Just had my 3rd survey from Mazda in as many weeks. First survey was the "how do you llike your car", yada, yada, yada. My second survey I mentioned the hood shake. What I'm seeing is the rear of the hood shake from hinge to hinge over a rough road. The third survey was a targeted survey of specific problems one of which being hood problems, but it only asked about three specific hood problems, none of which had anything to do with the shake and there was no allowance for comments. Nice to know there's real interest in customer satisfaction. Overall I'm really pleased with the vehicle, even survived a 5 minute hail storm with half inch hail and no paint damage!
