My truck was dead this morning and it wasn't the battery.

The strangest thing happened today. I went to work, and my truck was dead, I mean completely dead. I had zero lights, and my doors wouldn't even unlock. I had to use the key in the keyfob to get into the truck.

Again, ZERO lights on anything. I thought this was strange because even if the battery had died, I should have some power to at least get the dome lights on or the green light on the ignition button.

Naturally, I could jump the truck using my wife's car. I popped the hood, and all the lights turned on as if I had just opened the door. The truck fired right up like nothing was wrong.

Two things to note: I generally don't lock my doors when I park in the garage, and I have it set where the mirrors fold in when I do lock it. The mirrors were in the open position, and it was almost as if the truck locked itself.
Also, I threw my sunglasses in the truck yesterday, and they happened to land on the wireless phone charger. Is it possible that the metal on my sunglasses resting on the wireless charger put the truck in a "safe mode"? I assume that the wireless charger would have no power when the truck shuts off?

Why would releasing the hood unlock the truck to power up? Is there a reason behind this I don't know of, or was this one of those head-scratchers that will never be replicated or happen to anyone else?

Did you put a meter on the battery and test it? Same with alternator?
No - I looked at the battery gauge on the truck and it was at 14.5.

I’ve been driving around and running in and out of a few stores and starts right up. I didn’t lose any radio presets or system changes I made in the settings either. I would assume if for some reason the battery had died or lost contact with the truck, all of those settings would have defaulted back to factory settings.

I'm not sure about the gen 3's, or my own gen 1, but i know on my jeep when I disconnect the battery, the presets are all still there, just saying.
