This is a major issue thousands are having with this model 2014 Sonata. When using the blinker, it causes the headlights to completely shut off while driving. Soon as the blinker turns off it kills the headlights. Extremely dangerous and Hyundai seems to be ignoring this issue and pretending they're not hearing of it often. I've had to pull over many times until the lights come back on. Seems to be an issue in the steering column. Cruise control also decides when it wants to work. Sometimes on startup it works, sometimes it doesn�t. I believe it has to do when the car is started. Something odd electrically with these cars. But the blinker/headlight issue is causing wrecks. This is wildly dangerous.
