2014 Lexus gx 460

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! A door ajar warning that stays on when everything is closed is usually pointing toward a faulty door jamb switch, which is the little button that gets pressed when the door closes and tells the car everything is shut. Over time these switches can wear out, corrode, or get stuck in the open position. It could be on any of the doors including the rear hatch so it may take a little process of elimination to find the guilty party. Visit RepairPal.com to find a trusted shop in your area that can track it down quickly!
