INTRODUCTION:
Subaru of America, Inc. (Subaru) is recalling 2018 model year Legacy, Outback, and BRZ vehicles
equipped with a certain combination of head unit hardware and software, due to the possibility of
noncompliance with Federal Motor Vehicle Safety Standard (FMVSS) 111 – “Rear Visibility.”
AFFECTED VEHICLES:

Refer to Vehicle Coverage
Inquiry for WTZ-85 Recall
Applicability

Coverage for all affected vehicles must be confirmed by using the Vehicle Coverage Inquiry function
on subarunet.com. This information is now available.
DESCRIPTION OF THE ISSUE AND SAFETY RISK:
Due to a software issue, the head unit memory retrieval and assembly time may exceed the designed
time to begin the boot-up cycle. If this occurs, the head unit display will not boot, causing the
screen to remain blank. In this condition, while backing the vehicle, the rearview image may not be
displayed.
The failure to display the rearview image creates a noncompliance with the requirements of FMVSS
111 – “Rear Visibility,” increasing the risk of a crash.

DESCRIPTION OF THE REMEDY:
Subaru Retailers will reprogram the head unit software on affected vehicles at no charge to the
customer.
RETAILER RESPONSIBILITY:
Retailers are to promptly perform the applicable service procedures to correct all affected vehicles in
their inventory. Additionally, whenever a vehicle subject to this recall is taken into inventory or in for
service, necessary steps should be taken to ensure the recall correction has been made before selling
or releasing the vehicle.
Any vehicles listed in a recall/campaign that are in the Retailer’s stock must be:
•

Immediately identified.

•

Tagged or otherwise marked to prevent their delivery or use prior to inspection and/or repair.

•

Repaired in accordance with the repair procedures outlined in this Product Campaign
Bulletin.

Please be advised that it is a violation of Federal law for a dealer to deliver a new motor vehicle
covered by a recall under a sale or lease until the defect is remedied. Therefore, any Authorized
Subaru Retailer failing to perform the applicable service procedures to correct all affected vehicles
in their inventory prior to the vehicle being placed in service may be subject to civil penalties of up to
$6,000 per violation (i.e., for each vehicle), as provided in 49 CFR §578.6 and will also be in breach of
the Subaru Dealer Agreement.

OWNER NOTIFICATION:
Subaru will notify affected vehicle owners by first class mail, using internal Subaru owner records,
this month. Subaru is in the process of acquiring registration data and will notify owners again using
that data within the next 60 days. Retailers will be advised when owner renotification begins.
RETAILER AFFECTED VIN LISTS:
Each Subaru Retailer will receive an affected VIN list from their Zone Office. For the first
notification, Retailer assignment will be based on the selling retailer. For the second notification,
vehicles will be assigned to Retailers as follows:
•

Original vehicle owners are assigned to the original selling Retailer when their current
address is within a 100-mile radius of that Retailer.

•

If the original selling Retailer is inactive, the VIN has been assigned to the nearest active
Retailer.

•

For any new owners or when original owners live more than 100 miles from the original
selling Retailer, the VIN has been assigned to the nearest active Retailer.

IMPORTANT: Retailer affected VIN lists include information for vehicles affected by this recall.
This information will enable Retailers to follow up with owners of affected vehicles. The lists contain
owners’ names and phone numbers obtained from State Motor Vehicle Registration Records. The use
of such motor vehicle registration data for any other purpose is unlawful. Accordingly, Retailers are
required to limit the use of these lists for the sole purpose of completing this recall.

The following information addresses reprogramming file availability and a software update

update files from Subarunet (or using those sent directly from Nuspire) and transferring them
onto a flash drive for head unit installation. It is VERY IMPORTANT to read and understand this
information completely before proceeding.
This procedure and the related reprogramming files
apply to the following audio / navigation head unit:

NOTES:
•

The USB flash drives can be USB 2.0 or 3.0.

•

The USB flash drive MUST be reformatted to NTFS before loading any files to it. NTFS is
not the standard format on most USB flash drives.

•

The update files are not overly large but, during the reprogramming procedure, the head unit
backs up some files to the USB drive. For this reason, sufficient USB drive memory size is
required, especially for the High / Navigation units.

•

The flash drives should be dedicated to storing these reprogramming files only. Do NOT
use any flash drives which contains or requires the use of file management, encryption, file
backup or other software to function properly.

NOTE:
•

This new update also includes an enhancement to the map data for Subaru Retailer locations.

Step 1- Verify the currently installed Software Version ID using the following steps:
•

After starting the engine, from the HOME screen, touch “Settings”.

•

From the Settings > General screen, scroll down to and then touch “System Information”.
