Kia Sorento battery drains within 8 hours with interior lights malfunctioning on Kia Sorento

Some Kia Sorento owners report experiencing rapid battery drainage due to malfunctioning interior lights, which are often caused by a parasitic power draw. This issue can manifest when the interior lights remain on longer than the typical 30-40 seconds after closing the doors, leading to significant battery drain within just 8 hours. Owners are advised to test for a parasitic power draw using a multimeter and to verify the battery current draw when the vehicle is off. Additionally, some owners find it helpful to rig door switches to prevent the interior lights from activating unnecessarily and to unplug the hood light to eliminate extra sources of power draw. Promptly addressing this issue is crucial to prevent further battery problems and ensure reliable vehicle starting.
