Don't bother the dealer they are 3rd wheel in the mix just go to the subaru site and log a owner email with them. My bet is the dealer didn't add you to the subaru database they just took your money and moved on.
Subaru did not contact me with the survey via email until around 3-4 weeks. Give it a little time. You will also get the welcome kit in the mail but it will take a couple months. Our welcome kit with the badge of ownership stuff did not arrive until 2 months later
