Pay very special attention to the plastic coated steel wire that is
part of power sliding door mechanism.
You can find this wire in the groove/track under the rear windows.
The plastic coating of this wire on my van dried up and cracked, exposing the steel wire. When this happens, the door will be hard to open.
When the steel is completely exposed, eventually the cable can snap. It happened to me and my doors (yes, both sliding doors) are only in manual mode now. I was told that it would cost $2000/door to fix.
The front doors have welding issues. When they are opened and closed, they make a LOUD "snapping" noise.
This model came with runflat tires. They are expensive to replace.
Power Sliding Side Doors...
When they were working...
Either rework the power sliding door mechanism so that no coated steel wires are used or warranty the power door mechanism (includes everything that has anything to do with the opening and closing of the side doors) for life.
Ditch runflat tires!!!!
