I bought a new GC Summit on 3-8-13 and it had issues. The 8.4 AN radio interface would not save many of the settings for the lights / park sense system / auto dimming interior dash lights etc. Sometimes entire options on the pages would be there one time when you went into it and then not be there the next time you checked. Some things that I would "check" (or select) to be on, would then 5 seconds later, uncheck themselves as you watched. The salesman confirmed all of my issues and the service manager got involved. They contacted Chrysler and they have no answer. They swapped another radio from another one they had that seemed to work better But when it was put in my car, it acted up the same way. The dealer unwound my deal and gave me another car after about 10 days. Now I just got the new one yesterday, and its doing very similar things! I have to think others are having these issues.
