- HYBRID PROPULSION SYSTEM: INVERTERCampaign 20V369000 · 24/06/2020
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2013-2015 Prius and 2014-2017 Prius V vehicles not included in recall 18V-684. 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.
Risk: An unexpected hybrid power system shut down may increase the risk of a crash.
Fix: Toyota will notify owners, and dealers will perform a software update for the hybrid system. If the vehicle has experienced an inverter failure with certain hybrid system faults related to this condition, the inverter assembly will be repaired or replaced, prior to software update. All repairs will be performed free of charge. This recall began July 24, 2020. Owners may contact Toyota customer service at 1-888-270-9371. Toyota's number for this recall is 20TB10 / 20TA10.

This vehicle has 95k miles, now the vehicle has a brake problem which can cause deadly problems. The parts that have gone bad on this car are defective parts that toyota knows about. The warranty they extended for this ended in 02/2015. They had 150k miles or 10 years limit on that warranty. We are well under the mileage and 10 months over according to toyota. Can’t believe they will dismiss something this delicate and dangerous. The parts are not cheap and it’s something we can’t afford to fix right now. I can’t believe Toyota will just wash their hands on something this important in a vehicle. This is a know defective part! They should have some sort of responsibility and resolution. I called and was told they cant do anything. Even a part offer so we can fix nothing. Please review this and hopefully you can help.

The vehicle has 95k miles on it and both brake actuator assembly and booster pump have gone bad. This is a defective issue, I called toyota and was told too bad since the program that fixed this ended 02/25. The car met the mileage requirement, but being 10 months out of the date gives toyota the right to wash their hands on a defective part. The part is over $1500 just in parts to replace! This is wrong on their part. Not one option offered.

On the morning of December 11th, 2024, the brake system warning light (ABS, yellow) illuminated on the dashboard along with the red BRAKE indicator and the yellow Vehicle Stability Control (VSC) system light. I consulted a mechanic who performed a computer diagnostic and informed me that the ABS module booster had failed. He said that will order the part to change it but meanwhile he advised me to drive more cautiously and maintain a greater distance from the vehicle ahead, allowing extra space for my car to stop due to the increased braking distance caused by the failed ABS module booster. Later that day, at approximately 5:30 PM, I was driving home in heavy traffic, with speeds not exceeding 40 miles per hour. The vehicle in front of me began to decelerate abruptly. When I applied firm pressure to the brake pedal to slow down my car, it lost all control. The vehicle began to skid, with the amplitude of the skid increasing progressively. It struck the highway guardrail on the left, changed trajectory, crossed all four lanes to the right uncontrollably, and ultimately collided with the highway guardrail on the right side.

THE DRIVER CANNOT SEE ANY PART OF THE FRONT OF THE CAR. IN MOST CARS, THE DRIVER CAN SEE ENOUGH OF THE HOOD AND FRONT FENDERS TO JUDGE HOW CLOSE THE CAR IS OTHER OBJECTS (CARS, WALLS, PEDESTRIANS, ETC.), BUT IN THE PRIUS, EVEN THOUGH I AM OVER 6 FEET TALL, I CANNOT SEE ANY PART OF THE HOOD OR FRONT FENDERS. WITH THAT LACK OF PERSPECTIVE, I SCRAPED THE LEFT FENDER AGAINST A PARKING LOT WALL. BUT THAT SAME LACK OF PERSPECTIVE COULD RESULT IN HITTING A PEDESTRIAN.

THE TRANSMISSION GEAR SHIFT IS DANGEROUSLY DESIGNED. THE SHIFTER WILL MOVE INTO A GEAR POSITIONS EVEN IF IT TRANSMISSION DOES NOT ACTUALLY SHIFT INTO THE GEAR. WHENEVER THE HANDLE IS RELEASED, IT SPRINGS BACK TO THE CENTRAL POSITION, WHETHER THE TRANSMISSION IS IN GEAR OR NOT, SO THE DRIVER DOES NOT KNOW IF THE TRANSMISSIONS IS ACTUALLY IN GEAR OR NOT--OR IF IN GEAR, WHICH GEAR. THE DRIVER IS EXPECTED TO LOOK AT THE INSTRUMENT PANEL SO SEE WHAT GEAR IS HIGHLIGHTED IN THE DISPLAY. I RENTED A PRIUS FOR A WEEK AND NUMEROUS TIMES, I THOUGHT I HAD SHIFTED INTO DRIVE (OR REVERSE), BUT WHEN I PRESSED ON THE ACCELERATOR, NOTHING HAPPENED BECAUSE IT HAD NOT GONE INTO THE SELECTED GEAR, AND I DID NOT KNOW THAT BECAUSE THE SHIFT LEVER ALWAYS SPRINGS BACK TO CENTER POSITION, WHETHER THE TRANSMISSION IS IN GEAR OR NOT. ONE TIME, AT NIGHT, I WAS MAKING A THREE-POINT U-TURN, SHIFTED INTO DRIVE, TURNED THE WHEEL TO THE LEFT, STEPPED ON THE ACCELERATOR, AND SUDDENLY THE CAR WAS TURNING TO THE RIGHT! PANIC'SLAM ON THE BRAKES. THEN I REALIZED THE TRANSMISSION HAD NOT SHIFTED INTO DRIVE AND I WAS ROLLING BACKWARDS. IF THE DRIVER FEELS THE SHIFT LEVER GO INTO A GEAR, THE CAR SHOULD BE IN THAT GEAR; IF IT DOES NOT GO INTO THAT GEAR, THEN THE SHIFT LEVER SHOULD NOT MOVE INTO THE POSITION; AND ONCE IN GEAR, THE SHIFT LEVER SHOULD STAY IN POSITION, NOT SPRING BACK TO CENTER.

