Not all 290K or whatever Model S drivers are all here on TMC. Even if they all were, not all of them are reporting DU replacements when they happen.
From Two Thirds of Early Model S Drivetrains May Fail By 60,000miles from Dec 2015:
Edmunds had their Model S DU replaced 3 times (2013 Tesla Model S Long-Term Wrap-Up | Edmunds). 1st was for noise. 2nd was for total failure. 3rd was for noise again.
I haven't watched all of, but at ~4:40 he mentioned the bearings are shot and the splines are wearing out. I've seen the same two issues mentioned about the gen 2 Rav4 EV DU (supplied by Tesla). You may want to listen to the comments from 0:20 to ~1:08.
Last time I checked this was the Model 3 sub-forum which uses completely different DUs than the S/X.
