Toyota Prius: Powertrain
Affects Toyota Prius · 2012–2015 — about 363 vehicles.
The hazard
On certain plug-in hybrid vehicles, the electric vehicle (EV) hybrid battery's fuse could be subjected to excessive thermal stress and potentially fracture if the vehicle is operated by the electric motor under high-load driving conditions, such as during a long ascent. This would illuminate warning lights and warning messages in the instrument cluster, and in some cases cause the vehicle to enter a fail-safe mode resulting in reduced motive power. In other cases, the hybrid system could shut down, resulting in loss of motive power, which could increase the risk of a crash causing injury and/or property damage. Correction: Dealers will replace the EV fuse with a new one of an improved design.
