The Office of Defects Investigation (ODI) has received a petition dated September 19, 2023 from the owner of a 2012 Toyota Prius V requesting that ODI reevaluate its decision to deny DP19-004. In the letter, the petitioner reported experiencing an unexpected and complete loss of brake power while driving, accompanied by multiple dashboard warning lights. This petition is based on the petitioner's direct experience and assessment that ODI closed DP19-004 because its prompting petition was withdrawn by that petitioner.

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

HYBRID PROPULSION SYSTEM
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.
Risk: If the hybrid system shuts down unexpectedly, it can increase the risk of a crash.
15V449000
HYBRID PROPULSION SYSTEM: INVERTER
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain model year 2012-2014 Prius V vehicles manufactured August 22, 2011, to June 30, 2014. A component within the hybrid inverter assembly may overheat, causing the hybrid system to reduce output power allowing the vehicle to only drive a short distance. In some circumstances, the hybrid system may shut down causing the vehicle to stop while being driven.
Risk: The vehicle may enter a fail-safe/limp-home mode that limits the drivability of the vehicle. The hybrid system could also shut down completely resulting in a vehicle stall, increasing the risk of a crash.

EXTERIOR LIGHTING:TAIL LIGHTS
Genera Corporation (Genera) is recalling certain aftermarket replacement tail lights, model 11-6468-00 (driver-side), and model 11-6467-00 (passenger-side), sold for use on 2012-2013 Toyota Prius V vehicles. The brake light and tail light circuits are switched causing the brake lights to be illuminated continuously until the brake pedal is pressed, when the brake lights will go out.
Risk: The reversed tail lamp function reduces the ability to warn other motorists of the driver's intentions, increasing the risk of a crash.

AIR BAGS:FRONTAL:SENSOR/CONTROL MODULE-INACTIVE
Southeast Toyota Distributors, LLC (SET) is recalling certain models interspersed through model years 2009 through 2013 as follows: model year 2009-2012 Tacoma, 4Runner, Camry, Camry Hybrid, Prius, and RAV4; model year 2009-2010 Avalon, FJ Cruiser, and Highlander Hybrid; model year 2010-2013 model year Corolla, Sienna and Tundra; model year 2009-2013 Highlander and Venza; model year 2012 Prius V; and model year 2010-2012 Sequoia. During modification by SET to include accessories such as leather seat covers, seat heaters or headrest DVD systems, these vehicles may not have had the passenger seat occupant sensing system calibration tested. Without passing the calibration test, the occupant sensing system may not operate as designed.
Risk: If the front passenger seat occupant sensing system is out of calibration, the front passenger airbags may not deploy or they may deploy inappropriately for the passenger's size and position. This could increase the risk of personal injury during the event of a vehicle crash necessitating airbag deployment.

Recall 202172355,683 units in Canada
Electrical
Issue: This recall is for certain block heater kits installed on certain vehicles or sold as accessories at Toyota or Lexus dealerships. On certain vehicles, the engine block heater cable may not have enough heat protection and could be damaged by high temperatures. If this happens, the cable could short circuit while plugged in, and cause the wiring to overheat or melt. Note: This recall only affects the following block heater/cord part numbers: C014003034 PK5A408J09 PU14000904 C014003151 PK5A408J13 PU14000905 C014000885 PK5A489J11 PU14000907 C014000888 PK5A489J22 PU14000909 C014000907 PK5A410H00 PU14000911 C014100904 PU14000900 PU14000913 C014100907 PU14000901 PU14003571 C014100911 PU14000902 PK5A489J14 PK5A408J05 PU14000903 Safety Risk: Engine block heater wiring that overheats or melts could create the risk of a fire. Corrective Actions: Toyota recommends that you should stop using the engine block heater immediately. Toyota will notify owners by mail and instruct you to take your vehicle to a dealer to disable the engine block heater. For some vehicles, the corrective actions for this recall are under development. For others, a new engine block heater cannot be installed, and the owner will receive a refund of the purchase price of the engine block heater.
Recall 201854623,125 units in Canada
Powertrain
On certain vehicles, the Intelligent Power Module (IPM), which is part of the hybrid drive system, could become damaged under certain driving conditions. This could cause various warning lights to illuminate on the instrument panel of the vehicle and cause a reduction or loss of motive power, increasing the risk of a crash causing injury and/or property damage. Correction: Dealers will update motor/generator and hybrid control ECU software and affect repairs as necessary. Note: This recall supersedes recalls 2014-042 and 2015-312. Vehicles repaired under the previous recall(s) will require repair.

