Fresh off an impressive showing in the 2011 J.D. Power and Associates Initial Quality Study, Toyota today announced a voluntary safety recall for 2006-2007 Highlander Hybrid’s and Lexus RX 400h vehicles.
Toyota says that some of the 45,500 Highlanders and 36,700 RX 400hs may have defective soldering on the Intelligent Power Module.
Because of the weak solder joints, the IPM “could be damaged from heat caused by a large current flow during high-load driving.” If this were to happen, a damaged transistor within the IPM will blow a circuit supply fuse and the instrument panel would light up like a Christmas Tree. Toyota says effected vehicles will “coast to a stop.”
At the moment, Toyota does not have replacement parts, but when they become available, owners of potentially effected vehicles will be notified via first-class mail advising them to make an appointment with an authorized dealer, where the IPM will be inspected and if deemed necessary, replaced free of charge.
Toyota says no other vehicles are involved.
