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.

ITB11021B	2021-05-10. 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.

ITB15024	2021-05-10. Service bulletin. SERVICE INFORMATION After ECM reprogramming, the Calibration Verification Number (CVN) needs to be automatically calculated prior to State emissions testing (also known as Inspection Maintainence, I/M, or SMOG testing depending upon location). Allowing the vehicle to idle for 22 minutes will allow for faster CVN calculation. It is recommended that customers utilize this method if the vehicle needs to be tested for emissions soon after ECM reprogramming. See this bulletin for further detail.
ITB99043G	2021-05-10. Service bulletin. SERVICE INFORMATION NOTE - Failure to follow the procedures in this bulletin may result in the denial of a warranty claim. In an effort to protect the paint finish, Paint Guard Film (PGF) is applied on many new Infiniti vehicles. Paint Guard Film is a temporary white plastic protective film that is applied by the factory to the horizontal painted surfaces of the vehicle. The PGF protects the paint finish during vehicle handling, transportation and storage from harmful elements such as acid rain,iron particles, bird droppings, tree sap and other environmental contaminants. NOTE - Paint Guard Film CANNOT remain on the vehicle for more than six months after the vehicle's manufacture date. PGF must be removed at the end of six months. See this bulletin for further detail.
