2 month old ZS EV LR - several faults and now HV Battery Shut Off

[maskull]

Dealer had nothing available. I didn't push it this time. Hopefully all will be well now but how do you get the courtesy car from the AA?

When my MG 5 went in for investigation the dealer gave me one of the many courtesy cars on their forecourt. Depends on the dealer I suppose

Since buying my MG ZS EV late February I've had minor faults appear on I would say 3 out of every 4 journeys. They don't stop me using the car but they stop ACC from functioning.

• Auto Emergency Braking System Unavailable
• Pedestrian Auto Emergency Braking Unavailable
• Vehicle Control System Fault

Not very worrying as I say. However today the car shut down completely mid journey with ...

• HV Battery Shut Off

Fortunately the car stopped in a relatively safe place - Christ knows what would happen if that was on a motorway! Several attempts to restart the car failed, taking it through stop, lock, wait, unlock, start (foot firmly on brake). RAC were called out and the guy was able to get it going by ...

• Plug in computer to car port
• Check and clear all faults
• Remove negative terminal from battery
• Wait 10 minutes
• Reattach negative terminal
• Restart car normally

Since the above I haven't had a reoccurence of the minor errors but we'll see what happens over the coming days. The car is booked into my local MG dealer in May to investigate the minor faults. Needless to say this has shaken my confidence in the MG. I hate to imagine my wife using the car by herself on the motorway and the HV battery shutting off, bringing the car to a fault.

Has anyone else had this issue? I will contact the dealer tomorrow and get their advice, but I want to know what caused this and whether it's likely to happen again.

Hello
Buy a 10 mm spanner to remove the negative terminal. Had to do this once in the middle of France at 2am as I had plugged in with the car still on

I've had my ZS EV since June 23 and after the RAC showed me the remove negative lead reset, I carried a 10mm spanner in the door pocket and used the "trick" approx every 3 months and makes the car feel like new again.
Problems I've had and all fixed with neg lead reset.
Unable to reverse if car is forward on an incline. (This was first that prompted call to RAC)
Regen braking mode 3 not working.
Strange problems of car keeps braking with nothing around (sensors all clean)
Random ICE not working and Home button reset not working
Door / lock /unlock madness.

My partner refuses to drive my car because of this. Her Honda has none of this nonsense.

Yes I've put one in the car.

Good to have this as an emergency action, but to me it's not acceptable for a brand new car to have these issues. We should not be simply tutting and saying "it's the computer what can you do".

You need the official MG accessory then...
