Toyota is recalling approximately 807,000 model year 2010-2014 Toyota Prius and model year 2012-2014 Prius v vehicles in the U.S.
The recalled vehicles were designed to enter a failsafe driving mode in response to certain hybrid system faults. In rare situations, the vehicle may not enter that mode as intended, posing the possibility that the vehicle could lose power and stall.
While power steering and braking would remain operational, a vehicle stall while driving at higher speeds could increase the risk of a crash.
The recall is designed to provide a remedy to address a new condition in the vehicles involved in the previous recalls announced in February 2014 and July 2015.
The previous recalls did not anticipate this new condition remedied with this recall.
What to do
Toyota will notify the involved owners once the software update is available, and dealers will update the software for all involved vehicles at no charge.
Owners may contact Toyota at (800) 331-4331.
