Service campaign 26-01-009H TSB
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
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. This bulletin 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 not 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.
