This is just a temporary fix, limits the maximum charge level. They're still investigating the issue and coming up with a proper fix, they just know that it's happening to fully charged cars.
For what it's worth, I popped out to our Bolt this afternoon after getting the email, and tweaked the max charge level to 90% from the panel. Easiy done.
Wait, shouldn't you be charging to 80% in normal circumstances anyway, because keeping the battery at 80%+ for long periods of time deteriorates it faster?
