I've been hearing a rattling noise coming from my car when I drive at high speeds. What could be wrong?

It's possible that the engine mountings are loose and vibrating against the engine, causing the sound you're hearing. You can check this by gently shaking your steering wheel while driving and listening for any change in the sound of the engine. If there is no change, it may be time to have the vehicle serviced or checked for other issues.
