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 2 model years this bulletin names have filed 239 complaints with NHTSA since 2015. 34 of them name Engine — 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.
Dear NHTSA, I would like to report a safety issue while driving this vehicle on Interstate 35E North of downtown St Paul, MN. While driving in traffic I went to move into a lane to the right allowing us to move in a less congested lane of traffic.
2023 Nissan Pathfinder · Engine · filed with NHTSA Sep 12, 2023
Transmission cannot go into neutral unless the engine is running... but what if car runs out of gas and the engine cannot run? Car ran out of gas and transmission could not go into neutral to be pushed out of the road. Very dangerous situation
2022 Nissan Pathfinder · Engine · filed with NHTSA May 28, 2022
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 NTB24-016 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 NTB24-016 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 NTB24-016 cover?
The manufacturer filed it against 2 model years: 2023 Nissan Pathfinder, 2022 Nissan Pathfinder. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: built on or before 17 Oct 2022 — the build date is on the certification label in the driver’s door jamb.
