Service bulletin 23-FL-007H
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.

NHTSA's summary
This bulletin provides the procedure to update the Transmission Control Module (TCM) for the 2022MY Tucson (NX4/NX4a) vehicles and the Engine Control Module (ECM) for the 2022-24MY Tucson vehicles to improve operation of the Idle Stop and Go (ISG) system. Under certain circumstances the vehicle may not restart after ISG system has engaged and require a manual restart due to the lack of intake manifold pressure recovery.
