BACKGROUND
Under certain circumstances, the vehicle may experience driveability issues, which may result in DTCs P0300 (random
misfire detected), P0301 (No. 1 cylinder misfire detected), P0302 (No. 2 cylinder misfire detected), P0303 (No. 3

To ensure customer confidence in our product, Honda
is extending the powertrain warranty from the original 5 years/
60,000 miles to 6 years with unlimited mileage from the original sale date. This warranty extension applies to any engine
components, such as camshafts, rocker arm assemblies, or spark plugs, requiring repair due to damage resulting from
those concerns identified in the first paragraph. The ECU and TCM software is covered under the vehicle's emissions
warranty beyond 6 years. Check iN for further details.
This warranty extension will not apply to any vehicle that has ever been declared a total loss or sold for salvage by a
financial institution or insurer, or has a branded or similar title under any state's law. This does not affect emission
warranties.
POSSIBLE CAUSE
Based on certain driving patterns and environmental factors, the DTC's stated above may set or whirling noise may
occur.
