*****Retailer Announcement*****
On February 26th, Infiniti announced that it was sending a reminder notification to clients
affected by AT&T’s planned discontinuation of the 2G cellular network. In late summer 2016,
Infiniti plans to provide further information to affected clients regarding options to have
their telematics units updated.
At this time, Infiniti is conducting a retailer inventory service action on affected units in
retailer inventory to replace the 2G-compatible telematics control unit with a telematics
control unit designed to connect to the AT&T 3G cellular network. The affected vehicles are
either currently in retailer inventory or assigned and in transit to the retailer. Infiniti
requests these vehicles be updated prior to sale to enable clients to access available Infiniti
Connection™ features, including Automatic Collision Notification and Emergency Calling.
There are approximately 142 Q50 vehicles in retailer inventory that are equipped with
telematics control units designed to connect to the 2G cellular network. However, the
hardware upgrade service procedure is not available at this time. Please do not take any
action at this time on Q50 vehicles that are equipped with a 2G-compatible telematics
control unit. Further instructions will be provided at a later date for the TCU Upgrade on
affected Q50 vehicles. Infiniti expects this communication to occur in late summer 2016.
IMPORTANT: Retailers should not sell or trade any affected vehicles in retailer
inventory subject to this service action until the 3G-compatible Telematics Control
Unit has been installed.
*****What Retailers Should Do*****
PLEASE FOLLOW THE ATTACHED SERVICE PROCEDURE INSTRUCTIONS:
1. Verify if vehicles currently in retailer inventory are affected by this inventory service
action using Service Comm I.D. PC454.
2. Use the attached procedures to replace and activate the Telematics Control Unit for
vehicles identified in Service Comm. Part number (283B0-3JA5A) was automatically
sent to each retailer beginning June 24, 2016. Retailers should use these parts to
complete the inventory service action.
3. The service department should submit the applicable warranty claim for the action
performed so it can be closed on Service Comm.
***** Retailer Responsibility *****
It is the retailer’s responsibility to check Service Comm using the appropriate campaign I.D
for the service action status on each affected vehicle currently in inventory.
Frequently Asked Questions (FAQ):
Q.
Will there be a campaign for vehicles that have already been retailed?
A.
Additional information regarding options for retail clients will be the subject of a
future announcement. Infiniti will communicate this information as soon as hardware
is readily available.
Infiniti will contact affected clients directly; clients may contact Infiniti Owner
Services at 855-444-7244 to verify if their vehicle is affected by this issue.

The following models equipped with navigation have 2G-compatible TCUs:
 2013 Infiniti M37/M56, JX35 and QX56
 2014-15 Infiniti Q50
 2014-15 and some 2016 Infiniti Q70, QX60 and QX80
Q.
Why are Q50 vehicles currently in retailer inventory being excluded from
this retailer service action?
A.
The parts currently available are not fully compatible with the vehicle’s Infiniti
InTouch™ System. Infiniti will activate the retailer inventory action for affected Q50
vehicles when appropriate parts are available to provide the best experience for our
clients. Infiniti expects this communication to occur in late summer 2016.
Q.
Are Infiniti Courtesy Vehicles eligible for this activity?
A:
Infiniti Courtesy Vehicles are retailed vehicles and will be addressed as part of a
future announcement. Infiniti will communicate this information as soon as hardware
is readily available. If a courtesy vehicle was recently activated and is identified in
Service Comm with I.D. PC454, retailers may complete this procedure.
Q.
AT&T has announced plans to discontinue its 2G cellular network coverage
on December 31, 2016. How does this affect an Infiniti client’s access to
Infiniti Connection™?
A:
Like all cellular-equipped devices designed to connect to a cellular network on the 2G
access band, Infiniti models with a 2G-compatible telematics control unit (TCU) will
be unable to use or receive services from that device after December 31, 2016.
