“My 2023 Lexus RZ450e experienced a sudden failure of the 12-volt battery, which completely disabled the vehicle and prevented it from starting. The battery failed while the car was plugged into a Level 2 home charger, but not in ‘Ready’ mode. There were no warning signs or alerts, and I had to call roadside assistance to jump-start the car. After the incident, I brought the vehicle to the dealership. They tested the 12V battery and said it was “fine.” However, during the 100,000-mile maintenance, I specifically requested a battery re-check—and this time, the battery failed the test. …”
