The bracket between the brake pedal assembly and the rod that actuates the brakes may have been fractured during manufacturing or may be susceptible to fracture when the brake pedal is depressed.
"If the bracket fractures, the driver would not be able to apply the brakes, increasing the risk of a crash," NHTSA said in its recall summary.
GM is unaware of any crashes, injuries or fatalities linked to the recall, GM spokesman Alan Adler told Edmunds on Saturday.
This is part of a larger global GM recall of 2,679 vehicles, including Canada, Mexico and exports.
Cadillac dealers will inspect the bracket and, if necessary, replace the brake pedal, including the affected bracket. The recall is expected to begin on August 1. Owners can contact Cadillac customer service at 1-800-458-8006.
Edmunds says: This recall does not begin for several weeks. If you have an immediate concern, it's best to contact your dealer.