Without an upgrade to the TCU, Infiniti Connection™ features will not be available
after that time and may be impacted prior to that date depending upon AT&T’s
proprietary decisions regarding discontinuing 2G network coverage. Also, AT&T will
not accept new enrollments on the 2G network after June 30, 2016. If an affected
vehicle has not had a hardware upgrade and was not enrolled in Infiniti Connection™
before June 30, 2016, then it will not have access to the available Infiniti
Connection™ features, including Emergency Calling and Automatic Collision
Notification, until the upgraded hardware is installed.
Q:
What is 2G cellular network access?
A:
2G refers to digital cellular telephone technology; it is the name of a specific network
that mobile telephone equipment uses to provide connectivity.
Q:
Will the new TCU hardware work with the 4G cellular network?
A:
The new TCU hardware is designed to connect to the current AT&T 3G cellular
network technology.
Q.
Why is Infiniti using 3G technology rather than 4G?
A.
Infiniti has studied how to integrate newer technology into your vehicle and
developed solutions aimed at delivering a hardware update option with the least
inconvenience to clients. The 3G network is supported throughout the U.S. by AT&T
and is expected to continue for years to come. However, Infiniti has no control over
availability of any cellular network.
Q:
How much will the replacement TCU cost?
A:
Pricing of the replacement TCU is not yet available. Infiniti plans to communicate the
options for equipment upgrades for affected clients wishing to renew or subscribe to
the Infiniti Connection™ telematics program once the hardware is readily available.
Q:
Why must I enroll in the Infiniti Connection™ trial before June 30, 2016?
A:
AT&T will not accept new enrollments on the 2G network after June 30, 2016. If a
vehicle with 2G equipment is purchased prior to June 30, 2016, they should be
enrolled in Infiniti Connection™ on or prior to that date to help ensure the enrollment
is able to be processed.
Q:
What happens if I do not replace the TCU?
A:
Once the 2G cellular network is discontinued, the TCU will no longer be able to
access the Infiniti Connection™ features, including Emergency Calling and Automatic
Collision Notification, without a hardware upgrade. New vehicles sold after June 30,
2016 will not be able to be enrolled in the complimentary trial for Infiniti
Connection™ until the hardware has been upgraded to be compatible with the 3G
cellular network.
Q:
A client has a 2G-equipped Infiniti and is enrolled in Infiniti Connection™.
Will they have to pay for a replacement TCU?
A:
The discontinuation of the 2G cellular network is outside of Infiniti’s control and the
Infiniti Connection™ subscription agreement makes clear that clients are responsible
for any hardware upgrades due to changes in telecommunication systems. However,
Infiniti plans to offer support to affected clients with vehicles equipped with 2G
compatible TCU hardware and who are renewing or subscribing to Infiniti
Connection™. Clients with vehicles equipped with 2G compatible TCU hardware will
be asked to contribute to the cost of the hardware upgrade. Additional details will be
provided to clients once parts are readily available.
Q:
A client has a 2G-equipped Infiniti but is not enrolled in Infiniti
Connection™. Will I have to pay for the replacement TCU?
A:
For Infiniti clients choosing to subscribe to Infiniti Connection™, Infiniti plans to offer
support to those clients wishing to upgrade the TCU hardware. Additional details will
be provided to clients once parts are readily available.
Q:
How soon can we expect more information regarding pricing and hardware
availability?
A:
Parts availability, pricing and other details are in the process of being finalized and
we expect to be able to provide additional information in a notification to affected
clients beginning in late summer 2016.
Q:
Will the SOS button in the vehicle still work?
A:
If an owner of an affected vehicle is not enrolled in an Infiniti Connection™ service
trial or subscription prior to June 30, 2016, then the SOS button in the vehicle will
not work and will be unable to function until the TCU has been upgraded.
Q:
Will my vehicle's navigation system feature be affected by the
discontinuation of the 2G cellular network?
A:
No. If your vehicle is equipped with an Infiniti Navigation system, the navigation
system is unaffected by the discontinuation of AT&T's 2G cellular network.
