Service bulletins for the 2015 Infiniti Q50

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

EXPIRATION NOTIF2021-01-08. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT. Expiration Notification - 2G Telematics Hardware Replacement Campaign Summary In 2016, INFINITI launched a Client Satisfaction Initiative (CSI) that provided clients with an opportunity to update the Telematics Control Unit (TCU) in vehicles equipped with a TCU designed to connect to the 2G cellular network. AT&T stopped accepting enrollments on the 2G cellular network, and discontinued its 2G cellular network coverage on December 31, 2016. Once the 2G cellular network was discontinued, there was no access to the INFINITI Connection features without a TCU hardware upgrade. Because AT&T will shut down its 3G network on December 31, 2021, INFINITI is discontinuing this Client Satisfaction Initiative to upgrade from 2G to 3G compatible hardware effective immediately. 3G services will continue to be provided until December 31, 2021. Vehicles equipped with a TCU that connects to the 3G cellular network will have no access to the INFINITI Connection features, including Emergency Calling and Automatic Collision Notification after that time. What Retailers Should Do Service Comm will deactivate PC451, PC452 and PC454 on any VINs on December 22, 2020. No further retailer action is required.

Infiniti USA Ret2018-12-03. Service bulletin. EQUIPMENT. Infiniti USA Electronic Field Communication Subject: Retailed Vehicle Open Campaign Report Lists Updated The lists for each retailer?s Retailed Vehicle Open Campaign Report has been updated today in DBS. We made our best effort to reassign vehicles to retailers based on the most recent owner information we received. The complexity of filtering out brokers (banks, salvage yards, and insurance companies) and reassigning VINs based on updated owner information affected over 123K records between INFINITI and Nissan, so we are unable to summarize the changes at a regional or retailer level. We suggest the retailers download their lists and have their outbound call centers compare information if necessary. If you have questions, please let us know. Additionally, we will have some enhancements coming in DBS effective November 17, 2018: Owner Data Updates (NNA side): 1. VIN, Campaign Code, and Source are the unique fields 2. Compare all fields except Remove Flag and Comments to see if there is a difference. a. If there is same VIN, Camp ID, and Source and all other fields are also the same then the record will be updated without changing Remove Flag and Comment field b. If there is same VIN, Camp ID, and Source and any other field is different, then the record will be inserted, in this case Remove Flag and Comment field will be blank as this is new record. The remove flag is being removed so the retailer will understand the information they previously flagged for removal has been updated and should be tried again before reapplying the removal flag. c. The retailer benefit of A & B above is duplicate records for the same VIN, Camp ID, and information source with the same customer contact information will no longer display in DBS on the Retailed Vehicle Open Campaign Report.
