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 6 model years this bulletin names have filed 1,608 complaints with NHTSA since 2015. 128 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.
On the 2017 Nissan Rogue, the 36 owners who gave an odometer reading for Engine reported it at a median of 25,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
When driving home on the evening of 3/24, I was on the interstate (70mph) when my 2021 Nissan Rogue started to decelerate and would not gain speed. I got off at the next frontage road exit and when at the stop sign my check engine light came on and shortly after my car started sputtering when stopped and would barely gain speed.

Common questions
Source: NHTSA, 49 CFR 579.5Is Nissan NTB23-083 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 NTB23-083 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 NTB23-083 cover?
The manufacturer filed it against 6 model years: 2018 Nissan Rogue, 2017 Nissan Rogue, 2022 Nissan Rogue Sport, 2021 Nissan Rogue Sport, 2020 Nissan Rogue Sport, 2019 Nissan Rogue Sport. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
