2014 TOYOTA PRIUS Complaints

The vehicle stalled while driving 35 to 45 mph. Engine had no power but the brakes and power steering worked.

2014 Toyota Prius C with 220k miles. Four warning lights came on while driving. Brakes became not responsive unless you press down very hard. Regenerative braking, went away. The Brake pump can be audibly heard turning on every few seconds.

While driving my 2014 Prius V it stalled. I turned it off and restarted it. The yellow car symbol with an exclamation point lit up. I turned the car on and off again. The light went away and I was able to drive home. I was unable to get any OBD 2 codes on my personal reader. I changed the 12 V battery and thought this had fixed the stalling. Then it stalled again and repeated the same process. Though we were able to drove the car I had it towed to a dealership for safety reasons. The dealership pulled codes, cleared them, drove the car 20 miles, and were unable to reproduce the codes. I was told to return when the codes returned. It stalled again and now I am afraid to drive this car.

After 120K miles and 11 years of use, my Prius 3 brake booster pump failed while I was driving. The warning lights came on, including the ABS and brake lights. My brake felt strange, and I had to finish my drive to the dealership keeping a large driving distance so the brakes would work in time. I was advised that this was a result of a C1391 error and that the brake pump part is only covered under extended warranty for 10 years. The advisors at the dealership said it is extremely common for cars to come in with this problem just after the warranty period has ended. I have spoken to other Prius user who have complained of the same issue and are considering a class action lawsuit because this safety issue is so common.

While driving my dashboard lit up with Brake, ABS, and traction control warning lights. Brake pedal fell to the floor when pressed. I was then able to stop the car. I brought the car to a local auto parts store, where they were able to determine that the error code was C1391 brake accumulator pressure leak. I made an appointment and brought my car to my local Toyota dealer the next day. I was informed that the brake booster assembly, brake booster pump, and master cylinder would have to be replaced, at a cost of approximately $4035.00. I was informed that Toyota issued a Customer Satisfaction Program for this exact issue on my car. While my car has 129,000 miles and falls within their coverage range of 150,000, the car’s age of 11 years did not fall within their limit of 10 years. According to Toyota, this is a known failure and my only problem is that my brakes did not fail sooner. Toyota’s corporate office denied my appeal to cover the cost of the repair. The local Toyota dealer charged me $150 to read the code and confirm what the local Auto parts store was able to do for free.

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.

Issue started with a noise sounding like a motor constantly trying to prime its self. Then while driving on freeway ABS light Brake light and traction control lights all came on. Took car to dealership and was given a $3700 bill to replace Brake Booster Master Cylinder and Brake booster pump. This is a known issue to Toyota and have offered an extended warranty 10 years or 150000 miles but not a recall. My vehicle is at 11 years and 123000 miles. This issue put my family in danger due to the threat of total brake failure.

Was driving down the road and the brakes stopped working and the the brake light the traction light and abs light came on. The brakes only worked if i put the pedal all the way to the floor after that. I checked online and found numerous other people have had this issue but no recall has ever been done. only nhtsa safety notices and a volunteered customer support program by toyota which was no longer being honored because I was passed the 10 year mark even though my vehicle was still under the 150k mile threshold by toyota. I wish your organization would force toyota to do a full recall on this. this is a dangerous safety issue involving a defective brake booster and master cylinder

The contact owns a 2014 Toyota Prius. The contact stated while driving at an undisclosed speed, the vehicle failed to stop or decelerate as intended while the brake pedal was depressed. The ABS and service brake warning lights were illuminated. The contact added brake fluid; however, the failure persisted. The vehicle was taken to a local dealer where it was diagnosed; however, the cause of the failure was not yet determined. The vehicle was taken to a local Auto Zone, where it was scanned with an OBD2 scanner and DTC: C1391; was retrieved. The vehicle was not repaired. The manufacturer was notified of the failure and the contact was informed that the failure was related to an unidentified Toyota Campaign; however, the warranty had expired. The failure mileage was approximately 92,802.

The brake booster assist assembly failed, causing a leak of brake fluid, im told that over time this failure can lead to a break failure. I contacted Toyota. They informed me that there was an assistance program for fixing this defect. However it expired in 2024? If they know about a defect why did the program expire? This is a safety issue.
