Hyundai Sonata taillight short issue with intermittent functionality requiring new housing unit and lights on Hyundai Sonata

Some Hyundai Sonata owners report experiencing tail light switch problems, including tail light housing melting, which can lead to improper functioning of the lights. This manufacturing issue may cause intermittent tail light failures, necessitating the replacement of both the housing unit and the lights. Additionally, some owners have reported failures with LED tail lights, with average repair costs reaching $1,350 around 76,950 miles. There have also been cases where the tail light wiring harness melts, resulting in overheating bulbs and further melting of the tail light housing, creating safety hazards such as headlights turning off when using a blinker at night. To mitigate these risks, it is advisable for owners to consider replacing the tail light housing unit with a high-quality, waterproof, and dustproof option to enhance visibility and safety while driving.
