GM is recalling more than 220,000 full-size sedans because the electric parking brake may stay partially engaged while driving.
The 2014-2015 Chevrolet Impala and 2013-2015 Cadillac XTS have faulty electric parking-brake software that can result in the pads touching the rotors even after the brake is released. Of course, driving with the pads dragging the rear rotors causes excessive brake wear and can lead to rotor warpage and a smoky, jerky driving experience. The parking-brake dash light may not illuminate when this is happening, GM said. A total of 205,000 cars in the U.S. will now need updated software, an increase from the 133,000-car figure GM had initially filed with the National Highway Traffic Safety Administration on September 4. GM said it first discovered the problem after NHTSA opened an unrelated investigation in April on the 2014 Impala’s auto-braking feature, in which an owner alleged that it activated by mistake, triggering a rear-end collision. That investigation, which is still ongoing, led to GM buying back a car with a dragging parking brake in May and conclude, through unspecified warranty claims, that a recall was necessary.

The 2014 Impala was recalled twice over the summer for power steering that could cut out and loose joint fasteners (a problem it shared with the XTS, the only other time the Caddy has been recalled this year). The 2014 Impala Limited, the previous-gen car sold only to rental fleets, was also recalled for replacement of the ignition key in June. By GM’s tally the automaker will have initiated 68 recalls this year totaling nearly 26 million cars in the U.S. and that’s not counting the upcoming Corvette recall involving driver’s side airbags and parking brake operation.
