2022 TRX – Uconnect Custom drive mode reverts to Auto. Uconnect support says BCM bug. Anyone fixed this?

[Hun1313]

The dealer said Uconnect is up to date, and wanted to charge for further diagnosis.
• Uconnect support told me it’s a known TRX bug. They said the PCM isn’t responding to the Uconnect request and the BCM needs an update.

1.Has anyone had this fixed with a BCM flash? Do you know the bulletin or software number?
2. Did the dealer charge you? How much?
3. Did anything else fix it, like a Uconnect reset, a telematics box change, or a screen update?
4. Does the tune cause this, or is it separate?
I’m trying to avoid paying for blind diagnosis, so exact part numbers or bulletin numbers would help a lot. Thanks!

It’s a known bug that was introduced in a Uconnect5 update. We all have the same problem, and there’s no fix - other than replacing your unit with one that hasn’t been updated. Or, even less likely, seeing Ram get off their dead asses and fixing the problem that THEY introduced.

New screen with update?

Hey @RamCares My truck just did the update (I’m a 2022 level 2) It changed the performance pages screen. It sucks. Anyway to get the old screen back? I’ve attached the new screen

I Can No Longer Tune Drive Modes on 2022 TRX

I'm the original owner of my 2022 loaded TRX, virtually issue free so far. I hadn't driven the truck for a couple weeks and encountered an issue today. The battery is fresh, voltage is fine, and the truck stays on a Battery Tender. I started it and as always changed the Drive Mode to...

It's not actually reverting back to Auto, it just indicates Auto on the big screen. The EVIC will show the mode you selected. It's a minor issue IMO and certainly not worth trying to fix yourself or a worthless trip to the dealer.

Did some work on it ask the uconnect customer care and dealers they said uconnect sending the info but bcm is not receiving. So bcm needed to do proxy reset.
Tried on alphaobd but dint got any luck. Now lmk if any know how to do aproxy on it.

But when you want to do custom mode, you can’t program it. I liked my sport transmission and having my traction control on. That’s not possible anymore. I can switch it to sports mode but traction control is disabled. It reverts back to auto on the Uconnect screen but displays sport on the dash. The problem is that I can’t program my custom at all. I really don’t care if it reverts back to auto on Uconnect screen. I just want to be able to program custom.

Yea. It sucks. Ram doesn’t care.
And it’s just going to get worse. More blacked out screens, more radio failures, more dancing screens.
