Thanks for reaching out! In terms of how long a catalytic converter lasts, this essential component of your vehicle’s exhaust system should last 10 years or longer.
Catalytic converters help convert harmful emissions into harmless gas, and while the part should last 10 years or longer, it’s possible that it will get clogged, experience damage, or become contaminated by oil.
Below we’ve listed some common signs that indicate your catalytic converter may need replacing:
  • Foul odor, such as sulfur or rotten eggs
  • Reduced acceleration
  • Vehicle overheating
While these symptoms are indications that your catalytic converter may need to be replaced, the issue could have to do with another part of your exhaust system. It’s best to take your vehicle to an auto shop and have a mechanic diagnose the problem.
