My Bolt TPW is also 11/28/16, and I went in yesterday to confirm through the chat function on the gm site. The person was helpful, and just confirmed the same TPW, and when I asked if there was a web site where I could confirm my order status, they said no, but that I could do that anytime via chat, or I could check through the dealer.
The dealer I used to order said the average time from the TPW date and delivery to him(Southern California) is usually 2-3 weeks, but that since GM "shuts down" the last two weeks of the year, he thinks they will try to get as many cars delivered the first two weeks of Dec. as possible. Not sure if "shuts down" refers to deliveries of cars, production of cars, or both, but I'm hoping delivery happens before this cut off.
