WARNING: This page is about a different car, the 2025 Lexus RX 450h+ and 2024 Lexus RX 450h+. However, it is still accessible from the selected car via links, so may be relevant.
The battery ECU assembly monitors the SOC (state of charge) of the HV battery. When it finds the HV battery has deteriorated excessively, it will display "Maintenance Required for Traction Battery at Your Dealer" on the multi-information display. If "Maintenance Required for Traction Battery at Your Dealer" is displayed, perform "Battery Diagnosis" and replace the HV supply stack sub-assembly as necessary.
