Problem overview

Some Subaru Legacy owners report experiencing issues with brake lights being stuck on, often due to a faulty brake light switch. This component is vital for controlling the brake lights, and its failure can result in the lights remaining illuminated, which poses a safety risk. Additionally, if replacing the brake light switch does not resolve the issue, some owners find it necessary to inspect the wiring harness connecting the brake switch to the bulbs for potential problems.
