General Motors on Sunday recalled more that 221,558 vehicles from its Cadillac XTS and Chevrolet Impala lines to address an identified brake pad flaw that raises the chances of sparking a fire. No injuries or deaths were directly linked so the move is a preventive measure, but it follows a trend that has landed GM in trouble with the U.S. government.

The affected cars include 2013 through 2015 model year XTS and 2014 and 2015 year Impalas. However, the latest round raises the total GM recall tally this year to 15 million worldwide, The Guardian reported. Most of the recalled XTS and Impalas were sold in the U.S. – 205,309 – with the rest leaving GM dealerships in Canada and other territories.

In an official statement, GM stated that it has come to its attention that in the XTS and Impala “there is potential for the rear brakes to generate significant heat, smoke and sparks… Brake pads that remain partially engaged with the rotors may cause excessive brake heat that may result in a fire.”

Addressing the brake problem as a “condition” in the statement, GM said it was “not aware of any crashes, injuries or fatalities.”

Reuters reported that a National Highway Traffic Safety Administration letter indicated that brakes were also discovered not fully retracting after use.

The federal agency’s deputy administrator David Friedman has landed in hot water for what some perceive as lack of sufficient enforcement of GM after it acknowledged faulty ignition switches were linked to at least 19 deaths.

During a recent U.S. Senate hearing, Friedman shifted to blame to General Motors, telling a panel that included U.S. Sen. Claire McCaskill (D-Mo.): “NHTSA was actively trying to find the ball … General Motors was actively trying to hide the ball.”
