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

Complaint A creaking noise can sometimes be heard when the automatic tailgate is closing/opening. Cause Grease in the upper ball socket (ball socket with larger diameter) of the liftgate control (HKS) drive unit could not be distributed optimally across the ball surface and this can consequently result in increased friction between the ball socket and ball pin. Remedy Smear existing grease in upper ball sockets of drive unit completely across ball surface using a brush (see picture). To do so, the HKS drive unit must be removed (see WIS references).
