Bulletin Summary
TECHNICAL SERVICE BULLETIN: VOLUNTARY SERVICE CAMPAIGN: IEB INSPECTION AND WATER PROOFING OR IEB REPLACEMENT (SC321) - This bulletin provides the procedure to inspect the Integrated Electronic Booster (IEB) on certain 2019-2022MY Niro EV (DE EV) vehicles produced from December 5, 2018 through April 12, 2022, that were originally sold orare currently registered in one of the 28 states where heavy amounts of road salt are used. Over time, saltwater inflow into the Integrated IEB at the IEB fastening bolt hole may cause corrosion and lead to an inoperable IEB motor. Should this occur, the vehicle may experience illumination of the Anti-lock Brake System (ABS), Forward Collision-Avoidance Assist (FCA) warning lights, and/or a firmer brake pedal feel. The brakes remain operational. Kia is conducting this service campaign to improve corrosion resistance of the IEB assembly.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
