ANTIFREEZE LEAK; LEAD TO REPLACEMENT OF LOWER INTAKE MANIFOLD GASKET (VERY COSTLY) ABOUT 4 YEARS AGO. NEEDS REPLACING AGAIN. DEALERSHIP WARNS OF EXCESSIVE ENGINE DAMAGE DUE TO ANTIFREEZE IN THE MOTOR OIL. *NM
LENS COVER OVER THE HEADLIGHTS FELL OUT OF BOTH HEADLIGHTS ON SEPERATE OCCCASIONS. I HAD TO BUY THE WHOLE HEADLIGHT ASSEMBLY. I WAS DRIVING DOWN THE ROAD AND THEY JUST FELL OUT AND BROKE ON THE ROAD. WE CURRENTLY HAVE A PROBLEM WITH IT OVERHEATING HAVE REPLACE THERMOSTAT AND WATER PUMP STILL HAVING SAME PROBLEM. NOT FIXED YET. THE POWER SLIDING DOOR ALARMS THAT IT IS OPEN FOR NO APPARENT REASON. THE DOOR HAS NOT OPENED AND CLOSED BY THE POWER FOR SEVERAL MONTHS. IT HAS TO BE MANNAULLY OPENED. WE HAVE ALSO REPLACED THE BOTH AIR SHOCKS IN THE REAR OF THE VAN. CAN'T GET THE RADIATOR CAP FROM RADIATOR HAVEN'T BEEN ABLE TO REMOVE SINCE IT WAS BOUGHT.
A/C HEAT - AIR CONDITIONING / HEAT UNIT IN REAR OF VAN FAILED IN 2001. HAVE NOT ATTEMPTED TO HAVE IT REPAIRED TO DATE. A/C AND HEAT IS OK FRONT. BODY - PASSENGER AUTOMATIC SLIDING DOOR. RATTLED ALMOST FROM THE DAY WE BOUGHT THE CAR. IT ALSO AT TIMES WOULD NOT CLOSED (IN PARK). IT WOULD CLOSE AUTOMATICALLY UNTIL IT TOUCHED THE CAR BODY THEN WOULD RE-OPEN. THEY REPLACED THE POWER SLIDING DOOR UNLATCH ACTUATOR UNDER A RECALL. ENGINE - STARTING AT 48,000 MILES THE CHECK ENGINE LIGHT WOULD START TO BLINK WHEN DRIVING, IMMEDIATELY THE VAN WOULD START TO RUN VERY ROUGHLY AND HAVE POOR ACCELERATION. LIGHT WOULD THEN STOP BLINKING AND STAY "ON". THEN OVER A PERIOD OF ABOUT AN HOUR RUNNING TIME WOULD TURN OFF. THIS WOULD HAPPEN EVERY OTHER MONTH OR SO FOR A DAY. EVENTUALLY -WE WERE TOLD IT WAS THE FUEL INJECTORS (AT 56,000 MILES). WE REPLACED THOSE 2000 MILES AGO AND THE SAME PROBLEM JUST APPEARED AGAIN TODAY (JULY 31, 2003) AUGUST UPDATE: HAD COOLANT LOSS - IT WAS THE GASKET WHICH HAD TO BE REPLACED AT ABOUT $750.. MOST OF IT LABOR TO GET TO THE DARNED THING.
I HAVE A 1997 PONTIAC MONTANA MINIVAN. I HAVE BEEN TOLD THAT I HAVE THE DREADED INTAKE MANIFOLD LEAK. IT APPEARS THAT THIS IS A HUGE PROBLEM WITH THE 3.4 LITER ENGINE. *JB
INTAKE MANIFOLD GASKET LEAK. MR. *AK
BLOWN HEAD GASKET AFTER ONLY 50,000 MILES. NOT TO MENTION I HAD A BLOWN MANIFOLD GASKET 6 MONTHS BEFORE THIS!. *NLM
CONSUMER STATES THE VEHICLE LEAKS FUEL FROM THE ENGINE. *TS
INTAKE MANIFOLD GASKET IS DAMAGED YET NO PARTS AVAILABLE THROUGHOUT US. IS THIS A KNOWN FACT TO GM? IS THIS A RECALL ITEM. MY VAN NOW OVERHEATS AND CANNOT BE REPAIRED DUE TO LACK OF PARTS.*AK
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
