i have the excact thing on my carI feel like he's talking about the hood release under the steering wheel. It's a common problem. Just find a t handle tap wrench, cut some of the plastic away and tighten the wrench around the rod.
Here's a pic of the wrench: http://usaknifemaker.com/media/catalog/product/cache/1/image/9df78eab33525d08d6e5fb8d27136e95/t/-/t-handle-tap-wrench.jpg
You can find it at lowe's or a home depot
