 I bought my Forte EX 2011 new.I am disappointed with the gas mileage I've obtained which for an entire tank remains averages between 20-25 mpg with about 60% city and 40% hwy driving.Yet the worst features are the audio unit and the customer service (both corporate and local).My audio unit will randomly start whistling loudly, will turn itself off, bluetooth turns on and makes settings changes without prompting, the CD device fails, and all of these issue repeated after KIA replaced my audio unit with a brand new one.These glitches occur a few times a week while I'm driving.I've had complaints with KIA that have not been resolved for the past 4 months.I feel ignored by KIA.
