What's wrong?
The brake pedal pivot nut on affected 2015-2016 Chevrolet Silverado 1500, Silverado 2500, Silverado 3500, Tahoe Police Pursuit, Sierra 2500, and Sierra 3500 vehicles holds the pedal on its pivot bolt. That bolt is the hinge point that lets the brake pedal swing smoothly when the driver presses it.
On these vehicles, the nut was not always secured with the needed thread adhesive and torque after recall or later service work. Without that retention, normal pedal movement can loosen the nut over time. If the nut backs off, the brake pedal can feel loose or stop working as intended.
Drivers can notice a change in brake pedal feel before the part fails. The Service Engine Soon light can turn on, and the brake lights can stay on longer than expected after the driver releases the pedal.

What's the safety risk?
A loose or inoperative brake pedal can leave the driver unable to stop with the pedal, and a loose pedal can interfere with the accelerator. A change in pedal feel, Service Engine Soon light, or brake lights staying on longer than expected needs dealer attention. Repair is free at any franchised Chevrolet dealer.
What should I do?
- Check your VIN to confirm your 2015-2016 Chevrolet Silverado 1500, Silverado 2500, Silverado 3500, Tahoe Police Pursuit, GMC Sierra 2500, or GMC Sierra 3500 is included in this recall.
- Contact a franchised Chevrolet dealer to schedule the free brake-pedal pivot-nut repair that secures the loose or inoperative brake pedal.
- Bring the recall notice if Chevrolet sent one. If not, reference recall number 18V578 and GM recall 18278 when you call.
- Drive cautiously until the repair is complete. Leave extra following distance and avoid hard braking when traffic allows.
What happens at the repair
