Ford is recalling nearly 423,000 cars and SUVs in North America because the power-assisted steering can fail while they're being driven.
The recall covers certain Ford Flex and Taurus vehicles, as well as the Lincoln MKS and MKT from 2011 through 2013. Also covered are the Ford Fusion and Lincoln MKZ from 2011 through 2012 and some 2011 Mercury Milans.
Ford says an intermittent electrical connection can cause the power steering to stop. That sends the steering into manual mode, making the vehicles harder to control.
Dealers will either update power steering software or replace the steering gear.
The company also is recalling 19,500 2015 Mustangs with 2.3-Liter engines due to high underbody temperatures that could degrade the fuel tank. Dealers will replace a heat shield and add insulation.
