWER WARNING. THE TRUCK WAS TAKEN TO MY LOCAL GARAGE, AND SUBSEQUENT INSPECTION SHOWED NO COMPRESSION IN #1 CYLINDER. THE TRUCK WAS THEN TOWED TO FLEMINGTON BUICK CHEVROLET GMC. INSPECTION THERE WAS DIAGNOSED AS BURNT VALVES OR FAILED VALVE SEATS. THERE ARE SERVICE BULLETINS ON 2005 AND 2006 COLORADOS FOR VALVE AND VALVE SEAT PROBLEMS. THE SERVICE PERSONNEL AT THE DEALERSHIP WERE HONEST AND CONSIDERATE TO INFORM ME OF THE BULLETINS ON THE OLDER MODELS, AND THAT WHILE THERE WERE NO BULLETINS ON 2007 COLORADOS, MINE WAS NOT THE ONLY ONE TO HAVE THE SAME TYPE OF VALVE PROBLEMS. THE 2005 AND 2006 MODELS WERE REPAIRED UP TO 100,000 MILES FREE OF CHARGE. AS THERE ARE NO SERVICE BULLETINS OR RECALLS ON 2007 MODELS, CHEVROLET HAS OFFERED TO PAY ONLY HALF OF THE REPAIR COSTS. MY VEHICLE IS NOW 5 MONTHS PAST WARRANTY WITH 75000 MILES AND WAS BOUGHT USED OFF LEASE. CHEVROLET HAS OFFERED TO PAY HALF THE REPAIR COST OF APPROXIMATELY 2800 DOLLARS BECAUSE THEY SAY THIS WAS UNUSUAL. I FEEL THEY SHOULD PAY THE WHOLE COST AS THIS REPAIR IS A CONTINUANCE OF THE 05, 06 PROBLEM. IS THERE ANYWAY TO CHECK HOW MANY 2007 COLORADOS HAVE VALVE PROBLEMS SIMILAR TO THE 05, 06 VALVE AND CYLINDER HEAD BULLETINS. *TR
