Nissan filed this with NHTSA as a service bulletin dated May 21, 2024, received Jul 19, 2024, about the electrical system. It names 41 model years (2017–2024). 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.

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.

What owners reported
Source: NHTSA complaint databaseOwners of the 40 model years this bulletin names have filed 2,247 complaints with NHTSA since 2015. 338 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 2017 Nissan Pathfinder, the 19 owners who gave an odometer reading for Electrical System reported it at a median of 45,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
I currently have a 2023 Nissan Titan Pro-4X 4WD that intermittently when slowing to a stop between the speeds of 0-7mph it will, at times, feel as though the transmission is dropping from 3rd gear to 1st gear without cycling into 2nd gear properly creating almost a bumping effect to where it feels like you are almost being bumped from…

My 2019 Nissan Maxima (approximately 70,000 miles) displayed a hazard warning indicating a vehicle failure and began stalling without warning. The vehicle was brought to Mossy Nissan on May 28, 2025, where it has remained for over 11 days. The dealership has been unable to identify or repair the root cause of the electrical failure.

Since the start of 2018 I have had my car shut off while driving. I have taken it multiple dealerships to help solve this issue. Every time they came back and said that they could not duplicate the problem and nothing could do for me. I have reached out to the manufacture they also said the same thing they could not do anything.

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 NTB17-127C 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 NTB17-127C 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 NTB17-127C cover?
The manufacturer filed it against 41 model years: 2018 Nissan Altima, 2017 Nissan Altima, 2024 Nissan Frontier, 2023 Nissan Frontier, 2022 Nissan Frontier, 2021 Nissan Frontier and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
