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 IONIQ 5 N (NE EV N) vehicles are equipped with a Left Foot Braking (LFB) feature designed for use on performance roadways, such as racetracks. Technical Service Bulletin (TSB) 26-01-009H provides instructions to update the Vehicle Control Unit (VCU) software to retain the LFB feature or remove it based on the customer's preference. Regardless of whether the feature is retained or removed, this VCU update must be completed on all vehicles to ensure the proper ROM ID path for future VCU updates, and, in the case of LFB removal, a sticker must be applied in the owner's manual to indicate the vehicle is note equipped with the LFB feature. The customer's consent to retain or remove the feature must be documented following the process outlined in this bulletin prior to applying the VCU update to the vehicle.

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 9C6 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 9C6 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 9C6 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 – 10 Mar 2025 — the build date is on the certification label in the driver’s door jamb.
