Mine has done this multiple times and then the next cycle it clears. Dealership checks it with no codes stored. They told me to bring it by when the light comes on, but since it happens about once a month, I'm not close to the dealer when it happens.
It seems to me that a connection could be...
On my '25 Limited Night, I've been using several things to close my tailgate. I've either pushed the button on the tailgate, just give it a shove and it shuts, or use my fob to close from the cabin.
