Service bulletins
Technical service bulletins and other communications the manufacturer sent dealers about this vehicle. Ask a dealer for the full document by its number.
10252358This bulletin is a reminder to exercise caution when painting the Nexo, Fuel Cell Electric Vehicle (FCEV). During the painting processes, Volatile Organic Compounds (VOCs) may enter the fuel cell through openings or micro gaps in the intake or exhaust piping for the fuel cell. VOCs may damage certain components in the fuel cell causing reduced fuel-cell performance. VOC chemicals can harm the fuel cell system's performance. Precaution must be taken to seal openings for the fuel cell system before painting or placing Nexo in a curing oven.
10252357This bulletin provides a procedure to maintain the transmission in NEUTRAL such as pushing the vehicle without starting the fuel stack or when repairs require the transmission to be continuously maintained in NEUTRAL.
10251285This bulletin contains information about the proper removal of the windshield wiper blade protective cover on all models. If the protective cover is not removed correctly, there is a possibility of the rubber insert and rail spring becoming partially separated on the inner side of the wiper blade, which could lead to poor wiping performance and/or possible scratching of the windshield glass. Follow the procedure in this bulletin to properly remove the windshield wiper blade protective cover on all new wiper blades.

10235578Some NEXO (FE) vehicles may exhibit charging interruptions during hydrogen charging due to sensitive leak detection logic diagnostic conditions. This bulletin outlines the procedure to update the HMU controller software and replace the PRV (Pressure Relief Valve).
10235566Hyundai applies a Paint Protection Film (PPF) on new vehicles before delivery to dealerships. It provides a barrier between the paint and contaminants, such as rail dust, acid rain, and industrial fallout. In rare cases, the paint can become clouded under the PPF. These spots are the result of moisture trapped between the PPF and the paint.
10230904This bulletin provides information regarding condensation related to the accumulated moisture in the headlamp, rear combination lamp, daytime running lamp (DRL), or fog lamp. This TSB illustrates the various causes of condensation inside the lamp assembly. Lamp assembly replacement is NOT necessary in most cases. This condition can be eliminated by turning on the lamps with the engine running for several minutes or during normal driving operation.
