THERE ARE 313 COMPLAINTS ON THIS WEBSITE AS OF TODAY CONCERNING THE 1998 PONTIAC BONNEVILLE. OUT OF THOSE 313 REPORTS, AT LEAST 132 ARE 100 PERCENT RELATED TO THE PLASTIC MANIFOLD FAILURE WHICH CAUSES THE ENGINE TO OVERHEAT TO CATASTROPHIC RESULTS. I HAVE HAD TO REPLACE THE ENGINE ON MY VEHICLE TWICE WITHIN 4 YEARS. GMC IS REFUSING TO ACKNOWLEDGE THIS ISSUE AND IT IS A SHAME THAT THE ALMIGHTY DOLLAR IS MORE IMPORTANT THAN INTEGRITY,HONOR AND PEOPLE'S LIVES. WHAT HAPPENED TO PRIDE IN WHAT YOU MANUFACTURE?SHAME ON GMC!!! *JB

IT IS VERY OBVIOUS THAT GMC IS REFUSING TO ACKNOWLEDGE THE APPARENT DEFECTS WITH THE PONTIAC BONNEVILLE. MY ENGINE LOCKED UP IN JULY 2001 WITH NO PRIOR WARNING. THE MECHANIC THAT REPAIRED THE CAR TOLD ME THAT WATER AND RADIATOR FLUID WAS COMING OUT OF THE ENGINE AND THE CHEAP PLASTIC PLENTUM HAD TO BE REPLACED. NOW,THE SAME EXACT PROBLEM HAS OCCURRED ONCE AGAIN ON 11/07/2005. THE CAR WAS ONLY GOING 35 MPH WHEN THE ENGINE OVER-HEATED AND THIS TIME IT IS COSTING ME 2,321.00! I FEEL SOMETHING SHOULD BE DONE BY GMC OR RESEARCH SHOULD BE DONE TO RESOLVE THIS PROBLEM. IT IS EXTREMELY APPARENT THAT THIS IS A DEFECT IN ALL 1998 PONTIAC BONNEVILLES AND SOMETHING SHOULD BE DONE TO ADDRESS THE PROBLEM. I HAVE 3 CHILDREN AND CANNOT AFFORD A NEW CAR NOR CAN I AFFORD TO RE-BUILD OR RE-PLACE MY ENGINE EVERY 3-4 YEARS. *JB
