I'm sure it is getting better, but some of those are risky.
"Sudden battery death syndrome" is a lead acid 12V battery thing and has nothing to do with lithium EV batteries. Not sure what that's about

As for replacement, it extrapolates 225 of an unknown sample of 15000 vehicles, then mentions that it's old Nissan Leaf and Model S batteries.

The older Nissan Leafs uses a different chemistry and had no thermal management. Leaf batteries lost capacity at crazy high rates that aren't even close to what current EVs see. Add to that the Nissan Leaf range was only 75 miles. If you lose 35% after 8 years you're down to 49 miles. That's terrible, but not comparable with any other EV sold in the last 5 years. Teslas lose about 10% of range after 150,000 mileS (240,000km). It's just not reason for concern with current EVs. My Pacifica Hybrid (Plugin Hybrid), still has 100% of the capacity it did in 2019 when I bought it.
