Toyota will recall 109,000 2012 through 2014 model-year Prius V hybrids to address a software issue that could cause the vehicles to slow or stall suddenly.
The software glitch is associated with two components: the motor/generator control electronic control unit, and the hybrid control electronic control unit.
A fault can cause hardware in both of those units to overheat, triggering a fail-safe mode that limits functionality.

In some cases, the hybrid system may shut down entirely, resulting in a complete loss of power that brings the car to a stop, Toyota says.
The fault in the control units will also trigger dashboard warning lights.
This appears that it could be similar to a software issue that led to the recall of 700,000 2010-2014 Prius Liftback models in February 2014.

The Prius V is the largest of the three remaining models in the Prius "family," which also includes the original Prius Liftback and Prius C subcompact.
Toyota ended sales of the Prius Plug-In Hybrid in June, though that model will return sometime after an all-new fourth-generation Toyota Prius is unveiled this fall as a 2016 model.
