You seem to carry a heavy chip on your shoulder, and beyond that, the extreme emphasis on various words in your writings appears as if you're trying to yell at people. Certainly negatively treating people by criticizing them, or the time they took to respond to you will get you nowhere. If you feel the need to block people, then I'd deem you as a person is cannot take criticism for your actions. There are many ways to approach a group of people, however, your way certainly seems toxic in my opinion. One thing for sure, this is not your typical group of Instagram or twitter posters. We are simply here to help one another with the sharing of information regarding this particular vehicle.
Regarding your initial query, keep in mind a few things that most manufacturers are not going to implement half-year changes in their production streams. Why? because those changes cost an extraordinary amount of money. Think about the number of meetings, decisions, and people involved with getting said changes ready to implement into a production line. Beyond that, you have to work with suppliers to implement changes in their production lines. What about costs associated with those changes? Do they get passed along to the consumer, or are they absorbed? My point is that what your asking for is simply not the norm unless it's likely some sort of dire emergency fix.
The only manufacturer that I can think of that may have done this was Volkswagen with some of their products, where they'd come out with half-year updates. They'd always name the vehicle with its year + .5, for example, 2004.5. I'm not even sure if they still practice this, however, I suspect not.
My point to all of this is that there will probably be no changes to any of the FCA vehicles during a particular run just because we roll into a new year. I am not in the manufacturing business, nor do I have any sort of insight into any manufacturing business. Just my own opinion.
I'm more than happy to provide input to anyone or share my experiences and happy to do so, you just may want to consider how you approach other people.
