Honda Civic seatbelt adjuster rattling noise issue at ear level on Honda Civic

Some Honda Civic owners report experiencing a rattling noise from the seatbelt adjuster at ear level, particularly noticeable when driving over bumpy roads or at higher speeds. This noise is often attributed to a loose fastener in the seatbelt adjuster area or the retractable seatbelt mechanism, which can contain a rattling ball when not engaged. To mitigate this issue, some drivers have attempted to use soft material tape, sound deadening materials, or dielectric grease on the seatbelt height adjuster. Others have tried applying pressure on the headliner to see if it alleviates the noise. If the rattling persists and becomes bothersome, owners are advised to contact Honda Automobile Customer Service or visit a Honda dealership for further assistance.
