We have a '14 Xterra Pro-4X, CPO, with about 60k on it.
At purchase, there was an issue with the volume knob - it wouldn't smoothly increase the volume, it was random and non-linear. Dealer replaced it under warranty. Still, it seemed non-linear, as a volume setting of 3-4 is pretty damn loud, and the scale goes WAY beyond that.
15 months later, the volume knob has failed again. Anyone else dealt with this?
