Summary
CLIENT SATISFACTION INITIATIVE 2G TELEMATICS HARDWARE REPLACEMENT This bulletin applies to vehcile equipped with navigation systems only. SERVICE INFORMATION On February 26, 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 to make a co-payment in order to receive the 3G hardware update. Please refer to the Claims Information below 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). You MUST use Service Comm to confirm bulletin Applicability. NOTE: - Vehicle eligibility will be viewed on the second page of Service Comm. This activity is not displayed on the main page of Service Comm because it is optional for customers to participate. - Vehicles without Navigation are ineligible as they are not equipped with TCUs. Retailer?s Responsibility It is the retailer?s responsibility to check SERVICE COMM using the appropriate Service Comm 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 vehicle subject to this client satisfaction activity was part of a retailer trade, the letter associated with that vehicle should be forwarded to the appropriate retailer for upgrade completion.