I bought this vehicle on July 3, 2015. When I took it in for an oil change in Dec. 2015, I was informed that there was a mice infestation and that the electrical wires and other systems were damaged, resulting in about $2,800 in repairs due to the mice chewing the wiring. I just took this vehicle back in on 29 Nov. 2021 because some of the systems weren't working properly, and they confirmed that a mouse has again chewed up the electrical system, again costing about $5,000 in repairs. I've just been informed by my exterminator that Toyota uses a wiring harness coated with a soybean based coating which is causing reports of mice damage in a lot of Toyota vehicles. We have 2 other vehicles which are not Toyota vehicles and have never had a single problem with mice chewing the wiring harnesses of those vehicles, although all are parked in the same area. The vehicle is currently pending repairs at Fred Haas Toyota Country in Houston, TX and will be there for at least a couple of weeks pending availability of parts. Electrical issues of this type can cause serious failure of safety features. Toyota has never told me that they use soy based elements in their vehicles that would entice rodents to chew the wiring or otherwise entice them into the vehicle. I do not have a report from insurance yet, but I have filed a claim.

The brake accumulator went out thanksgiving day on my way home nearly causing an accident. I also missed dinner due to the issue creating a clearly unsafe driving condition where I was barely able to use my brakes. This is a known issue by Toyota, whom extended the warranty to 10 years. Of course, my warranty was 3 days past the 10 years even though it is under the mileage requirement. This should have been a recall, as it is a known and reported problem. I am now out 3300$ for the repair just to get my car in an operable condition. There were no warnings, the abs light as well as the traction alert went off and I lost the ability to properly brake in an instant. There was no warning, nor was I notified about this part.

There is a known brake booster issue with the Toyota Prius. They extended the coverage to 150,000 miles. My car is at 127,000 miles and they said the repair isn't under warranty and will cost over $3,000 to fix. There was no pre-warning lights or information received about this repair notice. I only noticed this when the lights came on and our ABS lights went out. When I took it in they said I missed the deadline by 5 days, that I would have had to let them know by 11/20/2024. Which is insane for such a huge issue when I am well under the mileage coverage.

Hi, I am reporting a brake system failure on my 2015 Toyota Prius. In July 2025, the ABS and brake warning lights suddenly appeared, and a Toyota service center confirmed it is the known Prius brake system defect. The repair estimate ranges from $4,502 to $27,814, but Toyota declined coverage because the vehicle is just past the 10-year warranty limit. This issue poses a safety risk due to reduced braking performance. 1) The brake system / ABS actuator assembly malfunctioned. and yes, the component is still installed in the vehicle and available for inspection upon request. 2)The ABS is no longer functioning properly, significantly increases the risk of losing control or extended stopping distance, especially in wet or emergency braking conditions. I rely on this car for daily transportation in a car-dependent area, so this issue directly affects my ability to drive safely and could endanger others on the road. 3)Yes. The issue was diagnosed and confirmed by an authorized Toyota dealership center. 4)Yes. The vehicle was inspected by an authorized Toyota dealership only. 5)Yes. The ABS light, brake warning light, and other dashboard indicators suddenly appeared in July 2025.

The Brake Booster system failed two weeks after the Toyota Customer Confidence Program for that condition ended and they will not reimburse me for a $3000 repair. I knew there was a problem because all the dash lights came on at once while we were driving on a highway. I had it towed away to be repaired and it was found that the brake booster system was failing. Had I ignored it or not acted as immediately as I did the brakes could have failed while the car was in use and hurt or killed me or someone else. They should issue a recall for this condition and fix it for Prius models that still need it and they should reimburse me.

