WASHINGTON – General Motors is recalling more than 550,000 vehicles to address brake software problems which might result in a crash if not repaired, according to the National Highway Traffic Safety Administration.

In addition, in a separate action, the country’s largest auto maker is recalling more than 400,000 vehicles to remedy an electrical issue which might result in a fire.

Certain 2019 Chevrolet Silverado 1500, Cadillac CT6 and GMC Sierra 1500 models’ electronic brake control module (EBCM) might produce a software error which could result in the vehicles’ anti-lock brake system (ABS) and electronic stability control system (ESC) not functioning. Furthermore, if this specific error occurs, the vehicle’s diagnostics will not illuminate the instrument cluster ESC and ABS malfunction warning lights, thus the driver will not be aware of being without these safety features.

The recall is scheduled to begin in late January 2020. Dealers will reprogram the EBCM for free, which will solve the issue.

In addition, GM is recalling more than 400,000 2019/2020 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks because battery positive cable rings may have been manufactured with excessive glue, potentially resulting in a fire risk or stalling.

GM dealers will inspect vehicles for glue or other contamination and replace damaged components if necessary.

One fire has been reported and no injuries linked to the campaign. Some vehicles are covered by both recalls. The recall was prompted by a report of a stall by a GM employee in Canada.

The recalls, which are worldwide, cover more than 800,000 vehicles sold in the United States.
