A vehicle door system includes doors with a door module attached to a hinge module, which is attached to the vehicle body. The door module includes a latch mechanism configured to engage a striker pin of the vehicle body, with a pawl that pivots to accommodate a misalignment with the striker pin during a door closing operation, with the latch mechanism shifting following engagement with the striker pin. A door check mechanism includes a permanent magnet and a steel plate. Activation of the permanent magnet shifts the steel plate from a closed position to an open position permitting the hinge module to move from a locked position. An interface between doors includes a primary and secondary seal each having a constant cross section, with filler pieces disposed between the door and the secondary seal along a portion of the interface.

A vehicle includes a vehicle body including a front pillar and a rear pillar spaced along a vehicle-longitudinal axis. The front pillar and the rear pillar define a door opening therebetween. A first track is supported by the front pillar and a second track is supported by the rear pillar. A bar extends from the first track to the second track. The bar is moveable relative to the first track and the second track from a lowered position to a raised position. The bar extends across the door opening in the raised position. The vehicle includes a cable that includes a first end and a second end. The first end is fixed to the bar and moveable with the bar from the lowered position to the raised position. The second end is fixed to the vehicle body.