The contact owns a 2015 Toyota Prius. The contact stated that while driving approximately 15-20 MPH, the ABS, brakes, and the traction control warning lights, and the malfunction indicator light were illuminated. Additionally, the vehicle hesitated to respond while depressing the brake pedal, causing the braking distance to be extended. The vehicle was taken to the dealer, where it was diagnosed with an abnormal leak in the accumulator and a leak in the brake booster pump. The dealer determined that the brake master cylinder and the brake booster pump needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 94,100.

The ABS, BREAK, and Traction Control, suddenly turned on when I was traveling on the freeway in mild traffic. I was traveling at about 60-65 mph. I attempted to use the breaks and could feel a substantial difference in how much and how hard I had to push in order to stop. The problem has not been confirmed by a dealer or service center. The vehicle was inspected by my brother in law who works on cars frequently. There were no warning symptoms prior to the problem. The problem first occurred on Saturday November 1st at about 12:30. According to my brother in law, it was the break pump that failed; you can hear air escaping when you push on the break pedal.

I was driving from Las Vegas to my home in Los Angeles. An alarming message began flashing on the dashboard telling me to pull over. The vehicle became hard to control. I somehow managed to get it off an exit. I was "lucky" enough to get it towed to a nearby Toyota dealership where I was told the inverter had failed and that that inverter and associated parts had to be replaced. On my 2015 Prius with only 50,000 miles on it. I SPECIFICALLY asked if there had been a recall on the electrical system of any 2015 Priuses, and they flatly said no. I also CALLED TOYOTA, and they also said there were no recalls involving the electrical system or inverters. The Barstow Toyota dealership said it would cost over $5,000 to repair AND that they wouldn't have the parts they needed for a WEEK. As it was, I had been stranded in the desert at a hotel for two days. I then had to pay $1,100 to be towed back to LA and took it to a hybrid mechanic I trust and paid them to do the work. But this cost me THOUSANDS UPON THOUSANDS. In a month where a friend of mine died (which was the reason I was driving from city to city). To have to replace this on a car with only 50,000 miles is preposterous. To NOW find out there actually IS a recall on the 2015 Prius FOR the electrical system involving the inverter is so far beyond frustrating, I don't have the correct word for it.

On or around 9/13/25 my ABS, Brake, Traction and Emergency Sign sensors turned on in my 2015 Toyota Prius. I noticed that my brakes became squishy and when I drove, it took longer for my car to brake (there was more distance in my braking ability to stop the car). My car also felt a bit more airy than it usually does when I drive it. I took it to 2 independent car repair shops for a diagnostic and both told me that the ABS C1391 code came up. Soon thereafter, I took it to a local Toyota dealership for a diagnostic and was given the ABS C1391(code) Abnormal Leak in the accumulator. The Toyota mechanic informed me that that when he did the diagnostic, the TSB 0024-19 code came up on his end, which means that Toyota alerts their mechanics of the necessary procedures to implement for this problem, as it's a known Toyota problem and defect: 1) Remove & Replace the Brake Booster Assembly w/the Master Cylinder (apparently the master cylinder goes out too since they're connected) and 2) Remove and Replace the Brake Booster Assembly Pump. Toyota's estimate to repair it is $4,404.72; I can't afford this and need a car. It's my only car! I did research and learned that this is a known Toyota issue for Prius (2010-2015) and a Customer Support Program w/an extended warranty was issued to cover the full cost. Despite this, their extended warranty expired for me on 12/29/24, despite me meeting the other 10 yr or 150K or less mileage criteria. Despite filing a complaint with Toyota's Resolution Center they refused to extend or offer warranty or any payment for a KNOWN Toyota defect, saying my issue was "after the extended warranty date" and there "isn't a recall." I'm disgusted to say the least about this, as Toyota is well aware of this car part defect which is a safety hazard and liability for its customers. Something must be done about this. It's unfair and not equitable to have loyal Toyota customers absorb the cost of known safety hazard defects by Toyota and risk lives.

Before, I was driving and occasionally the traction control light would flash when I put my foot down on the brakes but would go away when released. I didn't think much of it but then a few days later, I went to brake to stop the car and then the abs, traction control and brake system lights lit up on the dash and wouldn't go away. I pulled over safely and turned the car off and on again but it wouldn't go away. The brakes were also noticeably more firm compared to before as it was quite squishy but now it was solid and all regen braking went away and it appeared I had no more ABS which could lead to a collision. I immediately took it into the dealer to have it diagnosed. I did some reading and if I kept driving with this problem, eventually the brakes would fail and collapse completely and leave me unable to stop the vehicle. At the service center, they were able to read the code DTC C1246 and clearing the codes did not work. The part that was replaced was the brake booster and the brake master cylinder and the brake pedal stroke sensor. It appears that a warranty program exists for this issue but it is not a recall. I am also not sure if the part that was replaced is a revised part that will no longer have this issue or there is no change in the part design. I believe this is a massive safety issue and should be a recall and not a warranty replacement program as every prius should be recalled for this defect. I was very close to being out of warranty and if I had taken any longer to bring it into the dealer I would have been out of the extended CSP warranty. Even the dealer initially thought I would be out of warranty but I had to argue that I was in warranty and should be eligible for a warranty replacement and that I should not need to pay for a diagnostic fee despite it not being a recall.

