Why does my warning light on my 2004 kia sorento keeps telling me the door is ajar when it isn't?

The warning light indicating that a door is ajar on your 2004 Kia Sorento may be triggered by a faulty door switch or sensor, which can become worn or misaligned over time. Moisture or dirt in the switch can also cause it to malfunction. Additionally, if any of the doors are not fully closing or if there’s an issue with the wiring, it could lead to the warning light being activated erroneously. It's best to have the vehicle inspected by a mechanic to diagnose and resolve the issue.
