A KL refresh has been announced for 2016, presumably for the 2017 MY. I wouldn't expect a revolution, just minor tweaks. As others have said, the model is selling too well for major changes. A full redesign is still far away, probably not until 2019 and the 2020 MY.
With 6,000 km, I have been extremely happy with it and (knock on wood
) have had zero problems so far.