Our 2015 Prius suffers from the Brake booster/master cylinder defect as outlined in TSB T-SB-0024-19. Which is a well known an pervasive issue for this vehicle. We were unable to medically drive when the vehicle was still under the time frame and mileage which would have allowed it to be covered by Toyota. Despite requesting an extension due to extenuating circumstances (medically unable to drive, thus detect the issue during the covered period) they disclaim any and all remedy. When I was able to drive the vehicle after being cleared from surgical recovery restrictions, the issue was immediately found and reported to Toyota whom promptly denied the claim through their local dealership and subsequently through their offices after sending a letter requesting an exception or good will extension. This issue is a major safety issue and unfortunately also a cost prohibitive repair to take on. The defect in question is acknowledged by Toyota through MULTIPLE TSB's and warranty extensions and their own ZJB Customer support program. We are under the actual mileage cutoff but outside the time frame by a few months (medical period where the vehicle was not driven).

I have a 2015 Toyota Prius with 48,600 miles. My breaks started failing suddenly while driving which almost got me into a car accident. I took it to my mechanic immediately and the DTC was Code C1281. I was advised to take the car to A Toyota dealer. I got an appointment and a manager was waiting for me wanting to charge me $250 for a new diagnostic test and $2,500 - $3,000 for repair if the diagnosis was correct. I called customer service and washed their hands from any responsibility. I called the Toyota's customer advocate service located in Plano, TX and was on the phone for more than an hour. They apologize, were very courteous, but I was told that I was not covered because I had call too late and that the repair offered by Toyota had expired. They acknowledged that Toyota never issued a recall for this manufacturer defect. I informed them that the discovery of the problem had occurred on [XXX], 10 years and 2 month after I bought the car from them and that the car was almost new with very little mileage. I let them know that felt this was a deceptive trade practice with breach of warranty and breach of implied warranty of merchantability, along with it being a fraudulent concealment with failure to warn their customers of potential danger and harm. I plea with the Toyota's advocate that since the statute of limitation and equitable tolling had not elapsed from the day of discovery that they should honor my request for it being just. I was told that Toyota's decision on the Prius brake defect was not covered and that I was free to take my car to a Toyota dealer or an independent mechanic, whatever was more convenient and/or affordable and that the cost was on me. I asked if I were to get a new Toyota car and trade in my old car if they would appraise it as if the defective brake part had not malfunctioned. The answer was that the value of my car if traded in, would be significantly less due this issue. He gave me a Ref # [XXX] and hanged up.

On XXX, I was driving my 2015 Toyota Prius with my family in the vehicle and approaching stopped traffic on dry pavement. An emergency vehicle was approaching from behind, so I began braking earlier than usual. When I applied the brakes, the vehicle did not stop normally. The front slowed/stopped while the rear of the Prius suddenly slid sideways toward the adjacent lane, bringing the rear passenger side dangerously close to another vehicle. Had I begun braking at my normal stopping distance, I believe a collision would have occurred. No crash or injuries occurred, but the incident was extremely dangerous. I drove the vehicle very slowly to Purrfect Auto Services, [XXX], where the brake/ABS system was diagnosed. I observed diagnostic code C1391. The shop has had the vehicle since XXX and has experienced repeated problems with used replacement brake-system components that were defective or would not function properly. The vehicle has remained unsafe to return to service while the shop works to obtain a properly functioning replacement part. I am reporting this because the sudden and unpredictable braking behavior created a serious risk to my family and other motorists. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On August 10, 2021 my 2015 Prius was parked in a Strip Mall parking lot. When I turned on the Prius and shifted into reverse, after traveling only a foot or so, the shift selector popped into Neutral. When I shifted into Drive, it happened again. After several tries with the same results, I called Findlay Toyota Service. I was advised to have the car towed, at my expense, to Findlay Toyota Service. Note: the tow truck driver reported to me and the Findlay Service Representative that he could keep the shift selector in gear by holding it in place with his hand while driving it to the tow truck. The Prius was left at Findlay Toyota for 2 days. The Service Rep reported that 3 different mechanics plus himself could not duplicate the problem; the Prius stayed in gear for them. I researched online and found other Prius owners reported this problem ocurring intermittantly. The only solution seems to be replacing the Shift Selector Switch at a cost of $838.35 + tax. Even though this is clearly a safety hazard, there is no recall.
