Toyota has recently announced a recall for several units of the Prius because of some problems with the motor / generator control ECU and the hybrid control ECU.
According to the car manufacturer, the affected vehicles could have higher thermal stress in certain transistors and this may lead to some damages. If this happens, the vehicle can enter a failsafe mode and various warning lights will illuminate. The loss of power and the cars coming to a stop might also happen, but in rare circumstances.
“In the involved vehicles, the current software settings for the motor/generator control ECU and hybrid control ECU could result in higher thermal stress in certain transistors, potentially causing them to become damaged. If this happens, various warning lights will illuminate and the vehicle can enter a failsafe mode. In rare circumstances, the hybrid system might shut down while the vehicle is being driven, resulting in the loss of power and the vehicle coming to a stop”, says the automaker in its press release.
The affected Toyota Prius v hybrid vehicles are from the 2012 to 2014 model years and their owners will be contacted by the automaker which will be using first class mail. An exact notification schedule for the recall hasn’t been announced at this point. The necessary repairs / replacements will be made free of charge to the owners.
