My CX-9 engine bay generates high frequency whining noise when the speed is over 40km/h. The noise is louder and louder while the speed is faster. The problem is only related to the speed no matter acceleration, deceleration or steady speed.
The problem is similar to this TSB related to transmission. But the TSB is not applied to CX-9.
Does anyone experience the similar noise as me? I recorded and uploaded a video. Please share your experience if you have similar issue.
