General Motors issues sixth recall of the year, a record

General Motors is recalling 221,000 Cadillac XTS and Chevrolet Impala cars after a problem with the electronic parking brake arm was discovered.
The recall includes 205,000 vehicles within the United States.
The car manufacturer said the parking brake's piston actuation arm may not fully retract when released and may partially engage with the rotor. This could cause excessive heat and poor performance.
Vehicles "may experience poor vehicle acceleration, undesired deceleration, excessive brake heat, and premature wear to some brake components. If the brake drag is significant or if the vehicle is operated for an extended period of time in this condition, there is a potential for the rear brakes to generate significant heat, smoke, and sparks," GM said in a release.
The recall covers 2013-15 XTSs and 2014-15 Impalas.
The problem was discovered after an investigation launched by the National Highway Traffic Safety Administration in April.
GM said it's not aware of any crashes, injuries or deaths related to the parking brake problem.
The recall is GM's 67th of 2014, a record for the company. It has called back some 26 million vehicles in the United States this year.
