Toyota/Lexus has announced a voluntary safety recall for 36,700 2006-2007 Lexus RX 400h and 45,500 Highlander Hybrids due to a potential issue with the (IPM) Intelligent Power Module 

The Intelligent Power Module (IPM) located inside the Hybrid System Inverter contains a control board with transistors. Certain transistors on the control boards in some of the subject vehicles were inadequately soldered and could be damaged from heat caused by a large current flow during high-load driving. If this were to occur, various warning lamps will illuminate on the instrument panel. In most cases the vehicle will enter a fail-safe driving mode, resulting in reduced power in which the vehicle can still be driven for short distances. In limited instances, the power supply circuit fuse could blow when the transistor is damaged. If the fuse blows, the hybrid system will stop and the vehicle will coast to a stop.

Owners will be first be contacted by mail in mid-July, with a follow-up letter to arrange a dealership appointment. Should you have any concern, I suggest contact Lexus www.lexus.com/recall or www.toyota.com/recall
