Owner reports
Selected complaints filed with NHTSA by 2013 Toyota Prius c owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2013 Toyota Prius C. The contact stated that while driving at slow speeds, the vehicle stalled as a system failure warning message appeared on the instrument panel. The vehicle inadvertently turned. The vehicle was restarted but shifted into limp mode with the message displayed. The contact was able to restart the vehicle and then drove the vehicle to the residence. Upon investigation, the contact discovered NHTSA Campaign Number: 20V369000 (Hybrid Propulsion System) and 14V053000 (Hybrid Propulsion System, Electrical System) which she linked to the failure. Neither the dealer nor the manufacturer was notified of the failure. The vehicle was not repaired. The failure mileage was approximately 66,000.
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.
The contact owns a 2013 Toyota Prius C. The contact stated while driving approximately 40 MPH, the vehicle shut-off without warning. The contact pulled over and was unable to restart the vehicle.

The manufacturer was informed of the failure and the contact was informed that the VIN was not under recall. The failure mileage was approximately 80,000.
While in line at a church food bank, with cars in front and in back of me, the Prius C suddenly lunged forward. While my foot was on the brake, I hit the car in front of me. The impact was strong enough to cause almost $1400 worth of damage to the car in front of me and more than that for my car. My car's fender is damaged as well as the lights and hood of the car. My sister was in the passenger seat and nephew in the back seat. My sister told me that all she could see when the sudden movement started was my foot on the brake. She said that from where she was sitting, she could not see if my foot was on the gas pedal but could clearly see when my foot was on the brake. So lucky that there were no injuries either to the husband and wife in the car in front of me nor to my passengers. …
According to Toyota Dealership, "WILL NEED TO REPLACE (MG1) HV TRANSAXLE UNIT AS 1ST STEP IN ORDER TO TO BE ABLE TO PROCEED WITH DIAGNOSE AND CHECKED FOR ANY OTHER SHORTED COMPONENTS". Vehicle is available for inspection. Vehicle was being driven on a city street towards a red light when the vehicle experienced a jolt and lost complete acceleration power and a "Check Hybrid System" was displayed on the dashboard. Luckily all vehicles behind were already coming to a stop for the red light, otherwise, the safety of my family and myself may have been put in more serious harm. Vehicle able to crawl to a nearby gas station. Attempted to use remaining battery power to drive back to residence nearby, but lost all battery power/function and puled into a bus lane where vehicle was towed from. There were no warning lights or messages displayed prior to the incident. …
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. …
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. …
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 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.
