The 2011 Hyundai Sonata has a known issue with tail light sockets melting or failing, causing intermittent brake light problems. This article will guide you through diagnosing the issue and replacing the tail light socket.

Common Tail Light Socket Issues

The most frequent problems with 2011 Hyundai Sonata tail light sockets include:

These issues often result in flickering tail lights or complete failure of the brake lights, which can be a serious safety concern.

Diagnosing the Problem

To determine if your tail light socket needs replacement:
