Toyota has issued a voluntary safety recall for two of its hybrid vehicles just weeks after issuing similar recall of some of its Prius vehicles. Both 2006 and 2007 model year Toyota Highlander Hybrid and Lexus RH400h owners may begin to see letters in their mailboxes this week over a faulty transistors on control board within the hybrid system inverter.
Toyota says some of these transistors may have been soldered improperly, which, under high-current conditions, can become heat damaged, and possibly explode. The automaker claims that, in most cases, the vehicles will enter a fail safe mode, allowing drivers to continue on for a short distance, however, in other circumstances, the vehicle may coast to a stop.
Around 45,500 Highlander Hybrids, seen in the photo above, may be affected by the issue. As well, 36,700 Lexus RX 400hs, seen in the photo below, may be potential candidates for failure.
Currently, the manufacturer is in the process of acquiring sufficient quantities of replacement parts and, once ready, owners will be able to set up free inspections and potentially have the intelligent power module in their SUV replaced.
