"Corrosion of the electric power steering module and the torque sensor connector may cause a loss of electric power steering assist," said NHTSA in its recall summary. "A greater steering effort would be needed to control the vehicle if power steering is lost, increasing the risk of a crash."
A stop-delivery order on the cars was issued to Chevrolet dealers on March 16.
There are no accidents or injuries linked to the recall, GM spokesman Tom Wilkinson told Edmunds.
GM said in a statement that manual steering functionality is retained, but would require an increased steering effort, particularly at lower speeds.
GM received a complaint about the power steering loss in the cars in September 2015 from the LaGrange, Illinois police department, according to a document filed with federal safety regulators.
Chevrolet dealers will replace the steering-gear assembly. A date has not been set for the recall. Owners can contact Chevrolet customer service at 1-800-222-1020.
Edmunds says: Recall notices are expected to go out within 60 days, according to federal regulations.
