I bought my 2017 new 6 weeks ago and the Sirius still doesn't work. Only channel I get is 184 (preview). Sirius insists it is activated.
Not a big deal since as it is rather useless anyway (had Sirius on other cars).
My 2017 SXT is a 5 seater. Most of the dealer inventory is 7 seaters. A large part of the reason I bought it is because it doesn't have the third row, which is pretty useless. All of the competitors only come as 7 seaters if you want V6.
