| Description of the problem | I have 2011 kia optima sx with hid headlights and they have been dim for a long time. They became noticeably dim in 2015 and have ever since been dim and have had a noticeable change in the light pattern. This is not caused by foggy or yellowing plastic as the headlights have been protected by a clear plastic protective "sticker bra" ever since the care was purchased new in july 2011. The headlights are experience the same issue as other owners of the car, deterioration of the internal reflector for the hid headlight. As a result the light pattern becomes altered or dim. It is dangerous to drive at night with this car. The headlight have been replaced with no improvement in the lighting output or pattern. This is similar consistent with many owners of the same models. Kia has issued a warranty extension but the dealer needs to provide a video that shows flaking of the reflector between the space where the bulb is and the clear lens cap. This is not the reflector behind the bulb that would affect the light pattern. Dealers do not look at the light pattern as it is not part of the diagnostic steps. They only look for flaking of the reflector between the space where the bulb is and the clear lens cap which would seem to be more cosmetic then functional. |
