I am reporting a safety concern involving a 2024 Lexus RZ300e related to battery range performance and charging requirements in cold weather. In real-world winter conditions in Massachusetts, the vehicle experiences severe range loss, requiring excessive and repeated public charging to remain operable. On a representative day, I was required to use multiple public charging networks (ChargePoint, FLO, and Tesla Superchargers), spending over 4 hours physically charging, consuming approximately 105 kWh of electricity, and paying nearly $50 in public charging costs, with additional home charging

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. This

This evening upon driving home my 2.5 year old son began crying. When I investigated, he was crying because his car seat had turned over on its side. When we arrived home I tested the rear seat belts and none remain locked; therefore his seat was not secured. Please advise how this can be fixed as soon as possible as it is not safe for us to use the vehicle until this is addressed.
