The brakes and rotors are constantly requiring replacement.
The 2003 Chevrolet Malibu center console is loose. It was tightened and loosens up again. It's just not very good quality workmanship.
The security system is a pain. If you don't have the shifter in a specific spot, it won't let you remove the key. If you're too rough with it, the security system shuts down the entire car, and you need a tow back to the dealership.
It supposedly has a security system, but Chevy wants over $200 for the keyfob since I bought the car used (2 years old). $200 includes the cost to scan the system for the right security numbers to unlock the doors. I've just used the key, the repairs are over $1000 already.
Very rough suspension.
No amount of alignments seems to help this car. It's just not aligned properly (the new ones are like this too).
Do not buy this car.
My mother owns a 2003 and she has twice been unable to start the car due to the security system. Has had to have the car towed and part replaced twice. Very expensive. According to dealer part could last a year to 5 years. Unbelievable!!! Especially since the car only has 15,000 miles on it. I own a 2001 Honda, never had a problem with the security system, Part is defective not that they will admit that. She has owned Chevy cars for 50 years but will never buy another because of this.
