Hi, I have a '17.5 Maxima SV and I recently noticed a whining noise every time I touch the throttle in Park, Drive and Reverse. It continues with the input of the throttle but fades away once you go above 1.8k RPM. I made sure the audio system is turned off too as it does kinda sound like a long beep. Not sure if my Maxima is equipped with active noise cancellation or the engine noise amplifier, which may be the culprit.
