First off, big Honda fan. Just got bad car. 2 months old took it in for "ting" in motor. Service found loose exhaust valve on #4 cyl, broken exhst valve spring on #3 cyl, Vtec system not working (dead solenoid), passngr side motor mount installed backwards. 17 days in shop, top half of motor was replaced (cylinder heads, valve train & solendiod), motor mount re-installed. Lot of issues for new car. Told Honda we wanted "out", corporate said no, it's fixed. It goes in this week for spazdic rear wiper (rear swipes randomly when front wiper on and rear wiper OFF). Had lots of Honda's, these issues aren't typical. This may be the best running Fit on the road right now but will trade in ASAP.
Mileage is great. Bought it as a commuter & travel a lot between LA and Phoenix. HUGE cargo room (with rear seat down), was able to load a 47 inch LCD TV with all packaging & it layed flat in the back. That may not sound big but those TV's have a LOT of Styrofoam around them. :)
QC?, QA? Based on driving before & after, the motor issues were there since day 1. This was the only Fit we test drove.
