Common symptoms reported by users include:

Low engine pickup / sluggish acceleration

Increased fuel consumption

Engine hesitation o r jerking

Strong smell of unburnt fuel o r rotten eggs

Check engine light CEL on the dashboard

These are classic signs of a partially o r fully blocked catalytic converter, especially if they develop gradually over time.
