2007 Toyota Prius brakes problems

Filed Jun 5, 2025 · Brakes · AL

The brake actuator failed. When the car was diagnosed by the Toyota dealership, they identified the problem as an internal leak within the brake actuator. Luckily, nobody has been hurt attempting to drive the car, but it is still being driven to get it from home to the repair shop so anything is possible. The first symptom I could link to this was in 2023, when the car would not accelerate via the gas pedal after the brakes were pressed during cruise control. Turning off the car and turning it back on fixed the problem. Afterwards, the red brake symbol was turned on. From that point on, the brake light would only shine sometimes. leading me to believe there must not have been something wrong with the car, since nothing else happened after that. 2024 is when the red brake light and ABS symbol both lit up. The only information that I could find in the manual was to take the Prius to the Toyota dealership. I could not find details on the problem. I continued to drive the car regardless because there seemed to be no problem. After letting the car sit for a few months in 2025, I began driving it again, and it was fine. A month later, I turned on my car and was met with a loud beep that did not end. This was my final sign to take it to get repaired. The car has exceeded 200,000 miles. This fix is $3,205.40 at the dealership. My 2007 Toyota Prius is valued between $2k to $4k. The repair would cost more than simply buying another Prius.

Check engine light came on with codes C 1256 & C 1300. Primary issue is Brake actuator failure. Toyota is ignoring this known and repeated issue and it may lead to a dangerous/ deadly situation if brakes go out while driving.

There is a known, (by Toyota), issue with the ABS brake actuator in many Prius generations including the 2nd generation Prius that I own. My mechanic said it would cost @$3000 to fix. This as I said is and has been a known issue with these cars that affects the ABS braking and puts myself, my family and any one on the road near me in danger. Toyota was quietly replacing these under an unadvertised, extended warranty program. Mine is out of this so called warranty period but if this was a known issue and was corrected at no cost due to the fact Toyota knew there was an issue why was there never a recall on the affected models all with this same problem? I feel that this dangerous problem should be corrected by Toyota at no cost to the owners of their dangerous affected vehicles.

Brake Actuator system (ABS) needs to be replaced with only 133K miles on my 2007 prius. I heard a sound and had a Toyota service center check for any issues. They told me it was the ABS system that needed to be replaced at a cost of $5K. The repair costs are greater than the car value. Toyota knows about this year, make, and model issue. I contacted Toyota Corporate about this this week and learned there was an extended warranty for this specific issue on my car. They refuse to honor the extended ABS system warranty even though I'm under 150K miles per the warranty. They told me a letter was sent to me about replacing it at no cost in 2017. I never received the letter nor did the Toyota service center I used at the time tell me about the issue. Additional Info: I am not driving the car since the dash lights have come on - red triangle, check engine, VSC and (!) symbol - with a circle inside the (). Noise checked at Toyota dealer service center and confirmed it's the brake actuator system No inspection by the manufacturer, police, insurance rep, or others The sound came first when pressing the brake pedal and then the lights came on after taking to the service center

Due to water infiltration from a poorly manufactured hatchback, water is able to get inside the "Supply Assy, Brake Control Power" module in the trunk of the second generation Prius. This part ultimately shorts out and fails causing a loss of regenerative braking and a "brake warning light". Toyota seems to be aware of the problem as a replacement module is now sold in a "water proof sheet" (see attached). Toyota has also moved this module to a different location (away from the rear wall of the Prius) in other hybrid vehicles (such as in the Camry where it has been moved forward). I wonder if the hybrid batteries in the Prius also fail due to water infiltration in the rear sections of these cars.

Toyota has admitted that their BRAKE ACTUATOR assembly on their 2007 Prius FAILS and they will fix it for no charge BUT ONLY IF YOU COMPLAIN. The brake actuator on my 2007 Prius is now failing and the braking system has become UNRELIABLE and UNSAFE. Toyota should replace my failing brake actuator with a new unit for no cost because this is a SAFETY ISSUE. I refuse to pay $3000 out of my own pocket to repair an item which has a long history of FAILING.

The contact owns a 2007 Toyota Prius. The contact stated that while driving the speed was unknown due to the instrument cluster being inoperable. On another occasion while driving approximately 45 MPH, the brake pedal was depressed but failed to operate properly; however, on that occasion the instrument cluster was operating as designed. The vehicle stability control, ABS, and brake light warning lights were illuminated. The vehicle was taken to an independent mechanic and diagnosed with an actuator and brake booster failure. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 203,202.
