Hello, The hybrid system on the involved vehicles contain an Electric Vehicle (EV) fuse which may malfunction if the vehicle is repeatedly operated in EV mode under high-load driving conditions, such as during a long hill climb. If the fuse malfunctions, warning lights and warning messages will illuminate. In some cases, the vehicle can be driven, but with reduced power. In other cases, the hybrid system could shut down resulting in the loss of motive power. Power steering and braking will not be affected. Loss of motive power while driving at higher speeds can increase the risk of a crash. Remedy Toyota is currently preparing the remedy. The remedy, when available, will involve the replacement of the EV fuse with an improved one at NO CHARGE. check you own car : Lookup Safety Recalls & Service Campaigns by VIN
