Saltwater corrosion resistance is a bit above and beyond what a car needs to be designed for. Even boats need to be cleaned out well after a day in saltwater! It corrodes nearly everything it touches.

Saltwater corrosion resistance is a standard test in automotive for all ECUs.
I agree - the twitter thread didn't really have any details. How many EVs are we talking about? I searched around a bit but couldn't find any other details.
The interesting thing to me is the whole idea that these battery packs (whether in an EV or as power wall or as a utility level reserve) can catch on fire if they get wet enough and that leads to the right kind of corrosion. It seems like this has implications for how power walls and utility reserve banks are protected from flooding.

Florida might have 58000 Teslas (https://michiganstopsmartmeters.com/how-many-teslas-are-in-f...). If 1% were submerged in a given year, and 100% later caught fire, that's 580 potentially horrific structure fires. If it's 1%... then it's 5. Florida has about 50,000 structure fires per year (https://www.myfloridacfo.com/division/sfm/ffirs/sfm2020ar.pd...).

It's not a big deal, but it's good to know I guess.
Some of those EVs were damaged from debris and leaked all kinds of hazardous materials into the flooded areas. Nobody is talking about this yet.
