Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The Malibu engine smelled hot and fluid was leaking onto the garage floor. A mechanic discovered that coolant is leaking onto the top of the transmission from the intake manifold gasket. We have added fluid a couple of times. The gasket will have to be replaced. I believe that GM should replace this since it is a commonly known problem on this car.”
NHTSA complaint #10110734, filed 2005-02, 57,428 miles“Antifreeze used in our 2000 Malibu has been found to frequently cause deterioration and failure of the intake manifold gasket. There hve been many cases sited on the internet with names and specifics and chevy/gmc refuses to admit it is the antifreeze. They told me last night it has to do with the plant where the car was made.”
NHTSA complaint #10057132, filed 2004-02, 122,000 miles“Engine overheating, also the turn signals are erratic, when they do not work I have to turn my emergency flashers on, then off, and the turn signals work then. As far as the overheating goes, I took it in for repair (over $350.00) they said they found water in the oil and replaced head gasket. It still is not fixed. This car has 45,000 miles.”
NHTSA complaint #10032584, filed 2003-08, 44,000 miles“Dex-cool coolant leaked into engine of my 2000 chevy Malibu. This is an ongoing problem for many GM owners, and it is well known by everyone expect GM. Both the dealer and Chevrolet said there is nothing they can do, that I must pay to have it fixed, about $1500.00. Chevy must address and fix this problem .”
NHTSA complaint #10139618, filed 2005-10, 38,000 miles“I have a 2000 chevy Malibu with 38000 miles. The intake manifold gasket is leaking. I called the dealership to see if there is a recall. I was told there have been many gasket failures on the Malibu but there is no recall. Repair cost is estimated at $645.00 by the dealer. I am now unable to afford the repair or safely drive the car for fear of damage to the engine. The car is now in storage.”
