I bought a used (with low mileage) 2013 S and noticed a humming noise when I exceed 75mph. Is that normal? All other functions appear to be working well.
I recently purchased at 2013 S which, allegedly, comes with life-time free charging. Yesterday, I charged it and was billed (only $1.50) but free should be free. Wondering if anybody else has has a similar problem and how it was resolved.
