The VOTS site (https://www.jeep.com/vots/
) is free from Jeep, you just need your VIN or VON (vehicle order number) and last name. If I remember correctly that is updated once a day, in the morning sometime. In theory your dealer signs you up for email updates when they place the order and input your email address, but that never worked for me. I had to pretty much beat the VON out of my dealer, but eventually received it.
If you sign up for Level 3 or 4 membership here, you get access to the MOTS tracking system that Milous maintains. It updates more frequently than VOTS, has more detail and supports the forum.
