I bought a 2009 optima. I am having problem with breaking system and a few other problems...one dealer said no problem...purchase dealter (distance from my house) found several problems (patched up part of defrost strips on rear window and reprogrammed trany module) and corrected them, but still problems....especially uphill in snow...have to turn esc off and burning smell pressuring car to get up hill...there were a few other problems besides this
