I posted about this in the Hellcat status thread - read through the last 10 pages or so if you want some valuable info and a gauge of what to expect moving forward.
As for your order, I’d bet dollars to donuts that your status change is a direct result of what I posted about earlier today. Long story short, they’re having problems with the vendor that makes their WB panels. For some reason, they got a bad batch and fitment has been less than fantastic, so most of the parts are being rejected and sent back. The vendor’s working on getting replacements, but that takes time. This is why NB orders have been flying off the line while many WB/JB orders are stalled or even moving backward in status progression. Guys that were scheduled for builds in the near future (like me) are seeing ESDs moving back by a week or more in many cases.
No big deal. It’ll come.
