High-voltage Battery Pack Malfunction Indicator Lamp

You're probably rushing the start. e.g this thread

Thanks for the reply. I had a look through the linked thread. I’m pretty sure I’m not rushing the start sequence, but I’ll keep that in mind.
Also, just clarifying it’s the red HV battery malfunction light that came on, not the yellow HV cutoff warning lamp. The manual says

“This lamp will illuminate if a fault is detected or the high voltage battery fails. Please contact an MG Authorised Repairer immediately.
This lamp will flash if the high voltage battery temperature is too high. Please stop the car as soon as safety permits, switch the vehicle power system to the OFF position, and
leave the vehicle immediately. Contact an MG Authorised Repairer at the earliest opportunity.
If a high-voltage battery pack relay adhesion failure is recorded, this lamp flashes. Please contact an MG Authorised Repairer as soon as possible.”

Sounds kind of serious to me.
I’ll book it in for a check at the dealer just to be sure.

A low 12 volt battery can throw up random warnings. Worth looking at.

I have an MG4 and have been getting the yellow warning message for the last few months and it used to disappear. 2 weeks ago the car would not drive at all and had to get MG Assist out who could not resolve it either.
Car was towed back to my local MG Dealer and they have been trying to resolve this issue for the last 2 weeks.
The have carried out numerous software updates but to no avail.
Currently have a courtesy car and they are liaising with MG directly to try and resolve the issues.
I took it for a test drive yesterday as no error had appeared on previous test drives over the last 48 hours and 12 miles into the drive the light reappeared. Back into the garage for further updates.

Hello Kiwipower,

Just letting you know I've got the same red no drive code with a HV pack code as well when connecting to CCS charge. Not the same as yours (occurred when connecting to a CCS charger) but I'm keeping an eye on your thread for info and you or others can see mine at: Red Power System Malfunction Warning.

Can you say which dealer in case it's of use to the one I use to contact them?
