Recently started hearing a 'humming' noise from engine. The best way to describe the sound is when you hear an off road vehicle driving on a regular road... you know that hummmmm the tires make... that is the noise we are hearing from the engine compartment after 30mph, no sound at idling, no sound under 30. It is def. not the tires making this sound as when you roll the windows down you are not hearing the sound coming from the tires. Plan on taking to shop this week but was searching the net to see if anyone else had this complaint.
