Kia Sedona brake lights not turning off, causing battery drain on Kia Sedona

Some Kia Sedona owners report experiencing issues with brake lights that remain on, leading to battery drain. A common cause of this problem is a faulty brake light switch, which can wear out over time and cause the lights to stay illuminated even when the vehicle is off. Additionally, some owners have noted that if the battery drains while driving, it may be due to a malfunctioning alternator that fails to generate sufficient voltage for charging. Other potential culprits include blown fuses or a malfunctioning brake light switch, both of which can also keep the brake lights on. Furthermore, a broken brake light switch may result in additional complications, such as the inability to deactivate cruise control, difficulties in shifting out of Park, and issues with the start-stop button functionality. To resolve these concerns, it is recommended that owners inspect and possibly replace the brake light switch, check for blown fuses, and ensure the alternator is operating correctly to prevent ongoing battery drain.
