 We purchased our Kia new Feb. 2006 when it had about 18 miles on it.  In less then 6 months the check engine light came on.  Not a big fan of dealerships but assuming things are under warranty we take it to the dealership in the town we live in.  We are told it's not covered anymore by about 800 miles ago (CO2 sensor).  We fixed it ourselves. Light still randomly comes on and goes off.  We blow headlamps what had been about 3-6 months apart but now as soon as 10 days.  My dash light has been randomly going off for about a year and now my dome light randomly goes on.  Our dome light stopped working correctly 2 years ago.  Very uncomfortable on long trips especially for tall men. Just a gag car!
