Hybrids arent the only ones going into deep sleep mode, the ecoboost does as well. I think the battery is just a piece of crap.

if you've done the Battery Monitoring System reset (which is extremely easy to do), and it's still going into deep sleep, then honestly my first thought is that you're probably right. The battery probably is crap.

If you want it replaced under warranty you have to convince a dealership that it's crap and then hope they replace it with AGM and not EF. Or, you can just buy a AGM battery yourself, I like the cheap Everstart ones that you can get at WalMart.

Up in Alaska we had a local battery manufacturer, Alaska Battery. They simply made them right and they were proud of it.

They put xtra thick plates and other heavy duty stuff in them. They cost about 50% more than a Diehard or something equivalent but lasted like nothing else. I had one in my Ford Ranger for over ten years and it never failed once. That’s a lot of very cold starts.

Wish I could find something like that in the lower 48.

Doesn't the EB. have a different 12v?

yes, it's an H6 size. it can be Enhanced Flood (EF) or Absorbed Glass Mat (AGM) but the AGM battery is vastly superior. I haven't seen anything but the EF dying prematurely on ecoboost trucks, but that's just my observation.

12 volt socket stays on for 90 minutes after turning off. At least my hybrid does.
No it does not.

When my Hybrid is turned off the socket still has power (just like the radio) but as soon as the driver door opens it is not powered any more.

You have to somehow lead the dealer toward replacing the 12V battery. That has solved my problem on two occasions 5000 miles apart. A battery can test good one time and fail the next so the testing has to be performed multiple times. The voltage threshold for certain systems is very narrow. I say replace the battery first, then troubleshoot all of the complicated stuff after. Keep in mind however, even batteries off the shelf can be bad.

A lot of stock batteries may be weak or defective in a bargain basement vehicle.

It may be this simple.
The deep sleep happened to me. I swapped the 12v battery to a new one and have never had a problem since.

My 23 hybrid the cigarette lighter plug stays on for 90 minutes key off and out door open and closed. Just confirmed this. So don’t just make blatant comments that it does not.

My outlet stays hot after exiting the truck. Just went to Florida a few weeks ago and every time we got out it was still on when we got back in because GPS was still up and running. Not sure how long it stays on though but if I remember correctly, someone checked the bed power source and it was like 90 min.
