   A 2024 Lexus RX 350 H 12 volt battery is discharging leaving owners stranded. AAA must be called to jump the battery. This has happened four times, each when opening car doors to clean the vehicle. From my understanding the battery discharges within 5 minutes leaving the auxiliary system without power and the inability to start the car. Not exactly sure what is causing the battery drain but vehicle becomes unable to move, open doors or move since drive train will not allow any movement. Owners have been stranded four times waiting on help. Dealer unsure of problem but exploring electrical issues, battery issues, software issues or unknown issues.

   I have tried to get Stevenson Lexus in Lakewood Colorado to replace the head rests , they have not ever had the parts to complete the recall. I have been waiting for over a year. I called Lexus headquarters in Texas and was told that there is a remedy but Stevenson Lexus has never offered that to me.

   While on a long road trip on a hot day, on the interstate, the car suddenly lost speed and would not accelerate. It was like the car had shifted into neutral. I was coasting on the interstate, steadily slowing, and was forced to pull over to the shoulder. I turned the car off and waited a couple of minutes then turned the car back on. No error messages were displaying at that time. About 5-10 minutes later, I pulled over for a planned stop. My husband assumed driving responsibilities when we got back into the car. Upon trying to get back on the interstate, the car would not accelerate, and multiple errors error messages appeared, including: ""System Malfunction/Visit Your Dealer," "Check Engine/Visit Your Dealer," "Drive-Start Control Malfunction/Visit Your Dealer," "Secondary Collision Brake System Malfunction/Visit Your Dealer," and "Traction Control Turned Off." He pulled into a nearby parking lot where we had to have the car towed to the dealership. It felt like the car was in neutral when this happened both times.

   When in cruise, the car will merge itself into the next lane if you hold the turn signal partially. If you keep holding it or fully engage the turn signal (maybe you forgot to turn off you signal, or held it too long), the car will merge through the solid white line off the road into a ditch. This happened to me once, and I noticed it trying several other times.

10. Filed Mar 7, 2026Failure Mar 5, 2026Anaheim, CAElectrical system, 12v/24v/48v battery2 injured

    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)

    On Feb. 10th 2026 I was driving north I405 (Los Angeles). The car suddenly applied emergency breaks in the middle of the freeway, while there was no car in front of me, at least for 100m. I was lucky that the car behind me didn't hit me. It could be a serious multi-car collision.

12. Filed Feb 2, 2026Failure Jan 28, 2026Austin, TXElectrical system, Unknown or other

    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”

13. Filed Jan 29, 2026Failure Jan 21, 2026Pompano Beach, FLEngine, Power train

    When coming from a stop, the car will not respond to the gas pedal being engaged OR it will begin to engage and then no response leaving the car rolling for a few seconds until a response is recieved and the car engages again. This has caused us to be put in harms way MANY times with oncoming traffic when making turns or in front of oncoming traffic in intersections. The dealer states this is not a known issue however it is all over the internet that hundreds of reports of this issue have been made. The dealer states no fix since they don't "have a problem". MAJOR safety issue. We have reported this many times to Lexus now with no resolve or help from them.

15. Filed Jan 14, 2026Failure Jan 14, 2026Chester, VAEngine

    When accelerating at slow speed, the engine or turbo turns off which causes the nose of the car to take a hard nose dive and then turns back on within 1 second but results in a big loud sound coming from engine/transmission. This issue almost caused on accident because it does a hard engine break where I was almost rear ended but from other drivers perspective, it might seem that I’m break checking them. Showed car to Lexus but they said it is normal but it not normal and should be investigated as it can cause harm to everyone involved if accident were to occur. Situation occurred 3 times this week and it is entirely random and can’t replicate at will.

16. Filed Jan 3, 2026Failure Oct 30, 2025Santa Ana, CAAutomatic emergency braking

    I went to reverse the car. Suddenly, the car's automatic emergency breaking system engaged. This occurred on 2 separate occasions. The first time, was in a parking lot during a sunny day. There was definitely nothing behind me, not even a person, but the camera saw a leaf or something small, and engaged the automatic emergency brake. The second time, it was raining in the evening, the sky was dark. I went to reverse (to complete a u-turn in an empty lot). Suddenly the automatic emergency braking engaged. In both instances, if I was reversing (as part of a u-turn on a busy street, this would have been very dangerous. Please investigate this. It was very scary.

17. Filed Jan 1, 2026Failure Sep 14, 2024Los Altos, CAElectrical system

    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.
