New member hoping you guys can help me safely jumpstart my 2019 Hyundai Plug In. The start battery is stone dead after leaving the four way flashers on during a flat tire fiasco yesterday. I would appreciate any tips and tricks that you have!

you may want to see if you can put the 12v that's in the trunk/hatch area on a battery charger. as for jumping I think many of us carry one of those 12v lithium portable jump starters. To minimize the risk of this happening again, leave the car in the on position. our cars have super tiny 12v batteries.
Once I was reorganizing the junk I carry in the car when going camping and had the hatch open for maybe an hour, that was enough to get the 12v battery drained so it wouldn't start the car or would make the car flash many of the warning lights until I used the jump starter to help the car turn on, then it was fine charging the 12v battery by itself.
Before I replaced the battery it got to the point where I installed a quick disconnect for the jump starter onto the battery terminals.
