Technical 2016 500x diagnosis

[Charpe87]

Hello everyone,
A few days ago the car became unresponsive. Key fob not detected I changed the batteries in both fobs. Changed out the car battery. Still didn't work. Pushing the start button with the fob does nothing the dash just flashes key fob not detected. Headlights don't work, door locks don't work ,can't open hatch. Only things that work are the radio, hazard lights and the dome lights as far as I can tell. I hooked up my autel reader and it throws bcm and etm codes. Not sure where to go from here. The car worked fine the day before then the next morning its dead. Attached are the codes. Any help would be appreciated.

Hi,
Have seen a few threads on here from North America with similar issues..

Nothing quite fitting your experience

Are you in COLD temperatures?, a moist climate

Being 6 or 7 years old.... good basic failings in either the Cars 12 volt starter battery, of the main Black cable Battery to Chassis to Motor are a possibility.

Try ruling those out 1st,
A booster cable from Battery to motor could make that difference

Also read further down the 500x section, you will see a few cases

Maybe they help..

Do keep in touch with progress updates

Generally pretty warm and humid here in Louisiana. We've had some cooler days this winter but nothing really under 40F. The day before this happened there was a pretty bad storm that passed through and it rained for at least 24 hours.
