Reviewed June 2026 from NHTSA manufacturer communication and service bulletin records. Carchieve is independent and not affiliated with any vehicle manufacturer or government agency.
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.
What this bulletin may mean before buying

Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
