The anti-freeze holding tank keeps getting an oil residue in it and the anti-freeze keeps disappearing into the engine and has to keep being refilled. After speaking with a mechanic it is possible that the intake manifold gasket is failing. The A/C switch also turns off on its own. Rotors and brakes have been replaced three times.

Chevrolet Malibu intake manifold gaskets" begins to leak anywhere around 80,000 miles of driving. This causes the car to leak coolant, to overheat, and motor will lock, burn out. This car was not even 5 years old, and I have spoken to other Malibu owners who had this work done of their cars costing $500 to $700 I felt as though the manufacturer needed to improve this gasket and replace the cars that already had this defective part.

Catalytic converter went out while traveling 500 miles from home. Mileage was only 60000 miles. Was under warranty but part was on nationwide back order. Chevrolet customer service would not authorize rental or towing. We were stuck for two extra days while someone took coverter off and drove home without it. Then I was informed by customer service that I had voided warranty. Dealership was able to get coverter replaced under warranty only after a huge fit was thrown on my behalf. Second, gas cap seal is bad; after fill up sometimes have to restart car because empty light comes on. Third, at 80000 miles the intake air gasket had to be replaced. Cost of $1200. Fourth, while trying to install after market cd player discovered that you have to buy $100 wire harness and new front speaker in order for stereo to work, the way Chevy made it to be.
