What's wrong?
The front brake caliper on a 2015 Canyon or Colorado truck is the metal brake part mounted at each front wheel. When you press the brake pedal, hydraulic pressure moves through the brake fluid and forces the caliper to squeeze the brake pads against the rotor. That squeeze is what slows the truck.
On affected trucks, the front caliper body has air pockets in the metal casting. Those pockets are an imperfection in the caliper body, and they leave the part unable to hold brake fluid as designed. Brake fluid leaks from the caliper, which lowers the pressure the brake system needs to clamp the pads with full force.
There is no warning sign before failure. Do not rely on a pedal change, noise, or visible fluid to decide whether the truck is included.
Who's affected?
Both midsize pickup lines involve the same hydraulic brake system.
| 2015 GMC Canyon | hydraulic brake system |
|---|---|
| 2015 Chevrolet Colorado | hydraulic brake system |
| Units affected | 24,380 |
A matching 2015 Canyon or Colorado does not guarantee inclusion. Check your VIN to confirm whether your specific pickup truck is included.
What's the safety risk?
A brake fluid leak can lengthen stopping distance and increase the risk of a crash. Drive cautiously, leave extra room to stop, and arrange the recall inspection as soon as the repair path is open. Repair will be free at any franchised GMC dealer once available.
What should I do?
- Check your VIN to confirm your 2015 Canyon or Colorado truck is included in this recall.
- Contact a franchised GMC dealer to ask about the free front-brake-caliper inspection and replacement for brake-fluid leaks.
- Bring the recall notice if GM mailed one. If not, reference recall number 15V278 when you call.
- Drive cautiously until the repair is complete. Leave extra following distance and avoid hard braking.
What happens at the repair
At the dealer, a GMC technician inspects the front-brake calipers for brake-fluid leakage tied to air pockets or an imperfection in the metal caliper body. The technician replaces any front-brake calipers that fail inspection. The dealer repair will be free once available, with parts and labor covered under recall 15V278. Ask the service desk to confirm the inspection and replacement steps when you schedule the visit.

Frequently asked questions
What is recall 15V278?
Recall 15V278 covers 24,380 2015 GMC Canyon and Chevrolet Colorado trucks with front brake calipers that can leak brake fluid because of air pockets in the metal caliper body. The leak can increase stopping distance and crash risk. Dealers inspect and replace affected front brake calipers for free.
What should I do if my 2015 GMC Canyon or Chevrolet Colorado is on this recall?
Check your VIN to confirm your specific truck is included in recall 15V278. If it is, contact a franchised GMC or Chevrolet dealer to schedule the front brake caliper inspection. Reference recall number 14888 when you call. The inspection and needed caliper replacement are free.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the defect at no cost, and GM dealers inspect and replace the affected front brake calipers free of charge. The free repair applies even if you bought the truck used.
What is the safety risk?
The safety risk is longer stopping distance from a front brake fluid leak. If the caliper leaks, the truck needs more distance to stop, increasing crash risk. Use the VIN check first, then schedule the free dealer inspection and repair if your truck is included.
What if I bought my GMC Canyon or Chevrolet Colorado used?
The free recall repair still applies. Recall coverage follows the VIN, not the original owner. Check your VIN to confirm whether your specific truck is included in recall 15V278, then call a franchised GMC or Chevrolet dealer and reference recall number 14888.
