Suppose that a car has 120,000 miles on it and the catalytic converter fails. From what I read (see here as an example), age doesn't appear to be a general cause for failure. Is this a possibility if a car is old?

Note the site lists the following reasons:

  • Thermal Failures
  • Contamination
  • Coated or Fouled
  • Other in pictures: Melted Brick: Engine running too hot, Burned Converter: Exhaust temperatures too high, Oil-Fouled Brick: Engine oil entering exhaust, Plugged Brick: Incomplete combustion by-products, Road Damage: Impact under vehicle crushing converter.

I found this; it indicates they last about 100,000 miles.
