Kia Sedona Power Sliding Door Switches May Get Stuck in The Open Position
Kia Sedona Problem
Average Mileage: 84,600 mi (60,000 mi - 138,000 mi)
I had a heck of a time with those darn doors! The rear power doors both kept opening while driving. I turned the power off and locked doors, still they kept opening and bell dinging doors open! Eventually, took to dealer and installed 2 new door latches.

Passenger sliding door lock will not lock or unlock. I have to keep the door switch in the lock position in order to lock the vehicle. I can press the door open button from inside the van, or press the door open button from the key chain. If the door is unlocked, I cannot lock it. If it is locked, I cannon unlock it other than sliding the manual switch on the door itself.
