Quick answer

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 customers 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 owners manual to indicate the vehicle is not equipped with the LFB feature. The customers 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

Treat this as service research, not a verdict on one car. 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.
