Official summary
Due to variations in production, certain exhaust manifold mounted catalytic converters may experience catalyst layer separation on affected vehicles. If this occurs, the MIL will illuminate with DTC P0421 or P0431, "Warm Up Catalyst Efficiency Below Threshold" stored in the PCM. Mitsubishi Motors North America, Inc. is extending the catalytic converter warranty only on affected vehicles currently registered in certain states from 8 years / 80,000 miles to 10 years / 120,000 miles.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
