ing-U.S-12032535) - 2019 - crc - 6/25/18
4 New Vehicle Limited Warranty
Exclusions:Excluded from the
powertrain coverage are sensors,
wiring, connectors, engine radiator,
coolant hoses, coolant, and heater
core. Coverage on the engine
cooling system begins at the inlet to
the water pump and ends with the
thermostat housing and/or outlet
that attaches to the return hose.
Also excluded is the starter motor,
entire pressurized fuel system
(in-tank fuel pump, pressure lines,
fuel rail(s), regulator, injectors, and
return line) as well as the Engine/
Powertrain Control Module and/or
module programming.
Transmission/Transaxle Coverage
includes: All internally lubricated
parts, case, torque converter,
mounts, seals, and gaskets as well
as any electrical components
internal to the transmission/
transaxle. Also covered are any
actuators directly connected to the
transmission (slave cylinder, etc.). Exclusions:
Excluded from the
powertrain coverage are
transmission cooling lines, hoses,
radiator, sensors, wiring, and
electrical connectors. Also excluded
are the clutch and pressure plate as
well as any Transmission Control
Module and/or module
programming.
Transfer Case Coverage includes:
All internally lubricated parts, case,
mounts, seals, and gaskets as well
as any electrical components
internal to the transfer case. Also
covered are any actuators directly
connected to the transfer case as
well as encoder motor.
Exclusions: Excluded from the
powertrain coverage are transfer
case cooling lines, hoses, radiator,
sensors, wiring, and electrical
connectors as well as the transfer
case control module and/or module
programming. Drive Systems Coverage
includes:
All internally lubricated
parts, final drive housings, axle
shafts and bearings, constant
velocity joints, propeller shafts, and
universal joints. All mounts,
supports, seals, and gaskets as well
as any electrical components
internal to the drive axle. Also
covered are any actuators directly
connected to the drive axle (e.g.,
front differential actuator.).
Exclusions: Excluded from the
powertrain coverage are all wheel
bearings, drive wheel front and rear
hub bearings, locking hubs, drive
system cooling, lines, hoses,
radiator, sensors, wiring and
electrical connectors related to drive
systems as well as any drive system
control module and/or module
programming.

20 Emission Warranty Parts List
Emission-related defects in the
emission parts listed here are
covered under the Emission Control
System Warranty. The terms are
explained in theEmission Control
Systems Warranty 016 under
“Federal Emission Control System
Warranty” and the“California
Emission Control System Warranty.”
Important: Certain parts may be
covered beyond these warranties if
shown with asterisk(s) as follows:
. (*) 7 years/70,000 miles,
whichever comes first, California
Emission Control System
Warranty coverage.
. (**) 8 years/80,000 miles,
whichever comes first, Federal
Emission Control System
Warranty coverage for light duty
vehicles. (Also applies to
California certified light duty
vehicles.)
All listed parts 15 years/
150,000 miles, whichever comes
first, on California TZEV (NU6)
vehicles registered in a TZEV state
except Hybrid batteries and Hybrid A/C compressors, which are
covered for 10 years/150,000 miles,
whichever comes first.
