Lexus intelligent Power Module (IPM) inside the inverter module may contain transistors that have higher operating temperatures than the solder can support and the transistors may be heat damaged by the solder.
The short version
Toyota Motor Engineering & Manufacturing reported a problem with the hybrid propulsion system inverter. Here is what owners need to know.
The Intelligent Power Module (IPM) inside the inverter module may contain transistors that have higher operating temperatures than the solder can support and the transistors may be heat damaged by the solder. If this occurs, various warning lamps, including the malfunction indicator lamp, slip indicator light, brake system warning light, and master warning light, will be illuminated on the instrument panel.
The vehicle may enter a fail-safe/limp-home mode that limits the drivability of the vehicle. It is possible that the hybrid system will shut down while the vehicle is being driven, causing the vehicle to stall unexpectedly, increasing the risk of a crash.
Toyota will notify owners, and dealers will replace the IPM free of charge.
