Nissan filed this with NHTSA as a service bulletin dated May 21, 2024, received Jul 19, 2024, about the electrical system. It names 5 model years (2020–2024). 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 5 model years this bulletin names have filed 482 complaints with NHTSA since 2015. 125 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.
For the past 6 weeks my car has abruptly stopped. No forwarding, no lights. All of which occurred during heavily moving traffic putting myself and others in grave danger. Due to my quick thinking and CDL training I was able to redirect traffic until I was able to move to safety.

Common questions
Source: NHTSA, 49 CFR 579.5Is Nissan NTB20-055A 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 NTB20-055A 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 NTB20-055A cover?
The manufacturer filed it against 5 model years: 2024 Nissan Sentra, 2023 Nissan Sentra, 2022 Nissan Sentra, 2021 Nissan Sentra, 2020 Nissan Sentra. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
