I'm going to go all "Negative Nelly" ill await the standard responses.
If you take the faults the car has, of which there are numerous, obviously there is no real pattern to what models can get what faults, if any.
Some niggles, some dangerous and some that are now a bit of an embarrassing saga (an oil leak that has been dragging on for nearly 5 months)
Put all of these aside and the single biggest fault would appear to be MG UK themselves, there is zero customer support and there is now far to much evidence for even the most ardent 4 owner to dispute that.
Any customer care team that says "we sold it to the dealer it's their problem" is just a disgrace.
There have been numerous members slag of other brands in their defence of MG but even they must read some of this and agree now.
There will as is the norm for this forum probably be some examples forthcoming now of crap service elsewhere from other manufacturers and the usual my car is perfect stories. ( I genuinely hope it is)
That doesn't solve the issues with MG though, as
@Retsiba said it really needs all the owners to be united, I'm sure if all the cars that are great just now develop a fault, hopefully not by the way, the owners would expect a level of service from MG then, things would obviously change very quickly if the shoe was on the other foot.
As someone who was initially quite excited about ordering a 4 I think the most disappointing thing for me, varying levels of quality control aside, is MG themselves they launch a potentially great car, that gets good initial reviews, but they completely miss a trick with putting the correct support and service in place. Will it impact sales? Probably not, there really is nothing that can compete with the 2 SE s and people will still take a chance on a budget entry level EV.
The big thing and it is completely unknown at this time, is the long term impact on used 4s, all used EVs prices are now falling, from the ridiculous false used prices they were at. How will the market react to a car with some questionable quality control and poor after sales care as I said nobody really knows.
Hopefully it improves soon.
( No I don't have a 4, yes I still come in here, yes I still have a reason, no I won't go elsewhere, yes I complain about MG quality and service, I am not alone!! Oh your aggressive DM, telling me to leave the forum, makes you sound really tough, not! )
