What the black cover underneath the front end of the motor on the left driver side? It's hanging down. How important is it and what does it do? How can I have it repaired?
It's probably important to not have hanging down, possibly getting caught on something. I'd say one of the clips or fasteners has come loose that holds it on. Have a shop reinstall or crawl under the car and inspect it.
It is called a spoiler, forces air into the engine compartment, it should be functional at all times.
