Driver's passage is very uncomfortable for anyone over 6 feet. Others have commented on head rests being poorly designed - I agree 100%. Highway noise is quite annoying, needs more insulation. Pickup is OK at best, but what do you expect for a 4 cylinder. My biggest complaint is that I have had to had the brakes worked on twice with less than 30,000 miles. I have minivans that are far heavier that don't need brakes until 50,000 miles or more, and I drive them the same way. I also had to have the differential serviced. The service people basically said you can't leave the car out in the rain because the brakes will collect water, which led to my problem.
Window control automatically goes all the way up or all the way down - no other car I have driven does this. I always wondered why they don't. I also like the ipod jack and fold-down seats, although they don't really fold flat.
Redesign the brakes and the headrest, add a bit more leg room for the driver.
