Highlander Hybrid Humming Noise at Highway Speed
Just bought a 2013 Highlander Hybrid a week ago. I have noticed a faint, intermittent humming or buzzing sound, particularly at highway speed that comes and goes with acceleration and deceleration. It sounds "electrical" in nature. Is this normal for this car (my first hyrbid)?
