High Voltage
Issue: On certain vehicles, a bolt in the inverter assembly for the hybrid system may not have been tightened properly. As a result, the vehicle could enter a reduced power mode or lose power to the wheels. Additionally, if the bolt becomes loose in the inverter assembly and the ignition is on, it could cause a short circuit. Safety Risk: A loss of power to the wheels could increase the risk of a crash. A short circuit can create the risk of a fire. Corrective Actions: Toyota will notify owners by mail and advise you to take your vehicle to a dealership to inspect the hybrid inverter assembly bolt. The dealer will tighten the bolt or, if necessary, replace the inverter assembly.
