The car should still be under warranty so a trip to the dealers is needed.

A laundry list of apparently unrelated symptoms usually indicates a bad 12V battery, as already mentioned. If you are handy with a multimeter and the 12V battery has never been replaced (3-4 years old), then you could save some money by replacing it yourself, if the readings indicated a bad 12V battery.

A better test would be 2 or even better 6 hours after turning off.

But it could be a failing alternator or charging system.

Not wanting to disagree (a battery is a good shout) but those do appear related (not sure if they are saying the car turns itself off though??) but if not those symptoms suggest something ABS related.

If anything causes the ABS to shutdown all those features are reliant on it. My OHs MG6 taught me that one-a single abs sensor died and even the speed related wind screen wipers went haywire along with stability, tpms, abs, hill hold and the inbuilt sat nav lost accuracy… loads. Not sure where the ZS gets the speedo info from - the 6 had a separate drive on the box so that worked.

100% it needs plugging in. A dealer is your best bet but Autel tools do tend to offer good support for MG after market that won’t break the bank.

Edit: Forgot to say if driving it in that state be especially careful, no ABS can affect the brake proportioning so locking the wheels may be a lot easier than usual.