The ABS system has failed. All brake related warning lights have appeared on the dash board and the ABS no longer works. The car will brake for now, but the pedal is mushy. The issue was diagnosed by a dealer. The diagnosis from the dealer, based on diagnostic trouble codes they did not provide, is that brake fluid is leaking in the master cylinder and brake booster. The recommendation is to have both the master cylinder and booster replaced. This vehicle has 143,000 miles on it. No accidents have occurred as a result of the brakes yet but how long before the brakes ultimately fail is unknown.

ABS, brake, and traction control lights, all illuminated at once on the dashboard. Inspection found DTC C1391 indicating the accumulator is leaking or failing to hold pressure correctly. We are advised that the braking system performance will decline, eventually failing. An very expensive repair is required and Toyota apparently has a shortage of the parts required. We cannot drive the vehicle given the potential of braking failure and cannot get it repaired in a timely manner for lack of Toyota parts.

The power assist braking system failed while I was driving in the rain. I was approaching a stoplight and I had to push down a lot harder and farther than I typically have to in order to stop. Luckily I was not going that fast and there were no cars ahead of me, but I stopped beyond where I had intended at a busy intersection. No warning lamps or messages had been illuminated prior to this happening. After the failure, the Brake system, ABS, and SLIP indicator lights were on and remained on when the car was restarted. An independent service center used a scan tool and found code C1391 stored in memory, indicating that the brake booster is unable to hold pressure due to an internal leak. The vehicle has not yet been inspected by the manufacturer, police or insurance, but can be available upon request.

I bought this car over a week ago for a good price, performed fine until I’m driving it home on the interstate and some abs/brake lights came on the dash. I enter my city and notice the brakes aren’t performing as tight as they were during the test drive. A few days later I take it to a local dealership to get it looked at. The brake actuator and pump had gone bad, causing this issue. It cost almost $5,000 to fix there, I couldn’t afford it so I had to only pay the $185 for the diagnostic. It’s an on and off thing, sometimes the lights go away and it brakes as it should, but most of the time the lights are on and the brakes don’t work as they should. I fear one day the brakes may eventually give out on me and cause an accident. I am available for inspection.

While driving on the interstate I went to slow down to merge and my brakes failed. The following warning lights came on: Master Warning Light (yellow), Brake System Warning Light, Brake System warning light (red), ABS Warning Light, and the Slip Indicator light. My vehicle was towed to a Toyota Dealership and after running a diagnostic test, they confirmed that it was the "Break booster with accumulator c1391 stored internal leak of accumulator and need immediate attention" which they quoted at $4,295.68 to fix. After researching the issue saw A Customer Support Program 20TE07 was issued taking responsibility for the faulty Brake Booster Pump Assembly however only covered the repair for a two-year period and only if it was one of the identified diagnostic trouble codes listed in the CSP issued by Toyota but expired in Feb 2022. The code pulled from my vehicle 3 days ago was listed in this document, but the coverage only covers until Feb 2022. This is not a normal wear and tear issue, it is a faulty part that Toyota identified as a life and death safety concern but refuses to do anything about because mine didn't show an issue within their 2-year CSP timeframe. Toyota identified that there are roughly 118,950 2012-2014 model year prius V with a production period of late September 2010 to mid-November 2014 vehicles that this faulty part affects along with everyone else on the road with these vehicles as it causes failure of the brake booster pump assembly, which leads to a loss of braking assist and the deactivation of the Vehicle Stability Control system. For the safety and lives of the owners of these vehicles and all of the other lives of the drivers on the road that this could affect in the case of this faulty part should there be a catastrophic accident, like mine could have been, a nationwide recall on this part MUST be issued.

I didn't throw more money at the Dealer, and took off the panels to inspect the wiring myself. There was damage to the passenger side door harness wires. I removed the harness and ordered a $60 used replacement on Ebay. While waiting for delivery, I researched rat damage to Toyota wires, and how rats could possibly enter the interior of the car. I discovered that there is an UNSCREENED 12x9 inch opening to bring fresh air into the HVAC system. It is hidden under the windshield wiper cowls. Also, there are two UNSCREENED vents in the trunk area. Other Prius owners covered those openings with 1/4 inch metal wire hardware cloth.

While driving suddenly the ABS and vehicle traction lights came on and the car became very slippery, was unable to stop without an excessive amount of space between the car in front of me and me. While looking at the car, I realized the actuator brake booster pump. I then found multiple websites and forums dedicated to people with the same problem ( brakes suddenly not functioning correctly while driving) with the same model car as I have, and there was a service bulletin that shows Toyota acknowledged there was a problem ( and a fix) but with the date of the bulletin and the date it was to be fixed within, it was near impossible to actually have it fixed.

