The U.S. National Highway Traffic Safety Administration (NHTSA) is inspecting an apparently defective steering apparatus of Hyundai Motor’s 2011 Santa Fe models.

The agency says a driver could lose control of the car if a loose bolt separates the steering shaft from the system.

Around 70-thousand 2011 Santa Fes will be subject to the agency’s investigation.

The administration says it received a complaint by a driver who completely lost control of his Sanfe Fe, and Hyundai Motor also received a similar complaint. No accidents have been reported due to the defect.
