Recalls on the 2014 Toyota Prius V
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.

The contact owns a 2014 Toyota Prius V. The contact stated that the vehicle was previously involved in two car crashes, where the vehicle rear-ended other vehicles due to the brakes failure. The air bags did not deploy. A police report was filed after the second crash, but the information was not available. The contact stated that the other driver sustained unknown injuries during the second crash. The vehicle sustained damages and was repaired. There was no further information provided. Additionally, the contact stated while driving at various speeds and depressing the brake pedal, the brakes made an abnormal sound and the brake pedal was spongy. The contact stated that the vehicle hesitated to respond. The ABS warning light and several unknown warning lights were illuminated. The vehicle was taken to the dealer, where it was diagnosed that the brake booster had failed and needed to be replaced. The dealer informed the contact that it was a known failure; however, the repair could not be covered because the vehicle had a salvage title. The vehicle was not repaired. The manufacturer was notified of the failure and a case was opened. The failure mileage was approximately 120,000.

I was parked in my driveway and put my 2014 Toyota Prius in reverse to back up and park in front of my late husband’s workshop about 15 ft. away,on Oct. 10, 2022. The car sped up so fast I could not brake fast enough (no warning).It stopped when it hit the large door of the workshop, and damaged it and the back of my car, costing about $2,000 to the car. I contacted my insurance agent right away, and the person above him at the company the next day, as well as the service manager at the Toyota dealer where we bought the car at the end of 2014. I expect an increase in my premium from my insurance company. I’ll take it to Toyota when it’s done at the auto body shop, but I don’t expect any flaw to be found b/c that is what happened when I had the same kind of accident with this car in Jan., 2022, when I put the car in reverse to back down my long driveway, (which I’d done many times before),and it sped up so fast (SUA) that I couldn’t stop it (no warning). It hit a maple tree in my yard, and it cost about $12,000 to fix the back of my car. I was not injured in either accident, but this flawed accelerator could have caused serious injury to me or others, as it has in many documented accidents in the last 20 years. From the reports I’ve read since my accident last week, thousands of people have experienced similar or worse accidents from a Sudden Unintended Acceleration in their Toyota vehicle. Also, I read in an excellent well-researched and independent report that NHTSA has not researched the accelerator problem thoroughly and has remained noncommittal as to its possible flaws. Toyota wanted to take the “black box” from my Prius in 2022 after my accident, but I didn’t trust them to take it, and tried hard to find an independent engineering group with advanced degrees to study it and identify the flaw in it. I will try again to find such a group. The floor mat was NOT an issue at all—it’s the original one, stuck to the floor about 4” from the accelerator.

Hi my name is [XXX]. Toyota headquarter case # [XXX] Incident day July 6, 2018 I had a big technical problem with my 2014 Toyota Prius V where it caught on fire because one of the valve lifters fell into the engine head and broke the engine block while driving. When that happened, the oil began to leak into the muffler and the engine and hybrid wiring immediately caught on fire. Many of my colleagues who also bought the same vehicle for Taxi business use in San Francisco all have a similar issue as mine. A few of theirs caught on fire, and a few others mentioned to me that the head gasket for their same Toyota vehicle blew out and each of them had to replace it at around 120,000 miles. I believe that’s why they don’t manufacture these same vehicles anymore because of the defectiveness in the engine. I opened a case with Toyota Manufacturer back in July 2018 and they sent a specialist to inspect the vehicle after the fire. He found the piece that fell inside the engine and that damaged the engine. The Toyota specialist admit to me that the engine of my 2014 Toyota vehicle is very defective and must be covered under warranty. My mechanic replaced the engine for me with a used one with 28,000 miles. This entire case was documented under my name with Toyota Motors Manufacture. I contacted the highway safety and I tried to file a claim against Toyota at the time, but I never got a follow up on my case after I left various messages. All they said was that they will investigate but never gave me any information regarding the engine fire situation or honor any warranty. I hope this incident will be investigated by your department and have this vehicle under recall. Thank you.

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.

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.

SERVICE BRAKES
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.

