I've had my Touring for about 10-days and I'm hearing a humming noise from the front when the car is on. I've heard this humming since we got the car but it was from the inside and is was low so I thought it was normal. Today is the first time that my wife was outside the car and she heard it much louder; then I listened to it. It sound like this humming is coming from the front electric motor. I contacted customer service and they are going to set up a mobile maintenance service call. Has anyone else had this problem?
