1 Turn Signal problem

Failure Date: 06/23/2020

2017 kia Sorento, awd, mileage ~30k. When the headlights are set to "auto", they will randomly turn off, usually when I activate a turn signal. It happens at all speeds, on all types of road, most often when I'm turning. I've had several 'close calls' at night. Obviously, if the lights turn off unexpectedly, not only can I not see my path forward, but others can't see me either. This is serious issue, well known to kia and should be subject to a recall before someone dies or is seriously injured. It has happened numerous times, most recently on the date shown below.

2 Turn Signal problem

Failure Date: 10/12/2019

When the headlights are in the auto setting, they will randomly turn off while driving. I most often notice this at night, but I can see it happens at times during the day if the lights are on because I notice the dashboard indicators change. This sometimes occurs after using the turn signal, but that's not always the precursor. It happens when going 65 mph on a highway, going 45 mph on exit ramps, on 25 mph on local streets. I reported the issue to kia customer service, and they said I had to take to a dealer. I took it to a dealer in October 2018. The technician drove it 50 miles round trip to and from his home, but could not reproduce the issue. The issue continued intermittently and I took it to a different dealer in September 2019. They diagnosed the problem as a bad electronic control unit and ordered the part. I returned to the dealer on October 12, 2019, to have the part installed. While driving later that night, the headlights turned off while I was going 65 mph on interstate 270. I tried to quickly jiggle the lever, and then the lights turned back on. Many others have reported this same issue. It's obviously dangerous, and kia should figure out the problem and issue a recall.
