Known issues on the 2004 Optima. One recall is on federal record for this model year, and it concerns the front suspension: corrosion of the front subframe could lead to separation, possibly resulting in a vehicle crash. Kia recalled 36,538 Optima vehicles from the 2001-2004 model years under that campaign. Owners have filed 306 complaints for the year and Kia has issued 14 technical service bulletins.

Whether you are checking the front subframe for corrosion, chasing a fault on the 2.7L V6, or working through a scheduled service, it keeps you on Kia's own procedure and the correct figure for your 2004 Optima.
