Hoping someone can help me with this. I bought my 2010 3 weeks ago and I have been noticing a humming, electronic sound when the vehicle is idling. It can actually be heard when you are driving but you need to listen closely. You can really hear it louder if you are sitting in the back and you have your head near the back of the console almost at the floor. It can also be heard if you are standing on the outside of the vehicle. I took it to the dealership and they told me it's from the fuel pump and it's normal. They said there were some bulletins on the noise but nothing is wrong. I just listened to my neighbors friends Traverse and I didn't hear anything. She has the exact same one as me. It could be just me because I tend to pick up the littlest noises. Does anyone else hear this noise?
