I went through this recently. 6 weeks into it I'm still in "D" status. It really sucked because I called Chrysler 3 times, and each time they said my Jeep had shipped. WAH??? The dealer showed me on the computer where it still had the "D" status attached to my order. So, the customer service reps where just BS-ing me. Gave me some spiel about only a dealer can give me the status, but assured me my Rubi had shipped.
I got pissed by week 7 and cancelled the order. Found a Rubicon in another state with everything I wanted minus the soft top. I'll buy one of those after market.
I never found out the real reason they were not building my Jeep.
Good luck to you.
At this rate, they will most likely cancel your 2010 order and build you a 2011 in August.
FYI, another poster on here says they shutdown the line in June for a few months to re-tool for the new model year. Looks like you're in for a 2011 man!
