Drove car 2 days ago now everything dead
Over last 5 hours I’ve held reset button down 4 times for 10 seconds- door latches etc still not functioning. Was going to jump it -pull cable unlatches door but as door goes up window prevents door opening & you have to get into car to unlatch frunk

i just had the same thing, 2-3 weeks ago. Had to jack up passenger side with low profile long reach jack ( https://smile.amazon.com/gp/product/B00L1ZCN0I/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1 ) remove front wheel (Look at lug nuts post https://www.fordgtforum.com/forums/threads/socket-for-titanium-lug-nuts.37152/) and remove wheel well, pull the push pins out and it removes fairly easily. Look forward for battery, pull red positive terminal rubber boot and reach a jumper cable in there. I have a lithium boost battery pack, started the car and lowered the damn windows, and left the doors open. Open the front cover (frunk) and block the latch with a towel.! Had 1.4 volts and would not charge. You will need that battery terminal access to the load the car after another jump. Mine is 3 yrs +, how old is your car? Pm me if any other questions.

Had the same problem few months ago, the ford dealer guys came took off the front right wheel to access the battery.
After that I alway keep the front latch open whenever the car is left to park even if the trickle charger is plugged in the back, I learned my lesson.

Just FYI there are battery power terminals in the engine bay. No need to disassemble the front wheel well.

Where in the back? On the “old ones (2017)” too? Can it carry the 7+ amps to get the car to life?

I think the engine/storage compartment battery terminal (standard 12-volt plug) is only on 2019 and newer.

I own a 2019 and mine is located in the back right corner under this cover. I am not sure about 2017-2018 models. Karl might be correct and the 2019 model year could be the first year.

Chris,
Do you have a cigarette 'lighter' charger in the storage compartment?

My almost daily storage habit is to: raise wing, lower driver’s window 1/4”, and plug maintainer in. Even though I may drive the vehicle the next day, I have piece of mind knowing I can access all areas of the car.

I do same but I also pull the hood release lever and pop the hood to the secondary latch.

Leaving the hood popped would obviate the need for cracking the window?

Yes, but it is a "backup to the backup" just in case....
How long are the lithium ion vehicle batteries supposed to last?

“Yes, but it is a "backup to the backup" just in case....”

And what if it is parked at the mall, and it might rain? Windows open and frunk released? It needs a high current terminal access in the rear and a battery booster stored in there. I will be looking into that.

Ok. I do not pop hood or leave window down in areas where I cannot watch vehicle.
I do not use my vehicle as much as you do.
I only have 7,100 miles on ODO.

Since our cars are 2017's a "power point" in the engine compartment would be nice.
From reading this thread the newer models have the power point?
