Cars: Cars: Red's Tune-up Blues

It's a beautiful day, and Red the fire engine can't wait to work in his garden! But as soon as he leaves the fire station, he hears a pop, pop, pop—he needs a tune-up! But Red has never been to Doc's before and doesn't like the idea of being poked and prodded. Lightning McQueen and his friends do their best to convince Red to go see Doc, but nothing they say seems to work. Will Red be able to find the courage he needs to go in for a tune-up?
