The rear drivers side sliding door no longer functions. The issue began when the door would intermittently make a buzzing sound but would not open or close. Shortly after, the door continued the first issue but also began pulsating when it actually would open. Around the same time these issues began, the door started opening by itself while driving. Though i have not had any accidents yet, several near misses have occurred due to the confusion and stress that this generates. The opening while driving issue occurs most often when on the highway. The primary passengers in the rear are children so there is heightened risk based on their very appropriate age based reaction of panic. The door is also no longer opening electronically from the key fob nor from the front seat buttons.
