Sunroof problems

Just my opinion, but checking/clearing the drain tubes ought to be part of anyone's regular maintenance if they have a sunroof. Dribble a bit of water into each tube and if it doesn't flow cleanly, clear it out using some moderate thickness weed whacker nylon "wire" or similar.

I don't know the specific vehicles you cited, so maybe they're worse setups than others, but for most vehicles the problem is solved with the above maintenance.

Edit: here's an example of the technique: https://www.youtube.com/watch?v=CIaZ_3qMhvM

 

Toyota's have had sunroof problems for years... I have had a few that leaked, all around the drain tube design... they clog & get kinked.
