Hauling our newer Dodge in for a knock. It’s been an issue for a while but never seems to do it for them at the dealer. I think it’s a bad lifter. They say it’s normal and won’t damage the engine. In my experience it doesn’t take more than a few seconds to fill up lifters. Last Saturday I started it up and the noise wouldn’t go away. Seems like we are always having some type of issue with our two new vehicles (2017 & 2015) but the old stuff just works.

Bilbo,
Sorry to hear that. After my 2006 F250 gasser was stolen I was looking around for a used truck. F250/F150 Super Crews are not cheap around here. Found some inexpensive Dodge 1500's 4 doors with Hemi's. (A little older than yours.) Many of the cheap ones where suggesting the truck had a knock, lifter issue, or camshaft issue. Watched some video's many folks complaining they needed a new cam and lifters at 130,000-190,000 miles. So clearly RAM had some going on with the Hemi power plant. So steered clear and eventually found a decent deal on a F150 super crew. So I would not take there dismissal lightly and push them to fix it and under warranty or split it if out of warranty.
I have found often to get the action you need, you have to -
1) Try another dealer who is more accommodating. Some dealers don't like discounted warranty work. Others just are better at getting it approved. Or have seen dozens like yours, now they just tell you what is wrong and you can address it.
2) Ask the dealer for Dodge's district manager's contact info. Often the dealer will try to avoid doing so, rather suggest they will call him. But ask that he calls you. You could call Dodge directly and try to find him/her too. He has the power to say fix it we will pay or split.
3) Recently I helped out my father in law. His Chevy 4500 box truck tranny went out at 63,000 miles and under 3 years. (Warranty was good to 60,000mi, but this truck should have made it to at least 90K.) It threw a code that is not erasable with a OBDII scanner. (New laws) So you could not drive the truck. Truck delivers furniture so light and easy loads. They said $7,500 to replace it but you get a 5 year 100k warranty. (Guessing you need one!) I said have Chevy call me, this is ridiculous. Then the dealer said if you want Chevy to assist you have to pay to remove and tear it down. (On the hook for $3K) But if Chevy declines you eat the tear down because we only replace. I said do it and tell Chevy here is his list of Chevy cars and work Van's he has and does own. He is happy to go to Ford if Chevy won't step up when their trucks don't even make it to 90K. They basically called back a few days later and said Chevy will split the cost saving my father in law about $3,800.
So get ready for battle. There will be some games but stick with it! They know they have to make you happy if they want to sell you another Dodge. (Even if you don't plan to buy another one!) Doubt this is a one off they can dismiss as "We don't see that often".
