I noticed a little black hose with a white plastic piece hanging out from under the car in front of my front left tire and i just need to know what it is. I read about it and some people say it has something to do with air intake?

Good morning,

That hose looks like it is from the air pump. that is the air injection pump that puts additional air into the exhaust for additional burning of gases after the cylinder firing.

Is there any issue or complaint?

I would get it replaced. it will set a code eventually and that will effect your emission testing.

Call the dealer. they will look it up for you and they will have pictures for you.

Take your picture with you to help identify the hose.
