Solved: Dead Battery, instrument panel light stays on all night

Well it ended up being the BCM needing replaced due to moisture in the cab from front rear window leak.

Im having the same issue, my dealer replaced my battery went to pick it up today dead. wanted to leave it for them to further diagnois it and was declined saying there was nothing more they can do. for the amount of money we spend on these trucks we should not be having issues like this.

find a new dealer

what is your truck?

Front rear window leak??? I think my bcm may be the culprit to my issues but I don’t see anything that makes me think I have a leak

2019 Ram 1500 Bighorn. I had the issue of the "Press brake and click start" screen not shutting off issue as well. I got on this forum which helped me convey the information on some of the fixes to the service technician at the dealership. Luckily for me, I still had extended warranty so I dropped off my truck. They went through their own analysis and finally came upon what I had initially conveyed to them and checked out the RF Hub. Once they got to it they found water on it, they traced the water coming from the back window seal and the 3rd brake light seal on the top of the roof. Both Brake light and Window seal had been leaking with the rains we been getting and also when running the truck through the car wash water slowly seaped in the truck consequently landing on or near the RF Hub which is located on the back of the backseat of the truck. My Extended warranty initially covered some of the parts but because the issue was due to a faulty seal on the brake light and window seal the Service Advisor had Chrysler cover all the replacement parts/ labor/ and fixes on my Truck. Now I have my truck back with no issues. Thanks to those who previously posted the RF Hub issue which did greatly help the Service Tech come to the same conclusion. Good Luck Guys on getting this fix on your Truck.

My 2024 3500 is in the shop for the lights & steering wheel controls as we speak. Had to have it towed there yesterday due to dead batteries.

I am having the same issue with my 2019 Bighorn, although mine is continually turning on and off. Did the replacement of the RF Hub fix your issues? Also, did it kill your battery?
