Official summary
15810-02 - Special Coverage (revised warranty section). 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. The repairs will be made at no charge to the customer.
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.
