This is a new recall for the ATS and supersedes a February 24, 2015, recall for 58,698 2013-'15 Cadillac ATS vehicles for the same problem. The new recall now adds the 2016 model as well.
"An ineffective replacement part was used" in the original recall, wrote GM spokesman Alan Adler in response to a query. "About 70 percent of the originally recalled vehicles had been fixed and will be fixed again."
The new recall is part of a global recall of 82,620 Cadillac ATS sedans.
"The power-operated roof panel systems on these vehicles will auto-close when the non-recessed portion of the ?slide' or ?tilt' switches are pressed and the roof panel is open," GM said in a statement. "Because these switches are not fully recessed, they can be actuated with less force than required to comply with applicable federal standards."
GM said it knows of no crashes, injuries or fatalities linked to the new recall and has received no customer complaints.
No information about the recall has been posted on the Web site of the National Highway Traffic Safety Administration, which oversees vehicle safety in the United States.
Edmunds says: Owners of these cars should stay in touch with their dealer regarding when it's time to make a service appointment. Vehicles that have been fixed as part of the previous recall will require another repair.
