General Motors is recalling nearly 800,000 trucks that have been found to suddenly lose power steering, potentially causing drivers to lose control of their vehicle. The problem, according to the National Highway Traffic Safety Administration, can be triggered when a vehicle is using a lot of electrical power, including during low speed turns. If the trucks’ power levels drop below a certain point, power steering can be suddenly disabled. The sudden steering jolt can cause drivers to lose control. The recall impacts certain 2014 Chevrolet Silverado and GMC Sierra pickup trucks.
