2011 TOYOTA PRIUS Complaints

I have been doing some research, and the brake actuator and ABS system failing is a common problem on these cars. Mine recently started acting up and they used to replace it for free. I got my Prius only 6 months ago and have not had any luck getting Toyota to replace it. This needs to be recalled it is a serious safety hazard if the brakes suddenly give out. They should be replacing this free on all cars having this issues and they are aware of the issue (Toyota). The brakes suddenly stopped working well and lights came on in this exact instant on the interstate. This first happened about a month ago. Tons of people are making complaints with the NHTSA for the same issue.

12 months ago we noticed a vibration while braking at very slow speed/creeping forward that worsened over time. We didn’t understand the significance at the time. In addition, we noticed more recently the brake pump running more and more frequently, even when the brakes weren’t being pressed. We suspect some sort of problem with the brake booster. This has had many claims against Toyota where my break booster is going out, and I have called toyota to assist since they've had a class action lawsuit that caused them to assist with recalls on vehicles; however the year my vehicle does not qualify for a recall. They opened a service case# 241010002348, but told me it would have to be an out of pocket expense since there's nothing they can do. Unfortunately this is a failure defect on the manufacturers production. Please help.

The low-beam headlamps on thousands of 2011 Toyota Priuses were burning out very prematurely (a matter of weeks, not months). Toyota Corporate said they created a customer support program to replace the headlight wiring harness free of charge, but this program ended in 2019. I believe that Toyota should be compelled to issue a recall to replace the wiring harnesses on all 2011 Toyota Priuses, because working headlights are a critical component of a safely traveling vehicle. The cost of replacing the wiring harness is more than $700, a real dent in a working family's budget. For now, we are replacing the burned-out bulbs. However, we believe a recall initiated by NHTSA is warranted in this case.

The contact owns a 2011 Toyota Prius. The contact stated while her husband was driving approximately 40-50 MPH and depressing the accelerator pedal, the accelerator pedal failed to go back to the normal position and remained stuck. There was no warning light illuminated. The contact's husband depressed the brake pedal, and the engine revved significantly. The driver was able to pull to the side of the road. The driver turned off and restarted the vehicle, and the vehicle responded as needed. The dealer was notified of the failure and referred the contact to the manufacturer for assistance. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 119,000.

The brake booster has failed. I was driving, and the ABS, Brake, and Traction Control lights suddenly came on. The brakes felt less powerful. I drove the car Broadway Toyota in Portland, Oregon for maintenance. I was told that the system has failed, and while this is a known issue. It is not currently covered. I was also told that the car is not safe to drive. Toyota had a "Customer Support Program" to cover this issue. However, the program expired on Oct. 8th, 2021. Had I known, I would have brought it in prior to the expiration date. This seems like a recall issue. In Toyota's paperwork for the Customer Support Program, it states that Toyota is aware of "certain internal malfunctions of the Brake Booster Assembly"!

The contact owns a 2011 Toyota Prius. The contact stated that while driving at unknown speeds or starting the vehicle, the check hybrid system warning light was illuminated. The vehicle went into a Safe Mode. There was no option to place the vehicle in neutral or drive. The vehicle would start but failed to move. The contact stated that the failure was related to NHTSA Campaign Number: 18V684000 (Hybrid Population System). The vehicle was towed to the dealer, where it was diagnosed that there were error codes related to the battery and hybrid system. The vehicle was not repaired. The manufacturer was contacted and referred the contact to the local dealer. The failure mileage was approximately 120,000.

I was driving on a surface street at about 40 miles an hour and then the brakes suddenly don't work. You have to press on the brakes very hard to make them stop. All the safety warning lights were lit up on the dash. Took the car into the Toyota dealership and they said that there was a brake booster and pump customer support program but it's now expired so they won't fix it for free. The brake booster part is about $2000. I contacted Toyota Customer Service and asked them when they sent the notices out for this. They looked up our vin number and said that the notice was sent to the previous owner, since we bought the vehicle used from a Toyota dealer. Spoke to a Toyota supervisor from customer service and told them we never were notified to fix the brake booster. The supervisor said they will not pay for the repair. I think this should be a safety recall and Toyota needs to repair these parts. It's very dangerous to drive the car when the brakes fail to stop.

Brake booster has failed. I'm told this is a known issue but no recall has been issued

To whom it may consern, I avoided a situation that could have been a very serious or deadly accident when my vehicle had unusual issue with the vehicle breaking system while driving on the freeway today [XXX]. The vehicle would not stop while pressing on the break pedal and I was able to quickly maneuver the vehicle on the shoulder of the freeway and was able to avoid a deadly crash. Looked on the dash and noticed that ABS, Break, and Traction Control lights all lit up. I was scared for my life and the safety of others around me. The vehicle was towed to my residence since it happened around 10:30pm California time. Quickly did some researched online for any recall on nhtsa.gov website but unsuccessful with any recall regarding the breaking system. I also found out that it is a common problem that other owners have been/experienced with the same vehicle year, make and model. I would greatly appreciate for any information I can gather in order to assist me on how I can get Toyota to look into this issue for the safety of myself and others. It was a very scary scenario that could have been a tragic one that I found myself into. Looking for a prompt response to address this issue. Thank you!
