Nothing.
I love this car. It's my favorite car ever - better then the Jeep I had previously.
The only thing I don't like about it is it's kind of rough on the road, but that's to be expected from a small car.
I haven't had to change anything yet - except general things.
We had to change some "general" things on our Civic too. Like the ENGINE at 90,000 miles. Hope you have better luck!!
