Dodge is no different than most other manufacturers when it comes to big ticket repairs. Even Dodge usually does well when the cost of replacement items is under $5,000 or so. When you start getting into the tens of thousands, it requires many hoops on both the dealer and manufacturer's side to get items approved. In this case, you have to learn how to play the game. I'm someone who has some recent history with this and my C8 (4 transmissions and an engine out service for a blown compression ring on cyl 7). You have to remain engaged and civil up until the point the timeline extends past 30 days.
Again, I'm in FL and the Lemon Law requirements differ per state. But, I know that they have 30 days here to offer an actionable plan to get your car fixed or firm scheduled inside of that time period. If they start blowing that timeline, then you file that with the Lemon Law board and like Moses parted the Red Sea, you get your car fixed within 1-2 weeks of that board letter being sent to the manufacturer.
That's why I mentioned the crate Redeye engines on the DC store. That's how I got my driveshaft fixed on this car. They quoted me 60-90 days to get a new DS, but I found available driveshafts on the DC store. I then went to the service manager and said, "Here's the deal. You told me 60-90 days, but Lemon Law says 30. They'd likely accept a 60-day plan with a firm timeline, that if you blow that 60 days, then it'll be a buyback on day 61. Or, you could upchannel this through your warranty contact and get me that driveshaft from Direct Connection and have me up and running in a week or so?"
They ended up ordering the DS on their own dealership's dime and billed Dodge for it in their own way so they didn't have to go through the hassle of the Lemon Law claim to start with. I had their loaner a sum total of 11 days... not 60
The issue here is that their parts availability for warranty work only looks in that specific inventory bucket, if you will. The Direct Connection store is their retail inventory. So, when a service advisor polls the part availability, they're only looking in that internal availability bucket, not the retail store (because they're not supposed to). However, when there are parts available there, they CAN be transferred back into manufacturer inventory. They have to file some kind of a request with Direct Connection to make it happen. They won't do this under normal business operations, but they will to avoid things like buybacks. Stuff like making you wait for a long block when they have full engines available is kind of stupid, I agree... but it's just how business is done these days. I learned this trick from their parts manager when going through Mopar parts bin hell with my stripe kit. He heard about my driveshaft and he's the one that told me to go back across the building to service and tell them about the DC store driveshafts and to just put in a transfer from retail to warranty service and voila... problem solved.
