While at the dealer, drop your computer off at the Geek Squad and have them fix the punctuation keys...
Seriously, 1.5 years would put you into the range of build dates [listed on your door sticker] where some of those things were not uncommon, where you probably want to make sure you get the TSBs and module upgrades that are available in addition to any repairs needed--for which about all the help we can offer is sympathy and suggest to contact Jeep assist and see if another dealer near you has parts.
Can't say if you really do need a new ACC module, but some folks here have had nothing more than loose mountings on the front sensor. Try searching for ACC or FCW, and if you use google, add jeepgarage to the search strings.

I'd make sure you get the loose ground/firmware flash for the EVIC lighting up.
Plus, depending on transmission, that flash.
