While I was driving on the freeway the dash lit up with multiple lights. Simultaneously, I lost power to the car and could not accelerate and only break. The steering was tight and I could not steer correctly. Then a message that said, CHECK HYBRID SYSTEM STOP THE VEHICLE IN A SAFE PLACE IMMEDIATELY. The was slowing down and I had to pull over on the side of the freeway. There were no fluids leaking from the car.The car did not power back on nor run for over 10 minutes. The incident put my safety and other safety at risk by turning off while driving highway speeds. I was afraid for my life. There is an open recall which has not yet been resolved Major Safety Recalls for the 2013 Prius •The Hybrid Inverter Module (Critical Recall): Excessive voltage inside the Intelligent Power Module (IPM) can cause the hybrid system to overheat, shut down completely, or put the car into "limp home" mode while you are driving.

My 2013 Toyota Prius has a failed inverter/converter assembly, including the Intelligent Power Module (IPM). This component is critical for vehicle operation and designed to last the life of the car. Premature IPM shorting and inverter failure is a known defect acknowledged by Toyota through multiple recalls and service campaigns for other VINs with the same part number. My vehicle is giving codes P0A94 and P0A1A which are also listed in the recalls for other Prius models of similar age. My vehicle experiences the same failure, yet Toyota has denied goodwill coverage, claiming “insufficient service history.” Routine maintenance like oil changes and brake inspections does not affect this component, making the denial unreasonable. There is nothing to service on the inverter. This defect poses a serious safety risk, sudden inverter failure caused total loss of power while driving and loss of power steering, it was difficult to pull my car off the road. This poses a danger to drivers, passengers, and others on the road. Toyota’s exclusion of my VIN from coverage leaves me financially responsible for a known safety defect. I request the federal safety agency to investigate Toyota’s handling of inverter/IPM failures, the denial of goodwill assistance for affected VINs, and ensure that Toyota addresses this life-threatening defect consistently across all affected vehicles instead of narrowing the scope on who gets coverage when this is a dangerous electrical malfunction.

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 the federal safety agency investigate this issue, as it appears to involve the same hardware defect acknowledged in other Prius models.

My vehicle has under 150,000 miles. I was driving on the highway and my Prius lost power and left me on the side of the road. I took it to Toyota to run a diagnostic in Elk Grove Ca. I was told the ipm inverter, control computer had to be replaced and it would cost me $5,200.00. This is a real disappointment because I don’t have this money to fix the vehicle.

I was driving on the expressway and experienced a sudden loss of power. The internal combustion engine suddenly stopped and did not deliver any power to the wheels. I immediately received a message on the system that said 'Check Hybrid System Stop Vehicle in a Safe Place'. The electric motor still continued to provide some power with the available battery charge. I was able to make it to the shoulder of the road but it was challenging to get to the shoulder with no power or warning and high speed traffic. My wife and I were in the vehicle. The vehicle had no engine or error codes until the failure on the expressway. The vehicle has the code P0A1A and P0A94. This is consistent with the error codes in the federal safety agency 19V491000 recall and Toyota Safety Recalls E0E and F0R.

While driving, I received a warning "hybrid system malfunction". Within seconds, the vehicle powered off and the steering wheel LOCKED. I had no control of the car and came to an abrupt stop in lane 1 of a two lane road. I was fortunate that it was late in the evening with few cars on the road, had I been on the highway during rush hour the outcome, due to loss of power and control (steering), could have been catastrophic and perhaps fatal for me or other commuters. I note that in 2014, Toyota notified the federal safety agency of a recall to, "rectify software in two of the Prius's electronic control units, one for the motor/generator and the other controlling the hybrid system." Further Toyota said, "In rare circumstances, it could shut down the hybrid system itself, resulting in loss of power and the vehicle coming to a stop". This is exactly what happened to me the other night. Toyota claims, in 2014, that "it has received no reports of accidents or injuries related to the problem." This seems to be an extraordinarily amount of good luck as I could have been easily rear-ended the other night. Curiously, in this the federal safety agency data base, another owner reported an incident (11439720) on November 8, 2021, that is similar to the experience I had just days prior. And our VINS are eerily close. Coincidence? Not likely. Does the 2014 recall apply to my car and if not, why not given I experienced the exact same symptoms?

Toyota is trying to cover up the true number of vehicles subject to the hybrid system recall.. Toyota claims this vehicle is not the subject of recall, yet the vehicle displays all the symptoms described in the recall.. 1.) the vehicle was in motion at freeway speed on westbound hwy 92 on 12/27/2020 at approximately 6:30pm 2.) the vehicle lost all power.. Dashboard lights came on.. Error message said "hybrid system failure" 3.) power to braking and steering remained 4.) vehicle went off the freeway, with no power, down an exit ramp, and came to a stop, luckily, in a legal parking place, at the curb on de anza blvd.. This is what toyota said publicly: 'the involved vehicles were designed to enter a failsafe driving mode in response to certain hybrid system faults', the automaker explained. 'toyota has found that in rare situations, the vehicle may not enter a failsafe driving mode as intended. If this occurs, the vehicle could lose power and stall. While power steering and braking would remain operational, a vehicle stall while driving at higher speeds could increase the risk of a crash.'

My 2012 prius c with 90,000 miles began to lose power/speed driving when check hybrid system warning suddenly came on tonight. It was unresponsive to the gas peddle, even at full throttle. Did not allow enough time to pull to the side of a busy road before it lost all ability to drive, leaving me stalled near intersection. A stranger helped push my car off the main road until aaa sent a tow truck. Had this occurred one mile later, I would've stalled on the 25 southbound freeway going from lone tree to denver at a very busy time in the evening without warning (scary thought). Upon arriving home with the towed vehicle, I attempted to start the engine again, but it would not start. Turned off the ignition, removed keys, but a low sound I've never continued for several minutes. After that, the car was completely dead. Dashboard won't light up, no working horn, power locks, windows, alarm. I now have no functioning vehicle and have no idea what caused my car to lose power while driving.

My 2012 toyota prius c four model (purchased new in august, 2012) with approximately 5,200 original miles experienced a loss of power and total failure (engine stalled right after the hybrid motor warning light appeared) of the 2012 toyota prius c hybrid inverter engine due to an electrical panel defect while exiting I 495 in alexandria, virginia on the late evening of july 6, 2013. Toyota corporate (1‑800‑331‑4331) opened case file # 1307101143 and our local toyota dealership in alexandria, va. Was very helpful and proactive in replacing the entire hybrid inverter motor component on the 2012 prius c under factory warranty and at no charge to me as the original owner of the vehicle. Toyota corporate also advised me that they are unaware of any recalls or other reported problems with the 2012 toyota prius c hybrid inverter motor so our situation was, hopefully, an anomaly.
