Disconnected my battery recently to reset adaptives and try to recover lost performance (about .3-.4 on the 1/4). Upon reconnection, Auto mode hp setting is stuck in 797! I can reset it to 500, but then Track and Sport are also defaulted to 500. If I shut the car off and start it again, the Auto mode reverts to 797hp setting. Also, usually moving the shifter to Manual changes hp to 797 (maybe due to Custom setting at 797)? Moving the shifter doesn't do that now. Also, the Power Chiller works in Track set at 500hp. SRT tech at the dealer wasn't able to change it back to normal. Trans also shifts clunky into gear from park or reverse. Any ideas?

Did you get the RF module upgrade yet? Seen some odd ones on my ‘19 rewb since then.
How long was battery unhooked and could battery be getting close to end of life?

Low battery can cause all sorts of weird problems on these babies.

Battery was not low and is about a year old, replaced by the dealer, not to say it can't be bad but doesn't act tired or defective. I had it unhooked for a while, maybe an hour. Was definitely unhooked long enough.
I don't know about an RF Module upgrade, but after the visit to the dealer the startup screen is different than it was, shows the option to choose driving modes which was not there before. It is definitely a software thing. Puzzling.

Maybe they did the valet mode security update that was wonky to begin with. Would certainly ask exactly what was done with PCM and SW updates. I seem to remember a UConnect OTA update a few months ago too.

Give it a couple days and it'll come back.
