LEXUS UX HYBRID 2025 FUEL/PROPULSION SYSTEM
high
This is a new vehicle. It had been serviced according to the manufacturer’s recommendations at 5000 miles, around 3 weeks prior to the date of this incident. While driving on the freeway, I got an alert that the check engine light came on and there was a “malfunction in the electronic control of the engine, throttle, or automatic transmission has been detected”. Shortly after several more alerts popped up: “a malfunction in the hybrid system” and “a malfunction in the Drive Start Control System” were detected. While attempting to get to a safe location to pull over, the throttle no longer functioned. I was able to coast down an off ramp. Once stopped at the light at the off ramp, the accelerator pedal no longer worked and the vehicle was stopped blocking a lane of the off ramp. After waiting and restarting the car, I was eventually able to pull to a safe location away from the off ramp before the engine failed again.

high
Driving a Lexus UX300h 2025. Making a right turn from an alley onto a driveway of a house in low speed. Then the car was malfunctioning and suddenly unintended accelerated, and the front end on the driver side hit the brick structure of garage. The car is equipped with Lexus Safety System + 3.0 with Pre-Collision System (PCS). However, the system did not give any warnings to the driver of an impending collision and the Crash Imminent Braking did not apply the brakes automatically to slow or stop the car avoiding the crash.
