Warranty Extension: MIL Comes On With DTCs P0301 Through P0304
(Supersedes 13-080, dated July 24, 2014, to revise the information marked by the black bars)
REVISION SUMMARY
• The layout was changed to one column for pages 1 through 3.
• The FRT was changed for replacing rings on cylinder No. 4.
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 through P0304 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.
CORRECTIVE ACTION
Inspect the vehicle and, if necessary, clean the pistons, and replace the piston rings in the affected cylinders.
