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.
CUSTOMER NOTIFICATION
Owners of affected vehicles were sent a class action settlement notice regarding this warranty extension starting in
October 2013.
Before doing work on a vehicle, verify its eligibility by doing an iN VIN status inquiry.
Refer customers seeking information about settlement benefits to www.enginemisfiresettlement.com, or instruct them to
call 888-888-3082.

WARRANTY CLAIM INFORMATION
PROCEDURE NOTICE: 2011 Models, confirm PCM software is or has been updated with the correct version
(Procedure A). Then piston cleaning, piston ring and spark plug replacement should be done (Procedure B).
Failure to follow this process correctly may result in a full debit of the warranty claim to your dealer.
2012–13 Models: Are equipped with updated software from the factory, no software update is needed. Piston
cleaning, piston ring replacement along with the spark plugs should be performed (Procedure B).
FLAT RATE NOTE: The procedure in this bulletin is different than the service manual. This procedure does not
require the complete removal of the power steering pump, catalytic converter(s), engine and transmission, or the
crankshaft. As a result, the operation number is unique and the FRT is reduced (Procedure B).
