Service bulletin B510320
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
WATER RUNS OUT OF DRIVER'S DOOR WHEN OPENING: If the vehicle is parked on an incline (front higher than the rear) water may not be able to flow out of the door. Upon opening the door water may flow out rapidly. The collected water does not run inside the car. The door seal creates such a tight seal that water can't flow from the door.
