The recalls affect mostly U.S. vehicles, though a smaller number in Japan are also affected.

In the States, 373,000 Toyota Avalons from model year 2000 to 2004 are being recalled to fix an improper casting of the steering lock bar, which can cause cracks to develop on the surface if unaddressed. These cracks can potentially lead to the lock bar breaking, which could lead to a crash if the steering wheel locks. Of the accidents possibly linked to the defect, no injuries have been reported.

A steering issue -- though a different one -- is also at the heart of the voluntary recall of about 39,000 Lexus LX 470s from model year 2003 to 2007. According to a press release from Toyota:
"Lexus has determined that the construction of the steering shaft on involved LX 470s is such that the snap ring on the shaft may disengage when the vehicle experiences an unusually severe impact to the front wheels, such as striking a deep pothole. If the snap ring becomes disengaged and the steering wheel is then repeatedly turned to the full locked position, the steering shaft may disengage over time."

Also according to the press release, the company is unaware of any accidents related to this defect.
