I have a Model Y that is only 3 months old and I was in rural northern CA last week when my car died. They towed it away and I've been told it is the rear drive unit the has been detected as having failure. They will replace when a new one comes in in a few weeks. Any advice on what to look for or expect when i get back my car? I'm hoping this will be the end of it and also hope they will deliver my car since I'm 400 miles from home and can't take more time off work to retrieve my new car. Any input is greatly appreciated
