MG ZS EV 2024 charging port door won't open (dead 12V)

[MG ZS EV 2024 PH]

Hello everyone
We came back after a months vacation and now my 2024 MG ZS EVs charging port door won't open, it is still under full warranty (6 months old) and MG assist towing company says they can't tow an EV since parking brakes are engaged, It looks like the 12V battery that powers up the central computer is dead so no signal is sent even for the charging port door to open, I unlocked the door manually btw, so am I right here guys... Any suggestions please. The car was charged to 87% before I left and parked in my covered garage. Please help!!

Connected a battery booster just to unlock the charge port door (no other way) and have started charging it, 12V battery was dead and the main battery it looks like is just fine with alarm and flashing lights which were a welcome sight, hoping the green indicators on the charge port start blinking green for now it shows the portable charger is charging...

That's pretty normal, if you leave for a month you should put the 12V battery on a battery tender.

Sadly the ZS EV does not measure the battery voltage and top it up when it gets low, using the traction battery, like other car brands do.

The 12V battery will need replacing. Will still be under warranty, so sooner than later.

There is a trickle charge from the main battery to the 12V I believe for this car so are you saying that I need an externally connected trickle charge as well for the 12V please when it is left unattended for over a week?.

I would not worry about it unless you intend going away for 4 weeks or more.

Last time we did a 3 month tour of eastern Australia I fitted a 5 stage charger via a time clock that was set to 15 minutes per day to my wife's ICE car that had a suss battery.on arriving home it started first go.
