I took ownership of my MG4 SE SR in late October and I've now covered 3800 miles. I have exclusively been using expensive fast chargers, which is still working out better than my former ICE vehicle (an Audi A2 petrol).
When I picked my car up, I asked my MG dealer to literally go through the list of common faults from this forum before I accepted it, and it has basically been fine.
It is a cracking car to drive, gets the efficiency I expect given the different driving styles I adopt, and it being winter. All in all I think it is a bracingly well built vehicle, and represents excellent value for money. It is also just plain fun to drive - I recently took a Model Y rear wheel drive for a test-drive around favourite roads, and can honestly say the MG4 SE SR is more fun, it is lighter, and reacts better to driver inputs. Build quality is excellent.
The only issue has been the 'keyless' entry stopped working recently, which my dealer checked when doing the recent software update last week. The issue with the handle is only if you press the button 'at the top' where as it works if you press it 'at the bottom' it works - the dealer will be looking at it at the next available opportunity (early March), and provide a courtesy car whilst it is with them. Great customer service.
There appear to be a lot of repeated complaints and moans on the forum for whatever reason. My experience has been that the car is excellent. Sure some of the software could be improved... I'd personally like 'camp mode' and 'dog mode'... but software improves over time. From a hardware perspective the car has been great so far. I know the handle will be fixed under warranty, and for now I just use the 'unlock button' on key fob, as I've done with every vehicle I've owned, except those early models where you had to physically insert an actual key, before jumping in, manually adjust the choke etc. The EV experience is completely different, and the MG4 is an excellent EV at a bargain price point.
There is a reason the MG4 scooped up so many awards. It is a great car.
