Nissan filed this with NHTSA as a service bulletin dated Jan 21, 2025, received Jan 30, 2025, about the electrical system. It names 1 model year (2021). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 295 complaints with NHTSA since 2015. 62 of them name Electrical System — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
The contact owns a 2021 Nissan Rogue. The contact stated that while driving at an undisclosed speed, the instrument panel and radio went black. The driver’s and passenger’s side front doors and tailgate door failed to open intermittently. Additionally, the front and rearview camera failed to display intermittently.

Common questions
Source: NHTSA, 49 CFR 579.5Is Nissan NTB21-040B a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the NTB21-040B repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does NTB21-040B cover?
The manufacturer filed it against 1 model year: 2021 Nissan Rogue. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: built on or before 19 Oct 2021; built on or before 8 Mar 2021 — the build date is on the certification label in the driver’s door jamb.
