Traded in my 2011 Durango Citadel on 3/30 for a 2014 Summit.. and love it. I liked Durango a lot, but some of the tech was lacking & uconnect issues were irritating. There was only one Summit within hundreds of miles of my dealer spec'd how I wanted (granite metallic, black interior, v6, summit) and I was very lucky to get it. They had several people make offers on it while it was sitting in lot waiting for me to pick it up, lol. Even GM was impressed by it because he hadn't seen a summit yet.
After reading some of the posts in here, I was nervous that I would run into some issues, especially given how anal I am about everything in general. However, I must say.. it's pretty much perfect. I can usually find something to b**ch about, but after 2 weeks, nothing yet. Uconnect works great, remote app for phone works great, car rides smooth, all features work, no rattles/squeaks, HK audio sounds AWESOME. Only unconfirmed issue is BT audio stream drops sometimes/randomly when playing music, but I can't pin that on UC yet, since I am using a rooted GNII with custom rom.. could just be bug in BT stack as I haven't tested audio anywhere else with it yet.
Of course, before i took delivery, I made it VERY clear that they were to hook up truck to star tool & perform all updates before I picked it up, which in itself may have prevented me from having issues. I work in IT, and there is a reason mfg's release firmware/code updates. Getting your typical mechanic to get on the same page with that mindset is still a challenge, even given how much software directly controls late model vehicles these days. I always make sure they check/perform updates when I go in for an oil change for my vehicles, and it has prooven to serve me well, even though it's a bit of a argument each time. I would suggest everyone do the same. If J2534 adapters & TA subscriptions weren't so expensive, i'd just do it myself, and I think it's ridiculous that it's so hard to keep SW up to date in a vehicle, when it's probably the cause of 80% of late model vehicle issues. There is a 3G radio in system.. would it really be that hard to implement a 'live update' sort of solution???
Anyway, enough ranting. Great truck!
