Approximately 578 vehicles in the U.S. are affected.
"Under certain conditions of under-torque detection, the automatic tightening system may not tighten the front strut assembly lower mounting nuts and bolts to the proper torque specification," Mazda said in a statement. "A separation of the front strut and steering knuckle can cause significant loss of steering control and increase the risk of a crash."
There are no reports of accidents or injuries, Mazda said.
No information about the recall has been posted on the website of the National Highway Traffic Safety Administration, which oversees vehicle safety in the U.S.
Edmunds says: Owners with an immediate concern should contact their Mazda dealer now for the inspection. Others can wait for their official recall notice and then schedule a service appointment.
