What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationWhat it applies to, as the document itself states it — the build window in the manufacturer’s own words, read by machine from the PDF NHTSA serves. The build date is on the certification label in the driver’s door jamb; the dealer settles a borderline vehicle by its VIN.
Certain 2025MY IONIQ 5 N (NE N EV) vehicles’ Integrated Electronic Booster (IEB) software logic may disable the operation of the Electronic Brake Force Distribution (EBD) system when there is a malfunction with the steering angle, yaw sensor or lateral acceleration sensor and illuminate the ESC warning lamp in the instrument cluster, instead of the ABS and BRAKE warning lamps. Follow the procedures in this bulletin to update the IEB software to enable EBD operation when there is a malfunction with those sensors and display the ABS and BRAKE warning lamps.

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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Hyundai SERVICE CAMPAIGN 9B7 a recall?
No. A service campaign 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 SERVICE CAMPAIGN 9B7 repair free?
A service campaign is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does SERVICE CAMPAIGN 9B7 cover?
The manufacturer filed it against 1 model year: 2025 Hyundai Ioniq 5. 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 18 Dec 2023 – 18 Apr 2024 — the build date is on the certification label in the driver’s door jamb.
