Imagine trying to apply the brakes on your new truck but the brake pedal is defective, loose or just isn't working at that moment it would be difficult to avoid a serious accident. General Motors is recalling certain model year 2015-2016 Chevrolet Silverado 2500 and 3500 heavy duty trucks manufactured October 1, 2013, to February 1, 2016, 2015-2016 Chevrolet Tahoe Police Pursuit Vehicles (PPV) manufactured March 1, 2014, to February 1, 2016, and 2015-2016 GMC Sierra 2500 and 3500 heavy duty trucks manufactured October 29, 2013, to February 1, 2016. On the affected vehicles, the brake pedal pivot nut may loosen, causing the brake pedal to be loose or inoperative. If the brake pedal becomes loose or inoperative, the driver may be unable to stop the vehicle by using the brake pedal. Additionally, a loose pedal may also interfere with the accelerator pedal. Either condition may increase the risk of a serious accident. GM will notify owners, and dealers will inspect the brake pedal pivot nuts, adding thread adhesive and tightening the nut as necessary, free of charge. The manufacturer has not yet provided a notification schedule. Owners may contact Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-800-462-8782. GM's number for this recall is 20760.
