Why Catalytic Converters Need Replacement

Over time, the catalytic converter can become clogged or damaged, leading to reduced engine performance, increased fuel consumption, and higher emissions.


Some common reasons a catalytic converter may need replacement in a 2018 Ford Expedition include:



  • Age and Mileage: Catalytic converters have a limited lifespan and may need to be replaced after 80,000 to 100,000 miles of use.

  • Mechanical Damage: The catalytic converter can be damaged by road debris, collisions, or other mechanical issues.

  • Contamination: Leaks in the engine or fuel system can cause the catalytic converter to become contaminated, reducing its effectiveness.


If you suspect your 2018 Ford Expedition's catalytic converter needs replacement, it's important to have it inspected by a qualified mechanic as soon as possible to avoid further damage to the vehicle's exhaust system.
