Are catalytic converter problems more common in high-mileage Changan Karvaan vehicles?

Is there a certain mileage range e.g. after 50,000 km when Karvaan catalytic converters usually start causing trouble? Let’s hear from owners who’ve crossed major mileage milestones.

Yes, issues typically begin after 50,000–70,000 km, especially if:

Poor-quality fuel is used

Maintenance is neglected

Frequent city driving with short distances

Some users have even reported problems earlier, around 30,000 km, in areas with extremely dusty conditions o r poor fuel. High mileage accelerates wear, especially if engine combustion isn’t efficient.
