New Car Assessment Program

The 2004KIAOPTIMA carries 306 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 14 crashes, 4 fires, 10 injuries, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.

Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2004 OPTIMA is latches/locks/linkages with 73 filings, followed by electrical system (41) and structure:body (28). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 1 active recall campaign, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.

NHTSA currently has 38 investigation files overlapping the 2004 OPTIMA, and 1 remain open. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

Had some noise coming from the front of the car, had my mechanic look at it, he said we needed a control arm. When he took off the cover to replace the control arm, he found the sub frame had rotten and was cracking. As I looked online, I saw that KIA had a recall for this issue. When I contacted KIA, their response was "as my car is not under warranty, they are not required to repair the car" The car in question has 70, 558 miles on it. We are the 2nd owner.

Door lock/unlock mechanism has failed. Unable to unlock and open door from outside or inside. This defect causes the door to stay locked and unable to open. This can trap people inside of the car if they are unable to crawl out a window or exit from another door. There are many reports of this on Kia forums and general Google search. There was no warning that this part was wearing out until it became impossible to open the door.

DRIVER'S DOOR LOCKING SYSTEM WILL NOT UNLOCK, ALL OTHERS DO. THE DOOR LOCKS ITSELF IMMEDIATELY AS YOU TRY TO UNLOCK EITHER WITH THE KEY (OUTSIDE) OR PRESSING THE CENTRAL LOCK BUTTON (WHEN INSIDE). THIS WOULD BE A SERIOUS PROBLEM IF THE CAR WAS INVOLVED IN AN ACCIDENT AND/OR FIRE WAS AN ISSUE. RIGHT NOW IT IS INCONVENIENT TO CLIMB OVER THE CENTER CONSOLE. I SEE THIS IS NOT THE FIRST COMPLAINT ON THIS SUBJECT AND THE PROBLEM SEEMS ENDEMIC TO THIS CAR. THE PROBLEM STARTED INTERMITTENTLY FROM SEPTEMBER 2016 AND NOW IS PERMANENT AS OF NOVEMBER 30.
