I have a 2001 kia optima with only 62,000 miles. car was pulling to right thought i needed an alignment. when car went up on lift mechanics were surprised that car was still drivable and that we were safe. frame/subframe under pass. seat was rusted through, about the size of softball. makes me sick to think that i had my medically invalid daughter in this car. when doing research on car i see a lot of rust issues in frame, subframe or rocker arm area. there must be some thing done about this problem. seems like there is a one problem (rust in frame area) but there are different outcomes in the frame /tire/under engine area. still waiting to hear from dealer regarding repair cost-- i will fight not to pay. this is a safety issue there should be recalls. *tr
