1999 Oldsmobile SILHOUETTE: complaints, problems and recalls

I OWN A 1999 OLDSMOBILE SILHOUETTE WITH 52,000 MILES. I BROUGHT IT TO THE LOCAL DEALER BECAUSE OF A KNOCKING NOISE ON COLD STARTUP. DIAGNOSED AS A FAILED INTAKE MANIFOLD GASKET, COST TO REPAIR APPROX $900.00. ON DISASSEMBLY, DEALER CONTACTED ME WITH INFORMATION THAT THE ENGINE INTERNALS WERE SO BADLY FOULED (SLUDGE AND DEPOSITS) THAT THE HYDRAULIC LIFTERS REQUIRED REPLACEMENT. I ASKED WHAT COULD HAVE CAUSED THIS SITUATION, SINCE THE VAN HAS ALWAYS GOTTEN REGULAR OIL CHANGES EVERY 3000 MILES, WITH NEW FILTER AND CORRECT OIL, AND I DON'T KNOW…

I OWN A 1999 OLDSMOBILE SILHOUETTE WITH 62,000 MILES. I TOOK THE VAN TO A LOCAL DEALER BECAUSE OF A KNOCKING NOISE ON COLD STARTUP. THE DEALER DIAGNOSED THE PROBLEM AS A FAILED INTAKE MANIFOLD GASKET. THE FAILED GASKET RUINED THE HYDRAULIC LIFTERS AND HAD TO BE REPLACED. THE TOTAL BILL WAS $1500. THE VAN HAD REGULAR MAINTENANCE (OIL, FILTERS, ANITFREEZE CHECKED) EVERY 3000 MILES. THIS SEEMS TO BE A COMMON PROBLEM WITH GM VEHICLES AND DEXCOOL SYSTEMS. THIS COULD HAVE BEEN A MAJOR SAFETY ISSUE HAD THE ENGINE FAILED WHILE DRIVING.*JB

AFTER READING THE OTHER COMPLAINTS ON POWER TRAIN, AUTO TRANSMISSION I NOTICED ALL THE SAME ISSUES. WE TOO EXPERIENCED HEAVY JERKING OVER THE LAST TWO YEARS AT INTERMITTENT TIMES AND REPORTED TO THE DEALER WHO COULD NOT REPEAT THE OCCURRENCE AND TOOK NO ACTION. DREHER HOLLOWAY. AT 48,000 MILES, THE TRANSMISSION FAILED AND THE DEALER CLOSEST TO THE INCIDENT, MERRIMACK STREET GARAGE, RECOMMENDED REPLACEMENT, NOT REPAIR. RENTAL CAR AND REPAIR, ALMOST $4000. GM IS NOT COVERING THE COST OR ADMITTING ANY OWNERSHIP OF THE PROBLEM. DREHER HOLL…
