Official summary
"this bulletin provides a repair procedure to address customer concerns of a rattling sound coming from the point where the seat belt buckle is attached to the seat frame. The sound may be heard from either seat on acceleration, deceleration or going over bumps. The sound is more prevalent when the seat belt is buckled but in rare cases, can occur when the belt is unbuckled. The service procedure involves removal of a toothed washer and replacing it with a spring wave washer."

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.
