I had a low battery voltage warning on my 2020. Come to find out, Ram had an update that fixed the issue. Well, it didn't technically fix the issue. The update just expanded the parameters so the voltage warning wouldn't sound.
You were an early adopter! You posted that 9/14 and most people didn't have that issue until November. Do you know what voltage was showing before you started the motor? I stopped getting the battery warnings about two weeks ago, apparently because of an update. Before, I had around 11.6V, now about 11.8-11.9V--slightly better, but I wonder if they just changed the warning cutoff instead of fixing the underlying issue? The display is red when I check before starting. Is that because it's below 12V or is it always red when the motor isn't running?

I haven't had any trouble starting so far. I'm about to take off on the shakedown cruise, so I hope it doesn't strand us in the desert. I am taking a battery booster just in case!

I was an early adopter, but I'm pretty sure mine was a different issue than what everyone else has experienced two years later. I got a 'low battery' warning back in 2020. It was one of many updates the dealer installed at my first oil change. I don't know what the voltage was prior to the update.
Yours is also the only non-'22 I remember seeing that issue on.
