 My story is not as bad as others, but here are the problems:  unstable in winds, spark plugs a pain to replace, -cannot drive on any amount of snow -drink holders break easily -one passenger window stuck for a year -fuel pump squeals -check engine light constantly on -exhaust rattles -underpowered -extended warranty was a Ponzi scheme fraud -replaced battery only to cause more electrical problems -air conditioning weakens in a year -KIA dealership service is a joke at best -paid off car only to have it become un-driveable soon after -cannot fit three children's car seats comfortably -would not sell on used market -mileage drops off rapidly -alarm so difficult to turn off it goes unused
