NOTE: Make sure the software update has been completed, spark plugs replaced (Procedure A), and the
vehicle returned to the customer before making any additional repairs. Failure to do so will result in claim

2012 Models: Complete the diagnosis procedure and if necessary, clean the pistons and replace the pistons

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.

Is the PCM Program ID and/or Program P/N the same or newer than what is listed above, 2010–11 model years
only?
NO – The PCM software needs to be updated. Go to REPAIR PROCEDURE A.
YES – The correct software is installed. The piston rings on select cylinders need to be replaced. Go to step 4.
IMPORTANT NOTICE: The PCM software must first be updated with the correct version, replace spark plugs and
the vehicle returned to the customer. Piston cleaning and piston ring replacement, as described below, should
only be done after the customer has returned with a second failure or if the vehicle’s software is the correct
version. Failure to follow this process correctly may result in a full debit of the warranty claim to your
dealer.
4. Note which DTCs are stored in the vehicle.
Does the vehicle have DTC P0304 stored? (Any combination of DTCs P0301, P0302, P0303, P0304 may also be
stored.)
YES – Go to REPAIR PROCEDURE B for the cylinders listed, Cylinders 1–4: Clean the pistons, replace the
piston rings, and replace the spark plugs.
NO – Go to REPAIR PROCEDURE B for the cylinders listed below:

WARRANTY CLAIM INFORMATION
2010–11 Models: Confirm PCM software is or has been updated with the correct version, spark plugs 1–4 have
been replaced and the vehicle returned to the customer (Procedure A). Piston cleaning and piston ring
replacement should only be done after the customer has returned with a second failure or if the vehicles software is
the correct version (Procedure B). Failure to follow this process correctly may result in a debit of the
warranty claim to your dealer.
2012 Models: Are equipped with updated software from the factory, no software updated is needed. Piston

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).
