Why does your interior lights come on while driving and sum time the door says is ajar?

If your interior lights come on while driving and the door ajar warning appears, it typically indicates that a door is not fully closed or that a door switch is malfunctioning. Vibrations from driving may cause a partially closed door to shift enough to trigger the sensor. Additionally, dirt or corrosion on the door latch or switch can lead to false alerts. It's advisable to check all door latches and switches to ensure they are functioning properly.
