I have a 2022 Rubicon 4xe 12v battery under the hood dies, been having this issue for 6 weeks..
Now i have 2 major issues and the dealerhip is of no help..

Took my jeep to the dealership they replaced the battery as they said there is an issue while there they
inspected and reprogrammed the battery back control modiule BPCM
routine to disable/enab battery control pack module -witech
inspect and reprogram module, integrated dual charging IDCM

My amp reserch xtreme power steps no longer work
Battery dead when i picked it up at the dealship dealsership claims that the amp research are connected to the battery and kill the battery over nite along with the popmotorz switch back fender lights.

Per the dealership the dealership there should be nothing to the 4xe jeeps aftermarket, as they products create a draw and the battery and killed it....Hmmm can you tell me what the draw was when the mechanic put a meter on it to confirm the draw? he didnt this is what he cam up with...Needless to say i am done with the dealership and jeep is getting a bad name... i did inform the sales guy the 2023 GC4xee we were discussing isnt happening due to service... The service manager can you confrim the steps worked before the vehicle came in yep... pull the video of me pulling in the bay you see the steps are working, he says they are not responsible for any after market products and they only support OEM as they are provn to be the best products... Jeep lost a sale to GM over this deal...

I am going to order a new control module for the amp power steps as i am expecting they put a power surge thru the system repromgramming this is why the steps do not work. If anyone has thoughts please let me know

There have been lots of people with amp power steps that have had parasitic draw issues. I see it pop up in the 392 groups quite often too, so it isn't 4xe specific.

enought to kill a battery overnight? while plugged in charging?

Does your battery die overnight if your steps and other accessories are disconnected? My amp power steps plugged into the OBD port on my Ram so they could know when the doors were opened. I suspect there is an incompatibility going on where the steps are keeping your Jeep from going to sleep or something along those lines. I had a VW Golf once that I forgot to unplug the OBD tuner module I had installed. It killed my battery in like 2 hours just because it kept all the computers awake the entire time.

Sounds like the title of this thread should be changed to "Amp Research power steps draining my 12v battery". Doesn't seem to be an issue with your 4xe factory equipment.

I am struggling with it being Amp as the the dealership did something that the boards quit working, and battery was still dead. I had to pull the fuse wait 15 min and pit the fuse back in and the boards work now no issues.

Is there an option for a larger battery on the 4xe ?

There are certainly much better 12V batteries you can drop in, the stock ones are crap, try the X2Power AGM’s from Batteries+.
I went with Batteries+ Duracell branded AGM made by East Penn/Deka after I found the OEM battery was dead one morning, yes also made by East Penn but to Stelantis specs, haven’t had any issues since.

I can saybit isn't the amp research power boards, removed the fuse on them last night and battery was dead again this am. Had a remote start has been disabled and had the red turtle and stalled 30 secs later. Only thing left non stock is the marker lights I mentioned and the tazer jl mini. Once I have the lights unplugged and unmarried the tazer mini I am going to a different dealership and see what they can do.

Even sitting idling radio and climate off and lights moved to off hybrid mode ICE running engine generates 2kw and battery says -1kw on the hybrid electric page.

Not convinced this is something after market next steps is to replace the OEM battery and go from there.
