On the evening of October 29, 2025, my 2025 Lexus RX 450h+ suffered two complete electrical failures within a few hours. The vehicle lost all power and became totally unresponsive — no lights, sounds, or electrical function. During the first failure, both of my young children (ages [XXX] and [XXX] were trapped inside because the doors would not unlock or open manually from the inside or outside. The failure occurred at night, and I was stranded for nearly five hours. I repeatedly tried to reach Lexus Roadside Assistance, but the calls disconnected multiple times before I reached an agent. A tow truck was dispatched with a 90-minute ETA, but before it arrived, the vehicle suddenly restarted on its own. We finally got home close to 1:00 a.m. I am a single parent and this was a terrifying, unsafe situation that could have resulted in serious harm if my phone had died or if outside help had not stopped to assist us. The vehicle was brand new (leased April 2025) and has approximately 5,000 miles. It was taken to Serramonte Lexus for inspection, and Lexus Corporate is reviewing my request for replacement or buyback. This is an extremely dangerous defect affecting the 12-volt electrical system and electronic locking mechanisms. The vehicle doors should never be inoperable during power loss, especially when children are inside. I am filing this report so NHTSA is aware of this incident and can investigate whether similar failures are occurring in other 2025 Lexus RX 450h+ vehicles.
