Power windows stick on occasion, but just hit the switch again and it's fine.
Sunroof rumbled when opening, but just needed greasing.
The temperature gauge always ran a little higher right after idling, but always went back down and never got hot.
The driver seat bolster on the outside of the seat was "dislocated" to the left and on the side of the seat.
The rear speaker sounded scratchy sometimes, but I like my bass.
I only had the car 2 weeks before I totaled it. I went off of a gravel road and hit a tree doing 45 mph which threw the car on the driver side. The seatbelts locked immediately and the airbags deployed just as they were suppose to. The car is totaled and I sure am glad that I didn't have a passenger because I had hit on the passenger side. I honestly believe the passenger may have been seriously injured, although I did hit the tree at a "different" angle. People aren't quite sure how I hit the tree, so the car is actually completely totaled; the passenger front floorboard, including the rear passenger floorboard are completely bent. I had bent the frame from the front to the back wheels. I felt very safe in it though. My car had basically everything in it so mine was very enjoyable while it lasted. I am actually looking for another Malibu!
Stay away from the 2004-2007 Malibu. There are some big issues with the electronic power steering.
