Toyota is recalling 45,500 Toyota Highlander Hybrid and 36,700 Lexus RX 400h crossovers from the 2006 and 2007 model years due to a defective power module. Some of the transistors on the module were “inadequately soldered” during manufacture and could become damaged.
If the parts do fail, the car will alert drivers with warning lights on the gauge display and then enter either a fail-safe or “limp home” mode. In a worst case scenario, the entire hybrid system will fail and the car will be essentially dead.
The recall will begin in mid-July when Toyota is able to obtain enough replacement parts to address the full recall. For more info, owners can call Toyota at 800-331-4331, Lexus at 800-255-3987 or the National Highway Traffic Safety Administration at 888-327-4236.
