  1. Catalytic converter: When there are problems with the catalytic converter, many drivers complain of a sound often described as metal can filled with rocks being shaken up. The catalytic converter plays an important role in reducing pollution, so you’ll want to look into right away.
  2. Loose heat shield: Many drivers find that the rattling sound is coming from a loose heat shield that surrounds the exhaust system. Be careful working with them, however, as they can be vulnerable to rust.
  3. Items stowed in the car: This may seem like an obvious one but is overlooked by many drivers. Check the glovebox, door cargo compartments, items clipped to the visor and the rear cargo area.
  4. Lack of oil: Some have reported rattling noises when idling being caused by low engine oil levels. You may stay on top of engine oil fill ups and changes, but if a leak develops, it could reach a low level unexpectedly. Read why car engines need oil right here.
