Has your car displayed symptoms of a rattling noise from the exhaust, possibly due to a broken o r loose catalytic converter element?

A damaged o r broken internal ceramic honeycomb inside the converter can rattle. Have you heard metallic sounds from beneath the car while driving?

Yes, rattling noises under the car, especially on cold starts o r rough roads, were reported. Mechanics diagnosed these sounds as loose ceramic honeycomb pieces inside the catalytic converter, a clear sign of internal damage.
