Nissan filed this with NHTSA as a service bulletin dated Sep 4, 2024, received Sep 10, 2024, about the engine — 1 document under this number: NTB24-045. It names 5 model years (2020–2024). 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Nissan JD01A 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 JD01A 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 JD01A cover?
The manufacturer filed it against 5 model years: 2024 Nissan Sentra, 2023 Nissan Sentra, 2022 Nissan Sentra, 2021 Nissan Sentra, 2020 Nissan Sentra. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
