automatic headlight

Hi, I'm one of the auto experts on RepairPal's Car Genius team! Great question! On your 2020 Kia Forte having both the daytime running light and the automatic headlight function stop working at the same time is actually a helpful clue, as it suggests a shared component may be the culprit rather than two separate failures. The most likely suspects would be a blown fuse, a faulty ambient light sensor that controls the automatic headlight feature, or a failing light control module. It's worth checking the fuse box first as a blown fuse is the simplest and least expensive possibility. That said, since this is a 2020 vehicle it may still be under Kia's warranty, so we'd recommend checking that before spending any money on repairs. If it is out of warranty a qualified shop can quickly diagnose whether this is a simple fuse fix or something more involved with the lighting control system.
