2008 Toyota Highlander Hybrid

When it rains, it pours. Toyota has announced a pair of separate but voluntary North America recalls covering approximately 235,000 vehicles built between 2006 and 2011. The larger of the two recalls targets Toyota's hybridized crossovers, the Lexus RX400h and Toyota Highlander Hybrid. 133,000 units, including 2006-2010 Highlander and 2006-2008 RX crossovers are covered in the campaign. The other recall affects 102,000 IS350 sedans, IS350C convertibles and GS350 sedans built between 2006 and 2011.

With the CUVs, the faults in the parallel circuits of the transistors can cause heat damage in the inverter assembly, triggering an abundance of warning lamps and sending the vehicle into limp mode. The Lexus sedans are being recalled due to loose bolts on the variable valve timing controller. Detected by unusual underhood sounds on startup, the issue can cause the engine to stop while driving. The inverter issue is also triggering similar recalls in Japan and Europe.

At the moment, it's unclear if any of these issues have caused any crashes or injuries. Toyota says it plans to notify owners of the recall via snail mail. Additional information for owners can be found on the recall sites for Toyota and Lexus or by calling Toyota's customer service line, at 1-800-331-4331.

Toyota Announces Voluntary Recalls

TORRANCE, Calif., Sept. 3, 2013 – Toyota Motor Sales, U.S.A., 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 an abnormal noise just after start-up.

Owners of vehicles subject to these recalls will receive a notification by first class mail.
