2014 Toyota Prius recalls
Inverter
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. An unexpected hybrid power system shut down may increase the risk of a crash.
Fix: Toyota will notify owners, and dealers will perform a software update for the hybrid system. If the vehicle has experienced an inverter failure with certain hybrid system faults related to this condition, the inverter assembly will be repaired or replaced, prior to software update.
Recall 20V369000 · Jun 2020Hybrid System
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. If the hybrid system shuts down unexpectedly, it can increase the risk of a crash.
Fix: 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. 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.
Recall 18V684000 · Oct 2018Software, Inverter
Can stallIn 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. 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.
Fix: 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.
