Try changing your aux cable first, if that doesnt work then more likely the aux jack has spread loose internally. This happened to me, as I would leave the aux plug in all the time. I ended up replacing the jack, it was super easy to swap out and not that expensive. Your maybe a bit more as you have the usb port, and the 2008 only has the aux.
You start at the rear of the center console, take out the ashtray grab a firm grip, and a good amount of pulling force pop off the rear plate from the back. From there you will see the back plugs of the aux outlet and the cigarette lighter. Unplug the aux, and push it through inward (its only held in by clips) into the cubby box, and install your new one by just pushing it into place and plugging the connection.
