What it saysHigh frequency noise with audio system display on this bulletin has been amended. NHTSA’s full summary ↓
Nissan filed this with NHTSA as a service bulletin dated Jan 29, 2024, received Feb 8, 2024, 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.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 133 complaints with NHTSA since 2015. 38 of them name Electrical System — the same broad component group this bulletin is filed under.

Common questions
Source: NHTSA, 49 CFR 579.5Is Nissan NTB21-067B 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 NTB21-067B 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 NTB21-067B cover?
The manufacturer filed it against 1 model year: 2021 Nissan Sentra. 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 after 17 Mar 2021 — the build date is on the certification label in the driver’s door jamb.
