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.
