Less than smooth switching of some gears? This has been reported by many reviewers and is being addressed by Mazda via a software update, according to my dealer.
BTW, the 2nd issue commonly pointed out by early reviewers and owners, that of poorly tuned suspension, esp. rear. This is also being addressed, my CX-60 (scheduled for production on January 31st) will already have improved suspension, but earlier production units will have the suspension replaced at no cost - I have it in writing from my dealer. I don't know, however (and there's some discussion about it on CX-60 forum in my country) if an owner will have to proactively request such improvement; most probably yes, it's not treated as a recall.
