No power to ignition

[HemiHP19]

Have 2020 Rebel out of warranty with 66000 miles. Without prior symptoms door locks and ignition will not activate. Battery good at 12.8 volts. Fuses good. Just dead no dash or headlights.

Only prior symptom is occassional tow haul light activation without touching switch.

Any clues how to trouble shoot this?

Update, after 9 days in shop with no power, tech figured out the frequency hub module got wet from a leaking rear window(cracked frame).

After new module is installed, we will see if anything else go shorted out.

Meantime will be $2800 poorer with very little recourse for reimbursement
