Your rear hatch lid sensor may think the hatch isnt closed thereby allowing the trunk light to remain on. Go to your trunk. Fold the parcel shelf halfway and reclose the hatch. Is the trunk light on? If so, locate and remove the trunk light bulb by pulling it downward. Its bullet connector ends are retained by contact pressure.

Happy trails!
