How long do Subaru catalytic converters last?

How Long Do Subaru Catalytic Converters Last?
Subaru has employed multiple catalytic converters on its vehicles for many years, designing smaller converters and integrating them into the exhaust pipes, rather than employing a single, larger converter as most cars did at one time. The good news is that catalytic converters are free of moving parts and more or less maintenance-free. They should not require frequent replacement, if at all. According to agcoauto.com, catalytic converters are usually guaranteed for 80,000 miles, and on modern vehicles, the catalytic converter should last the life of the car, given an “average” life of about 100,000 miles. Additionally, it’s mentioned that catalytic converters last the life of the vehicle unless something abnormal compromises them, making Subaru converter failure extremely rare.
In summary, Subaru catalytic converters are designed to last the life of the vehicle, with an average lifespan of about 100,000 miles. While some owners have reported having to replace their catalytic converters, it’s important to note that such occurrences are considered very uncommon for Subaru vehicles.

Will a catalytic converter last 200000 miles?

The catalytic converter is supposed to last for the full lifetime of your vehicle. It rarely happens that someone must deal with dysfunctional catalytic converter but not impossible.

How often should catalytic converters be replaced?

around 10 years
A new catalytic converter should last for around 10 years but, as with most other vehicle components, the exact lifespan can differ. Mileage and engine tune can impact on the durability of the item, so it’s worth checking the condition after 50,000 miles.

How many miles can a catalytic converter last?

100,000 miles
Lifespan of a Catalytic Converter
Most catalytic converters eliminate more than 90% of an engine’s harmful emissions. If your vehicle is kept in good working order, it can function well for more than 100,000 miles and sometimes as long as the vehicle is running and driving.

How long do factory catalytic converters last?

10 years
On average, the factory-installed catalytic converter will last for 10 years, even if you drive well over 100,000 miles during that decade. Once the catalytic converter goes bad, however, you will have to replace it.
