What owners are reporting 2 most recent
My 2012 Kia optima headlamps are extremely dim, even though I’ve replaced the lightbulbs with the highest possible lumens, multiple times, the headlamp assembly continues to dim. This requires that I ride with my high-beams on to drive at night. The lights have been dimming for more than 20,000 miles, but they are almost useless at this point.

A quarter of owners report trouble before 70,000; a quarter make it past 102,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.

The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
