“The 2023 Lexus RX-350 has had complete 12 volt battery failure twice in the last year. The hybrid battery charging procedure for the 12 volt battery is insufficient. Twice I have been stranded. The frequency and duration of the hybrid battery charging is not sufficient. A more powerful 12 volt AGM battery is needed. The dealer says I am not taking sufficiently long trips to charge the battery. Last Saturday I took two 30 - 40 minute trips but the battery had only 11.8 volts requiring a 100% charge. There should be a recall to fix this problem.”
NHTSA complaint #11711016, filed 2026-01“I entered then attempted to start my Lexus on November 11, 2025. The car would not start - the dashboard lights fleshed briefly, then the car was completely dead. There was not a light on anywhere. The doors would not open and the windows would not roll down. I was trapped. fortunately I had my cell phone so I was able to call my wife who was inside of our house. She could not open the door with the manual key, She called AAA. The tech hooked up some power device under the hood and the car started and seems OK. This was frightening. I was trapped in the car and running out of air. …”
