They've also done another hardware revision for the charge port, I believe V2 was released earlier this year (Jan/Feb?), a mobile service tech came last week to fix a couple things and he replaced my charge port with a new V3 part. Apparently the locking slot is much wider than the one in V2 which helps lock the J1772 in place. I believe the motor is also more powerful and will still unlock in ice. So I'm not sure if that'll still be the case with anyone with the new part installed.
They also replaced the two little plastic cylinders that go around the two metal prongs for power in the charge port, apparently there was a design change for that as well, since the plastic cylinders would snap out if the charging cable tugged on it during disconnection.
