The rear end of the car makes a weird whop whop sound when you are driving it has done this since I have bought the car and has gotten worse. When I complained to charper they told me all the Kia Rios do this. I fear that a rear wheel is going to eventually come of or blow something. Cant even put windows down when driving it sounds like a helicopter is landing on the roof it is that bad. Hurts your eardrums. Happens no matter what driving condition.

4 tires with only 17,000 miles on them, have rubber dry rot cracks on sidewalls and always need all 4 tires air adjusted back up over short time, and always look dingy dirty from road dirt in cracks on sidewall. Safety hazard ? kumho solus KH25 dot yoah ypl8 (5111 ) 185\65R15 all 4 tires same dot. Car kept garaged and hardly driven since purchased new. Tires should not be doing this. I contacted company but not replying to phone calls and I sent emails " I noticed same brand being replaced by company with bigger size same problem recall " updated 12/01/15
