What it saysCVT/TCM CALIBRATION DATA “WRITE” PROCEDURE This bulletin has been amended. NHTSA’s full summary ↓
Nissan filed this with NHTSA as a service bulletin dated May 8, 2023, received Jun 7, 2023, about the power train. It names 41 model years (2016–2022). 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 41 model years this bulletin names have filed 5,954 complaints with NHTSA since 2015. 1,149 of them name Power Train — 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 2016 Nissan Altima, the 132 owners who gave an odometer reading for Power Train reported it at a median of 67,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

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 NTB12-103H 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 NTB12-103H 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 NTB12-103H cover?
The manufacturer filed it against 41 model years: 2020 Nissan Altima, 2019 Nissan Altima, 2018 Nissan Altima, 2017 Nissan Altima, 2016 Nissan Altima, 2017 Nissan Juke and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
