Well if they do it is not good enough, MCC got away with it in the past because Mog owners just accepted it. 2022 I expect a fault free car, my 7 year old 50000 mile Kia runabout as never been back to the garage with a fault If MCC want to continue to sell cars to younger generations of customers they must up their game or go bust.
Personally, I would formally 'reject' the car under the 2015 Consumer Rights Act. That should get them to pull their finger out and get it sorted pronto - under the present climate I doubt they'd want to lose the sale.
Sounds reasonable....
