Since purchasing my car in August 2013, I have had to make three fairly costly repairs. Each time the mechanic told me this was a "known problem" for Chevrolet. The first was the intake valve. I hadn't experienced problems but took the car in for what I thought was a squealing belt. The squealing turned out to be the water pump. Since that was secondary in importance to the intake valve, I had that replaced first. Followed by the water pump a couple of months later. Then about a month ago, I was out of town and my car suddenly would not shift into park or reverse. It was a worn and stretched shifter cable. However GM says my car is not part of the recall.

Fueled up and the gas light and check engine light came on. Gas gauge went up and down and now stays on. Does not recognize fuel is in the car and always says low fuel even after fueling up. Both check engine and gas light are steady on.

My 2.2 liter 4 cylinder Chevy engine in my 2007 Chevy Malibu started to misfire and the check engine light came on when I started my car in the morning. I brought it to a Chevrolet dealer in lodi California and after testing it they said it had a burnt valve in the #3 cylinder. I brought it to two other independent repair shops and they both said that there is a factory flaw in the cylinder heads that cause the valve seats to fail under normal use and cause the engine to misfire.

2007 Chevrolet Malibu. Consumer writes in regards to driver door lock malfunction caused by poor wire connection and consumer seeks reimbursement for repairs. The consumer stated while driving, the tire traction light illuminated and he was unable to turn it off, and then the check engine light illuminated. He was also unable to use the speed control setting, during that time. When he arrived home, he was unable to get out of the vehicle, because the driver door auto lock wouldn't operate properly. Two days later, when he put the vehicle into drive, the driver side door didn't lock automatically, but all the other locks worked properly. The dealer informed the consumer the harness came loose and it caused the wiring under the driver's seat to chaff and expose the wiring which then touched each other and caused the malfunction. He further advised that, as part of the repair, the harness and wiring were moved over from its original location so that the problem would never occur again.

Last week my car started creeping when I hit the gas. My car sounds like a boat. The car sounds like its not getting gas or choking. When it starts picking up speed it sounds like its dropping into the gears. I took it to the shop and they are telling me that there is a problem with the catalytic converter and it needs to be replaced. That has been replaced now they are telling me there is a problem with the timing chain and water pump. Now, I noticed that these are all things that are covered under Chevy warranty but the issues shows up after the warranty has ended. Chevy needs to extend the warranty on these parts because its a common issue.
