We were driving in San Diego and had driven oven a bit pothole. About 50 miles after driving over the pothole, the brakes stopped working. We were pressing down hard on the brake, but the brake was soft and did not do its job. We almost rear ended the car in front of us. We brought the car right away to a close by auto shop and they said there were no leaks as the brake fluid was still close to the max and they did not find any indication of a brake fluid leak and sent us on our way. We are still unsure as to why the brake from this vehicle stopped.

When putting the car in park and then engaging the foot parking brake on a slope, such as my driveway, and then turning off the car, the car rolls back significantly. Then, while exiting the car, the rear brakes make loud grinding and creaky noises as the car settles downwards slightly. Then, when entering the car, the brakes make the same creaky and grinding sounds. When holding the brake pedal to power on the car, then disengaging the foot parking brake, then shifting the car from park to reverse or drive, the car jerks abruptly and at the same time makes a loud and stuck disengagement sound, as if the car was being held on the hill/driveway solely by the parking pawl. It seems like the parking brake is not holding the car, and instead, the parking pawl is.

The contact owns a 2016 Toyota Prius. While the vehicle was reversing and depressing the brake pedal, the vehicle jerked while coming to a stop. There were no warning indicators illuminated. As a result, the contact had to release the brake pedal to stop the vehicle. The vehicle was taken to city Toyota (255 san pedro rd, daly city, ca 94014, (650) 204-8135) where it was diagnosed that the brake actuator needed to be replaced. The vehicle was repaired, but the failure recurred. The dealer advised the contact to schedule a diagnostic appointment. The manufacturer was made aware of the failure. The failure mileage was approximately 17,000.

When the car is in drive and stationary on a hill facing up wards (like in a driveway) the car still sends electrical power to the electric motor and to the wheels even when the brakes are applied. This only happens when facing up a hill. All electrical power is suppose to turn off when the brake is pressed. This started happening two weeks ago and the dealership said that this is normal but it is not normal as it never did this before. It does not happen when on flat ground or when facing down hill. Dealership claimed that this is the hill assist feature holding the car but that's a lie as the hill assist utilizes the brakes and not the motor. Dealership could not find any error codes and refused to dig further into the issue and made up lies about it.

Over the past year and over 15,000 miles our 2016 Toyota Prius four touring has experienced sudden displays of warning messages and lights reporting braking power low - visit your dealer; braking power low - stop in a safe place - see owner's manual; pre-collision system malfunction - visit your dealer; anti-lock brake system malfunction - visit your dealer; lane departure alert malfunction - visit your dealer; ics malfunction - visit your dealer; check cruise control system - visit your dealer. The following codes/faults have been detected: ABS - C1403, C1407, C1415; parking sensors - C164D, C1A50; blind spot monitor - C1A45; blind spot monitor slave - C1A45; pre-collision system 2 - C1A50; lane-keeping assist 2 - C1A50; ECU - P157800 & cruise ECU - P157800. The warning messages/lights came and went while driving on both city streets and highways. Each time I took the vehicle to the dealer. They could see the codes in memory, but could not replicate the problem. No parts were replaced. The only thing they have done is to take apart and reseat some of the connector cables and then send us on our way telling us to bring it back in if it happens again. We are seriously concerned about the safety of this vehicle and have no reassurance that the problem has been resolved and no reassurance that major braking systems might not be available to me if it occurs again. I contacted Toyota customer assistance with no change in their position. I am currently negotiating to trade the vehicle in as I am not comfortable that the problem is resolved and deeply concerned that it will happen again. I have shared video of the warning messages and lights with the dealer, but am unable to upload video here.

When breaking while traveling over bumps/ripples on the road or over rough road conditions such as potholes or roadwork, the vehicle feels as though the breaks are skipping or failing. This has occurred multiple times under the same or similar conditions. There is a sensation while attempting to stop, that the car is not going to stop in time or that you have lost control of the vehicle's ability to stop safely.

Vehicle feels like it wants to go forward as soon as the gas engine turns on to charge the hybrid battery when it is stationary, is in park gear with the foot parking brake fully on and on a flat surface. When the car is running off of battery mode and the battery becomes depleted the gas engine turns on to charge the hybrid battery, you can feel the car sending power to the wheels for a slight two seconds and can also hear the brakes creaking as a result of the engine feeling engaged to the wheels even when the park gear (/button) is selected. It happens all the time and not sure why it would do that while in park. If a parking brake failure was to happen what would happen when the engine turns on to charge the battery again" will it creep forward or what" just thought this was a concern since I have not experienced this with non hybrid cars.

On Friday, October 21, 2016 while driving over a pothole I pressed on the brake. The car slowed but all of a sudden the brake suddenly depressed even further down and the car jerked and seemed to stall before pushing forward. I had been pressing the brake as far down as it would go and it seemed as if there would be some kind of brake failure. On October 31, 2016 while driving over another pothole, I again stepped on the brake and suddenly the pedal again depressed further down and there was a creaking and squealing sound. Then on November 4, 2016 while going over a pothole, there was a squealing and creaking sound but not a sudden additional depression of the brake pedal. All these incidents happened on salt lake blvd. Or kamehameha highway and passes under the fixed guideway for Hawaii's rail system. The road is extremely bumpy and full of potholes.

As I took a highway exit, following behind other cars doing the same, my Prius refused to brake efficiently when another car abruptly invaded our line. It felt as if the brakes made a slight release or couldn't reach a full stop. I had enough space to stop, and I pressed the brakes on time but there was almost no brake reaction and I crashed into the truck in front of me. I was probably going 20-30 mph, somewhere in the middle... so not even that fast. Best part is that the airbags didn't inflate, even though the car was almost totaled. This feels explainable to me... I had it for only two months thus far. I do not recommend this car to others.

When gently applying brakes for a stop light, and the right wheel hits a 1 and 1/8 inch deep depression in the road, the brakes feel like they momentarily release. The depression is for a 9 inch diameter city water cover, and the overall diameter of the depression is 12 inches, and it is 1 and 1/8 inches deep. This can be replicated at this location and we have also noticed the same thing happening elsewhere in town.
