2011 Toyota Prius

Toyota has announced a set of voluntary recalls covering 960,000 Prius, RAV4, Tacoma and Lexus RX350 models in the United States to address two separate issues. Worldwide, Toyota will have to recall a total of 1.9 million Prius cars.

The Prius recall affects about 700,000 2010-2014 models in the US, due to a fault in the motor/generator control ECU and hybrid control ECU software. It says that the current software could result in high temperatures on certain transistors and possibly damage them. When it fails, the error forces the car into failsafe mode. Toyota says that in rare circumstances, it could even shut the hybrid system down while the car is being driven.

Toyota spokeswoman Shino Yamada told Automotive News that the software update should take about 40 minutes, and dealers would start to be notified about affected vehicles today. She also told them that the first reported glitch occurred in May 2011 in the US when the system overheated and the car entered failsafe mode. The affected cars were built between March 2009 and Feb. 5, 2014, according to Automotive News. Toyota says that it has received no reports of accidents or injuries caused by either fault.

This is the third major recall for the third-generation Prius. In February 2010, Toyota recalled the model to fix an anti-lock brake software glitch, and in June 2013, cars were recalled in the US to fix the brake pressure accumulator.

The second recall affects 260,000 2012 RAV4, 2012-2013 Tacoma and 2012-2013 Lexus RX 350 models due to an electronic flaw that could cause the Vehicle Stability Control, Anti-lock Brake, and Traction Control functions to intermittently shut off. Scroll down for Toyota's full announcement.

Toyota Announces Voluntary Recall of Certain Toyota Prius, RAV4, Tacoma and Lexus RX 350 Vehicles

February 12, 2014
TORRANCE, Calif., February 12, 2014 – Toyota Motor Sales, U.S.A., Inc., today announced that it is advising the National Highway Traffic Safety Administration (NHTSA) of plans to conduct voluntary safety recalls of approximately 700,000 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.

As part of these recalls, owners of affected vehicles will receive a software update free of charge. Owners will be notified by first class mail when the software updates are available at their dealers.
