I may have spoken too soon. I was searching for the chat icon (lower right corner) while logged in. No matter what page I went to it would not show up. Later I noticed after clearing the browser cache and heading back to tesla.com, this time unauthenticated, the chat button showed up almost immediately. So I made a snap judgement, something I hate when people do .
I do want to point out I eventually did chat with an associate and the support I received was excellent.
