Flash no start

[Rick.C]

I have a 2015 with 3.8. Engine light had gone on 3 weeks after buying car. Checked codes, minor vacuum leak and lost communication with FCM u0109, but car still started and ran. Tonight car started but had several warning lights, "brake, abs, collision avoidance, auto hold." Turned car off, then on, same condition. Fuel level was low and warning came on about low fuel. Arrived back home, shut car off to run another scan and now, warning lights flash, dash flashes, headlights flash, then goes back to neutral state. Going to order and replace module. Anything else I should look into?

8 weeks in. Has been running fine. Then, push start button and everything flashes like battery is low. Ran codes, very small evap leak and the dreaded u0109 FCM, but got that before the no start. (FCM on order). Disconnected dealer tracker, charged battery at trunk to 100%. Same issue. Will start with jump pack or jump cables under hood location. Has anyone been through this? Thanks for your help.
