WE HAVE 1999 MONTANA WITH APPOX. 57,000 MILES AND THE INTAKE GASKET HAS FAILED. I HAVE BEEN A DI-HARD PONTIAC/GMC BUYER ALL MY LIFE, BUT AFTER MY LAST TWO VANS WE DECIDED TO PURCHASE A FORD. I HAD NOTHING BUT TROUBLE WITH MY 1996 TRANSPORT AND TRADED IT FOR OUR 1999 MONTANA. I LOVE MY MONTANA, BUT THE CARBON KNOCKING IN EMBARRASSING AND NOW WE ARE BEING CHARGED OVER $600.00 FOR A PROBLEM THAT GM KNOWS EXISTS. I WAS ABOUT TO PURCHASE ANOTHER VEHICLE IN THE GM FAMILY UNTIL THIS WEEK. THEY ARE OFFERING $1500 IN "LOYALTY CASH" WE HAVE BEEN LOYAL! WHERE IS GM'S LOYALTY!!! MY NEXT CAR WILL MOST LIKE BE A NON-GM MODEL THANKS TO GM'S LOYALTY!!!!!*AK
WE HAVE ONLY HAD OUR VAN A YEAR. WE HAVE HAD PROBLEMS SINCE WE GOT IT. ONE THING AFTER ANOTHER. FIRST COOLANT LEAKING, ELECTRIAL PROBLEMS, INTAKE GASKET LEAKING. REPLACED 11/05. MOTOR FAILED 1/05. DOOR MAILFUNCTION.*AK
THE CONSUMER STATES THE INTAKE MANIFOLD HAS MALFUNCTIONED. AS A RESULT THE COOLANT LEAKS INTO THE OIL AND THE CONSUMER IS NOW CONCERNED THAT THE ENGINE COULD FAIL. THE CAUSE HAS YET TO BE DETERMINED. PLEASE PROVIDE ADDITIONAL INFORMATION. *NM
WE HAVE A 1999 PONTIAC MONTANA THAT WE PURCHASED NEW FROM A LOCAL DEALER IN SOUTH BEND IN. I NOTICED OIL AND ANTIFREEZE GOING DOWN AND TOOK THE VAN TO A GARAGE.

WE HAVE A 1999 PONTIAC MONTANA THAT WE PURCHASED NEW FROM A LOCAL DEALER IN SOUTH BEND IN. I NOTICED OIL AND ANTIFREEZE GOING DOWN AND TOOK THE VAN TO A GARAGE. HE SAID THAT PONTIAC SHOULD MAKE THE REPAIRS BECAUSE THE LEAK WAS CAUSED BY A MANIFOLD GASKET PROBLEM I TOOK IT TO THE LOCAL DEALER AND TALK TO HIM ABOUT REPAIRS. AT FIRST HE SAID THE REPAIRS WOULD BE AROUND $1500.00. I TOLD HIM THAT IT WOULD BE CHEAPER TO BUY ANOTHER VEHICLE. HE SAID PROBABLY. A REAL SMART ALECK. I TOLD HIM THAT THERE WAS, AT THAT TIME, 30,0000 MILES ON THE VEHICLE. HE TALKED TO THE MANAGER AND THEY CAME UP WITH A PRICE AROUND $600.00. I TOLD THEM TO DO IT. THE FINAL PRICE WAS JUST UNDER $400.00. NOW I FIND THAT IT IS LEAKING A LITTLE AGAIN AND THE WATER PUMP IS LEAKING, TOO. I HAD A PRIVATE GARAGE CHANGE THE WATER PUMP AND PROBABLY WON'T GET THE MANIFOLD GASKET REPLACED AT THIS TIME. I ALSO HAD THE BRAKES CHECKED AND FOUND THAT THE REAR WHEEL CYLINDERS WERE LEAKING. THAT IS ANOTHER COST ON THIS 1999 PONTIAC MONTANA