The 2014TOYOTAPRIUS carries 261 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 45 crashes, 2 fires, 22 injuries, and 0 fatalities. For crash performance, NHTSA's New Car Assessment Program gave this cohort an overall 4/5 rating, with 4/5 front crash, 5/5 side crash, and 4/5 rollover scores derived from standardized barrier and dynamic tests.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2014 PRIUS is service brakes with 79 filings, followed by electrical system (30) and unknown or other (23). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 3 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.
NHTSA currently has 51 investigation files overlapping the 2014 PRIUS, and 1 remain open. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2010-2014 Toyota Prius and 2012-2014 Toyota Prius V vehicles. Excessive voltage in the Intelligent Power Module (IPM) within the inverter may cause the hybrid system to shut down, causing the vehicle to stall while being driven.
The brake booster/accumulator failed on my vehicle. This part was a common failure during the 2010-2015 production run so much so that Toyota extended coverage to replace. Mine failed recently beyond the warranty extension of 10 years/150k miles. My vehicle has only 108k miles and is 15 months beyond warranty. Toyota Corporate will not replace this vital part, despite the fact it was a defective design. I canât drive it any longer since I donât have the $4000 to make repair. Toyota Corporate has shown little concern despite this critical safety defect.
The slip notification, abs, and brake lights turned on while driving on the highway. The brakes then became very stiff and the vehicle did not brake as fast or as well as it normally does without the lights.

On Jan 5, 2026 I was driving locally at about 40-45 mph. All of a sudden 3 indicator lights came on ABS, Brake, and Brake System Warning Light. There were no noises, but the brakes felt different. They did stop when needed. I left space between myself and others just in case, did not want an accident. Called my regular mechanic. They advised to not drive the car, but to bring it into the shop at 8am the following day. On Jan 6th, the mechanic stated it was beyond their expertise. It was towed to the local Toyota Dealer for repairs. It ended up being the Brake Booster and Pump. Upon investigation online, we saw this was a recall, but we were not notified by Toyota.

I was driving on the freeway, and a few lights(including ABS, brake lights) all came on and a beeping noise started, as i immediately lost complete control of my brakes! That God it was late, and no cars were in front of me. The car slowed down as I removed my foot of the gas right away. I tried to pull over as soon as I heard the lights, and thatâs when I realized my brakes were completely gone! I was able to stop after about two miles; car stop on its own as it slowed down. Apparently, this was a major known issue and had warranty up to 150k miles. At the time of the incident, my car had about 165k miles. I had the car for years, and no one at the dealer ever mentioned anything about this or even tried to make me aware of it! I called the Toyota dealer and corporate number several times and they declined providing me with any help at all! This caused me fear and traume because I never thought this was possible! It couldâve ended my life and the life of people around me if there w
Hello, We were informed that the vehicle paint had a recall due to paint chipping. Unfortunately we never received the notice and was unaware until after the recall program had ended. We are contacting you now to see how we can address this issue as our vehicle paint is chipping all around the car.
The brake booster system (electric brake booster pump) in my 2014 Toyota Prius has been making frequent, audible cycling noises inside the cabin, particularly during cold weather. I have also noticed a faint odor outside the vehicle that seems related to electrical movement. No ABS or brake warning lights have illuminated, but the cycling pump may indicate increased stress on the brake system. The issue has not yet been diagnosed or confirmed by a dealer or independent service center. The problem has not caused a loss of braking ability to date, but the unusual noises and electrical odor suggest potential risk if the booster were to fail completely. No recall or customer support program currently covers this issue. The component is part of the vehicleâs brake system and would be available for inspection by a dealer or manufacturer upon request. Toyota has offered no help or possibility of Goodwill assistance inspection for this issue.
The brake system malfunctioned suddenly. While driving and while stopped, the brake pedal became very hard and braking behavior became unpredictable. The vehicle sometimes brakes aggressively and other times requires excessive pedal force to stop. The ABS and BRAKE warning lights illuminated. The vehicle no longer provides normal braking assistance. This issue is related to a failure of the brake actuator / brake booster, which is a known issue affecting Toyota Prius models from 2010 to 2015. This defect creates a serious safety risk, as braking performance is inconsistent and may increase stopping distance or cause loss of control during emergency braking situations. The vehicle has not been repaired yet because the cost is very high and the manufacturer has declined assistance despite this being a known safety-related defect.

My 2014 Toyota Prius (VIN [XXX] , 77,000 miles) displayed Brake, ABS, and Slip warning lights. A mechanic confirmed failure of the Brake Booster and Pump Assembly (DTC C1391). Toyota previously acknowledged this as a safety-related defect under Customer Support Program ZJB, but my coverage expired because I never received Toyotaâs notice dated May 21, 2019. My car has been undrivable for weeks and Toyota refuses goodwill repair. This is a serious brake safety issue that should be reviewed for recall or extended coverage since many Prius owners have experienced the same failure.

The ADS, traction light, and brake light all came on at once. Apparently this is a known problem with these cars and Toyota was fixing them for awhile but has stopped. No brake issues were reported when I brought it in for inspection in 2023. I never received any mail stating that this was a know defect and I needed to bring my car in to get it inspected. It's obvious to me that Toyota designed a defective part that impacts safety, and is forcing the owner to bear the cost of the fix by creating parameters that can never be met before the warranty expires.
My brakes consistently lock and the car lunges forward. Driving down the highway I tapped my brakes and they didnât work. I lost traction in the brakes. I had no control over the car or speed. Iâm scared everyday I have to drive it. This is extremely dangerous and I've seen this comment often with this vehicle. Toyota said they had an extended warranty for this but it expired. I never received any mail or phone calls stating that this was a known defect. They say they canât do anything now and are quoting me over $3000 to fix it.
The brake actuator failed, it can be available for inspection anytime. My ABS light, brake light, and traction control lights all came on to indicate the failure. Since the hybrid engine requires the breaking system to recharge, failure of this part will eventually lead you to be stranded if it isnât functional. Additionally, the responsiveness of the breaks makes driving at higher speeds a lot riskier. Toyota offered an "extended warranty" to have the parts replaced for free for 10 years or 150,000 miles, whichever came first. My make is 2014, at only 89,000 miles.
The contact owns a 2014 Toyota Prius. The contact stated that the ABS and the traction control warning lights were illuminated. The vehicle was taken to the dealer to be diagnosed, and the contact was informed that the brake master cylinder needed to be replaced. The vehicle was not repaired. The vehicle was taken to a certified mechanic and was diagnosed, and it was determined that the brake booster had failed and needed to be replaced. The vehicle was repaired; however, one day later, both warning lights returned. The vehicle was returned to the mechanic and air was blown into the hydraulic valves and the other valves were cleaned; however, the failure persisted. The manufacturer was not informed of the failure. The failure mileage was approximately 150,000.
