I would definitely say that you have something bad in the charging system, that could be the cause for all your problems. Should be 14+ while the truck is running regardless of rpm.

Is it possible if you can tell me if there’s a new flash for my ram. I saw there was a November 1st update someone posted that added knock sensors to the flash. I attached my last update number @Jimmy07

@Jimmy07 if possible can you tell me if there is a flash that’s currently newer then this one posted, I had one preformed on the 9th that needed with a O I believe

So currently we have 2 software updates available.These two have a whole host of updates for mulitable modules within the harness assembly.Each one of these modules are processors that act like a computer in it’s on right.This Alanitis Hi is very fast in processing speed.These software updates provide in new lanaguage so as to correct many stored faults that are occurring..Not all trigger a MIL light only certain ones that effects engine emission and driveable. One MIL light that seems to be recurring is a Auto/Stop relay # 3 stuck in closed.This will trigger a MIL Light.Also no ORB reader will clear any MIL Codes in this Atlantis Hi due to this highly restricted gateway.Only a Chrysler’s dealership can.Also I notice people pulling the battery cable either pos or neg thinking this will reset all.But this will not do this at all.You just trigger a loss of power for the tech to fiqured out why that happen as well.So long story short these are just software updates.I see this also in many other makes and models and year.So applying lemon or dealer trade will just push the can down the road..So patience with this next gen Ram I call it a 6th gen for sure.Also this Atlantis harness is also in the 2022-2024 Jeep Grand Wagoneer is also experiencing this issue as well.

UPDATE!

Got a call back from Ram today that they will not move forward with a buy back. I asked them about updates on my truck and they just said to contact the dealer. I haven't heard from the dealer yet after leaving them a message earlier this morning. I need to find out if I'm going to have a loaner when I'm back in town tomorrow. I'm going to call Ram tomorrow as well and see what else we can do and also talk to the dealers manager.

You are allowed a rental from the dealership’s fleet for the first 12,000 and then depending on the issue warranty will continue a fleet rental for you.The reason for denial for buyback is and Ram does not feel you have given the dealership enough time for the repair.One must realized not all tech’s have gone to school on this Atlantis Hi harness assembly and it is been on the Jeep GW for 2 years and not many people can afford a Grand Wagoneer L yet.So hands on is learn as you go type with tech support on the line.But dealership are sending them it is just not in large numbers maybe one at a time since there is such a shortage of tech’s right now…Also careful with a dealer trade the numbers may not come out like you would want them.But currently Rebel manufacture money has increase to 5000.00 now up from 4000.00.I myself I say stay the course.

Yeah I really don’t want to trade in and take a hit. I was hoping ram would just let me switch it for another truck. It’s been at the dealer three times and a total of 6 weeks now. Apart of lemon law, I’m wondering if I should just keep trying my luck on getting Ram to do something else?

Ram said no, have you contacted a lemon law attorney?
