I have the kia Optima sx with the technology package that comes equipped with the auto-leveling and auto-bending led headlamps. I believe that the auto-leveling function is working incorrectly. When weight is added to the car (more passengers) the beam pattern auto adjusts itself to point even lower instead of higher. This causes an adverse effect. Think of it this way, the beam has a default setting to where it points to when there is no weight added to the car. When two passengers sit in the car, the beam should not point lower, instead it should auto-level itself to a higher position to accommodate for the fact that the vehicle is now lower when weight is added to the vehicle. I also believe that the headlights by default are pointed a bit low, I went to the dealership (concord kia in concord, CA) to have them re-adjusted. Alas, no better result was achieved due to the fact that they are auto-leveling. Often when driving in the car with my fiance (a combined weight of about 600 lbs distributed to the front seats), the led low-beams appear to reach a max distance of 40 ft on level land, and around 70 ft. Going up a hill. When one is going downhill, the projected led light reaches a distance of around 25 ft. I understand that the 2017-2020 kia Optima sx models equipped with the auto-leveling and auto-bending lights have received a fantastic rating. I am sure when the lights are working at Optimal conditions (1 person in the car who may weigh under 200 lbs) the lighting can be great. However, I encourage the nhsta to re-conduct a thorough test under the following conditions: seat two people in the front who weigh at least 200 lbs. First seat one person, notice the beam pattern against a wall about 50 ft. Away, then seat another person in the vehicle and notice how the beam pattern is lowered. I also encourage the testers to drive the around a bit.
