Only problem we have had with our Civic is uneven rear tire wear. After taking it into the local Honda dealership they were able to determine that there was a problem with the rear suspension that caused the tire wear. They replaced all of my tires (over $600) under warranty and stopped the problem. Later, they were able to correct the suspension problem with a replacement part and we have had no further problems. We average in the low to mid 30's on daily mpg and have gotten as high as 44 mpg on the highway. Fantastic car. We have driven Hondas since 1987 and have never had our vehicles in the shop for anything other then scheduled maintenance.
Love the digital dash display and don't really feel like we are in a small car because of the room inside.
A telescoping steering wheel would be nice. Seems like to get plenty of leg room behind the wheel, I have to sit quite a way back from the steering wheel, resulting in having to stretch my arms out to steer. Can be uncomfortable after awhile.
