The vehicle is experiencing a critical failure of the Brake Actuator and Booster Pump assembly. The dashboard currently displays multiple warning indicators: ABS light, Traction Control light, and the Brake System Warning light (Master Warning "!"). Symptoms: Mechanical Failure: The internal high-pressure accumulator is failing to hold pressure. The electric brake booster pump is heard cycling every 10-20 seconds even when the vehicle is stationary and the brake pedal is not depressed. Loss of Braking Safety Features: The system has disabled regenerative braking and Anti-lock Braking (ABS), causing significantly increased stopping distances and a “spongy" brake pedal feel with diminished braking response. Predictability of Failure: This failure matches the exact symptoms described in Toyota's Customer Support Program 20TE07 (and previously ZJB), which acknowledges an internal defect in the brake actuator. Safetv Risk: The sudden transition from power-assisted braking to manual hydraulic braking during a drive creates an immediate safety hazard. As the pump motor continues to cycle excessively to compensate for the internal leak, it is at risk of total thermal failure, which would lead to a near-total loss of braking assist while the vehicle is in motion. Despite the vehicle having only 75,689 miles (well under the 150,000 mile limit acknowledged in Toyota's support programs), Toyota has declined to provide assistance because the vehicle has surpassed the 10-year age mark. Toyota is wrong in not providing support for vehicles whose critical components such as brakes shouldn’t experience catastrophic internal failure at 75,689 miles, regardless of the vehicle's age.

What 2014 Toyota Prius V owners say
Most recent owner complaints, unedited.
In 2024, I had my vehicle checked out prior to a road trip because the brakes were making "fart noises," and I was worried about driving it to Albuquerque. The AAA certified dealer I took the car to said everything checked out alright. I never received the letter regarding the brake system issue, so I could not take advantage of the extended warranty repair program. My car was in the 80-90 thousand mile range and had not yet rolled over. Fast forward to 2025, my dashboard lit up all over the place, and I got the brakes checked again. By that time, the fault code was coming up, but the entire ABS system needed to be replaced. I was unable to get any help from TOYOTA despite this being a KNOWN FAULT WITH TOYOTA PRIUS AND TOYOTA PRIUS V FROM THIS TIME PERIOD. They are STILL not doing anything to help their customers. Brake issues are EXTREMELY dangerous, and it is wildly negligent to continue moving forward WITHOUT fully recalling the ABS system in the FULL LINE of prius vehicles from the impacted manufacture dates. Every prius owner I know has had to deal with this. My care was UNDER the required mileage but PAST the dates to be repaired. PLEASE consider holding TOYOTA responsible and getting them to refund Prius owners who have already paid for this COSTLY repair out of pocket. Thank you.
N/a
I purchased a 2014 Toyota Prius V in 2013, and it currently has 120,000 miles on it. Last month, the engine light came on, so I took it to a dealership. They diagnosed the issue and provided the codes P0302 and P0304. After consulting multiple shops, all confirmed that coolant is leaking into the engine, which means I either need to repair the head gasket or replace the engine entirely. The quotes I've received for this repair range from $5,000 to $15,000, while the current value of the car is only about $5,000. I want to file a complaint regarding Toyota's responsibility for these engine issues. We buy cars because we trust the brand, and in this case, Toyota has broken that trust. Despite maintaining the car according to Toyota's recommended schedule, I have encountered this serious problem.
Description of the Problem Vehicle: 2014 Toyota Prius v (Mileage: 70,000) Problem Description: The vehicle is experiencing a critical failure of the Electronically Controlled Braking (ECB) system, specifically the Brake Actuator and Booster Pump assembly. The dashboard currently displays multiple warning indicators: ABS light, Traction Control light, and the Brake System Warning light (Master Warning "!"). Symptoms: Mechanical Failure: The internal high-pressure accumulator is failing to hold pressure. The electric brake booster pump is heard cycling (straining) every 10–20 seconds even when the vehicle is stationary and the brake pedal is not depressed. Loss of Braking Safety Features: The system has disabled regenerative braking and Anti-lock Braking (ABS), causing significantly increased stopping distances and a "wooden," unresponsive brake pedal feel. Predictability of Failure: This failure matches the exact symptoms described in Toyota’s Customer Support Program 20TE07 (and previously ZJB), which acknowledges an internal defect in the brake actuator. Safety Risk: The sudden transition from power-assisted braking to manual hydraulic braking during a drive creates an immediate safety hazard. As the pump motor continues to cycle excessively to compensate for the internal leak, it is at risk of total thermal failure, which would lead to a near-total loss of braking assist while the vehicle is in motion. Additional Notes: Despite the vehicle having only 70,000 miles (well under the 150,000-mile limit acknowledged in Toyota’s support programs), Toyota has declined to provide assistance because the vehicle has surpassed the 10-year age mark. I am filing this report because a primary safety component (brakes) should not experience catastrophic internal failure at 70,000 miles, regardless of the vehicle's age.
I have 2014 Prius v 5 with 100,000 miles but I had issues with brake booster pump
8/2025 Car stalled on freeway. Went to dealer. They said nothing wrong. Then on a trip north, car stalled again on freeway. Went to the nearest dealer. They too said nothing wrong. This time same thing. There is a recall for the exact symptoms of the exact car yet they say the repair was done. Why does my vin not qualify for the exact symptoms that generated a recall? This was super dangerous at freeway speed. Toyota knows there is a problem with the inverter and it's computer. Now I'm paying again for a diagnosis. That makes $750 just diagnosing and now if they actually decide it is the inverter, I have to pay upwards of $3000 even though there is a recall? What the heck?
The brake booster has failed and seems to be a common issue with this model vehicle for Toyota issued an extended warranty, but I am passed the date and they are unwilling to do anything. Due to the malfunctioning brake booster. The car is unsafe to drive the too expensive to repair.
Brake booster is not working
The contact owns a 2014 Toyota Prius V. The contact stated that while driving approximately 35 MPH, the brake light, tire pressure, traction control, battery, and other warning lights were illuminated. While attempting to depress the brake pedal, there was more resistance than normal, making it difficult to slow the vehicle. The contact was able to drive the vehicle to the nearest mechanic; however, the vehicle was not diagnosed. The vehicle was then taken to the residence. The vehicle was taken to another certified mechanic, who diagnosed and determined that the brake master cylinder and actuator assemblies had failed. The brake master cylinder and brake actuator assemblies were in the process of being repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 220,000.
