Lexus RX 400h – Click above for high-res image

There's a problem with some 2006 and 2007 model year Toyota Highlander Hybrid and Lexus RX 400h vehicles. Today, Toyota announced that it will voluntarily recall 45,500 Highlander Hybrid and 36,700 Lexus RX 400h vehicles that were sold in the States. What's the problem? Toyota says there is a control board with transistors inside the Intelligent Power Module (IPM) in the Hybrid System Inverter and that, "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." Whoops.

Toyota says that the worst-case scenario is that the vehicles will either go into a fail-safe mode or the fuse will blow and the vehicle will coast to a stop. In order to fix the problem, Toyota needs to get the required replacement parts and will notify owners by mid-July when and how they can get the vehicles repaired for free. If you're curious about your own vehicle, you can call Toyota or Lexus directly. Phone numbers and more details are available in the press release after the jump. Information about other Toyota company recalls can be found in the archives.

Toyota Announces Voluntary Safety Recall of Certain 2006 and 2007 Model Year Highlander Hybrid and RX 400h Vehicles
TORRANCE, Calif., June 29, 2011 – Toyota Motor Sales, USA, Inc. (TMS), today 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.

Detailed information and answers to questions are available to customers at www.toyota.com/recall and the Toyota Customer Experience Center (1 800-331-4331) or www.lexus.com/recall and Lexus Customer Satisfaction (1 800-255-3987).

      So Toyotas either run rapidly out of control or do not run at all. At least they have no grey area

      Another week, another Toyota/Lexus recall. Who will they blame it on this time, the Americans or the Chinese?

      Automakers are much quicker to issue recalls now and that is good for the consumer. I am not a Toyota fan but good that they are not sweeping everything under the carpet anymore. People should see this as a win for the consumer regardless of what your favorite car lines are.

        You can't be for real! If you and the other thugs are being paid just to make Japanese automakers look bad and make American automakers look good, you should both be fired!

        That's just how you see it. Toyota's been killing jobs and people for years with their unsafe cars. Now they're only getting in front of problems only after they've murdered hundreds if not thousands of people. These recalls are simply a way for them to pretty their image for us. It's just the Japanese way.

      What a moronic concept: sell a heavy ponderous car/truck, then add a mess of hybrid batteries, electronics, and motors so that the lessors can pat themselves on the back about their green consciousness. Have we (USA) become a nation of stupid people?
