The only PCI I'm pretty sure isn't broken is the Wind Chimes... unless the sound it makes has gone missing.
I know the Uber Toilet also works fine, as I've used that since the big change where you have to upgrade it to self-cleaning in order to get the animations to run.
I don't have any pets in the household (yet), so I can't test out the Auto Feeder to see if that still works or not. Last time I used it, I had to upgrade it so that it filled the bowl automatically until the food ran out, but I forgot the specific steps you had to take to upgrade it so that it would do the action. If you didn't do it exactly, the object broken. I don't think they ever fixed that either.
Oh, and I just remembered: The Composter no longer waters potted plants... :(
