Suspension: frontReported May 27, 2009 · 36,538 vehicles affected
What is wrong
Kia motors corporation (kmc) is recalling 36,538 model year 2001-2004 optima vehicles originally sold in or currently registered in the states of connecticut, delaware, illinois, indiana, iowa, maine, maryland, massachusetts, michigan, minnesota, missouri, new hampshire, new jersey, new york, ohio, pennsylvania, rhode island, vermont, west virginia, wisconsin, and the district of columbia. Road salt applied in these states during the winter months may result in progressive, internal corrosion of the front subframe.

Corrosion of the front subframe could lead to separation, possibly resulting in a vehicle crash.
Remedy
Kmc will notify owners and dealers will repair the vehicles free of charge. The safety recall began on june 15, 2009. Owners may contact kia's consumer assistance center at 1‑800‑333‑4542.

Filed Feb 3, 2025 · Engine, Steering · MO

While driving on the roadway, I was almost to a four way intersection, as i was going to get into the left turn lane, I turned the steering wheel slightly to the left as the steering wheel turned but the car almost did little adjusting to turn into the left turn lane. As this occurred you could here a noise underneath the vehicle . As I wasn't sure exactly what had happened, I attempted to limp the vehicle down the road to a friend's. As I did the steering got worse and as I could nearly stear the vehicle something was in the road which because of the steering I couldn't avoid it as it was late at night and raining and I ran over something that gave me a flat on the passenger side front tire . I got to my friends drive a few feet away and almost didn't get it pulled in because of the steering. As I took a look at my car, I noticed that two bolts on the driver side on the rack and pinion were almost about to fall out, two ball joints were bent and one nut was completely missing from the lower ball joint, as well as the sway bar was out of place and If I would have been driving down the highway, I do belive I would have wrecked.

Drivers side door will not unlock with key or inside door look switch. This is a real safety hazzard.

Filed Dec 27, 2017 · 24,000 miles · KY

At 24,000 miles my vehicle started locking doors when temperatures reach 32 degrees or lower. Vehicle outside on city street or driveway. When temperatures get to 32 degrees, doors lock and do not unlock to allow access. If you are inside of car it locks you inside of car, as well as out of car. Locks unlock then lock instantly even when using key, not key fob to unlock car~ no access to enter vehicle until above 32 degrees. In case of emergency...you have no vehicle. This has happened every year when temperature gets below 32 degrees. I have reported this problem in past.recall and fix it please!!!

Drivers side door will not open if locked when closed. Mechanism works fine to lock and unlock when open, however. A part in the lock assembly appears to be rotating too far and getting stuck. As a result, the door cannot be opened if locked when the door is closed or the driver will have to climb out of the passengers side door or through the window.

My main issue is the door lock on the drivers side. I can not open my drivers side door from inside or outside the vehicle. This is a major issue and the problem has been all over the internet for years. Everyone that I know that has a 2003 and 2004 kia optima has the same problem. I bet every vehicle kia sold for these years has this problem. My other issue is I am unable to fill my fuel tank as I normally could do. I have to trickle the fuel in the tank because if I pump it too fast the pump will cut off. I've even had the fuel spill out of the tank before the tank was even full (it was at about 3/4 full). Please demand that kia recall these problems. I can't believe it's taking this long for this recall to be issued. I just found out about this form and that is why I have taken so long to process this form. Thanks and I hope that you can help asap. [xxx] ps. As of today my vehicle has approximately 53,000 miles. I've driven it in one winter so far (last winter) and it started having the door lock problem at around 33,000. The fuel issue started around 2 years ago. Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
