I just had my tensioners replaced. Apparently what happens when they go bad, the engine makes a very annoying whining sound. It will not go away until replaced. Im no technician but my service advisor told me they used plastic tensioners. They wear out or break causing the sound. Motors are covered under powertrain until 60k. No cost repair. Tensioners are replaced with a teflon tensioner. Parts/ labor covered fo 12month/ 12k miles.