Anti lock brake malfunction. Code c1391 leak in brake accumulator. This seems to be a common code for brake issues with Prius. The cost to repair is significant, more than the value of the car.

The issue is my brakes failed on me all of a sudden. My abs light, traction control light, and brake light came on out of nowhere. Suddenly didn't have brake pressure. Had to pump the brakes a few times before the car would stop. Luckily I didn't hit anything or anyone. I brought the car to Prius specialist and they diagnosed it saying it was the ABS Actuator Pump Assembly and Master Cylinder. They said it is quite common in the 3rd generation of Prius'. I contacted Toyota North America and they said they had a recall on the parts but it ended Dec 31st, 2021. I bought the car in 2022 unknowingly. Was quoted around $4000 to repair it parts and labor. This is a safety issue that should not be limited to time. Luckily I was not on a Freeway or anywhere where I could have done damage. This issue is a hazard to myself and other people on the road. Toyota needs to resolve this.

I write to add my voice to the litany of complaints in support of NHTSA investigation DP23005. While on an road trip recently the ABS, Traction Control, and Brake warning lights all came on. The brake felt squishy and didn't seem to be functioning as confidently as before. I altered my driving (giving plenty of distance, lowering my speed) so that in the event the brakes quit working I would have an exit strategy. I took it to my Independent Service Center as soon as possible who found the code C1391 and diagnosed the need to replace the master cylinder / booster assembly for several thousand dollars. Of course I must do this in order to remain safe but this is clearly a safety issue that could have been catastrophic. Meanwhile I am out of a car for several weeks until the part arrives and out of at least $2000 as quoted by my mechanic ($1640 for the part). The car only has 146,500 miles on it so otherwise would have plenty of life left in it. I'm filing this complaint to add my voice to the open petition and toward the NHTSA's investigation in strong support of holding Toyota responsible for PREVENTING injury and death through a proper recall, as well as against burdening the car owner with the costs of making up for Toyota's negligence on this issue. At the least they need to cover the cost of these necessary safety repairs when they are warned by the lights and reinstate their warranty extension for this issue

I write to add my voice to the litany of complaints in support of NHTSA investigation DP23005. While on an interstate road trip recently the ABS, Traction Control, and Brake warning lights all came on. The brake felt squishy and didn't seem to be functioning as confidently as before. I altered my driving (giving plenty of distance, lowering my speed) so that in the event the brakes quit working I would have an exit strategy. I took it to my Independent Service Center as soon as possible who found the code C1391 and diagnosed the need to replace the master cylinder / booster assembly for several thousand dollars. Of course I must do this in order to remain safe but this is clearly a safety issue that could have been catastrophic.

The Toyota Prius of this generation has a known defect in the brake booster pump assembly. About 2 weeks ago the dash lights came on for ABS, Traction control, general warning light. The brakes work but feel soft, and a motor sound pulses behind the steering column every 8-10 seconds. My mechanic pointed out it is a known problem where the ABS booster pump has a faulty valve that doesn’t allow proper pressure to build to engage ABS system. I cannot afford the Repair: $3890 for master cylinder and brake booster. My concern is that most people can’t afford this repair and without a functioning ABS system, people are put at risk from this generation of Prius. Toyota did offer a customer service program acknowledging the issue, but that program only helped if these issues occurred before 2022. With the known issue, why wasn’t a recall required? Toyota should be required to address this safety issue. How many of these Prius are on the road where customers are expected to perform a $4,000. Repair to keep up the safety standards. The car is available for inspection upon request. Thank you.

I was driving and all of a sudden the emergency brake light, the ABS brake light and a couple more turned on and I had no more brakes. I had just driven 25 miles with it and stopped at many red lights along the way with no issue and NO WARNING lights. I could have gotten into a major accident if it had happened anywhere else in my route. Fortunately, I was about a mile from my house and the hybrid motor helped slow the car down. I was unable to stop at any stop sign in my development and here again was very fortunate that there were no cars along the way. Once I got home, I got it towed to Toyota and was told it is an internal failure of the actuator. I contacted Toyota America and was just told that there was a campaign to repair this but that I had passed the date. My car has only been serviced at the same Toyota in my city since I got it. I religiously brought it every 5000 miles. I am shocked that they never mentioned this campaign to me and that they didn't initiate a repair during the campaign. This is a major issue that needs to be addressed and Toyota needs to be held accountable.
