I'd say that any fault that stopped you getting from A to B or required the car to be in dock for more than a day at a chosen date (ie booked service) or cost you more than a service, should be counted as a major fault. And you shouldn't get any in your first year.
I'd expect rather longer than that - three years at least.
But of course how long any fault takes to fix is often down to the dealer
- and most are just simply dreadful.
I don't know how that version escaped. I'm sure I wrote three years! ;-)
Choose your own if it's better but the main dealer is part of the vehicle quality.
