Hi. How do you guys know that the USB turns off after an hour? I didn't see any reference to this in the manual. Just got a 2021 BigHorn and trying to figure out the best path for power to my dashcam. I suppose I can test it. My 12V on the dash has a battery symbol and stays hot after turning off the ignition If the USB does turn off at 60 minutes, I'd prefer to use that since I already routed the cable for the dash cam instead of messing with fuses for the 12V.

It appears my USBs never shut off either. Hours after shutting off truck, I can plug in and charge. My dashcam thinks its a PC. I need to install a USB power-only using accessory power.
When I unplug a device, the 4 plugs have a dim white line surrounding them which now is on. Before plugging in this was off.
Not sure why some trucks are on all of the time.
Once you open your doors, it resets to1 hour again, that could be why you can plug and charge. Though it maybe different from trim to trim.
The 12V on the dash turns off/on with the ignition, I have my dash cam plug in directly to it. Buy a 12V / USB plug and you can power your dash cam from there.
Similar to this, it's flush mounted: https://www.amazon.com/Cable-Matters-Charger-Smartphones-Including/dp/B00MH3USBE/ref=sr_1_5?crid=2FM3TSKUZWC1N&keywords=flush+mount+usb+12v&qid=1645842551&sprefix=flush+mount+usb+12v,aps,148&sr=8-5
Yea that is what one would expect based on the manual.
I waited 6+ hours after turning off the truck and exiting.
Got in the truck, everything including the USB panel, appeared to be off. I plug a tablet directly into one of the USB Type A" plugs. The table immediately started to charge and the lines around the USB port in the truck lit up.
Like others have mentioned, my USB ports are always enabled. Not sure why.
Solution for me
==========
I ended up just wiring an Accessory-controlled USB/Cigarette-Lighter Hub so that I could properly control my Dash-Cam as well as any other devices that I want to shut off when I shut-off the truck n exit.

Thanks for the tip. I know about that outlet.
=====================================
- Here in Florida the "dash area" gets over 160F using an infrared temp probe, measuring from 6 inches. It is a cheap one costing around $100, so the accuracy could be challenged.
- I prefer all of my wires to be hidden.
For me that plug is pointless. But the designers and multiple % of people find it convenient up there. I am an outlier as is referred to in statistics. I spent 6 years as an avionics electrician in the US Navy, so wiring dashboards clean n safe comes easy. Again, not everyone has these skills and/or knowledge.

In the end though!
Agreed, strange that some of us have "always on USB" in our console.
One thing I missed, I do have a 12inch UConnect & eTorque, I wonder if either one of these makes a difference? Not sure why the eTorque would though. But the UConnect is tied to the USB Ports.

I just came across this in uconnect a few days ago. My truck shows a choice of 15 minutes or 1 hour.So no way to stop the one hour delay for the front USB ports used for Android Auto? I recently got one of the devices that plug into the USB and create a wireless connection to my phone. Very useful. But when I stop the car in the garage and go into the house, I get notifications every few seconds on my phone as it's trying to connect my truck back to my phone for an hour even though my truck is off.
Where in the settings did you find this? I see engine off options but that is for just the display, etc. Doesn't control USB. Would love a 15 min option on USB for the same reason (wireless Android auto).I just came across this in uconnect a few days ago. My truck shows a choice of 15 minutes or 1 hour.

this answer was very helpful. thanks for posting. i thought there was something wrong with mine, as the USB light turns back on if i pull the door handle when truck is locked (without key being near me) or if use my key and lock the truck twice, it will turn on after the second attempt to lock the truck. i had no idea how long it would stay on, and i thought it was draining my battery, so i would unlock the truck, open the door, close the door and lock it once and the usb light would go off and stay off, so long as i dont try to pull on the door handle or hit the lock button on the key a second time.The USBs on the center console stay live for 1 hour after ignition is turned off. It's a convenience feature so you can keep charging a cell phone left plugged in, like say you go for lunch or something.
After 1 hour, those USB shut off and will not turn on again until you turn on the accessories, after that, they start the 1 hour cycle again.
The 12V outlet on the top center dash turns off after 30 seconds of turning off the truck or if you open the door right after you turn off the ignition.
I'm not sure about the the USB in the center armrest or the rear USBs for passengers, they either shut-off right away or could also be on the 1 hour cycle..

What is your trim package? I'm hoping I can use alfaobd to get my USBs to stay offNone of my dash usb have power when off
Any success fixing this? I just got one of those wireless dongles also and I'm having the same problem. Have a 19 rebel. Haven't messed around with the fuses yet, that's my next path since I couldn't find any place in the uconnect setting to shut that option off at 15 minutesSo no way to stop the one hour delay for the front USB ports used for Android Auto?
