2000 Chevrolet Impala Engine

PREMATURE FAILURE OF INTAKE MANIFOLD GASKET CAUSING LEAKING OF COOLENT AND OIL MIX. *JB

FAILED MANIFOLD GASKETS INVOLVING ALOT OF CARS THAT GM IS INSUFFICIENTLY DEALING WITH OR TRYING TO KEEP FROM BECOMING A RECALL ON THE 2000 CHEVROLET IMPALA, 3.4 ENGINE.*AK

INTAKE MANIFOLD LEAK

THE PROBLEM IM NOTICING IS THAT MY CAR HAS DEXCOOL IN IT. I HAVE NOTICED IN THE PAST FEW MONTHS THAT MY CAR RUNS A LITTLE HOTTER THAN NORMAL. I HAVE ALSO NOTICED THAT THE COOLANT RESIVOIR LOOKS ALL CORRODED. IF YOU TAKE A LOOK AT THIS COOLANT IN THE RESIVOIR IT LOOKS REALLY CLUMPY AND SEEMS TO HAVE SOME RUST IN IT. I PURCHASED THIS VEHICLE IN 2000 . IT'S A 2000 CHEVY IMPALA. AND THE BAD THING ABOUT IT IS THAT CHEVY STANDS BY THIS COOLANT SAYING" IT'S GOOD FOR 115,000 OR SO OR 3 YEARS." I TOTALLY DISAGREE. I HAVE DID MY OWN RESEARCH ON THIS MATTER AND FOUND THAT THERE IS THOUSANDS OF PEOPLE THAT ARE HAVING TO PAY BIG$$$ TO HAVE REPAIRS DONE THAT ARE CAUSED BY THIS COOLANT CORRODING INSIDE THE ENGINE. CHEVY SHOULD RECALL THIS JUNK, SUCK UP ANY REPAIR COST. I NEED TO HAVE THIS PROBLEM ADDRESSED.

CONSUMER STATED TOOK VEHICLE IN FOR AN OIL CHANGE, AND WAS TOLD THAT THERE WAS OIL AROUND THE RADIATOR CAP. MECHANIC TOLD CONSUMER THAT MANIFOLD WAS LEAKING OIL, AND THAT THIS WAS AN INTERNAL OIL LEAK. ALSO, CONSUMER WAS TOLD THAT THE SEALS HAD TO BE REPLACED. IN ADDITION, MECHANIC TOLD CONSUMER THAT GMC ISSUED RECALL REGARDING INTAKE MANIFOLD LEAK, BUT THAT THIS VEHICLE'S WAS NOT INCLUDED DUE TO VIN. *AK.

ENGINE DIES SUDDENLY WITH NO WARNING. AT SPEEDS OF 40 - 60. VERY DANGEROUS SITUATION. SECOND 2000 IMPALA I HAVE HAD WITH THIS PROBLEM. PROBLEM STARTED WITH FIRST IMPALA AT 4000 MILES, NOW 50000 ON THIS ONE. LOTS OF OTHER 2000 IMPALAS WITH SAME PROBLEM BUT GM HAS NO FIX. *LA

THE VEHICLE OVER HEATED, HOWEVER THE DEALER WAS UNABLE TO DUPLICATE THE PROBLEM. *JB

VECHICLE STALLS AT FULL SPEED ON THE HIGHWAY, OR AT COMING TO STOPS. FEEL SLIGHT HESTIATION AND ROUGH IDYLING. HAD CAR COMPUTER UPGRADED/CALIBRATED TWICE, BUT STILL EXPERIENCING STALLS.

AFTER CAR HAS BEEN DRIVEN AND THE ENGINE IS HOT AND YOU ATTEMPT TO RESTART IT, IT JUST SHUTS BACK OFF. THERE IS NO SIGNIFICANT SOUND WHEN IT DOES THIS, IT JUST SHUTS DOWN AS IF THE IGNITION WAS TURNED OFF. IT NOW TAKES ABOUT 3-6 ATTEMPTS BEFORE THE CAR WILL START. IT HAS EVEN PROGRESSED TO SHUTTING OFF WHILE DRIVING, AGAIN NO SIGNS OF THE CAR BEING OFF UNTIL I NOTICED THE WHEEL WAS LOCKED UP. I HAVE BEEN BACK AND FORTH BETWEEN THE DEALER AND THE MANUFACTURER TO GET THE PROBLEM ADDRESSED. THE FACT THAT IT NOW SHUTS OFF WHILE DRIVING POSES A SERIOUS DANGER TO ME AND OTHER DRIVERS.

INTAKE GASKET LEAKING @ 60K ON A 2000 CHEVY IMPALA, 3.4 V6, GM DEALER INFORMED ME ON A $500 REPAIR BILL AND NOTED THAT THIS IS A COMMON PROBLEM, BUT NO RECALL. GM NEEDS TO HAVE A RECALL ON THIS EXPENSIVE GASKET FAILURE. *JB

LOW COOLANT LIGHT ON OUR 2000 IMPALA WAS COMING ON AND THE LOWER INTAKE WAS FOUND TO BE LEAKING - COST $600 TO REPAIR. RECEIVED A RECALL NOTICE ON OUR 2003 IMPALA FOR THIS CONDITION. REQUESTED REIMBURSEMENT FOR OUR 2000 IMPALA REPAIR AND WAS DENIED.*AK

INTAKE MANIFOLD GASKETS WENT COSTING OVER $600 DOLLARS TO REPLACE AT LOCAL CHEVY DEALERSHIP, ASSUMED THIS WAS JUST A SLIGHT PROBLEM BUT I SEE IT HAPPENING TO A LOT OF IMPALAS... I KNOW THERE'S BEEN A RECALL BUT NOT ON THE 3.4'S SOMETHING NEEDS TO BE DONE ABOUT THIS SINCE CHEVY KNOWS THERE IS A MAJOR PROBLEM HERE... *LA

INTERMITTENTLY WHILE DRIVING BETWEEN 30 AND 35 MPH ENGINE STALLED, FORCING THE CONSUMER TO PULL OVER. WAITED 10 TO 15 MINUTES TO RESTART THE VEHICLE. DEALER DIDN'T KNOW WHAT WAS WRONG WITH THE VEHICLE.*AK
