SERVICE BULLETIN
APPLICABILITY:

2012-16MY Impreza
2013-17MY Crosstrek
2014-18MY Forester

NUMBER: 04-27-21R

SUBJECT:

Electronic Power Steering (EPS) Gear Box
Assembly Warranty Extension

DATE: 07/27/21
REVISED: 07/28/21

INTRODUCTION:
As part of Subaru’s dedication to customer satisfaction, Subaru of America, Inc. (SOA) is announcing
an extension to the Basic New Car Limited Warranty for the Electronic Power Steering (EPS) Gear
Box Assembly for certain 2012-2018 MY vehicles. This will extend coverage under the Basic New
Car Limited Warranty on vehicles sold or leased in the United States.

In areas where there are high concentrations of road salt used to melt snow and ice, there is a
possibility corrosion may develop on the EPS Gear Box Assembly. If the vehicle were then to suffer
a significant enough impact from hitting a pothole or similar road hazard, it is possible the impact
could cause a portion of the EPS Gear Box housing to crack.

VERY IMPORTANT: It is very important to understand if this were to occur, there will NOT be a
complete loss of steering assist. Instead, it could result in an uneven steering feel when turning left or
right.
The EPS Gear Box Assembly Warranty Extension extends the original Basic New Car Limited
Warranty as it applies to the EPS Gear Box Assembly only when a crack in the gear box housing is
identified. The coverage period extends the vehicle’s Basic New Car Limited Warranty as it applies
to the EPS Gear Box Assembly to ten (10) years / unlimited mileage. Repairs performed during
this extended coverage period must be completed prior to the expiration of the ten year/ unlimited
mileage period.

CAUTION: VEHICLE SERVICING PERFORMED BY UNTRAINED PERSONS COULD
RESULT IN SERIOUS INJURY TO THOSE PERSONS OR TO OTHERS.
Subaru Service Bulletins are intended for use by professional technicians ONLY. They
are written to inform those technicians of conditions that may occur in some vehicles,
or to provide information that could assist in the proper servicing of the vehicle. Properly
trained technicians have the equipment, tools, safety instructions, and know-how to
do the job correctly and safely. If a condition is described, DO NOT assume that this
Service Bulletin applies to your vehicle, or that your vehicle will have that condition.

Subaru of America, Inc. is
ISO 14001 Compliant
ISO 14001 is the international standard for
excellence in Environmental Management
Systems. Please recycle or dispose of
automotive products in a manner that is friendly
to our environment and in accordance with all
local, state and federal laws and regulations.
