Affected pickups include about 690,685 Chevy Silverado and GMC Sierra 1500s in the U.S., as well as 80,000 in Canada and 25,000 in other countries. The Silverados were manufactured between Jan. 30, 2013 and Sept. 4, 2014, and the Sierras between Jan. 29, 2013 and Sept. 4, 2014.
The problem has been linked to an issue with the power steering that can cause the trucks to lose electric power steering and then be over-compensated by the return of EPS assist, according to the National Highway Traffic Safety Administration (NHTSA).
“The loss and sudden return of EPS assist typically happens within a 1 second period and is caused by an electrical/software issue,” NHTSA said. “Events that demand high current, such as low speed turns, can cause temporary low voltage conditions.”
The first incident associated with the issue was reported back in February, and the recall was ordered on June 22.
GM has not yet issued a recall schedule for dealers or owners, but said it will make necessary work on the software and reimbursements.
