Official summary
"this bulletin provides a repair procedure to address a customer concern of a rattle or popping sound which could come from either of the rear door opening areas. The sound may occur over small bumps or when a twisting motion is introduced into the vehicle body at low speeds. The cause is an insufficient gap between multiple layers of the body structure where they are spot-welded together as shown in the illustrations below."

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
