The contact owns a 2011 Toyota Prius. The contact stated that while attempting to park in a parking space, the vehicle independently accelerated and crashed into a sign post. The contact stated that the brake pedal was depressed during the independent acceleration. There was no injuries sustained. A police report was not filed. The vehicle was repaired by the insurance company. Neither the dealer nor the manufacturer was notified of the failure. The failure mileage was 80,000.
The contact owns a 2011 Toyota Prius. The contact stated that while driving at an undisclosed speed, several warning lights displayed on the instrument panel. The contact stated that the brake pedal was depressed and went to the floorboard which extended the braking distance. The vehicle was included in NHTSA campaign number: 18V684000 (hybrid propulsion system). The vehicle was taken to marietta Toyota located at (750 cobb pkwy S, marietta, ga 30060 (470) 938-8430). The dealer declined to offer the repair because the vehicle had a salvage title. The manufacturer was contacted and offered a software update of the hybrid system but declined to offer any additional repairs. The failure mileage was 101,000.
A few weeks ago my brake and ABS lights came on and my brake pedal changed and became spongy. Since I was still able to brake, I kept driving the car and became used to the spongy pedal. Then the other day I was returning home from work when the car in front of me suddenly hit his brakes. I had to quickly hit mine as well and the brakes locked up sending the car sharply to the right and I crashed into the guard rail causing $1500 worth of damage. I picked up the car today after having the damage repaired but I still have the same problem.
The contact owns a 2011 Toyota Prius. While driving a squilling came from the brakes. The braking distance was extended. The contact was concern the vehicle unsafe to drive. The contact stated that while operating the vehicle a squilling noise was present coming from the front of the vehicle and when pressing the brake pedal the braking distance was extended. The vehicle was taken to the local service center server co Toyota(2841 pukoloa, hi) who diagnosed that the brake actuator was faulty and needed to be replaced. The vehicle was not yet repaired. The manufacturer was not notified of the failure. The failure mileage was 144,000.
I have been lucky to miss closed-call hitting the car in front of me after skidding. When I apply brakes going down the ramp, the car skids and the brake doesn't stop the car until I get pretty close to the car in front of me. I am more concerned because some parts of the road are uneven where I live that increases the chance of brake failure. It happens on surface roads when there is a bump too. The braking distance increase when the street is wet.

When I was about to exit while driving on freeway, myabs, brake, tcs light is suddenly on, the brake need power to push and regenerate charger not working when brake pedal push, and make mpg drop.
When driving over uneven surfaces like potholes and applying my breaks, I feel a delayed response until after I'm out of the pothole. In other words; I apply breaks, go over pot hole, breaks disengage even though the pedal is pressed, and reengaged once I'm on a smooth surface. This has been happening since I first bought my car five years ago, but I always thought it was me over thinking it.
The ABS traction, control and brake light come on for 2 to 3 hours. Then the light will go off throughout the day and then the lights will pop back on and I just went to stop my car went sideways scariest moment ever. The other vehicle on the 2 lane road I was on swerved off the road to avoid hitting me because the vehicle went sideways. At this time all 3 lights were lit up. I drive about 10 hours a day. Please investigate. (nearly died as well as the guy in the other vehicle)
The brake system appears to break down; ABS module and brake booster lose power. This causes braking to be harder and potential safety for the vehicle to lose all braking capability. This issue occurs when braking. There appears to be less air pressure in assist in the braking. Reading online this is a very common issue for the 2011 vehicle! the 2010 model had a recall due to manufacture defect. Https://www.carcomplaints.com/Toyota/Prius/2011/brakes/service_brakes.shtml please address soon because this is a major safety issue!
