2024 Lexus RX 350Recalls, problems, MPG & safety

“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.”

“My 2024 Lexus RX 500h experiences an intermittent failure to respond when I press the accelerator pedal. During these episodes, pressing the pedal does not produce the expected acceleration, making the vehicle’s response unpredictable. Lexus service bulletin L-SB-0026-25 was performed on my vehicle to address the issue. However, the accelerator nonresponse continues after that repair. The issue remains unresolved. I am concerned that an unexpected inability to accelerate could leave my vehicle exposed to approaching traffic when entering a roadway or crossing an intersection. This is a safety concern because I cannot reliably count on the vehicle to accelerate when needed. I request that NHTSA review this recurring loss of accelerator response, including cases where the condition persists after the software update. The underlying cause of my vehicle’s continued problem has not been established.”

“On October 30, 2026, at approximately 1:00 AM, I experienced a serious and unexpected safety incident involving my 2024 Lexus RX 350. While slowly parking my vehicle in my garage, at a very low speed and nearly at a complete stop, the vehicle suddenly accelerated forward without my intentionally pressing the accelerator pedal. At approximately the same time, the steering wheel appeared to lock or become unresponsive, preventing me from maintaining control of the vehicle. The vehicle surged forward and collided with my garage door, causing property damage. Additionally, the vehicle's Pre-Collision System (PCS) / collision protection system did not appear to activate or intervene to prevent or mitigate the impact. I did not observe any effective automatic emergency braking intervention before the collision. I am extremely concerned about the possibility of a malfunction involving the electronic throttle control, braking system, steering system, or other electronic vehicle control components. The cause has not yet been determined. I reported the incident to Lexus USA on October 30, 2026, and a safety case was opened under reference number 26103000582. I have…”
