USB port stopped working all of a sudden

[theblet]

Hey everyone,

weird issue here. I drove to work this morning (about 30 min) and used the USB port with lightning cable for CarPlay. No problem. I get in my truck to come home, no connection. Not even charging my phone. Switched cables, switched USB ports, turned truck off and back on, nothing.

Put the same lightning cable into my 12 v charger and it worked fine.

so when I got home I let the truck sit for about 2 hours, and went try it again.
Worked fine.

Any ideas about this? Obviously wasn’t a fuse because it started working again.

Thanks!

There was a thread about this just a few days ago. Thermal protection was the consensus, I think.

Dang I searched for awhile and didn’t see it. I’ll try again. Please post it if you can thanks for the help

It was really hot today too. Heat index in the 100’s

That used to happen to me a lot when I first got the truck, anything over 100f outside and I knew the USB wasn't going to work. Fix for me was getting my windows tinted. Hasn't happened since.

Same thing happened to me yesterday. Worked fine in morning and then wouldn’t at lunchtime. Then after work it was all okay again. 2021 longhorn limited. 2200 miles.

Having a similar issue with the 3 most forward USB ports, the two near the cell phone holder and the one inside the upper center console. Drive 2.5 hours from Austin to Houston in the upper 80s with overcast and rain most of the drive. All three ports didn't work the entire drive. Tried the same lightning cable in one of the rear USB ports facing the back seat and that worked. 2021 Laramie with 1200 miles.

Try my wife's car for size. The Rear view camera is crap quality. In 90 degree weather not only with it flicker wildly, but you can also get the BSOD, Blue screen of death.......

For $240 part they can fix it.

Update: I tried the lightning to USB cord that came with my iPhone and another aftermarket cord and they both worked in all of the USB ports. I plugged in an adapter to the DC port and both cords worked there as well and the AC port using the Apple adapter cube. Looks like I was using a brand new, malfunctioned, cord.

22 limited 2500 and cooler temps. Rear usb ports haven't worked for a week. Is there a separate fuse?

There is a thread about fuse boxes on here. As I recall, I think I saw rear USB listed. It lists circuit breaker 5 as rear/ console charge only USB. The picture has no CB 5.

Edit: The link posted in that thread is different than the 23 owners manual. For 23 anyway, there is no CB 5. Fuse F48 feeds rear USB. Check your manual.

I have a 2019 dodge ram 3500 laramie and have been having the same problem, my USB ports would work for a while and then stop. Couldn't use my phone through them or play music on a USB stick, any ideas?

I would change the USB media hub.

I’ve noticed that mine doesn’t work when the temp outside gets over 102… when at 102 it kicks on, if it gets hotter, it cuts off.. idk if mine is an isolated incident but that’s my experience

I have had this happen to me once, maybe twice on my 2021 Limited with 107k miles. Always went away when I turned the truck off and got back into it later.

What year is your truck? Sounds like the usb hub
