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.

If a dealer receives a supplemental Owner’s Manual addendum for a vehicle they have retailed, currently have in their new vehicle or pre-owned inventory, or a Nissan Rental Car (NRC), the dealer should either forward the owner’s manual addendum to the current owner or add the addendum to the Owner’s Manual in the glove box of any affected vehicle they currently control. 2. Customers receiving this Owner’s Manual addendum have been advised to place it inside the Owner’s Manual that came with their vehicle. ***** Release Schedule ***** Owner Notification Nissan will begin mailing the Owner’s Manual addendum to owners of all potentially affected vehicles beginning February 2023 via U.S. Mail. ***** Dealer’s Responsibility ***** It is the dealer’s responsibility to check Service Comm or DBS National Service History - Open Campaigns using the appropriate Campaign I.D. for the campaign status on each vehicle falling within the range of this voluntary service campaign, which for any reason, enters the service department. This includes vehicles purchased from private parties or presented by transient (tourist) owners and vehicles in dealer inventory.
