Roush Performance Products, Inc. (Roush) is recalling certain model year 2015 Ford Mustang GT Roush Stage 3 vehicles manufactured April 1, 2015, to October 31, 2015, and equipped with Roush Extreme Duty Half Shafts. The affected vehicles have a brake caliper guide pin that may not have been sufficiently tightened during installation of the half shafts. As a result, the caliper guide pin may loosen while driving, reducing the vehicle's rear braking ability.
Roush will notify owners, and Roush-authorized Ford dealers will tighten the caliper guide pin to the proper specification, free of charge. The recall began in February 2016. Owners may contact Roush customer service at 1-800-597-6874.
