Four problems related to engine and engine cooling have been reported for the 2009 Chevrolet Malibu.
The contact owns a 2009 Chevrolet Malibu. While driving approximately 50 mph, the engine warning indicator illuminated with constant reduction in the engine power. The failure recurred whenever the vehicle was in operation. The vehicle was taken to an independent mechanic for diagnosis where they informed the contact that the crank shaft sensor would need to be replaced. The vehicle was not repaired. The manufacturer was not notified of the problem. The approximate failure mileage was 42,000.

Took car into shop over a year ago because bad odors were coming out of the cabin air supply. The Chevrolet shop cleaned out the a/c - took car back 8-9 months later, smelly odors coming from air vents in car. They cannot fix - these cars are not equipped with cabin air filters. . . In 2009 but - are now in 2012. I had bronchitis and near pneumonia for a year and a half. A month ago, I was told that I have asthma. These health issues are serious - I'm 64. I now need inhalers, etc. The car seems now to function okay with the inside a/c buttons but the fumes are there without these buttons. I'll again need heat in the winter and suspect the problem to return. Also, I don't always need a/c but have to drive with the windows up because of the horrid northern va traffic. There is no work around and I cannot afford to buy another car.
This problem is very intermittent and impossible to duplicate by gm service technicians. It is very intermittent to me as the driver too, and I have to date been unable to know what triggers this. It seems totally random. Intervals have been as little as one week and as long as two months. The event is car engine has near complete loss of power; engine timing pings heavily, engine power surges then complete loss of power. This is the most severe symptom. The car also encounters moderate pinging, loss of power that causes the car to be very difficult to drive. I have to pull over to the side of the street every time due to the unpredictability of engine power. The car has died on the interstate freeway and when I push on gas pedal, engine power gets weaker and engine pinging is extremely strong. Coasting to side of freeway is only safe thing to try.
