The moonroof malfunctions and can be stuck in the open position. The drain plug for the moonroof can easily get clogged causing water to back up into the overhead structure. This causes water to fall onto the driver and passengers. The water flows from the overhead area, the side pillars and onto the floorboards. The electrical components are then compromised and the motor that controls the moonroof stops working. In my situation my moonroof was stuck in the open position for several days. I live in Florida where it rains alot. It is not safe to drive with an open moon roof during a severe thunderstorm. In doing my research this seems to be a very common problem with Ford moonroofs. I’ve had to have it fixed twice now. Luckily the first time it was stuck in the open position but water continued to pour into the interior of my vehicle while I was driving. This caused me to be distracted as I was driving. I had it repaired both times at a Ford dealership
