***** Client Satisfaction Initiative Summary *****
On February 26th, 2016 Infiniti announced that it was sending a reminder notification to clients
affected by AT&T’s planned discontinuation of the 2G cellular network. In June 2016, Infiniti
communicated instructions to retailers to update new vehicles in their inventory with 3G
compatible telematics control units.
At this time, Infiniti is beginning the process of making 3G compatible hardware available to
owners of affected vehicles as identified above. This upgrade may require an owner make a
co-payment in order to receive the 3G hardware update. Please refer to the chart provided on
page 2 to determine if an owner co-pay is required. This client satisfaction initiative includes
both the hardware upgrade and a complimentary one-year subscription to Infiniti Connection
Plus telematics service; this does not apply to PC454 (see page 2 for details).
Note: Vehicle eligibility will be viewed on the second page of Service Comm (except PC454).
This activity is not displayed on the main page of Service Comm because it is optional for
clients to participate.

***** What Retailers Should Do *****
1. Verify if vehicles are affected by this client satisfaction initiative using Service Comm I.D.
PC451, PC452, which can be found on the second page, or PC454 on the main page.
2. Retailers should ensure clients are informed of this 3G upgrade option when bringing their
vehicle in for service and that clients understand a co-pay may be involved.
3. Retailers must obtain client approval in advance of the upgrade being performed. If client
approves, update the vehicle using the procedure included with this announcement.

***** Retailer’s Responsibility *****
It is the retailer’s responsibility to check SERVICE COMM using the appropriate Campaign
I.D. for the status on each vehicle falling within the range of this client satisfaction initiative
which for any reason enters the service department. If a VIN subject to this client
satisfaction activity was part of a retailer trade, the letter associated with that VIN should
be forwarded to the appropriate retailer for upgrade completion.
Frequently Asked Questions (FAQ):
Q.
What is the reason for this client satisfaction activity?
A.
AT&T will discontinue its 2G cellular network coverage on December 31, 2016. Like
all cellular-equipped devices designed to connect to the 2G cellular network, 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 stopped accepting new
enrollments on the 2G network on July 1, 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 “2nd Generation” digital cellular telephone technology; it is the name of a
specific network that mobile telephone equipment uses to provide connectivity.
PC451, PC452, PC454 | Original Document
Q.
Which vehicles have 2G compatible TCUs?
A.
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:
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:
Will the new TCU hardware work with the 4G cellular network?
A:
No. 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.
However, Infiniti has no control over availability of any cellular network.
Q:
How much will the replacement TCU cost?
A.
Clients are asked to participate in the cost of the parts and labor to upgrade the TCU.
The client co-pay amount varies by model year and is listed in the chart below.
Infiniti will cover the balance of the upgrade cost and include a complimentary oneyear subscription to Infiniti Connection Plus telematics services (PC451 & PC452
only). PC454 will receive a complimentary 6-month trial to Infiniti Connection Plus
telematics services. The Infiniti Connection Plus telematics services subscription
retail cost is $308/year.

