Service bulletin L-SB-0012-26
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
Some 2023 — 2025 model year RX 350h customers may experience a high engine RPM/noise when coasting or braking when going downhill with high vehicle SOC (State of Charge). This condition may occur when the vehicle is utilizing engine braking to prevent overcharge of the hybrid battery (>80%).
