Also sometimes on my 2025 all this electronic junk is problems, mine would not start and I had done nothin to it lately...turns out as someone told me here just press extra hard on the brake pedal and then it started. LOL :/

Your bucket is not falling asleep,,, if you have your key fob within I think it’s 25 feet overnight it will keep searching for the fob and not go to sleep,,, could be other things as well like something plugged into one of your USB ports, there are settings in your head unit under lights and doors that will let you turn off the sensing issues and even tell it to turn off the interior lights and USB ports when you get out and shut the door,,, there’s a lot of great videos that explain this on YouTube, I had low battery issues sometimes in the mornings but after changing the settings on my wolf box digital review mirror and the settings in my head unit my truck seems to fall asleep just fine now,,, good luck and let us know what you come up with!

I've known this for a while. The start sensor is on the master cylinder not just the brake light switch.
Thanks but what I have is a phantom issue

Who says the batteries are good? Tested how? Torqued to what?