Brake, traction control, tire pressure, ABS lights all come on while driving. Took to shop. Claims it's the brake booster/ actuator problem. Customer support program
My car spontaneously started showing the ABS system warning light, the "brake" light, and the electronic stability control indicator light without warning while parked. As soon as this happened and I put it in motion, the car began responding poorly to braking, with increased pressure and lack of responsiveness. Additionally, the car is receiving barely any battery charge from the brakes (a small amount compared to the normally full charge), and a whirring noise can be heard about every 3 seconds ( the same whirring noise that occurs when the car is starting up, which I think may be related to the battery). This issue happened while the car was at rest, and affects the car while in motion and at rest. The car feels unsafe to drive due to unpredictability with the brakes and their effectiveness. I believe this issue may be associated with the brake actuator.
After applying brakes car continued to move forward through garage opening crashing into wall at end of garage before it stopped. Brake was not slowing/stopping vehicle
Warning lights for traction control, brake, ave all appeared, and then braking dramatically changed. Almost like not having power brakes. Lights went off and normal brake finction returned. The warning indicator lights go on and off, at random. Code C1391 shows when scanned. This is same symptom as exhibited by 2010 model year priuses covered by recall. Mine is 2011, exact same issue but not covered by recall. Problem has occurred at low 5-25 mph and highway speeds (55-70 mph) this is very dangerous as if this happens at high speed (highway) and the problem occurs there is a sudden change in braking quality an accident may result. This happens when the vehicle is moving, at any speed.
I have an early year 2011 Toyota Prius, the break booster and master cylinder assembly work intermediately. Sometimes it shows errors with lights illuminated on the dashboard and brakes have a lot of play and are spongy and other times they work perfectly normally. The vehicle was in motion and when I went to use the breaks in a traffic situation they ended up hardly working putting myself in a higher risk for a collision and putting my life endanger.
My 2011 Prius very recently has started making audibly noise while pressing the brake pedal, whether in motion or stopped. This noise contains continuous whirring, whining and loud clicking noise. These noises where not seen before completely. I spoke to dealer mentioning a tsb pertaining to this particular issue in specific and was told nothing can be done until it fails completely, which is bad, as I have a family of 3 and god forbid if this were to happen while driving on freeway, a serious safety hazard and Toyota dealer (rudy luther) response is irresponsible. I am actually worried more now on waiting for the brakes to fail. This loud continuous clicking noises occurs the moment car is turned on and the noises lingers on for short while after the car is turned off, at moments I have to press on the brakes really harder than usual to get the car slowed and is a tremendous panicky situation. I am registering and requesting for this to be looked immediately before any catastrophe.
The contact owns a 2011 Toyota Prius. When the vehicle was placed into reverse (when the electric powered fuel motor had not been running), the brakes began to seize when the brake pedal was depressed. There were no warning indicators illuminated. Also, during cold weather, the engine and entire vehicle shook. The contact called precision Toyota of tucson (700 w wetmore rd, tucson, AZ 85705, (520) 795-5565) and notified them of the failures. The vehicle was not diagnosed or repaired. The manufacturer was notified. The failure mileage was 15.
While driving down the highway or interstate, my traction warning light, the brake light, and the ABS warning light all came on, and the brakes became hard to press. When letting off the brake, there was an airy, suction sound. After a while, while driving, all of the warning lights went off, and the brake pressure normalized. There is still an airy sound when I use the brake pedal, though, which always seems to be there, even when the warning lights are off. This has happened about 4 times within the past six months. I had a diagnostic test run, and it gave code #1391, leakage in accumulator abnormal, which pointed to an internal leak in the brake booster/master cylinder assembly. I noticed that Toyota has issued recalls for this same problem in 2010 and prior Prius models, but mine does not qualify because it is a 2011. Since this issue has not been resolved and appears to be a defect in Toyota's brake booster assembly, I would like to see this recall extended to cover models beyond 2010.
The emergency brake light, ABS, and traction lights illuminated on the dashboard. Took the car into the dealer and they reported that the brake booster and master cylinder needed to be replaced. The car was stationary when the lights initially came on and the lights stayed on while it was moving (highway and city streets). The 2010 Toyota Prius was recalled for the same problem. It seems the 2011 continues to have the same problem.