Upon inspection, our mechanic determined that the master cylinder assembly and the actuator assembly require replacement (error code C1391). It is currently available for inspection, but will need to be repaired soon. Our safety and the safety of others is at great risk, because there is impending brake failure if driven and the end result could be catastrophic. On 09/13/25, the BRAKE, TRACTION CONTROL, ABS and ((!)) lights came on about 10 minutes from home. We drove home, parked the car and did not drive it again until we took it to our mechanic on 09/15/25. During this incident, the brakes failed to respond properly, which could have led to a serious accident. We took the car to a local mechanic and repairs are currently pending. The estimated cost for the necessary parts is approx. $3,000 and the labor costs are estimated to be between $1,100 and $2,000. Our local Toyota dealership was also contacted and they confirmed the presence of code C1391. Please reference Toyota Service Bulletin POL18-03, which addresses issues related to the braking system in certain Toyota models, including the Prius V. This bulletin indicates that various brake system-related warning lamps may illuminate due to internal malfunctions within the brake system, and it outlines affected parts that may require replacement. Additionally, please reference Toyota Customer Support Program 20TE07, which provides extended coverage for certain brake system repairs. It is concerning that, despite this well-known, very serious problem, Toyota has not issued a recall. While our vehicle currently has 116,975 miles, we are aware that the warranty period ended 10 years from the first date of use or 150,000 miles. However, this malfunction not only endangers our safety, but also that of other drivers on the road. We urge the NHTSA to investigate this matter thoroughly and consider the implications for a potential recall for this model, because Toyota is well-aware of this issue.

Toyota has a break issue that they extended the warranty for 10 years or 150000 miles and now a few months pass the 10 years I have a problem with the actuator giving warnings and my daughter went into a skid when applying the breaks. She was lucky and didn’t hit anyone. If Toyota knows there is a problem that is a safety concern they should fix it I did get a Toyota dealership to give an estimate to fix it and was told $4300.00 I think that’s too much for a defective part. It should be a safety recall.

ABS Brake pump actuator booster failed. It is available for inspection. While driving, I started hearing a hissing sound from my brakes. I tried to slow down and my several diagnostic lights (ABS, traction control, brake, check engine, etc.) flashed on while my brakes failed to work properly. I turned on my hazard lights immediately. I was in the middle of the road with my toddler in the car and I almost rammed into the car in front of me. Luckily I was able to pull into a turn lane and pushed with all my might on the brakes and it finally was able to stop. My brakes failed and I could have hit the cars in front of me and hurt my child, myself and others. It was terrifying. Problem has been confirmed by an independent service center. The warning lamps only appeared WHILE the issue was happening and my brakes failed to work properly.

I am reading that these vehicles have intelligent power modules in the hybrid inverter that fail and can cause stalling.

While braking on the interstate, this car threw error code C1391: Abnormal Leak of ACC PRESS. This is the brake system accumulator pressure - meaning lost all assistance to braking - it took a long time to slow down and come to a stop. Easily could have caused a serious crash had I been on a hill or coming up on stopped traffic. I did some research and found this is a KNOWN ISSUE with Toyota and SHOULD HAVE BEEN A RECALL! Toyota skirted the issue by offering customers that encountered the problem a CUSTOMER SERVICE PROGRAM where they would pay for a new brake pump and master cylinder. HOWEVER, Toyota put TIME and MILEAGE CONSTRAINTS ON THE PROGRAM, and it just so happened our car had exceeded those limits - so we had to pay full price for the repair of the 2 new brake parts - over $3,000! The 2014 Toyota PriusV that we bought new and had always serviced it properly was hardly worth that, but it was our only car, so we paid it. BUT will never buy another Toyota now - and NHTSA needs to fine Toyota for this poor brake system

Thankfully no-one was in front of me at the light and I was able to pull into the nearest gas station having to ram brake to fullest extent to get the vehicle to stop moving. All lights within the braking system lit up including the Master Warning Light, Brake System Warning Light, ABS Warning light, and SLIP indicator as well as the warning siren. These warning lights did not come on til after* the brake system was engaged with failure*** NOT PRIOR. It was not indicative of an issue prior too, no former brake issue or warning lights. I turned the vehicle off and then back on again to see if the same lights still lit and issue was still malfunctioning. I called for a tow and had vehicle taken to the Adams Toyota Dealership (MO)The following diagnostic code C1391 was registered on my vehicle at dealership. Upon research (not disclosure) I found that the above code- C1391- "Brake booster and Brake Booster Pump Assembly" is a known issue that Toyota offered a Warranty repair from May 21-Nov 22' IF FAILURE Not a recall but a "if" brake system fails. Please see Customer Support Program 21TE01. I purchased vehicle in OCT 21 and was never informed, never provided this warranty letter, issue didn't show up on Carfax etc and I purchased directly from the Toyota Dealership. Upon research you will find that Toyota is currently in class action and individual lawsuits re this specific part failure with the above diagnostic code. They are denying replacement due the expired warranty time. The Parts should recalled* not just a "warranty issue" -unacceptable to leave buyers uninformed to such a major issue that can cause accident/death (IM PREGNANT I MAY ADD!) and unable to seek covered repairs unless it fails!
