1998 Pontiac Bonneville

POSSIBLE DEFECTIVE ENGINE PART. PONTIAC 3.8L INTAKE MANIFOLD FAILURE CAUSING POSSIBLE CATASTROPHIC ENGINE FAILURE IF ENGINE VAPOR LOCKS AT TIME OF FAILURE WHILE ENGINE IS RUNNING. THIS PART FAILED ON MY VEHICLE AND THE INDEPENDANT REPAIR SHOP I TOOK IT TOO ALREADY HAD NEEDED REPAIR PART ON HAND BECAUSE (AS THEY STATED) THERE ALWAYS FIXING THIS ENGINE FOR THIS PROBLEM. I FOUND 1 TSB ON YOUR SITE #01060007A BUT IT WAS 2.5 YEARS AGO. I SPOKE WITH A GM REPRESENTATIVE BUT WAS ADVISED THE COULD NOT COMMENT ON IF THIS WAS A PROBLEM OR NOT.*AK

ENGINE INTAKE MANIFOLD AND GASKET FAILED WHILE CAR WAS BEING DRIVEN IN RUSH HOUR TRAFFIC, ON A MAJOR HIGHWAY, WITH TRAFFIC MOVING AT A SPEED OF APX 70 MPH. THIS MANIFOLD AND GASKET FAILURE RESULTED IN THE ENGINE STALLING, FURTHER CAUSING A LOSS OF STEERING AND BRAKING CONTROL. SEVERAL CARS SWERVED AND SKIDDED TO AVOID COLLISION WITH OUR DISABLED CAR. THE CAR WAS TOWED TO THE SELLING PONTIAC DEALER. THE INTAKE MANIFOLD AND GASKET HAD FAILED, AND THE COST OF REPAIR WAS $1,036.00. I HAVE FOUND OUT THAT THE INTAKE MANIFOLD AND GASKET HAD BEEN IMPROPERLY DESIGNED, AND THAT A HIGH FAILURE RATE IS OCCURRING ON GM V-6 3.8 ENGINES. I CONTACTED GM, AND THEY WILL NOT HELP WITH THIS. THERE ARE MANY WEB SITES THAT VERIFY THOUSANDS OF OTHER FAILURES. ALSO, A GM SERVICE MANAGER THAT I SPOKE WITH AT A DIFFERENT DEALERSHIP HAS ACKNOWLEDGED THAT THERE IS A PROBLEM, AND THAT MANY TIMES, THE ENGINES FAIL DUE TO THIS PROBLEM, RESULTING IN A $5,000.00 REPLACEMENT OF THE ENTIRE ENGINE. THIS PROBLEM NEEDS TO BE ADDRESSED, AS GM IS LAUGHING AT THE PUBLIC ON THIS ONE. WHO OF US HAS THE RESOURCES TO CHALLENGE THEM, AND THEY COULD CARE LESS IF WE EVER BUY ANOTHER CAR FROM THEM.

MY COMPLAINT IS THAT I AM ABOUT TO PUT MY 4TH AND 5TH INTAKE MANIFOLD & MANIFOLD GASKET, RESPECTIVELY, ON MY 1998 PONTIAC BONNEVILLE. I WAS DRIVING DOWN HIGHWAY 55 AT 70 MPH WHEN MY ENGINE DIED, BECAUSE MY MANIFOLD KEEPS CRACKING!! BECAUSE MY ENGINE DIED, IT KEPT BLOWING AND FORCING ANTIFREEZE DOWN MY INTAKE AND FILLING MY CYLINDERS WITH WATER AND ANTIFREEZE, CAUSING A VAPOR LOCK!!! THIS WAS TERRIBLE, BECAUSE WHEN I TRIED TO RESTART THE CAR IN NEUTRAL GOING 70 MPH, WITH 20-25 CARS AROUND ME AND 3-5 SEMI TRUCKS, THE ENGINE WAS LOCKED UP!!!!! BECAUSE OF THIS 'VAPOR LOCK UP' OF THE ENGINE, I LOST CONTROL OF MY CAR!!! I HAD NO POWER STEERING, NO POWER BRAKES, NO CONTROL TO BE ABLE TO AVOID A 20-25 CAR PILE UP, WITH TENS TO HUNDREDS BEING INJURED!!!!!!!!! GM NEEDS TO DO A COMPLETE RECALL OF ALL 3.1, 3.4 & 3.8 V6 ENGINES MADE WITH PLASTIC MANIFOLDS AND PLASTIC GASKETS!!!! GM NEEDS TO REPLACE THEM WITH THE ALUMINUM MANIFOLDS AND RUBBER GASKETS THEY USED TO PLACE ON ALL ENGINES MANUFACTURED SINCE THESE CHANGES WHICH I BELIEVE IS 1996!!!!! NEXT, AFTER ALL THESE MANIFOLDS AND GASKET FAILURES ON MY CAR, OF WHICH I CHANGE THE OIL EVERY 2000 MILES AND HAVE DOCUMENTATION TO SUPPORT MY OIL CHANGES, THE ANTIFREEZE HAS EATEN MY BEARINGS AND CRANKSHAFT MAINS AND ROD BEARINGS AND MY ENGINE IS KNOCKING BADLY!!! A FAIR RESOLUTION WOULD BE FOR GM TO GIVE ME(FREE OF ANY CHARGE), A NEW ENGINE TO REPLACE THE ONE THEY DAMAGED, WITH THEIR DEFECTIVE PARTS, WORKMANSHIP AND MANUFACTURING DESIGN CHANGES. IF THERE IS NO PROBLEM, THEN WHY HAS GM ISSUED A VERY EXPENSIVE TSB? TO CHANGE THE DESIGN, COMPONENT AND INSTALLATION OF THESE DEFECTIVE PARTS???????
