Same issue with a 2017 Everest Trend, again with extremely heavy rain. This is the 2nd time this has happened with an Everest I have owned. Makes me wonder if there is a sensor that opens the windows if the vehicle thinks it’s submerged? Anyway, four+ hours of torrential rain overnight, car pretty much ruined with all the door electronics soaked, speakers dripping water, seats soaked, and 20mm of water across the carpets. Calling insurance company and Ford today.
