Lube what bushings?

From a search I've found that most new cars have no lube points. The whole system is sealed.
That's really irritating since both Subaru and Hyundai service departments listed it as work to be done. They listed lubricating doors and locks as a separate task.

I have found that you should lube bushings with white lithium grease. My question is, what bushings and where are they?

Thanks.
