2000 Pontiac Montana engine and engine cooling problems

“2000 PONTIAC MONTANA INTAKE GASKET FAILED...I'VE READ ALL THE OTHER COMPLAINTS AND JUST WANTED TO ADD MINE. I CALLED GM AND THEY SAID THEY DID NOT HAVE ANY COMPLAINTS RELATIVE TO THIS PROBLEM, AND THERE WAS NO RECALL EITHER. I HAVE NEVER USED ANYTHING BUT DEXCOOL IN THIS VAN, NOW IT IS GOING TO COST ME TO HAVE IT FIXED FOR FOLLOWING DIRECTIONS....NOW I UNDERSTAND WHY PONTIAC IS BEING DROPPED BY GM THEY WOULD NOT BE ABLE TO PAY ALL THE REPAIR BILLS IF THE OWNED UP TO THEIR MISTAKE...GOODBYE PONTIAC!!!!!!!! *TR”

“I OWN A 2000 PONTIAC MONTANA THAT NEEDS AN INTAKE GASKET REPLACED. THE COMPANY SPECIFICALLY ADVISES THAT NO OTHER COOLANT IS TO BE USED IN THIS VAN BUT DEXCOOL. I NEVER USED A DIFFERENT PRODUCT THAN DEXCOOL. NOW DEXCOOL HAS DESTROYED THAT GASKET. MY CAR IS LEAKING FLUIDS AND BARELY HEATS. COST FOR REPAIR IS OUTLANDISHLY EXPENSIVE. THE RECOMMENDATIONS BY GM WERE FOLLOWED AND THEY WERE WRONG! THIS IS A MANUFACTURING ISSUE, NOT A CONSUMER ONE. THE ONUS SHOULD BE ON GM TO RECALL AND REPAIR THE INTAKE GASKET IMMEDIATELY! THEY HAVE GOTTEN AWAY WITH THIS PROBLEM FOR YEARS AND EVERY MONTANA HAS THIS ISSUE. PLEASE HELP. THANK YOU. *TR”

“MANIFOLD INTAKE GASKET FAILURE AT 125,000 MILES REPLACED AT COST OF $1100, MECHANIC TOLD ME THIS WAS COMMON PROBLEM FOR VEHICLE, BECAUSE ORIGINAL GASKET WAS PLASTIC AND FAILED OFTEN. WOULD LIKE AT LEAST PARTIAL REFUND FOR REPAIR. *TR”

“2000 PONTIAC MONTANA; 3.4LTR 6CYL: "SERVICE ENGINE" SOON LIGHT PROMPTED SERVICE VISIT. TECH TOLD US THAT CODES INDICATED THAT INTAKE MANIFOLD GASKETS HAD FAILED AND THAT ENGINE OIL AND COOLANT WERE LEAKING. SUCH LEAKAGE CAUSED OIL CONTAMINATION OF THE COOLANT AS WELL AS COOLANT CONTAMINATION OF THE OIL. TECHNICIAN FURTHER COMMENTED THAT THIS WAS AN EXTREMELY COMMON PROBLEM WITH THE GM 3.4 LTR 6CYL ENGINE AND HAD BEEN KNOWN TO GM FOR SEVERAL YEARS, BUT HAD NEVER BEEN FIXED. REPAIR COSTS APPROX $800 AND MUST BE DONE SINCE THE RELATED CODES WILL CAUSE FAILURE OF ANNUAL EMISSIONS TESTING AND VEHICLE LICENSE TAGS WILL NOT BE ISSUED. INTERNET RESEARCH ON THIS DEFECT CONFIRMED THAT PROBLEM IS WIDESPREAD AND WELL KNOWN. GM SHOULD BE FORCED TO RECALL ALL AFFECTED VEHICLES. *TR”

“BLOWN HEAD GASKET AT 107K MILES IN A 2000 PONTIAC MONTANA. THIS IS AN EXPENSIVE REPAIR CAUSED BY FAULTY DESIGN OR THE USE OF DEX COOL. THIS IS ONE OF MANY FAILURES ON THE VEHICLE. *TR”

“I HAVE 3 CHILDREN, ONE DISABLED. I SHOULD HAVE KNOWN FROM DAY 1 WHEN THE MANUAL SLIDING DOOR BROKE TWO WEEKS AFTER PURCHASE. ALMOST KILLED MY DISABLED CHILD WHEN IT SPRANG OPEN ON HIM. DEALER, SAID HE BROKE IT, A CHILD WITH FULL BODY MUSCLE DISORDERS WHO CAN'T LIFT A BRICK. NOW WE HAVE HAD UNENDING PROBLEMS WITH THE ENGINE, COOLANT LEVELS, THE CAR SMELLS LIKE BURNT PLASTIC OFTEN, TIMES WHEN I WENT TO START IT, NOTHING HAPPENED. NOW I AM TOLD THAT THE ENGINE WILL SEIZE SOON. INTERESTING SINCE I ALWAYS CHANGED THE FLUIDS ON TIME AND I HAVE ONLY OWNED IT FOR 5 YEARS. BOTH SIDE DOORS DO NOT WORK, AUTOMATIC WORKS SOMETIMES, MANUAL COMES OFF THE TRACK. ONE OF THE REAR PASSENGER SEATS DOES NOT FOLD PROPERLY. THE CAR OFTEN FEELS AS THOUGH IT HAS "BAD GAS" JERKING BACK AND FORTH WHILE DRIVING IT. I AM AFRAID, I HAVE THREE KIDS IN THE CAR USUALLY. I NEED A CAR AND NOW WITH NO MONEY AND NO ABILITY TO BUY A NEW ONE, I AM TOLD THAT THE CAR WILL SEIZE IF I DO NOT SPEND $4000 TO REPLACE THE ENGINE. I AM GETTING A SECOND OPINION BUT FROM WHAT I AM READING, IT SEEMS FEUDAL. SHAME ON GM!! WHY WASN'T THIS CAR RECALLED??? THIS IS A VAN, A FAMILY CAR!!! YOU WANT TO KILL…”
