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.

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.

Immobilized failure due to combination of brake hose failure preventing hybrid control/shift actuator. Hybrid steering lock became disengaged and could not communicate with the certification ecu due constant power being disabled due to complete main body failure. Hybrid system cannot go back into park however ecm side did. Ecm was not receiving power as dealer coded main body as a plug in hybrid effectively disabling fuel systems (including emissions/fuel safety) causing full misclassification in the smart key certification process. Car starts, goes into ready and disables LIN comms alongside cutting main relay due to tailgate and fuel constant powers being cut while driving.

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.

Without warning my 2013 prius C stalled on the freeway with a hybrid battery warning. When the car was shut off it had intermittent problems with starting. After jumping the car battery , it ran normally again for some time before the stalling problem persisted. The hybrid battery stopped running and I received a warning light. Diagnostics at my repair shop said it was an inverter issue.I see that toyota has recalled several models for similar issues with the inverter. When the car is jumped it seems to work for a short time before stalling out again. Has created a real safety issue for me and there is a real lack of information on behalf of toyota on whether or not it will be covered under existing models. It seems like every model toyota from this year was recalled for an inverter issue. The car does run normally on occasion, charges the battery, and will run on EV, but mostly remains in a stalled out low power mode after it has these stalling episodes.e Diagnostics have stated to me that the car batteries are healthy and I relplaced the 12V and several fuses etc throughout this process with similar results.
