I've had my CX60 Homura for 22 months (13,000 miles) during which it has been off the road for five days for numerous software updates that have eliminated many teething issues, generally fixing annoying things like the initial lack of reliability in the facial recognition system, accuracy of EV range forecasts, reducing the excessive sensitivity of safety warning systems (etc). I was given a free car replacement, so this has been no great inconvenience.
Inclusive of this, three major parts updates under warranty have been (1) installation of superior noise installation, (2) the fixing of the "sticky steering" issue and (3) TWICE updated suspension, plus a wider recall for various lesser updates (hybrid engine management system etc). Now it is a superb car, and I speak as a former owner of Jaguar, BMW, Audi etc.
There is little doubt that Mazda got much wrong at the CX60 launch, notably suspension and (door) noise insulation. However, I have been patient, worked closely with my dealer (remember it was a new model and learning curve for it too) and now I have a car that I adore and intend to replace with another CX60 (or CX80) on its third anniversary.
I have never considered it a was a bad car (Jaguar/BMW/Audi all had their foibles too). It just needed a little more refinement. Reactions to the improvements to suspension will inevitably be subjective. But it is noticeable in other forums that the levels of dissatisfaction have fallen beyond a few voices. I should perhaps mention I am a UK owner with UK dealer.
