So far, only the radio. It went out about 2 months after I bought it (1/04). The dealer replaced it under warranty (it's a pretty cheap one anyway). No other problems so far.
Minor issues with design: the steering wheel could come back just a bit for drivers of average height (I'm 5 ft. 9 in. tall). Its kind of a stretch on a trip with my hands on top of the steering wheel or at 10 and 2. Moving the seat far enough forward to accommodate my arms bunches up my feet at the pedals. It was designed for taller people.
The button for the air conditioning is too close to the blower motor. I constantly turn on the a/c by mistake.
The headrests on the back seat are annoying (and dangerous) blind spots for backing up and viewing traffic to the rear. I took them out (I rarely ever have passengers in the back seat. They're easy to put back in if I do).
So far, I'm very happy with it. Acceleration and power are awesome for 4 cylinder with an automatic. I take trips to Northwestern PA, and it handles the mountain climbing flawlessly with no strain (I don't have to downshift) It handles well and rides like a larger luxury car.
It has wide, comfortable seats which are great for trips. I'll take it over Honda Civic or Toyota Corolla any day!
I love it, but can't say for sure whether I would buy another. We'll see how it does a few years down the road when it has 80K miles plus on it before I make that decision.
The paint seems to be OK so far. No defects that I can see (the color is teal blue). It has a few minor scratches under the doors, but I would expect that with the harsh winters we have in the DC area. I keep it waxed and pray a lot.
