I think a lot was based around the 2017 the first batch of the RF maybe it was a bit of a rush to get them launched ? I know of a lot of people who don’t seem to have any problems but when you do mazda are a nightmare to give you a clue my mate brought a kia 2013 at the time I brought my RF he still as his and althoght he has had a problem with it there was no hassle involved in getting it sorted and his was a good 10k cheaper you can only speak from personal experience …
