2024 Lexus RX 350 problems

“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…”

“Cruise control engaged and going 70mph. Brakes engaged and brake light came on in dash indication crash braking. Brakes slammed on and car decelerates to 5 mph before getting operating control back. No cars within 200 ft no road obstacles. Acceleration did not respond and unable to gain control and prevent danger problem.”

“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.”

“On [XXX] at approximately [XXX] PM, I was reversing my 2024 Lexus RX 350 out of my garage when the left rear passenger door (the door behind the driver) popped open while the vehicle was moving. The door struck the frame of the garage door opening and was damaged so badly that it will not close. Before I started reversing, the door was closed. There were no warning lights or messages on the dashboard, and no audible warnings sounded when I put the vehicle in reverse or while it was moving. The vehicle has approximately 12,000 miles. The same day, [XXX], I took the vehicle to Westside Lexus Certified Collision Center, 11960 Wickchester Lane, Houston, TX 77043. My insurance claim number is [XXX]. The estimator, Jesse Price, told me he had seen this before and quoted approximately $5,000 for the repair. When I asked whether there are known defects related to this type of event, he did not respond. I am concerned that the rear door latch may be defective and could allow a door to open unexpectedly while the vehicle is moving, which is a safety risk to passengers and others. I request that NHTSA review whether other owners have reported similar incidents.”
