Bulletin Summary
TECHNICAL SERVICE BULLETIN: EWP COOLANT HOSE REPLACEMENT - This bulletin provides information to replace the Electric Water Pump (EWP) coolant hose on some 2023-2024MY Niro EV (SG2 EV) vehicles produced from July 11, 2022 through January 24, 2024, which may exhibit a coolant leak from under the bulkhead due to a loosened EWP coolant hose at the EWP connector. If the vehicle continues to be driven in this condition, a "Refill coolant" warning message may appear in the instrument cluster, followed by reduced heater performance. The retainer clip on the EWP coolant hose on the vehicle is positioned horizontally on the hose which may come loose after time. The improved coolant hose has the retainer clip rotated 90 degrees to be positioned vertically.
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.
