I had similar on my '05 Ram. Battery kept going dead. No parasitic draw issues while testing.
One morning I go out to the truck and the radio is playing. Truck is locked and key is in my hand. Open the driver door and the "key in ignition" chimes start up.
WTF??
Give it a smack under the wheel and it all stops. Took a video of this happening as it did this more than once.
Changed this and no more issues since.......... View attachment 1715952702
It did do the same thing with the previous battery, which is how we ended up with a new one. The old one got pretty tired after dying so many times. I'll see if I can find another battery to swap in.
