2014 Crosstour 6 cyl, push button start. When the start button is pushed, the lights on the dash flash very briefly, then there is a click and all goes dark simultaneous with the click.

I tried to jump start with a battery pack. No difference.

I'd start with the easy fixes, by having the battery and alternator tested. Clean battery posts and terminals. Make sure the ground connection to the chassis is clean.

I have a 2015 with the same issue. Dealer says its a relay switch causing a short. FOB, starter and battery are fine.

Check battery voltage with DVM while trying to start. If it drops below 10 or so, you have a battery problem and or a corrosion problem.
