Brake booster and brake booster pump assembly are faulty and failing. Brakes are still functioning, but will ultimately fail without warning, from what I have read. This is highly dangerous for myself and other motorists. I was driving last week and tried coming to a stop at an intersection. I pushed the brake pedal and the car hesitated and then jumped/lurched forward before coming to a complete stop. The brake booster is sounding every 30 to 45 seconds to try and build back the pressure it is losing. Toyota offered a "Customer Support Program" for these parts, as there's been numerous premature failures. Unfortunately, my vehicle no longer fits within the parameters of the support program (see attached). From what I've read though, Toyota has been negligent with replacing the brake booster under the support program. I have called Toyota Corporate and they have offered no reprieve and won't stand behind this faulty part. Toyota needs to be forced to recall these 3rd gen Priuses and ordered to replace the breaking system. Expecting customers to shell out between $2-3k to have the ability to safely break/stop their vehicle is ridiculous, especially when Toyota is more than aware of this issue. I was quoted $2600 over the phone to remedy the issue from an independent hybrid shop. I've owned 7 Toyotas and two have been Priuses. This 2011 is by far one of their worst to roll off the assembly line with numerous reports of breaking problems, oil consumption issues, and head gasket failures. They need to stand behind their product(s), especially to brand loyal customers.

If I make a longer trip more than 10 to 15 miles the car does fine if I drive it 2 miles down the road or across the street to a different store the car tells me to check hybrid system. I had it check and code c1391 came up and that was repaired. Once repaired picked up from shop drove across the street to gas station and it told me to check hybrid system again and went into limp mode. Once I do a reset the car will start back up and drive fine as long as it's a long trip if I go on another short trip it will do it again.

After approximately 6 1/2 years of owning this 2011 Toyota Prius Hybrid (purchased in 2012), the brake pedal went completely to the floor and there was no braking. The brake fluid was completely FULL. Intermittently, this would occur, but brakes would come back operational in a few minutes. In 2022, the brake lights on dashboard started lighting up intermittently and go off. I had the complete brake pads, etc. replaced in June 2022. Last 1/2 of 2022 the entire brake dash lit up. I got into Toyota dealership 1/12/2023. They said the complete brake Master Cyclinder and Brake Pump replacement was required. They got the dash lights off. This car has only 133,023 miles. I finally checked the internet to see this is a TOYOTA issue! A recall on this brake assembly should be issued! I was unaware of this 5 years ago. This could cause a serious accident and should be fixed at Toyota's expense!

It's doing it again after they supposedly "fixed" it. My family is at risk! If anything happens, I will seek legal action. I can't believe a company as big as Toyota wont take responsibility. And that a recall wont be done. I've seen numerous people report the same issue. PLEASE do something.

My daughter was driving the vehicle on highway and all dashboard lights came on. Abs brake and traction. The brakes would not work. She had to decelerate and pull off and turn car off. Terrifying. Got it checked at Toyota. Told them about that and how car lunges forward when brakes hit on a bump or pothole. We had to pay 2500 to replace brake booster which had an “internal error”. Got car back and all lights came back on. I’m literally terrified to drive my car because of what may happen. Toyota refuses to recall and fix whatever this issue is.

Toyota is recalling certain model year 2010 through 2014 Prius vehicles. In the affected vehicles, the Intelligent Power Module (IPM) inside the inverter module (a component of the hybrid system) contains transistors that may become damaged from high operating temperatures. If this occurs, various warning lamps will be illuminated on the instrument panel and the vehicle will have reduced power allowing it to only drive a short distance.
Consequence & remedy
Consequence: The vehicle may enter a fail-safe/limp-home mode that limits the drivability of the vehicle. The hybrid system could also shut down completely resulting in a vehicle stall, increasing the risk of a crash.
Remedy: Toyota will notify owners and dealers will update the software for both the motor/generator control electronic control unit (ECU) and the hybrid control ECU, free of charge. If an owner experiences a failure of the inverter before the vehicle receives updated software, the dealer will repair or replace the inverter assembly with a new one at no charge. The recall began on March 21, 2014. Owners may contact Toyota at 1-800-331-4331.

Southeast Toyota Distributors, LLC (SET) is recalling certain models interspersed through model years 2009 through 2013 as follows: model year 2009-2012 Tacoma, 4Runner, Camry, Camry Hybrid, Prius, and RAV4; model year 2009-2010 Avalon, FJ Cruiser, and Highlander Hybrid; model year 2010-2013 model year Corolla, Sienna and Tundra; model year 2009-2013 Highlander and Venza; model year 2012 Prius V; and model year 2010-2012 Sequoia. During modification by SET to include accessories such as leather seat covers, seat heaters or headrest DVD systems, these vehicles may not have had the passenger seat occupant sensing system calibration tested. Without passing the calibration test, the occupant sensing system may not operate as designed.
Consequence & remedy
Consequence: If the front passenger seat occupant sensing system is out of calibration, the front passenger airbags may not deploy or they may deploy inappropriately for the passenger's size and position. This could increase the risk of personal injury during the event of a vehicle crash necessitating airbag deployment.
Remedy: Southeast Toyota will notify owners, and dealers will test the sensitivity of the occupant detection sensors, and recalibrate them as necessary. The recall began on March 21, 2013. Owners may contact Southeast Toyota at 1-800-301-6859.

NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition.

On September 19, 2019, the Office of Defects Investigation (ODI) received a defect petition from Mr. Roger Hogan requesting that the Agency investigate and recall certain Toyota Prius, Prius PHV, Camry Hybrid and Avalon Hybrid vehicles for a brake actuator valve wear condition covered under Toyota Customer Support Programs ZJB and ZKK (subject CSP?s). In support of his request, the petitioner identified 117 NHTSA complaints allegedly related to the subject CSP condition, including 60 reporting crashes. On September 30, 2019, ODI opened Defect Petition DP19-004 to evaluate the petitioner?s request for an investigation. In August 2020, the petitioner notified the Agency that he was withdrawing his petition. Because the petitioner has withdrawn the petition, we are denying the petition as moot and no further analysis of this petition is necessary.NHTSA is authorized to issue an order requiring notification and remedy of a defect if the Agency?s investigation shows a defect in the design, construction, or performance of a motor vehicle that presents an unreasonable risk to safety. 49 U.S.C. ?? 30102(a)(9), 30118. Because the petitioner has with withdrawn the petition, the petition is denied as moot. This action does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency notes that it is not required to receive a defect petition prior to opening a defect investigation and will take further action if warranted by future circumstances.
