Regarding the WL75:
They are definitely having issues with parts just like any other manufacturer.
However, the QL delete has proven to be more about the profitability than availability.
They never deleted the QL in MY2021 with the SR package or V8.
Now the QL is back on all Overland/Summit including V6 , mainly because the MY2022 has about $2K more in Price.
Look at it from another perspective, you can go today and order a V6 2021 that will require the QL delete, but can order the 2022 with the QL as standard. what's the difference??$
If this was really JUST a supply chain issue, the 2022 V6 would still carry the delete.
Is QL definitely back on the recently built L's? Mopar Insider and others covered when they quietly removed and deleted without notifying anyone, but I haven't seen any discussion of QL returning. Mopar Insider also claimed even SR's had the QL deletes with $750 credit given in it's place, and claimed that Jeep said it was a chip shortage issue.
