Good Morning.
I was very excited when I picked up my 2006 Ford Escape yesterday. Then I got on the highway to drive home....yikes!

I had a headache by the time I got home! Yes, I test drove it, but it wasn't this noisy when I did! It's a hum that gets louder the more I accelerate. I mentioned it to the manager after my test drive and he did a cursory check of the tires and said they were fine. I am bringing it back to them, but thought I would just check in here and see if anyone had any ideas what might be causing it. I absolutely love this vehicle (aside from the hum) and pray it's something they can remedy easily and quickly. Thank you for your input.
