“We were driving on a city street about 25-30mph and the car jerked suddenly and the lights on the dashboard illuminated and the Check Hybrid System message came up as well. The car was able to coast to a nearby parking lot. We attempted to drive the car home and the car stalled in the middle of the street. We were able to push the car off the road and then get it towed. The presented a potentially very dangerous situation as the car had a complete failure while driving in the middle of the road. The Toyota service department ran a diagnosis which returned DTC P0A94. …”

“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 NHTSA investigate this issue, as it appears to involve the same hardware defect acknowledged in other Prius models.”
