Official summary
Service bulletin - American Honda is extending the warranty coverage on the Piston Rings and Pistons for 2009-11 TSX L4 to 8 years from the original date of purchase or 125,000 miles, whichever comes first. Under certain specific circumstances the engine may create deposits on the oil control rings, which may lead to increased oil consumption.
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.
