What's wrong?
The electronic brake control module on affected 2019 Silverado 1500 and Sierra 1500 trucks is the computer that manages brake assist, antilock braking, and electronic stability control. When it works correctly, it helps the hydraulic brake system apply assisted braking force and helps the truck stay stable during braking or loss-of-traction events.
These trucks received updated EBCM software from a prior dealer repair. That software contained an error, so the truck's electronic brake assist is disabled after ignition while the truck is stationary. The corrected software removes the error that caused the brake-assist problem and the related safety-standard noncompliance.
Owners will see clear warning signs when the condition is present. The antilock brake, brake, and electronic stability control warning lamps illuminate, and the driver information center displays messages such as "Service Brake Assist," "Service ESC," and "Brake System Failure."
Who's affected?
Covers the Silverado 1500 and Sierra 1500 under the same hydraulic brake system component.

|---|---|
| 2019 GMC Sierra 1500 | hydraulic brake system |
| Units affected | 148,055 |
| Field incidents | NHTSA has logged no field incidents to date. |
A matching 2019 Silverado 1500 or Sierra 1500 does not guarantee inclusion. Check your VIN to confirm whether your specific pickup truck is included.
What's the safety risk?
Loss of electronic brake assist can increase crash risk because the driver has less brake assistance than expected. This condition occurs only when the vehicle is stationary at ignition, and the vehicle displays brake, antilock brake, and stability control warnings, including "Service Brake Assist" and "Brake System Failure." If those warnings appear, schedule the dealer repair soon. Repair is free at any franchised Chevrolet dealer.
What should I do?
- Check your VIN to confirm your 2019 Chevrolet Silverado 1500 or Sierra 1500 is included in this recall.
- Contact a franchised Chevrolet dealer to schedule the free EBCM reprogramming that restores electronic brake assist.
- Bring the recall notice if you have it, and reference recall number 20V055 when you call.
- Drive cautiously until the EBCM software update is complete. Leave extra following distance and allow more room for braking.
- Call Chevrolet customer service at 1-800-222-1020 with questions about scheduling or dealer availability.
What happens at the repair
At the dealer, a Chevrolet technician reprograms the Electronic Brake Control Module (EBCM) to correct the software error that disables electronic brake assist. The software update and labor are covered under the recall, so the dealer visit is free. Out-of-pocket repairs already paid are handled through the vehicle's existing warranty, not through a separate reimbursement program, because the covered vehicles are under warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
