Official summary
15810-03 - Special Coverage Revised. On some vehicles that are equipped with a 2.4L engine (RPO LAF), a malfunction-indicator light (MIL) may illuminate due to thermal damage or face erosion of the catalytic converter. This special coverage covers the condition described above for a period of 10 years or 120,000 miles (193,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership. Replace the catalytic converter.
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.