VAN. THE DRIVERS DOOR NEEDS A REPAIR TO SOME OF THE MECHANISM IN THE WINDOW AND IT WILL COST AROUND $500. I HAVE HEARD THAT THIS WINDOW PROBLEM IS COMMON WITH THESE VEHICLES. I HAVE REACHED THE POINT OF GETTING RID OF THE VAN AND GOING TO SOMETHING BESIDES A GM PRODUCT. THE VAN HAS 32,000 MILES ON IT NOW AND I SHOULDN'T BE SEEING ALL OF THIS HIGH DOLLAR REPAIRS ON IT. *AK
MY 1999 MONTANA STARTED LEAKING ANTIFREEZE RAPIDLY. TWO DIFFERENT SERVICE CENTERS STATED IT WAS A WORN GASKET IN THE LOWER INTAKE. REPAIRS CAME TO $604. KNOW THIS HAS BEEN A PROBLEM FOR MANY VEHICLES WITH THE 3.4 ENGINE. I NOTICED THE LEAK AT 72,000 MILES BUT HAVE HAD TO ADD COOLANT MANY TIMES OVER THE LAST 2.5 YEARS.*AK
VEHICLE OVERHEATED ON HIGHWAY- WITH KIDS IN CAR EN ROUTE TO FAMILY OUTING.*AK
LOW COOLANT ICON LIT UP ON DASH AT 15000 MILES.DEALER SAID INTAKE MANIFOLD GASKET FAILED AND IT WAS REPLACED UNDER WARRANTY. AT 51500 MILES LOW COOLANT ICON LIT UP ON DASH. DEALER SAID INTAKE MANIFOLD GASKET FAILED AND IT WAS REPLACED AT A COST OF 503.00 DOLLARS TO MYSELF. *LA
INTAKE MANIFOLD GASKET LEAK. NEEDED REPLACEMENT AFTER LOSS OF COOLANT INTO OIL. EVEDENTLY A COMMON DEFECT. $700. TRANSMISSION PROBLEMS AT 24K MILES. DEALER FIXED. AT 79K MILES NEEDED REPLACEMENT FOR $3300. *AK
I HAVE NOTICED MY COOLANT LEVEL IS DOWN VERY OFTEN WITH THE "LOW COOLANT" LIGHT COMING ON, AS WELL. ACCORDING TO MY GM DEALER THE LOWER INTAKE MANIFOLD IS LEAKING COOLANT FROM MY 99 MONTANA WITH ABOUT 60K MILES. DEALER HAS INDICATED THE REPAIR OF THIS GASKET TO BE OVER $700 WHICH IS OUTRAGEOUS. I HAVE OWNED ABOUT 12 CARS IN…

I HAVE NOTICED MY COOLANT LEVEL IS DOWN VERY OFTEN WITH THE "LOW COOLANT" LIGHT COMING ON, AS WELL. ACCORDING TO MY GM DEALER THE LOWER INTAKE MANIFOLD IS LEAKING COOLANT FROM MY 99 MONTANA WITH ABOUT 60K MILES. DEALER HAS INDICATED THE REPAIR OF THIS GASKET TO BE OVER $700 WHICH IS OUTRAGEOUS. I HAVE OWNED ABOUT 12 CARS IN MY LIFETIME AND NOT ONE HAS HAD A PROBLEM LEAKING COOLANT OUT AROUND THE INTAKE MANIFOLD GASKET. AFTER REVIEWING OTHER COMPLAINTS ON THE NHTSA WEBSITE, IT IS OBVIOUSLY A DEFECT IN THIS MODEL ENGINE AND CONSUMERS SHOULD BE REIMBURSED, IF NOT FULLY, THEN PARTIALLY FOR THE REPAIRS. A $700+ REPAIR BILL IS WAY TOO MUCH TO EXPECT THE CONSUMER TO PAY OUT FOR THIS DEFECT. *AK
