Fuel System recalls for the 2012 Toyota Prius

NHTSA 18V684000Oct 4, 2018Fuel System807,329 vehicles
Hybrid propulsion system
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2010-2014 Toyota Prius and 2012-2014 Toyota Prius V vehicles. Excessive voltage in the Intelligent Power Module (IPM) within the inverter may cause the hybrid system to shut down, causing the vehicle to stall while being driven.
Risk: If the hybrid system shuts down unexpectedly, it can increase the risk of a crash.
Remedy: Toyota will notify owners, and dealers will update the software for the motor/generator control electronic control unit (ECU) and the hybrid control ECU as necessary, free of charge. The recall began January 22, 2019. Owners may contact Toyota customer service at 1-888-270-9371. Toyota's number for this recall is J0V. Note: The software updates in this recall are needed even if the vehicle had the software previously updated under recalls 14V-053 or 15V-449.
NHTSA 14V053000Feb 12, 2014Fuel System698,457 vehicles
Hybrid propulsion system: inverter
Toyota is recalling certain model year 2010 through 2014 Prius vehicles. In the affected vehicles, the Intelligent Power Module (IPM) inside the inverter module (a component of the hybrid system) contains transistors that may become damaged from high operating temperatures. If this occurs, various warning lamps will be illuminated on the instrument panel and the vehicle will have reduced power allowing it to only drive a short distance.
Risk: The vehicle may enter a fail-safe/limp-home mode that limits the drivability of the vehicle. The hybrid system could also shut down completely resulting in a vehicle stall, increasing the risk of a crash.
Remedy: Toyota will notify owners and dealers will update the software for both the motor/generator control electronic control unit (ECU) and the hybrid control ECU, free of charge. If an owner experiences a failure of the inverter before the vehicle receives updated software, the dealer will repair or replace the inverter assembly with a new one at no charge. The recall began on March 21, 2014. Owners may contact Toyota at 1-800-331-4331.
