Hi Emily, the rattling noise could be caused by a number of things such as loose exhaust components, worn out suspension parts, or even engine mounts. It's best to take your car to a certified mechanic to properly diagnose and fix the issue.

Hey Emily, check to see if the noise is coming from the engine or under the car. If it's coming from the engine, it could be due to a faulty timing chain or loose pulleys. If it's coming from under the car, it could be a loose heat shield. Again, it's best to have a professional take a look to determine the exact cause.

Hi Emily, have you noticed if the rattling noise only occurs when the car is cold or if it gets worse when you accelerate? It could be a sign of a faulty catalytic converter or damaged exhaust system. It's important to address this issue as driving with a damaged exhaust can do more harm to your car.
