Wow. Never thought I'd ever see a recall on these 'fall-off' parts. Winnie has been using this method of using epoxy only to hold brackets for decades.
Mine is a '02 and when the first part on my RV came loose due to the brackets epoxy giving way (in 2016) it was the lift up engine grill support bracket which came loose (rear of the RV, covers the engine access), I read all I could about it and found that they'd been using epoxy for years before my model year. Saw some extensive write ups about prep'ing and replacing the epoxy but also read where the new epoxy would let go for some owners within a couple years. Didn't seem like a good idea to use the same stuff to hold the brackets in the same locations where it had let go once already as it appeared from mine that the broken off bracket would have some of the fiberglass stuck to it, thinning the fiberglass. While looking at the issue, it just made much more sense to me to use screws as the pieces the brackets held were all light weight. I can lift the entire wrap around lower rear cover on my RV with one hand, for example.
My browsers won't open the link to the nhtsa.gov link and I'm wondering if it only applies to the Vista model, and just for the hood piece? Or is this one of those cases where the bracket tends to fall off onto the road? None of my loose pieces fell off, though it was close in a couple cases, and I started using screws on brackets that hadn't loosened up as preventative.
