I have had my Premium RWD Explorer for only just about 4 weeks and everything has been fine until Monday night. My wife went to start the car to come home from work but it wouldn't go into drive or reverse and a warning message came up regarding the 12 v battery. Ford Rescue (AA) came out and they recorded a voltage of only 9v so a recovery was arranged because car was on an empty industrial estate so not safe to leave there. AA patrol took my wife home and returned to the car later to find no fault ( battery showing 12v) and so he took it to a safe place overnight and delivered it to the dealership in morning.
Car was working but taken on test drive only for the issue to return. Investigation still ongoing to try and isolate issue.
I have been running a Nextbase dashcam via an OBD cable connection as no 12v socket in main cabin. Could this be the problem although not been connected since Monday and had been OK for 3 weeks.
Anyone had similar experiences or any ideas?
Problem with 12v battery
I suppose it depends how big the 12v battery is. EVs don't need a huge one so it is possible your Dashcam killed the battery if it was on all day but seems unlikely.
I run a dashcam but you can get a handy kit which piggybacks off a fuse in the fusebox so there's no damaging existing electrics and if you pick the right fuse it goes on and off with the ignition so won't flatten the battery.
I have an OBD reader which I plug into the OBD port but sometimes it repeatedly trips the car alarm, presumably due to some current sensing feature of the alarm. Is it possible your dashcam also repeatedly tripped the alarm which would maybe put additional drain on the 12v system ?

It's nothing to do with the dashcam but the failure of a module that is controlling the high voltage battery. Part now on backorder from Ford in Germany and collecting a Ford provided hire car tomorrow.
Hope this fault doesn't appear in other Explorers.

I’ve had the Select RWD for a week and that fault has started on mine today. Got no dash cam or anything like that. Car has just gone back to be checked. I’ll be mentioning this thread to them when they ring me.
I'm having exactly the same issue. Got my Explorer back from Ford last Friday after the 12v Battery had fully drained. They thought they'd sorted the issue but the same thing has happened again today and the car has now gone back to Ford.
Has your battery been ok since they changed that module?
Both myself and a work colleague just got delivery of Explorer RWD long range company cars, my car developed the 12v battery fault and had to be returned to ford on a low loader after 4 days. The AA came out and said 12 v battery fault but couldn’t get the fault reset. My colleague had the fault after about 7 days, and called ford assistance AA but the fault then cleared and vehicle then would drive. Mine sat at ford and service centre and they said it’s now not showing any faults. So I picked it back up and drove home…very disappointed
I saw this on a facebook page today.
There is a customer satisfaction program (KZP) due to partially flat 12V batteries.
--------------------------------------------------------------------
25B05 Battery electric vehicles (BEV) of the Explorer/Capri models Update of the module software
SUMMARY
A small number of Explorer/Capri battery electric vehicles (BEVs) have been identified as having a potential software issue that may cause the 12V battery to stop charging. When this problem occurs, a 12V battery charge indicator light will illuminate in the instrument cluster. If the vehicle continues to be used with this problem, the electrical functions may gradually fail with additional warnings. The vehicle may not be able to shift into D or reverse, and eventually the electric motor will shut off while the hazard warning lights remain active. Dealers must update the software of the control module - state of charge monitoring (SOBDM) to the latest version.
