I have a 2022 ram 2500 6.7 that I bought in March. 3,000 miles and this makes the 2nd time that it will not start. When I press the start button it says that the entire truck needs serviced. 4wd system, fuel filter, transmission, just about everything flashes on the screen. Also the P for park flashes continuously. This is the 2nd time it's had to be towed back to the dealer. The first time they just reset the computer, but that obviously did not fix it. Does anybody have any idea what it could be? Also the uconnect 12 is very glitchy so they ordered a new screen for it.
 
Make sure all the fuses are fully seated in the fuse box by the driver side battery. Also check for loose ground wires. There’s one in the driver side front wheel well and along the driver side fender alongside the battery that I have noticed.

Great information. Thank you
 
I have a 2022 HD 6.7 litre RAM which won't start. It has 38K miles. It was recently at the dealer having the transmission replaced (yeah, believe it!) and sat for a month.
After retrieving the truck, I was out of town and it sat for 2 more weeks. My son was recently driving it. Now it won't turn over. Battery issue? If so, do I have to replace both? Thank you in advance.
 
Start with battery. Shops often allow battery to xtsi6. Always think simple first. Try Jumpstart
 
There’s a TSB out for some 2022 trucks with no start / no crank issues. Has to do with a non-conductive nut that was installed on the starter. Check your date of manufacture and see if this applies to your truck:IMG_6755.jpeg
 
Thank you for all of the information. You guys are great! I swapped out both batteries (DieHard Platinum AGM Battery: H7 Group Size, 850 CCA, 1000 CA, 140 Minute Reserve Capacity, For High Electrical Demands) ran me for $550.00 installed from Advance Auto Parts (I installed them myself). Pretty much, plug and play. 10mm ratchet wrench for driver and passenger side. Plus removal of crossbar and battery accessories. Installed one at a time to avoid losing radio programming etc. No issues. Thanks again. I hope this helps anyone looking to replace their batteries.

Did they find the issue? I had the same problem with about the same mileage. They ended up replacing the entire wiring harness and both computers.
 
I just started having this similar issue this morning. I'm still under warranty ~ 18k miles. I'll be pissed if it's the battery as a 3 year old battery should not be failing, and I'm sure dodge will end up not footing the bill.

These battery's are known for having a short life especially if you don't use the truck as a daily driver. Some have not gotten a year out of them i seem to be lucky as my truck was built aug 2019 and i still have the OEM batteries.

With the limited use your truck gets it sounds like you should have a battery maintainer for when the truck sits.

Same as you, oem so far. Truck sits a lot but stays on a tender. I know the time is coming soon.

Did you ever get a final answer on this. My 2023 is doing the EXACT same thing you described. I'm already $1300 in diagnostic charges from the dealer and they still don't know.....

It should be warranty?

I'm over my basic 36K mile warranty - just hit 38K miles... of course. Still waiting for an update from the dealership to see if they have figured anything out.

If the engine is not starting I would assume that should be powertrain… but they will wiggle their way out of covering it likely

What’s the solution to only a click when trying to start?

If you're getting a click it's likely the batteries. My '23 w/ only 30K miles on it the stock batteries died and that's all I was getting.
