Driver side door lock does not work with remote or electronically inside vehicle. Also heated and cooled seats went out the same time. Dealers says it's over $1000 to repair these. BS!

The door locks intermittently lock with key fob and sometimes do not unlock. It's very random. If you lock them all by hand, a different door or doors will unlock with the key fob.
