Kia Optima is the worst car on the road. Kept having problem, after problem, after problem with the engine. Took to be repaired numerous times and tried several times to have Kia honor their warranty and they would not. Was never given an owner's manual and asked several times for one. When took it to be repaired, all they said was "this isn't covered because you didn't follow the your owner's manual instructions." Kinda hard to do so when was not given one in the first place! It is nothing but a piece of crap and the worst car ever made. Kia's are nothing but "throw away cars." Will NEVER own another Kia!
