NHTSA Complaint #11624381 — 2014 HYUNDAI SONATA

The turn signal stem assembly randomly begins failing after several years (approx 5 years). Issues will be noticed while driving in the dark. When turn signal is applied in both directions, occasionally headlights will turn off or flash causing interior lighting to change to brighter daylight settings at the same time. This can be disorienting for the driver as well as others on the road. To remedy the incorrect lighting situation, the driver needs to jiggle the turn signal stem assembly and normal lighting will resume. At subsequent turns, the entire situation repeats itself. Other drivers may believe they are being alerted to something or potentially angered, causing misunderstandings or altercations on the road. My original turn signal stem assembly was replaced after about 5 years due to this series of events. Now, after approximately 5 more years, the exact same symptoms have begun again with the authentic Hyundai OEM replacement parts.
