Why is my BMW i4 making a loud rattling noise?

I recently purchased a BMW i4 and have been noticing a loud rattling noise coming from the engine. It seems to happen when I start the car and randomly throughout my drive. What could be causing this and how can I fix it?

The cause of the rattling noise could be due to loose components in the engine or exhaust system. It is important to have this checked by a certified mechanic as soon as possible to prevent any further damage or potential safety hazards.

Another possibility is that the rattling noise could be caused by worn out or damaged belts. It is recommended to have all belts inspected and replaced if necessary to ensure optimal performance of your BMW i4.

In some cases, the rattling noise could be a sign of a failing catalytic converter. This is a crucial component for reducing emissions and if left untreated, it could lead to costly repairs down the line. It is best to have this checked by a professional mechanic.
