I love my new element but it has two or three noises that can be annoying. A metallic clank under the hood typically appears in three situations. (1) I back out of a parking space on level ground. The clank sounds when I lightly step on the brack after going forward a ways. (2) Putting on the brake when backing into my driveway. (3) braking while coming of the freeway after going fast for awhile. The basic idea is that the clank is associated with braking after changing momentum (e.g. forward then reverse). You can feel it in the brake pedal.
