2006 Lexus RX 400h

Toyota has issued a voluntary recall on certain models of its Lexus RX 400h luxury hybrid crossover as well as the car’s corporate cousin, the Toyota Highlander Hybrid. The recall affects only the 2006 and 2007 model years so we’re talking about the previous generation cars here.

According to Toyota, the Intelligent Power Module (IPM) located inside the vehicles’ Hybrid System Inverter can malfunction. 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, which will most likely cause the vehicle to enter a fail-safe driving mode. In some cases, a safety fuse may blow, causing the vehicle to coast to a stop.

In total, the latest recall affects some 36,700 Lexus RX 400h models and 45,500 Highlander Hybrids here in the U.S.

Owners of the affected vehicles will be notified next month and will be directed to take their vehicles to their nearest Toyota dealer, which will inspect the components in concern and make any replacements if necessary.
