I drove again with the read armrest down, and while the cupholder doesn't make noise ALL the time now, it still occasionally rattles on larger bumps.

I just had this TSB done on my 03 V6 Limited. We didn't notice the rattle because we rarely drive with the rear armrest down. But, one time it was down and the cupholders inside were rattling with every little bump.
