"The steering system contains an intermediate shaft, which connects the steering wheel to the steering gear box," Toyota said in a statement. "In the involved vehicles, the intermediate shaft could have received an inadequate weld.
"Under some circumstances, the weld could separate, resulting in the loss of steering control and increasing the risk of a crash."
Toyota is not aware of any crashes, injuries or fatalities linked to the recall.
No information about the recall has been posted on the Web site of the National Highway Traffic Safety Administration, which oversees vehicle safety in the U.S.
