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.

Electrical system going out only at night because headlights and inside lights are turning off for a few seconds only while driving at night this has happened multiple times since august and is becoming a safety concern while driving at night it's a safety concern because this has happened incoming traffic on roads and highways. The vehicle hasn't been inspected by dealership I tried calling to get an appointment but was told there is a fee and if something electrical a may have a cost per hour to inspect. No warning lights are turning on prior to headlights and inside lights going out. During the day no issues with vehicle. I've read a few online posts from other owners with same issue.

The brake lights fail with no warning. Bulb replacement used to work. Since ownership at +70,000 miles, I have had to replace one or both of the tail light sections as they melted. The lighting harness has been changed multiple times. In January 2024 Hyundai issued a warranty extension to 15years/200,000miles. There is no date on the letter. When I tried to get my car serviced there were charges for testing to ensure that this was the problem and it was difficult to find someone to service the car in a timely manner. The police continue to issue me tickets for no rear brake lights. The Dealer who finally serviced the car indicated that the Warranty was Void as the replacement parts were not Hyundai parts. Servicing the car was well after the original warranty was already over, so why would you worry about warranty claims for original parts. They claim that they cannot diagnosis the problem without original parts. Hyundai Corporate Customer Service was no help in this matter, but they did apologize for the problem. Can't drive a car without tail lights and paying 850 for the repair is one month of my disability check.

Right brake light assembly melting around lightbulb and right brake light not working due to the burn. I went to multiple used auto parts store to try and buy the right brake assembly and noted multiple cars from 2011-2014 had the same issue.

When head lights are in Auto mode occasionally all of the exterior and interior lights go out. Including dash lights. I cannot make it repeat at will so nothing ever gets done with it. There is no warning when it happens just complete darkness inside and out. Obviously I can’t see where I’m going when it happens they typically come back on after a few seconds. This has been happening for over 1 year. I don’t use the lights in auto anymore, it doesn’t happen when it’s not in auto.
