Wife got a check wallet light today in her Versa, scanned it and got the dreaded P0420. She's still got 3 years before her first required smog check, but the car only has 110k miles on it, has never had a misfire, and doesn't burn a significant amount of oil (1 qt in 5k miles max).
Is this all we can expect out of cats these days? My Camry still has the original cat at 170k despite being one of those oil-drinking 2AZ-FEs, to the point that it made visible smoke before I replaced the engine. Her old Cavalier made it to almost 250k on the original cat.
I've had to replace them on the Mustang and XTerra, but both were due to misfires.
