The campaign is one of several recent programs to fix problematic electric power steering (EPS) systems.

Hyundai is the latest automaker to issue a recall for a problematic electric power steering (EPS) system, used in the 2011 Sonata.

The subject Sonata's EPS circuit board is prone to damage, sometimes resulting in loss of power-steering assist. Illumination of the EPS warning light serves as a failure warning to drivers.

"With a loss of power steering assist, extra steering effort will be required, especially at lower speeds, increasing the risk of a crash," the recall documents warn.

The company has been investigating related warranty claims for more than a year, eventually tracing the problems to a supplier manufacturing change involving the circuit board's protective coating.

Similar EPS recalls, for various specific reasons, have been launched by FCA, General Motors, Ford, Toyota, Mazda and other automakers.
