Service bulletins for the 2021 Nissan Sentra

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.

Due to a new electrical architecture, the vehicle mileage is now stored in multiple control modules. When a mileage difference is detected between modules, the module with the lower value will be immediately overwritten, replacing it with the higher mileage. If a new combination meter module is installed, it will automatically be overwritten to the correct vehicle mileage.
