Yes. Karvaan owners have reported:

Engine sluggishness, poor acceleration, and check engine lights.

Catalytic converter clogging due to:

Unburnt fuel deposits

Low-quality fuel

Delayed oil changes and lack of engine tuning

⛔ Conclusion: Clogged o r damaged catalytic converters reduce power and increase emissions. Regular maintenance is critical.
