I'm 3000 miles in to M3P ownership, and I could swear the motor (not sure if it's front or back) is whining more than it used to. It's a high pitched whine - under part throttle, it's intermittent like a square wave form, and becomes steady under heavier acceleration. I assume this is just the motor regulating itself, but I don't remember hearing the motor at all before except under heavy acceleration.
Is this normal?
