Service bulletins for the 2024 Hyundai Tucson

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

25-01-010H-1 TSB2025-07-22. Service campaign. ELECTRICAL SYSTEM. This bulletin provides the procedure to update the software for the Battery Management System (BMS) on certain Elantra Hybrid (CN7 HEV), Sonata Hybrid (DN8 HEV), and Tucson Hybrid (NX4 HEV) vehicles that may exhibit a warning light with DTC P1BB200 and enter Limp Mode.
25-01-024H-1 TSB2025-05-27. Service campaign. ELECTRICAL SYSTEM. Some vehicles may exhibit a loss of connectivity or interruptions in the middle of using Bluelink Service functions. This may be due to an irregular disconnection on Verizon’s communication network. Follow the procedure in this TSB to reestablish the connection via the AVN pinhole reset method.
25-01-024H EM2025-04-18. Service campaign. ELECTRICAL SYSTEM. Some vehicles may exhibit a loss of connectivity or interruptions in the middle of using Bluelink Service functions. This may be due to an irregular disconnection on Verizon's communication network. If you are experiencing issues with remote commands, or other Bluelink services, please see the instructions below to reestablish the connection via the AVN pinhole reset method.
25-01-024H TSB2025-03-25. Service campaign. ELECTRICAL SYSTEM. Some vehicles may exhibit a loss of connectivity or interruptions in the middle of using Bluelink Service functions. This may be due to an irregular disconnection on Verizon’s communication network. Follow the procedure in this TSB to reestablish the connection via the AVN pinhole reset method.
25-01-023H TSB2025-03-17. Service campaign. ENGINE. The exhaust gas recirculation (EGR) valve assembly in certain vehicles (listed below) may contain a sensor that was contaminated with solder flux during manufacturing, which could potentially result in an electrical short. An electrical short within the EGR valve could lead to a Malfunction Indicator lamp (MIL) illumination (P0405, P0642, P0652, P0404/P049D/P240F). Follow the information in this bulletin to replace the EGR valve assembly and gasket.
