I am reporting a recurring electrical and mechanical system failure on a 2024 Lexus RX 350h Luxury. On [XXX], the vehicle suffered a total power loss that rendered the electronic door latches unresponsive to all inputs. Because the occupants were a [XXX] and a [XXX] strapped into car seats, they were physically unable to reach the interior manual overrides. Critically, the mechanical backup key also failed to unlock the vehicle from the exterior, preventing immediate rescue. This created a life-threatening entrapment scenario. The doors only responded after multiple minutes of repeated manual attempts. Once entry was gained, the vehicle would not start and the headlights began blinking rapidly, indicating a total system communication failure. I had to use jumper cables to restore power. This is the second occurrence of this catastrophic failure, documented on Repair Order [XXX] at Lexus of Westminster. The failure of both electronic and mechanical failsafes constitutes an extreme occupant safety hazard. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2024 Lexus RX 350h experienced a catastrophic 12V battery collapse (2.00V), disabling the electronic 'e-Latch' door system and rendering interior handles non-functional for standard use. While a manual override exists, it is not intuitive for emergency egress. Additionally, the electronic parking brake and shift-by-wire systems remained physically locked, preventing the vehicle from being moved to a safe location during the power failure. I am reporting this as a failure of primary safety and fail-safe protocols. Dealer did not consider this a a problem because he said I “needed to read the manual before I ever drove the car”

The car started showing multiple error messages on the dash and then shut off while in operation, it would not restart without a service call and battery boost. This has happened multiple times. Online research shows this is a common issue with the hybrid models - the 12v battery doesn't get adequately charged, voltage drops and car ceases to work - even while mid drive on the road, this is extremely scary and dangerous.

Battery has "sulfated" twice in 15 months of ownership. Lexus/dealer have replaced battery two times. Considered safety issue since battery could "die" at any time. Could be locked out of car with infant inside or if battery dies while driving, car could become immobile.

Was pulling into parking spot when car went haywire and started accelerating on its own. It would not stop until it has hit 5 cars and crashed into a cement wall. The brakes did NOT stop the acceleration. This occurred at the exact same time there was an incoming call which was not answered. The airbags did NOT deploy. The car appears to be totaled and has been towed to a State Farm affiliated auto yard. There were no indicator lights that something was wrong BUT the Lexus app showed 5 warnings that came in to my text messages same day. These 5 alerts are indicative of exactly what occurred.

The vehicle would not start. It is a known problem with this PHEV that if car is not used for a couple of days the 12v battery becomes depleted and the car cannot be started and all systems of the car are dead.

When I start to coast to come to a stop the engine will rev, even though the Energy Flow screen shows the gas engine is disengaged and running only on EV. The engine will rev, even with me using the brake. But the EV light is off and the rpms are rising. Eventually the EV light will come on and the gas engine will cut off and the vehicle will switch to EV mode. My mpg has dropped to 36.2, so something is not right. When I was at the dealer for my 10K service, they told me this was the car "shedding" the extra energy, but the battery was not fully charged, so I'm perplexed and frustrated.
