Brake pedal became hard and vehicle was difficult to stop. ABS warning light appeared on dashboard. This is a problem that Toyota has addressed previously by extending the warranty period to 10 Years/150,000 miles. My vehicle has 122,000 miles on it but the 10 year extended warranty has expired. I took the vehicle to a local repair shop and they confirmed that there was a problem with the brake actuator assembly. Now, Toyota says it would cost over $3000 to remove and replace their already defective part.

Incident Summary: While relocating from northern to southern Alabama, I experienced a sudden and concerning failure in the vehicle’s braking system. While driving, multiple dashboard warning indicators were triggered simultaneously, including: •Brake warning light •ABS light •VSC (Vehicle Stability Control) light •Additional system fault alerts This happened unexpectedly and severely impacted my ability to drive the vehicle safely. Given the nature of these warnings and the critical systems they pertain to, I immediately took the vehicle to a certified Toyota dealership for diagnostics and repair. Following inspection, I was informed that the ABS actuator and related components had failed and would require replacement at an estimated cost of nearly $3,000. I was further advised that while this issue had been part of a previous recall or customer support program, that program is no longer active. Rationale for Cost Coverage Request: 1) Known Safety Issue: This ABS/VSC failure aligns with prior technical service bulletins and recall actions issued by Toyota for Prius models of this era. The abrupt system failure while driving raises significant safety concerns. 2) Purchased from Certified Dealership: The vehicle was purchased from an authorized Toyota dealership. I trusted that all known recall issues would have been properly addressed prior to sale. 3) Recall Program Timing & Fairness: The original recall or warranty enhancement was tied to a timeframe or mileage limit, but given that this issue has not been resolved and is now manifesting as a serious failure, I believe an exception should be made—especially since it was known to affect vehicles like mine. 4) Customer Loyalty and Safety Assurance: I have maintained this vehicle responsibly and expect Toyota, as a brand committed to quality and safety, to assist with this issue in good faith. Request: I respectfully request that Toyota cover the full cost of diagnosing and repairing the ABS system issue.

I recently took my vehicle to the dealership because all the hazard lights on the dash came on. They diagnosed it as an issue with the inverter water pump and suggested that the engine was overheating, which was causing the hazard light to appear on the dashboard. So I had them replace that part and everything was fine. A week later, I went to drive to work and my entire dashboard was out. My radio, clock, blinkers, and brakes worked, but I could not see the speedometer, gas gauge, odometer or any other dashboard features. When I tried to restart the car, it wouldn't turn off. I tried several times and even got my husband to try. When we couldn't turn it off, I drove blindly straight to the dealership. They diagnosed the issue as being a problem with the combination meter. Recently, I found out that there was a Customer Support Program through Toyota that replaced the combination meter in my same car model. This service expired in 2017. I got the car in 2020-21. Thankfully I was home, and was able to follow my husband to the dealership. I'm not sure what I would've done if this happened while I was out. I am also have traction issues with the brakes. When I try to brake on a slope or incline, the glide hazard lights come on. It's happened several times when it's raining, but it's been happening more when it's not. I typically give enough space between myself and the car in front of me, but it's concerning that the brakes lock up when I'm on any type of sloped surface.

Brake actuator fails. Subject to prior recalls, but they're continuing to be an issue. This vehicle, and thousands of others like it, the electric brake actuator/pump starts running constantly then fails entirely. When that happens, as has to mine, the vehicle has NO power brakes, which can and does cause the vehicle to crash. The replacement part is over a thousand dollars. Toyota has engineered a failure mode that creates massive continuing profits.

The error lights related to the ABS, VSC braking system can suddenly come on, the antilock brakes stop working, and breaking power is greatly diminished. This occurs without warning and when it does, the brakes do not work safely and it is more difficult to bring the car to a stop. I have taken the car in to repair shops who have confirmed the issue. This malfunction produces error code C1256 and multiple mechanics have confirmed it is related to a faulty ABS Actuator Assembly and recommend immediate replacement of the unit. This is a common and known issue with these cars. I have been quoted a range of $2,100+tax to $2950+tax to perform the repair using a brand new part from Toyota.
