    Electrical system

    Toyota is recalling certain model year 2006-2007 highlander hybrid and lexus rx400h passenger cars manufactured from february 16, 2005, through august 30, 2006. A module inside the inverter module may contain inadequately soldered transistors that during high-load driving, may be damaged by heat caused by the large current. 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.

    Risk: 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.

    Remedy: Toyota/lexus mailed an interim owner notification on july 19, 2011 to advise owners of this recall and the fact that they will receive a future notice when parts become available to complete repairs. Toyota dealers will inspect the hybrid inverter production number to determine whether the inverter contains suspect transistors and replace the module free of charge. Owners may contact toyota at 1-800-331-4331.
