This is interesting. We bought a new MG4 EV in Australia. Same thing happened it just broke exactly like yours. the dealer who sold us the car in Gateshead Newcastle, NSW. Is saying it is not covered by warranty and they don’t believe us it just broken when being adjusted normally. the dealer is refusing to fix and MG Australia has not returned our request for them to contact us. I was so looking forward to getting this EV car. I’m not confident that any future issues are going to be addressed by MG. I’m hoping this isn’t the start of more things to come. I’m interested to know if warranty covered your vehicle in UK.
