Washington — General Motors Co. is issuing two new recalls covering more than 68,000 newer cars for roof panel and parking issues.

The Detroit automaker said it is recalling 66,998 2013-15 Cadillac ATS sedans worldwide because the power-operated roof panel systems on the cars will auto-close when the non-recessed portion of the “Slide” or “Tilt” switches are pressed and the roof panel is open.

Because these switches are not fully recessed, they can be closed with less force than required to comply with applicable federal standards. The issue was discovered in testing of a 2016 model in January, which uses the same switches as the 2013-15 models. GM knows of no crashes, injuries or fatalities related to this issue and has received no customer complaints. The recall includes more than 58,000 vehicles in the United States.

GM is also recalling 1,331 2014 Chevrolet Impalas to reprogram the electronic parking brake module with new software. The electronic parking brake software may cause the parking brake pads to stay partially in contact with the rotor after the parking brake is disengaged.

The vehicles in this recall were part of a recall last year of 132,921 vehicles but received incorrect software reprogramming that came after NHTSA had launched an investigation into the issue in Impalas and Cadillac XTS cars. GM knows of no crashes, injuries or customer complaints in the vehicles again being recalled.

GM learned through a dealer in the Middle East in January that the software upgrade for the Impalas on GM’s Web-based portal “were erroneously changed from the revised software to the original software version” and the vehicles serviced after Jan. 21 may have gotten the wrong update.
