I bought a 2021 Dodge Durango Citadel last spring and both fobs were already showing low battery messages from day 1. We replaced the batteries right away but the warning still flashes now and then even when the fob's range and remote start work fine. I asked a coworker with a 2020 model and they said they've never seen the issue, so now I'm wondering if there's a software update I missed. Could the system be misreading voltage levels or maybe something's up with the sensor in the cabin? Has anyone tried getting the dealer to reprogram or test the fob with their diagnostic tool?

@RONIN 0 sounds more like a communication or sensor issue for me. The system might wrongly interpret the voltage, or there could be a minor glitch in the cabin's key fob detection sensor.
Your coworker's 2020 not having the issue suggests that it might be specific to your build year or a batch of fobs/modules.
my advice is to push the dealer to use their StarScan (or whatever diagnostic tool they use now for modern Mopars) to check for codes related to the WCM or key fob status

Does this happen all the time or just occasionally? If you have the fob in your pocket with your phone for example in front it will block the signal. If you're concerned about an update, you can check the latest version on your Durango and compare it with what Dodge has on the website. It's a bit of a bummer your out of the warranty period, so the dealer may not be too interested in helping you out. I think your best bet would be to take it to a shop that specialties in Dodges.
@YeeHawBro thanks for the input. I agree, it feels like a module or sensor problem since new batteries didn't fix the warning. I'll try to book an appointment with the dealer for a scan sometime next week.
@CrushTest1 the warning happens randomly a few times a week. I've made an effort to keep the fob away from my phone but the message still appears. The specialty shop is a very good alternative if the dealer isn't helpful due to my warranty status. I'll look into the software version myself before calling anyone.
