Failure to start: HV battery shut off

[MJCTHR]

Hi all, I had this issue and was told to turn the vehicle off and then walk away from the car so that the car key no longer has connection to the car. Only then does the cars computer system properly shutdown and reboots when you turn the car back on. AA suggested being away from the car for approx. 10 mins however it may work in less time.

Thanks for all the messages about this problem, it happened to me yesterday. I had just charged my MG5 Trophy in Maidstone after already driving it about 40 miles, went to start the car after and it would only go into neutral and the warning came up. I tried starting everything again about 6 times and was worried I would be stuck there. I rang MG Assist who went through all the security questions which took maybe 6 or 7 minutes, then asked what the problem was. They wanted me to give them the exact wording of the warning so I started the car to get it and it had been cleared and I put it into drive no problem. Thanked the guy for his time and carried on home.

I don't know what happened but could it have just been that it was hot after having been charging and wasn't ready (my phone heated up too much and shut down at one point too as it was a hot day)? Was my time away fom trying to start it what ended up being the fix?

What SOC did you charge to and was it on a rapid DC CCS charger or AC EVSE?

I used the Ionity charging site in Forstall Road, Maidstone, rapid CCS.

I charged from 31% up to 75%. Village Hotel Maidstone | Castle View, Forstal Rd, ME14 3AQ, United Kingdom | EV Station
