Dead battery and bed light turned on

[RHO_Tres]

They're working on getting me a loaner, but they said because I bought it from Mark Dodge and not them, they are having issues locating me a loaner.

At least they're honest about it lol.

Both batteries failed and replaced this morning. They said nothing came up in the draw test. Picking it up later today so we'll see.

Good luck I really hope this fixes your issues.

It will fix them one way or another. I've decided that if these fail I'll replace them with non-OEM batteries one more time to rule out that as the cause. After that I'll trade in and cut losses which unfortunately means a downgrade in some direction - probably a Raptor.

Just happened and for no reason? Battery had to be charged so maybe from a low battery?

Yeah, I started looking at the Chevy 1500 ZR2's with the small diesel or even the Colorado's ZR2's with the AEV package.

Had the new Colorado ZR2 before this...the engine is meh, angry sewing machine. Plus no Sport Mode...boooo. One of my favorite looking trucks though!!

Dealer saying my BCM (Body Control Module) is failing, but it could be due to failing batteries.

Observations:
1. Truck dead in the morning for no apparent reason.
2. Charged batteries for 24 hours
3. Start it and drive it
Lights up like a Christmas tree with “Service Transmission” and solid illuminating CEL, illuminated Serv4wd, and can’t use dash for shit. Seemed to run fine but couldn’t change drive modes.
4. Took immediately to dealer and verified the transmission is fine, it’s this BCM code (which I think started with bad batteries). I asked them to change them out which will allow the truck to reset anyway, tomorrow should learn more.

Separately they have another RHO in for repair for a parasitic amp draw, they suspect the electric shifter. It has been there for nearly 50 days!! What the fuuuuuuuuuck?

Hoping I receive good news Friday and can get back to ripping up shit!

So far everything seems ok with the new batteries. I can tell you I'm not a fan of wondering what's gonna happen when I push the button though.

Yep, I can’t figure it out. When I hook up the solar charger, it shows about 25%. After a few hours in the sun and charging, it shows 75% or more. Then I start the car and the battery shows around 13.2 - 13.4V. It doesn’t go higher than that anymore. Got a 250 mile trip tomorrow, see if that changes anything.

Just like you guys, my truck has died 3 times. The first I thought it was the issue with keeping the keys by the garage door while it was parked overnight, so I started putting them all the across the house in my bedroom. Then it dies again, but I thought that might be because I left it parked in the garage for 10-14 days and I read on here that that can drain the battery also. Finally, the third time it died, I jumped it and took it to the dealer and it's been there almost two weeks now. They tested both batteries and they said that they are fine but 1 of four modules is bad which is causing the battery drain?

Oh, and apparently one of the modules they need - ABS Module - 687-08521AB is on a national back order so they can't fix it and can't give me an ETA of when it will be fixed. So, I'm stuck driving my wife's suburban around. I love the truck, the engine has more than enough power, the transmission is great, and the interior is amazing, but I hate that everywhere I go I'm always worried if its going to start. And this is on a 2025 Ram RHO, Level 1, with only 4,400 miles on it. I purchased it this past January '25 from Mark Dodge.

I've started looking at Chevy 1500 ZR2's or even the Colorado ZR2's with the AEV package to replace it with if i can ever get it fixed.

This is EXACTLY what happened to me. I can't even begin to explain how much it hurt me to accept that my truck was a problem child but I also can't explain how much anxiety the RHO caused me. Every morning, I would hold my breath starting the truck then hope no errors popped up. I lived like this for about 4-5 months. Couldn't do it anymore. The Raptor is not nearly as fun as the RHO (I already want to tune the Raptor so it feels like it has some balls) but I also never have a second thought about it starting or not/throwing random electrical errors. I am old enough now to recognize I need a functional vehicle first, a fun vehicle second.

From someone who knows, I am sorry you are dealing with this and hope it works itself out for the best, one way or another.

The weird thing is mine always showed over 14.3-14.4 even on the bad batteries. It was like they could accept the alternator charge but lost it quick.

Interestingly the new batteries are showing 14.0-14.1 max.

Agree in midsize pickups the ZR2 is Bad A$$.

Dealer assigned a STAR case for it. Looks like this is gonna be a long wait.

I'm going to contact the dealership this morning to see if they have a ballpark idea of when I'm getting my truck back. And you might have convinced me to take it straight a chevy dealer

What is a STAR case?

Dealer phones a friend because they can't figure it out. STAR case gets a Ram engineer involved. It's not a good sign.
