How many miles will a 2003 Optima last?
The 105 mileages owners gave run from 31 to 180,000 miles. A quarter are at or under 58,671 miles, half at or under 84,200, three quarters at or under 109,000 and nine in ten at or under 136,000; 31 (30%) came after 100,000 miles, 7 (7%) after 150,000 and none after 200,000.
These mileages say when owners reported a problem, not when a 2003 Optima wears out. NHTSA's file holds only vehicles whose owners complained; one that ran without a problem never appears in it, so it gives no lifespan and no cutoff, and how a vehicle was maintained matters more than any one odometer reading.

Is the 2003 Optima a good year?
Complaint counts cannot say whether the 2003 is a good or a bad Optima: they rise with how many were sold and how long they have been on the road. They show how the 2003 compares with the other model years in NHTSA's file.
With 141 complaints, the 2003 ranks 17th of the 20 Kia Optima model years from 2001 to 2020 with 10 or more complaints, counting from the most. The most: the 2013 (1,444). The fewest: the 2010 (75).
Recent model years have had less time to collect complaints, so their counts are still growing. No year is ranked by mileage here, because a year's median mileage mostly follows its age.

2003 Kia Optima recalls
NHTSA's recall files of November 11, 2026 list 2 recall campaigns that name the 2003 Kia Optima. A campaign covers a production range, not every vehicle of the model year: check the VIN with NHTSA's free recall lookup.
What these figures can and cannot tell you
- Complaints are owners’ reports to NHTSA. NHTSA publishes them without verifying them: a complaint is an allegation, not a defect finding.
- The mileage is what the owner wrote on the complaint; NHTSA does not check it against the odometer.
- The make, model and model year are the ones on the complaint. NHTSA records them as filed, so a few complaints sit under a model year the name was not sold in.
- They are not a lifespan study. The file holds only vehicles whose owners reported a problem, so these figures do not say how long a typical 2003 Optima lasts.
- A complaint count rises with how many vehicles were sold and how long they have been on the road, so it is not a rating of the 2003 Optima.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 36 of the 141 complaints on the 2003 Kia Optima give no usable mileage (blank, zero, a filler such as 999999, or over 500,000) and are left out of every mileage figure.
- NHTSA names counted: OPTIMA, OPTIMA HYBRID and OPTIMA PHEV. NHTSA files some vehicles under several names (a series name and a trim name, for example); this page counts only these.
- Recall-file names matched: OPTIMA, OPTIMA HYBRID and OPTIMA PHEV.
