2011 TOYOTA PRIUS Complaints

All brakes warning light went on while driving. The anti skil, abs, emergency brake lights. The car was unable to stop and code reader indicated a brake booster pump and brake actuator/accumulator failure. The failure was confirmed, and the brakes just stopped working while driving. I almost crashed into another car as the brake was not working no matter how many times I press it. Contact Toyota, they are careless and said it was not cover in any recalls and an enhancement warranty just passed 4 months on my car. A previous voluntary recalls was issue for the car model year before mine. This is a fundermental feature of a car and should be fix regardless of age. It is putting people's lives in danger and will cause accident!

The contact owns a 2011 Toyota Prius. The contact stated while driving approximately 55 MPH, the vehicle stalled with the check hybrid system warning light illuminated continuously. The vehicle was able to restart. The vehicle was taken to the dealer where it was diagnosed that the inverter needed to be repaired. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 141,000.

Brake System Warning light ABS warning light Slip indicator light 6/3/2022, while driving on the highway the above warning lights illuminated. I depressed the brakes but failed to engage. I was able to slow down by shifting the gear into “B”. Eventually the brakes engaged and I brought the car to a stop. Toyota created customer support program ZJB but the warranty covered a period until August 2021.

The brake system failed. Over time there was a frequent sound (which I now know is the brake pump) when you opened a door. Eventually at 120K the entire brake system failed throwing the ABS code. I had to replace the brake actuator and booster (2 parts are recommended in the repair) for a little more than $1500. After speaking with the parts rep at Toyota (I replaced it with geniune Toyota parts) I was under the impression that the parts person knew that people frequently buy these parts which led me to believe something was known but not divulged.

While driving on the freeway 3 warning lamps lit up: parking brake, traction control & the "!" (attention warning light). I was about to exit and while braking noticed my brakes were not working well. It required at least twice the muscle effort to stop and took a further distance. Prior to this the brakes seemed to have been working perfectly. I stopped at an Autozone on the way home and they scanned the C1391 error code. A quick internet search showed that this had been the subject of a recall for the year and model of the car: 2011 Toyota Prius. I have not yet taken it to the dealer but understand the recall no longer covers this year. However, the safety of myself and passengers was definitely at risk due to a known problem of this car.

Driving on a cross country trip and went over a bump to have all the brake lights on the dash illuminate and brake system failed. Brakes were very hard to push but was able to safely stop the vehicle. Brought it to Toyota dealership and was told that the master brake cylinder, hydraulic brake booster and pump assembly needed to be replaced and that the vehicle was not safe to drive. I was advised that the parts are on national backorder and they don’t know when they’ll get the parts. I did more research into this and this is a known issue that Toyota has refused to address outside of a limited program that is no longer active for this model year. Toyota is refusing to cover any of the costs. This is an incredibly dangerous safety issue and Toyota should be forced to recall and reimburse everyone who has had this issue regardless of model year or mileage. Toyota is currently facing a class action lawsuit for this issue as well.

All the brake lights, ABS, and VSC lights came on, lucky I was not on the road. Now my brakes are mushy and I'm driving without any safety. I learned of the Customer Support Program - ZJB, but it expired for my 2010 Prius w 85k miles on 8/31/2021. I called Toyota Cooperate Office, they could not care less. They told me it is expired, bye! They need to make this a recall as the it is a major KNOWN problem for many cars. Repairs will run $3500 plus. This is my 2nd Toyota I bought brand new, and my last if Toyota is not willing to help.

Traction control, ABS, and brakes come on all at once and brakes don’t work properly. This happened a few times on the freeway and thank god I didn’t get into a crash. Car doesn’t feel safe to drive. I took the car to a mechanic to check the codes and the code C1391 (abnormal leak in accumulator) came up. I see that this is a very common problem with Gen 3 Prius’. Toyota has not called these car even though the problem seems to happen to all Prius’s of that generation. This is very dangerous and I fear driving my car and that the brakes might completely fail potentially causing a crash at accelerated speeds.

Our Prius started showing brake issues in June 2021 that has us concerned about safety. The car lurches when the brakes are pressed, and the brake functions inconsistently. This seems to fall under the “brake booster pump assembly with master cylinder” issue that many others have complained about. When we called Toyota, they said a letter was issued in April 2019, but when we took the car in for diagnostics in August 2019, the brake issue (diagnostic code) didn’t appear then. So they said they won’t fix the hazardous defect. Even more troublesome is the fact that this issue has caused crashes and injuries in the past, and Toyota hasn’t issued a recall. Please help consumers hold Toyota accountable for putting their customers in harm’s way.
