Does anyone know if Nissan has a Servive Bulletin for the rattle noise in the rear sub-woofer. Any information would be greatly appreciated.

I dont know about a tsb, but I complained about noise from the rear sub speaker, even when the radio is off. So they found that the

" trunk rods rattled. Repaired the trunk torsion bars and reinstalled properly. "

and now the rattling is almost non-existent. It sounds much better, so far so good.
