Nissan filed this with NHTSA as a service bulletin dated May 11, 2024, received Jul 19, 2024, about the electrical system. It names 7 model years (2019–2025). 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.

Read by machine from the document NHTSA serves (5 pages), read Sep 30, 2026. A part number is shown only where it matches Nissan’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.

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 7 model years this bulletin names have filed 616 complaints with NHTSA since 2015. 407 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.
On the 2019 Nissan Leaf, the 15 owners who gave an odometer reading for Electrical System reported it at a median of 90,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The latest recall, NHTSA Recall 25v-655 for which there is no fix, has rendered my vehicle useless for any round-trip of more than approximately 130 miles from home. This is the same issue for which there was a recall for 2019/2020 LEAFs and after a year there was no known fix from the manufacturer

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Nissan NTB23-024A 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 NTB23-024A 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 NTB23-024A cover?
The manufacturer filed it against 7 model years: 2025 Nissan Leaf, 2024 Nissan Leaf, 2023 Nissan Leaf, 2022 Nissan Leaf, 2021 Nissan Leaf, 2020 Nissan Leaf and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