Q.
Why are Q50 vehicles currently excluded from this client satisfaction
initiative?
A.
Infiniti is still preparing the upgrade specific to the Q50. A separate announcement
will be made when Q50 upgrade is available.
Q:
A client has a 2G-equipped Infiniti and is enrolled in Infiniti Connection™.
Why do they have to pay for a replacement TCU?
A:
The discontinuation of the 2G cellular network is outside of Infiniti’s control. The
Infiniti Connection™ subscription agreement states that clients are responsible for
any hardware upgrades due to changes in telecommunication systems. However,
Infiniti is including a complimentary one-year subscription to Infiniti Connection Plus
telematics service when an owner elects to upgrade to a 3G compatible TCU. A one
year subscription to Infiniti Connection Plus telematics service is currently valued at
$308/year, which is more than the owner co-pay for this client satisfaction initiative.
The one year subscription will be added to any remaining time currently on an
owner’s trial enrollment. If the client already has a paid subscription on their 2G
equipped vehicle, the current subscription will be cancelled and a pro-rated refund
will be sent to the owner after the new 3G compatible TCU upgrade is completed.
Q:
Will the SOS button in the vehicle still work?
A:
If an owner of an affected vehicle enrolled in an Infiniti Connection service trial or
subscription prior to June 30, 2016, then the SOS button in the vehicle will work
through the service trial or subscription period as long as the vehicle’s telematics
hardware is connected to the cellular network. If an owner of an affected vehicle did
not enroll in an Infiniti Connection™ service trial or subscription prior to July 1,
2016, then the SOS button in the vehicle will not function until the TCU is 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.
Q.
What will be the service department action?
A.
If an owner elects to upgrade to a 3G compatible TCU and agrees to pay the
applicable co-pay, the retailer’s service department should install the 3G hardware
using the procedure accompanying this announcement.
Q.
How long will the upgrade take?
A.
The upgrade will typically take under 2 hours to complete.
PC451, PC452, PC454 | Original Document
Q.
When will vehicle owners be notified?
A.
Infiniti plans to begin notifying owners of potentially affected vehicles in September,
2016 via U.S. Mail. Owners may contact Infiniti Owner Services at 855-444-7244 to
verify if their vehicle is affected by this issue.
Q.
Are parts readily available?
A.
Yes. Parts will be automatically shipped to retailers and are expected to arrive
beginning September 6th, 2016. Retailers can order additional parts as needed once
they receive their automatic shipment.
Q.
Will a courtesy vehicle be provided while the retailer is servicing the
vehicle?
A.
Infiniti may provide a courtesy vehicle for the client to use while their vehicle is
being serviced. Courtesy vehicles are subject to availability and not guaranteed.
Please check with your retailer for availability and further details.
Q.
Will I have to take my vehicle back to the selling retailer to have this service
performed?
A.
No, any authorized Infiniti retailer is able to perform this service.
For Consumer Affairs: Please inform us of the retailer where you would like to
have the upgrade completed.
Q.
Does this issue affect any other Infiniti (or Nissan) models?
A.
Model year 2011-2015 Nissan LEAF vehicles are also affected.
Q.
I did not receive a letter. How can I tell if my vehicle is affected?
A.
Please provide your vehicle identification number (VIN) to the retailer so that the
retailer can check if your vehicle is included in this campaign. Clients may also
contact Infiniti Owner Services at 855-444-7244 to verify if their vehicle is affected
by this issue.

Retailer Service Questions:
Q.
Is it possible to identify if a vehicle has a 2G or 3G TCU without removing
the TCU?
A.
For the QX60, Q70, QX80:
To identify if the vehicle has a 2G or a 3G TCU, complete the following steps on the
head unit:
1. Press the hard button labeled Setting/Info
2. Press the “Others” soft button on the center display screen
3. Press the “Infiniti Connection” soft button
4. Press “Unit ID information”
5. If TCUID starts with “ 2021-1” it is a 3G device
6. If TCUID starts with “ 2021-0” it is a 2G device
Q.
What if the 2G or 3G TCU part is missing the IMEI (International Mobile
Equipment Identity) number that is used to identify the TCU?
A.
The IMEI number can be found on the label adhered to the TCU part. If this label is
missing or is not legible, you can use the SIM ID/ICCID instead. The SIM ID/ICCID is
located on the head unit “Unit ID” screen, you can locate this screen by following the
steps in the question above. You will need to locate this number prior to calling the
SiriusXM agent to deactivate the 2G TCU and activate the 3G TCU.
Retailers will also need to have the model, model year, sales country (i.e. USA),
marketing color name of the vehicle and VIN available
Q.
Who can I call with Telematics system specific questions?
A.
Contact the Infiniti Connection / Infiniti InTouch Services call center @ 855-4447244. The call center is operational between 8AM-12AM EST Monday through
Saturday.
Q.
Can the 283B0-3JA5A part number be used on all Infiniti models?
A.
The 283B0-3JA5A part number can only be used on:
 2013 Infiniti M37/M56, JX35 and QX56
 2014-2016 Infiniti Q70, QX60 and QX80
Q.
May a retailer offer retailer paid goodwill to cover the cost of a client’s copay for this upgrade?
A.
The retailer is responsible for collecting the copay from an owner electing to upgrade
to a 3G compatible TCU and may choose to not collect co-pays as service to their
clients. Infiniti will debit a retailers non-vehicle account for each claim submitted
when a co-pay applies.
Q.
Will Infiniti cover an owner’s co-pay using factory goodwill?
A.
No. Factory goodwill will not cover a co-pay for owner’s electing to upgrade to a 3G
compatible TCU.
