Nothing.
The only conmplaint that I have had is the gas mileage is less than expected, but still really good. This car was larger than a sentra or corrola and has better perfromance. I still get about 33 mpg average, but it boats up to 38 and we have never gotten that on all highway driving.
Do you know what "no maintenance" means?
See how far it goes if you keep up the no maintenance thing.
