Toyota is recalling roughly 133,000 model year 2006-2010 Highlander hybrid vehicles, and 2006-2008 Lexus RX400h vehicles.
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 lights, 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.
The owners of all affected Highlander and Lexus RX400h vehicles will be notified by Toyota, and local dealers will replace the IPM free of charge.
For further information on this recall, contact Toyota toll-free at 800-331-4331.
Vehicles that had their IPM previously replaced under recall 11V-342 are not affected by this campaign.
