Service bulletin PC454

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.

NHTSA's summary

"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."

ITB11021B2021-05-10. Service bulletin. SERVICE INFORMATION Temporary tire Flat Spotting is common on New Dealer In-Stock vehicles that have not been occasionally moved. Flat Spotting can occur after the vehicle has been parked (not moved) for a few days, or longer. In most cases it is temporary. In extreme cases it can be permanent. Vehicles should be moved every 30 days, in one direction only, enough to rotate the tires 90° (see Figure 1). Moving vehicles as shown in this bulletin will prevent tire Flat Spotting. See this bulletin for further detail.
