CONDITION

General Motors has decided that a defect which relates to motor vehicle safety exists in certain
2015-2016 model year Chevrolet Silverado and GMC Sierra 2500/3500 Heavy Duty Pickup
Trucks and Chevrolet Tahoe PPV (RPO 9C1) vehicles. The brake pedal pivot nut on these
vehicles may become loose, causing the brake pedal to be loose or inoperative. If the brake
pedal becomes loose or inoperative, the driver may be unable to safely stop the vehicle through

application of the brake pedal, increasing the risk of a crash. A loose pedal may also interfere
with the accelerator pedal, increasing the risk of a crash.

CORRECTION

Dealers are to inspect the pivot bolt installation to determine whether the vehicle has already
received the production remedy. If not, dealer will add adhesive to the nut, and reinstall the nut
at an increased torque.
