General Motors is recalling 674 Cadillac CTS cars from the 2012 model year for a problem with the brakes. The affected CTS cars “may have a condition in which the power vacuum brake boost pushrod retention nut may not be torqued to the proper specification,” the National Highway Traffic Safety Administration reports.

If the nut is not properly torqued, it could loosen and the pushrod can separate from the brake pedal. If this happens, the driver can lose the car’s braking ability, which could cause a crash. Affected 2012 Cadillac CTS vehicles were built from Oct. 21, 2011 through Oct. 26, 2011. If you own one of the affected CTS cars, Cadillac will contact you to bring your car into the dealership, where it will be inspected and fixed free of charge.

Cadillac owners who have questions can call Cadillac at 1-800-458-8006 or NHTSA at 1-888-327-4236. Owners can also visit and search GM’s safety recall number 11318.
