Yes, all 3 of the main Promaster and WGO groups. All I've seen so far is a few fan units quitting, or one or the other fan dying resulting in an overheating condition. Several expediters losing theirs but no fire reports.
There must be a pretty good replacement business going on because several companies now make replacement fan modules for these, and they aren't all that expensive
