Infiniti bulletin AN23-005B
Infiniti filed this with NHTSA as a service bulletin dated Aug 15, 2024, received Sep 4, 2024, about the electrical system — 1 document under this number: ITB22-020B. It names 19 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.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationTELEMATICS CONTROL UNIT RESET AFTER AUTOMATIC COLLISION NOTIFICATION SERVICE INFORMATION The Telematics Control Unit (TCU) has the ability to send an automatic collision notification when the vehicle is involved in an accident. Once an automatic collision notification is performed, the function becomes disabled and the TCU must be reset to re-enable the automatic collision notification function. Some models will store DTC B2E1B-97 for “Automatic eCAll locked� as “CURRENT� when this function is disabled. This bulletin describes how to reset the TCU after an automatic collision notification has been performed. For models with B2E1B-97 for “Automatic eCAll locked� set as “CURRENT�, complete the SERVICE PROCEDURE starting on page 2, and then erase DTCs after confirming the TCU condition is “UNLOCK�.

Common questions
Source: NHTSA, 49 CFR 579.5Is Infiniti AN23-005B 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 AN23-005B 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 AN23-005B cover?
The manufacturer filed it against 19 model years: 2024 Infiniti Q50, 2023 Infiniti Q50, 2022 Infiniti Q50, 2021 Infiniti Q50, 2020 Infiniti Q50, 2022 Infiniti Q60 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
