Brake Actuator and ABS Accumalator failed. It is a common failure reported by multiple owners on these cars. I was on the high way going 70 when it failed and lost any brake boost I had putting me in a very dangerous situation where I narrowly avoided an accident. Upon scanning the car's codes I got code C1391 which I looked up and saw a bunch of other people who were also struggling with this issue.

I purchased my 2015 Prius C in July of 2016. Since then I have consistently had issues with the lock actuator going out on various doors. As follows: 3/12/18 - Driverside 6/13/18 - Passenger Front 8/3/20 - Driverside 8/5/22 - Rear Driverside 12/16/22 - Passenger Front 3/14/23 - Driverside and now in July of 2025 the Driverside actuator is failing, AGAIN. The previous times were covered by my warranty, but that ended in 2023. My car is also kept in a garage. The dealership attempted to blame this issue on the elements, but come on...if that was the case, this would be happening to all sorts of various cars, and it's not. This is an issue for a variety of reasons, one being I am unable to access getting into my vehicle with the door lock that is not working. I currently have to go to my passenger side and crawl over to unlock my driverside door. If I needed to get into my car quickly, I would be out of luck. This is RIDICULOUS as this is the SEVENTH time a lock has gone out - making it about every year and a half that a lock needs to be replaced - and the 4th time for my driverside. How is this not a recall issue???

Recently the dash board lights started intermittently coming on. When they are on, the brakes do not work until pressed all the way to the floor and even then the car takes a long time to stop. The lights will randomly turn off and suddenly the car brakes work normally again. It is happening intermittently with no rhyme or reason as to when it will happen. It's scary to drive because I dont know if the brakes will work or not and I almost ran into another car when trying to stop at a stop light. I took the car to be inspected at the Toyota service center for $190 and after inspection they said the brake booster and master cylinder assembly need to be replaced and it will cost $2300.

We were driving on a city street about 25-30mph and the car jerked suddenly and the lights on the dashboard illuminated and the "Check Hybrid System" message came up as well. The car was able to coast to a nearby parking lot. We attempted to drive the car home and the car stalled in the middle of the street. We were able to push the car off the road and then get it towed. The presented a potentially very dangerous situation as the car had a complete failure while driving in the middle of the road. The Toyota service department ran a diagnosis which returned DTC P0A94. All of this indicates that the car should be covered under the CUSTOMER CONFIDENCE PROGRAM 23TE03 however that program seems to only cover the 2010-2015 Prius and 2011-2017 Prius V models and not the Prius C. There are several reports of this same issue happening on the Prius C as well though so it doesn't make sense that it is not covered.

I am writing to express a complaint regarding the issues I have experienced with the brake system of my Toyota Prius C, 2012 model. For the past several months, I have noticed that the brakes exhibit strange noises, soft pedal sensation, reduced braking efficiency, were driving and the ABS, traction, brake, and that other light turned on and the brakes became slow these issues have been observed on multiple occasions and pose a safety risk to myself, other drivers, and pedestrians. I have taken the vehicle for inspection, but the problems persist or have not been definitively resolved. I believe these faults may be related to defects in the braking system, and therefore I request a thorough inspection and necessary repairs at no cost, considering that the manufacturer could be responsible for manufacturing defects.

My 2014 Toyota Prius C experienced a complete hybrid inverter failure. The part number of the inverter is the same as the one covered under Toyota’s inverter recalls (such as Recall J0V), yet my VIN is not included. The failure created a serious safety concern, as the vehicle lost power while in motion. Toyota’s recall appears to be too limited in scope and may need to be expanded to cover Prius C models that share the same faulty part. I am requesting that NHTSA investigate this issue, as it appears to involve the same hardware defect acknowledged in other Prius models.

There was a driver side collision and the airbags did not deploy. Brakes do not slowly apply they slam down causing vehicle to slide/skid in emergency braking, ABS does not function properly. The dealership recently did an appraisal (4/2/25) on the vehicle that states “Lost communication with side airbag sensor LH, Side airbag sensor LH initialization incomplete, front speed sensor RH & LH circuit, and D- Door Motor ECU communication stop”. Insurance company inspected vehicle after crash, and there was a police report filed. There were no warning indicators prior to incident or after.

The brakes on this Prius started to make weird noises. Because it is a hybrid, I wasn't sure if it was normal. After searching online, it is a known issue. The car has just under 76,000 miles on it. It might be worth $7000 on a good day. Toyota wants to replace two brake parts, numbered 47050-52020 and 04006-74152 to a tune of $2700. According to a Toyota bulletin, this job should take 2.3 hours. For that amount of work, my local Toyota shop wants almost $2000 in labor. My car was seen by the local shop (being on an island, it is literally the only Toyota shop that this car can be seen) when the "customer support program" 21TE01 was in place and they did nothing. Now, the time window has disappeared, even though we only have half of the maximum number of miles to get the repair. Toyota should be ashamed of themselves.

My ABS actuator failed. Turns off the boosted braking and cruise control. This is a known issue in Toyotas and it always happens outside the warranty window. This is putting my safety at risk as the brakes don’t work as they’re supposed to

the vehicle exhibits several warning lights on the dash including ABS, VSC brake and handbrake. Diagnosed code as C1391 which toyota had released a bulletin to admit this issue, but they don’t make a recall instead of only repair it when occurred within their limited time line. now my vehicle falls in their bulletin scope but out of their “warranty “ scope. and quoted for thousands of repair. as a matter of fact, this put me at a great risk in driving it. and toyota didn’t make a public recall to solve this problem.

I was driving down the interstate with my cruise control on when all of a sudden the cruise control disabled and warning lights came up on my dash board. It still drove fine for several weeks. On Friday December 6th, I was going down the road and had to press the brake slightly for a car turning. When I pressed the brake, the car went into a spin. It spun a couple of rotations. Luckily I was on a wide part of the highway and no oncoming cars were approaching. Toyota had a recall for the same code and parts for the 2010 Prius but did not include the 2012 Prius. They just had an alert which I did not receive because the notice went to the former owner. However, I did take my car in for oil change and diagnostic but they did not tell me that there had been a problem with these parts. They want almost $4,000 to repair it. Why would they not include ALL vehicles with this same part. If it fail on one, it will fail on another. I think Toyota should make them all good. Please make them issue a recall for all of these parts. I took my car to a mechanic but because of special tools needed, you have to take your car to the dealership for repairs. When I called the dealership, I was told I needed a break booster pump and a brake master cylinder for a total of $3, which is ridiculous on a $7,000 car.

- #11614548September 14, 2024SERVICE BRAKES, ELECTRICAL SYSTEM, STEERING
Immobilized failure due to combination of brake hose failure preventing hybrid control/shift actuator. Hybrid steering lock became disengaged and could not communicate with the certification ecu due constant power being disabled due to complete main body failure. Hybrid system cannot go back into park however ecm side did. Ecm was not receiving power as dealer coded main body as a plug in hybrid effectively disabling fuel systems (including emissions/fuel safety) causing full misclassification in the smart key certification process. Car starts, goes into ready and disables LIN comms alongside cutting main relay due to tailgate and fuel constant powers being cut while driving.

Driving on the highway at 70mph my warning lights for my ABS, traction control, and other brake related warning lights came on. My brakes became soft and hard to stop the car. Immediately brought to dealer who said that my booster accumulator was leaking and needed to replace both the accumulator and pump for over $3,500. This is a know. Issue with Toyota because they have a service bulletin that they wouldn’t honor because my car is more than 10 years old. This is a serious issue and someone is going to get badly hurt.
