Here is the current recall. Below it is the previous one from 2011. The Lexus site says my 2006 VIN is not recalled. I had my board changed during the original 2011 recall.
TORRANCE, CA September 3, 2013 – Toyota Motor Sales, USA, Inc. today announced that it will conduct two voluntary safety recalls. One involves approximately 133,000 MY 2006-2010 Highlander Hybrid and MY 2006-2008 Lexus RX 400h vehicles. The other involves approximately 102,000 MY 2006-2011 Lexus IS 350, IS 350C, and GS 350 vehicles.
In the involved Toyota Highlander Hybrid and Lexus RX 400h vehicles, transistors within the hybrid system's inverter assembly can experience heat damage due to variations in characteristics of the transistors' parallel circuits. Should this occur, various warning lights on the instrument panel will illuminate, and in most cases the vehicle will enter "limp home mode." In limited instances, the hybrid system will shut down and resulting in the vehicle stopping while the vehicle is being driven.
In the involved Lexus IS 350, IS 350C and GS 350 vehicles, bolts used to secure the variable valve timing control device can become loose, causing the vehicle to stop while being driven. Early warning for this condition can be identified as a brief rattle noise for approximately 1 second upon a cold start-up.
Owners of vehicles subject to these recalls will receive a notification by first class mail.

On June 29, 2011, Toyota Motor Sales (TMS), U.S.A., Inc. announced that it will conduct a voluntary safety recall involving approximately 45,500 Highlander Hybrid and 36,700 Lexus RX 400h vehicles sold in the U.S. No other Toyota or Lexus vehicles are involved.
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.
Toyota is currently working on obtaining the necessary replacement parts. Once the replacement parts are available, we will notify owners. In the interim, owners of the involved vehicles will be notified of the recall by first-class mail in mid-July 2011.
Once the replacement parts have been produced in sufficient quantities, Toyota will send a second owner notification by first-class mail advising owners to make an appointment with an authorized Toyota dealer to have the IPM inspected and, if necessary, replaced at no charge.
