2006 & 2007 Toyota Highlander Hybrid & Lexus RX 400h: Recall Alert

June 30, 2011

Toyota has issued a voluntary recall covering certain 2006 and 2007 Toyota Highlander Hybrid and Lexus RX 400h models. This voluntary recall involves approximately 45,000 Toyota Highlander Hybrid and 36,700 Lexus RX 400h models sold in the United States. The automaker says that no other Toyota or Lexus models are involved.

The problem

Toyota said the following in a press release issued today: “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.”  

Here’s what might happen:

  • Various warning lamps will illuminate on the instrument panel. In most cases, advises Toyota, the vehicle will enter a fail-safe driving mode. This results in reduced power during which the vehicle can still be driven, albeit 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.

What Toyota is doing

Toyota is currently working to obtain the necessary replacement parts, although no firm date has been given yet for when those replacement parts will arrive. In the interim, owners of affected vehicles will be notified by first-class mail in mid-July.

Once Toyota receives sufficient quantities of the replacement parts, owners will receive a second notification from Toyota, again by first-class mail, advising them to make an appointment to bring their vehicle to an authorized Toyota dealer to have the IPM inspected and replaced, if necessary. There will be no charge to owners for the repairs.
