the customer before making any additional repairs. Failure to do so will result in claim review by your DPSM and
possible debit.
2012 Models: Complete the diagnosis procedure and if necessary, clean the pistons and replace the piston rings along

BACKGROUND
American Honda is announcing a powertrain warranty extension as a result of a settlement of a class action captioned,
Soto et al.v. American Honda Motor Co., Inc., Case No. 3:12-cv-1377-SI (N.D. Cal.).
The piston rings on certain cylinders may rotate and align, which can lead to spark plug fouling. This can set DTCs
P0301 No. 1 cylinder misfire detected, P0302 No. 2 cylinder misfire detected, P0303 No. 3 cylinder misfire detected,
P0304 No. 4 cylinder misfire detected, and cause the MIL to come on.
American Honda is extending the powertrain warranty to cover repairs related to engine misfire (that triggers DTCs
P0301 through P0304) to 8 years with unlimited mileage from the original date of purchase and has settled a class
action based on this remedial measure.
This warranty extension does 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.
