A catalytic converter can potentially last the entire lifespan of your vehicle, or it can go bad in as little as 20,000 miles. Several factors can contribute to how quickly a catalytic converter may go bad, including exposure to water and prolonged periods of idling at low RPMs.
The combination of emissions-causing contaminants and the extreme heat that the converter operates under can eventually cause the converter to fail. In some cases, wear and tear on the converter due to physical damage may also lead to decreased performance or complete failure.
Furthermore, leaded fuel, a less-common type, also causes wear and tear on catalytic converters and causes them to fail sooner than new, unleaded fuel. Keeping track of your vehicle’s service history, ensuring that any and all repair work is properly done, and making sure to use only unleaded fuel are the best preventive measures to ensure that your catalytic converter does not go bad prematurely.
What are the 3 most leading failures of a catalytic converter?
The three most common failures of a catalytic converter are clogging, mechanical damage and overheating. Clogging occurs when tiny particles accumulate on the converter substrate and impede proper exhaust flow.
This typically happens due to oil or fuel contamination, though other contaminants such as carbon, soot, silicones, plastics or other foreign substances in the exhaust flow may also be a factor. Mechanical damage is often due to weakened converter bodies or broken hanger brackets.
Overheating of the catalytic converter can happen due to a malfunctioning engine, incorrect driving habits, a clogged catalytic converter, an aftermarket exhaust system, or driving in a very dusty environment.
Overheating can cause rapid deterioration of the converter, eventually leading to failure.
What happens if you drive with a bad catalytic converter?
Driving with a bad catalytic converter is dangerous and can cause serious damage to your vehicle. The catalytic converter is an important emission control device that converts toxic pollutants into less harmful emissions before they are released into the environment.
