DETROIT — General Motors is recalling 221,558 Cadillac XTS and Chevrolet Impala sedans because the brake pads can stay partially engaged even when they’re not needed, increasing the risk of a fire.

The recall involves Cadillacs from the 2013-2015 model years and Impalas from the 2014 and 2015 model years. There are 205,309 vehicles affected in the U.S.; the rest of the vehicles are in Canada and elsewhere.

GM says the electronic parking brake arm that applies pressure to the back of the brake pads may not fully retract after use. If the brake pads stay partially engaged with the rotor, excessive brake heat may result in a fire.
