Toyota is recalling 412,000 cars, mostly the Avalon model, in the U.S., and another 16,420 vehicles in Japan for steering problems, the automaker said Thursday.

The 373,000 Avalons being recalled in the U.S. range from the 2000 model year through to 2004 and have improper casting of the steering lock bar — a component for the steering system — causing cracks to develop on the surface.

In some cases, the crack can cause the lock bar to break, potentially leading to a crash if the steering wheel locks, the world's No. 1 automaker by car sales said. No injuries have been reported from the accidents that may be caused by the defect, it said.
