Toyota Motor Sales, U.S.A. Inc., announced that it is advising the National Highway Traffic Safety Administration (NHTSA) of plans to conduct voluntary safety recalls on 700,000 of its vehicles due to electronic issues in the U.S.
The recall effects Model Year 2010-2014 Prius vehicles and, combined, approximately 260,000 Model Year 2012 Toyota RAV4, 2012-2013 Toyota Tacoma, and 2012-2013 Lexus RX 350 vehicles sold in the United States to address two separate issues. Toyota will update the motor/generator control ECU and hybrid control ECU software on certain Model Year 2010-2014 Prius vehicles
The software’s current settings 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.
Toyota will update the skid control ECU software on certain 2012 Toyota RAV4, 2012-2013 Toyota Tacoma, and 2012-2013 Lexus RX 350 models in order to address an electronic circuit condition that can cause the Vehicle Stability Control, Anti-lock Brake, and Traction Control functions to intermittently turn off. If these systems are off, standard braking operation remains fully functional.
Toyota has received no reports of accidents or injuries associated with either condition.
