Interesting. I haven't heard of that stage yet. Mine is still in D status...unchanged for 41 days now. It's aggravating that orders placed a few days to several weeks later when they were not allowed to order restricted items are sailing through the production process...while those of us who ordered in the first day or two are not allowed to remove those restricted items (which were not yet restricted when our orders were placed) from our orders so our vehicles will be built. There are some predictions that it may be December before the steel front bumpers are available. I find that hard to believe since, as far as I know, that bumper is identical to the JL front bumper. FCA has a considerable number of unhappy customers at this point...and there has been zero communication from them as to what is actually causing the delays.
Edit: Just spoke with Jeep chat and finally got the first bit of actual information from them after a much longer than normal chat session. They stated that vehicles with the factory steel front bumper will begin production late June/early July. I did not mention the bumper in chat, so this seems to verify that the delays have been caused by that option, which was restricted by about the first day of May.
