I had just changed from the right-hand lane to the center lane of a six-lane expressway when my vehicle lost power and i was able to move over to the right hand shoulder of the road. The accelerator pedal did not work and I just coasted to the side of the road. I noticed that a red warning saying something about RADAR flashed on the instrument panel when this happened. I turned off the vehicle and tried to restart it, but nothing happened. I then texted the person who was expecting me and explained the problem. Since I had just taken the car to the dealer for its regular 40,000 mile service four days earlier, I intended to call my dealer to ask them what to do. All of this took about 10 minutes with the engine turned off. Before doing this, I again tried to restart it. It started and I inched it forward on the shoulder of the road. Since I did not feel safe parked on the shoulder, I merged into traffic and took it to another Toyota dealer. They said that they could not look at my vehicle to diagnose what might be wrong because all their technicians were going home at 4 pm. I drove to my son's house and he suggested that I report this to you. Something similar happened to him when he was driving this same vehicle about six month ago. He was driving on a city street, did not notice any dashboard warning, and took it to this same dealer. They were not able find anything wrong. I felt I should report this since this is the second time this vehicle suddenly lost power. My incident happened when I was driving at expressway speed and could have caused a serious accident had I not been able to coast to the shoulder of the road.

This is for 2017 Toyota Prius prime, but there is no option. While taking my kid to enroll in swimming class, while taking turn into the facility the brakes stopped working and the car wouldn't stop, some how I drove into parking lot (I am not sure how I did it in that tense situation) none of the buttons were working, the car was beeping showing every thing failed and by gods grace the hand brake worked and finally the car stopped. Now I am scared as this happened with my kid in the car. I need help and I don't want to drive this car again and I towed it to the Toyota dealer. After exiting I calmed down a little bit called my husband and he recorded the errors and the sounds. I thought the car was going to blow up.

While I am slowing to a stop, a warning light comes on indicating that I am pressing the brake and the accelerator at the same time. This is not possible. The car does try to move forward but pressure on the brake overcomes that issue. This has happened multiple times (not every time) but fortunately no accidents have occurred. This has also never happened when I am driving at highway speed and need to brake.

The involved vehicles were designed to enter a failsafe driving mode in response to certain hybrid system faults. Toyota has found that in rare situations, the vehicle may not enter a failsafe driving mode as intended. If this occurs, the vehicle could lose power and stall. While power steering and braking would remain operational, a vehicle stall while driving at higher speeds could increase the risk of a crash.

Car started by itself when it was parked in a driveway in hot weather in the sun. My key fob does not have a remote starting mechanism - only door unlock and lock capability.
