You will love the XFire.
Common complaints on the non-SRT models are non-working seat heater elements, fogged head lamp covers, rear hatch rattle (easyily adjustable), throttle lag (drive-by-wire - easily cured - if it bugs you buy a "Sprint Booster").
Think that just about sums up what seems to be the common ailments.
Overall the best, most fun car I have ever owned. I would buy another one in a second.
