Warranty Extension: 2018ꟷ19 Fit Carbon Buildup with Misfire DTCs
Dear FIRSTNAME LASTNAME:
What is the reason for this Warranty Extension?
On some 2018-2019 Fit vehicles, a combination of carbon deposits on the intake valves and the PGM-FI
software settings may lead to reduced combustion stability under certain circumstances. This results in a
misfire being detected and Malfunction Indicator Lamp (MIL) being illuminated.
American Honda is extending the warranty coverage for intake valve cleaning and software update due to
carbon buildup on the valves with misfire DTCs (P0300-P0304) on these vehicles to 10 years or 150,000
miles from the original date of purchase, whichever comes first.
What will HondaeBay logo do?
If your vehicle experiences a misfire and the MIL illuminates with misfire DTCs, call any authorized HondaeBay logo
dealer and make an appointment to have your vehicle inspected. If the dealer determines the misfire is
related to this condition, the intake valves will be cleaned, and the PGM-FI software will be updated for
FREE. Please plan to leave your vehicle at the dealer for at least half a day to allow them flexibility in
scheduling.
Lessor information

Extensión de garantía: Acumulación de carbono con códigos DTC de falla de encendido del Fit
2018ꟷ19
Estimado FIRSTNAME LASTNAME:
¿Cuál es el motivo de esta extensión de garantía?
En algunos vehículos Fit 2018-2019, una combinación de depósitos de carbono en las válvulas de
admisión y la configuración del programa PGM-FI puede reducir la estabilidad de la combustión en
determinadas circunstancias. Esto da como resultado que se detecte una falla de encendido y que se
ilumine la luz indicadora de fallas (MIL, por sus siglas en inglés).
American Honda está extendiendo la cobertura de la garantía para la limpieza de las válvulas de
admisión y la actualización del programa debido a la acumulación de carbono en las válvulas, con
códigos DTC de falla de encendido (P0300-P0304) en estos vehículos; la extensión de la cobertura será
a 10 años o 150.000 millas a partir de la fecha original de compra, lo que ocurra primero.
¿Qué hará Honda?
Si su vehículo experimenta una falla de encendido y la MIL se enciende con el código DTC de falla de
encendido, llame a cualquier concesionario Honda autorizado y programe una cita para que
inspeccionen su vehículo. Si el concesionario determina que la falla de encendido está relacionada con
esta condición, se limpiarán las válvulas de admisión y se actualizará el programa PGM-FI de forma
GRATUITA. Por favor haga planes para dejar su vehículo en el concesionario por lo menos medio día,
para permitir flexibilidad en la programación de la cita.
