MG4 keeps aborting AC charge

[DavecUK]

I had the same problem with mine 1 year ago...the dealerships normally like to waste your time and assume it's your charger. Fortunately I had a neighbour with an MG4 EV long range. My Charger was a Rolec, his was an Ohm. The symptoms started innocuously enough with me thinking sometimes I may have not put it on charge, but gradually it got worse until it would only stay on charge for around 1 or 2 min before cutting out

• My MG wouldn't charge on my Rolec, kept cutting out, his would
• My MG wouldn't charge on his Ohm Charger, his would
• My MG wouldn't charge on MGs own granny charger
• My MG wouldn't charge on a BMW i3 charger

The garage suggested it was my charger, then it was both my charger and my granny charger, but when I gave them the above information, clearly they could no longer blame anything and everything but the CCU and booked it in for "diagnostics". So don't try and totally prove it to the nth degree...just enough for them to book it in. This is because they will do diagnostics and have to before MG will approve the work. I was without use of my car for about 5 or so weeks. As although I had it at home, I only had enough electric for the journey back to the dealer (long story).

My view, expressed before, if you buy a new car (or a used approved), if the car is off the road waiting for parts/repair selling dealerships should be obliged under law to supply you a replacement vehicle (courtesy car). If they don't have one they should hire one for you. Otherwise, this makes a manufacturer warranty worthless.. Modern electric cars don't have the same parts supply chain we used to enjoy a few decades ago. I had an early i3 where the safety box had failed rendering the car undrivable. This part wasn't available and had no lead time. It was almost 3 months before they could get the part. Fortunately they gave me a courtesy car during that wait. Dealerships today no longer seem to have courtesy cars (in the same way cars no longer have spare tyres).

It is all down to decreasing margins and cost pressures. Courtesy cars are much less available these days as they represent stock that is tied up capital.

AFAIK there's no right to a courtesy car in law, it is a "courtesy" that a good dealer provides. If it was required in law, then the costs would simply be passed on to the sticker price, so everyone would pay hundreds of pounds more for their cars.

Some would want that, some would rather have a lower price. I suppose it could be at the customer's choice?

But then you are basically making a deal with that specific dealer which may or may not stay in business long term.

My point being there's no free lunch here.

We could have an unlimited warranty for 10 years on everything, guaranteed equivalent courtesy car, pick up from your home and/or mobile mechanic... etc... but it would all have to be paid for somewhere.

The 3rd party dealership where I bought it from have taken it to be looked at and will liaise with MG to get it sorted.

In the meantime they’ve given me a courtesy car. I did ask them if they would pay me compensation for using rapid chargers, less what it would cost me to charge at home but they said no.

I think that's as good a result as you can expect.
