Infiniti filed this with NHTSA as a service bulletin dated Feb 27, 2025, received Mar 8, 2025, about the electrical system. It names 1 model year (2025). 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 communicationECM REPLACEMENT PROCEDURE REQUIRED FOR RES EQUIPPED VEHICLES SERVICE INFORMATION If any of the APPLIED VEHICLES equipped with Remote Engine Start (RES) requires Engine Control Module (ECM) replacement, the Body Control Module (BCM) must be replaced also at the same time. If you are not familiar with the Re/programming, Configuration procedure, refer to the Electronic Service Manual (ESM) and the CONSULT Operation Manual to reprogram the Electronic Control Unit (ECU). Follow all precautions in both manuals to prevent possible personal injury or death and/or damage to the ECU. This procedure will go back and forth between the ECM and BCM steps as found in the ESM. Damage will occur requiring the ECM and the BCM to be replaced a second time if the following SERVICE PROCEDURE is not followed. Perform the following steps from the Electronic Service Manual (ESM) in this order: A. Perform “Work Procedure (Before Replacing ECM)” to save the ECM data. B. Remove the ECM. C. Remove the BCM. D. Install the new BCM and then perform “Additional Service When Replacing BCM - Work Procedure” up to and including “Register of Vehicle Identification Number”. E. Install the new ECM and then perform “Additional Service When Replacing ECM - Work Procedure (After Replacing ECM)” up to and including “Writing MAC Key for ECM”. F.

What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 8 complaints with NHTSA since 2015. 2 of them name Electrical System — 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.
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 Infiniti ITB25-003 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 ITB25-003 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 ITB25-003 cover?
The manufacturer filed it against 1 model year: 2025 Infiniti QX80. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
