Nissan filed this with NHTSA as a service bulletin dated Feb 19, 2025, received Feb 25, 2025, about the power train. It names 14 model years (2016–2024). 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.

What owners reported
Source: NHTSA complaint databaseOwners of the 13 model years this bulletin names have filed 653 complaints with NHTSA since 2015. 153 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 Titan XD, the 17 owners who gave an odometer reading for Power Train reported it at a median of 16,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

I have noticed this problem a few times, specifically in highway traffic. When getting back up to speed, i have noticed my 2022 Nissan Titan suddenly jerk as I am accelerating back up to the posted speed limit. This has happened a few times. First time I did not pay it to much consideration, but now it's something that worries me.

The automatic transmission in my 2024 Nissan Titan PRO-4X intermittently malfunctions when slowing to a stop. As the vehicle decelerates to about 1–2 mph, there is a distinct “bump” or “lurch” as if the truck has been lightly rear-ended. The sensation occurs most often at traffic lights or rolling stops.

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 NTB23-023B 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 NTB23-023B 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 NTB23-023B cover?
The manufacturer filed it against 14 model years: 2024 Nissan Titan, 2023 Nissan Titan, 2022 Nissan Titan, 2021 Nissan Titan, 2020 Nissan Titan, 2019 Nissan Titan and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
