I cannot start the car,

You are still under warranty.

Heres a video on how to gain access to the trunk with no power and also where to jump start the car. http://www.youtube.com/watch?v=9gm3U46TnS8

I am having the same problem on my 2014 Equus it wil jump but most of the time if I open the trunk with the metal emergency key the power magically comes back on.

I was having this same problem and I first noticed this issue when it rained, once I turned hard, say like backing into a parking spot, all the electronics blink off but come right back on. But now its tending to stay off longer. I also went into the trunk to check the battery connections and when I touched the ground wire I heard a click sound. The power came back on.

I need to change the ignition starter button but the air bag is in the way is there another I can go there an take out the old button an snap in the new one
