Plain-English summary

General Motors, LLC is recalling certain 2018-2020 Buick Regal vehicles. The recall addresses a software error in the electronic brake control module (EBCM) that may result in a loss of power brake assist if a vacuum-power brake assist failure occurs. As a result, these vehicles fail to conform to Federal Motor Vehicle Safety Standard No. 135, "Light vehicle brake systems."

A loss of power brake assist can extend the distance required to stop the vehicle, which increases the risk of a crash. The source text does not report any specific injuries or fatalities associated with this defect.

Dealers will update the EBCM software free of charge. Interim owner notification letters were mailed on August 19, 2022, and final owner notification letters were mailed on September 16, 2022.
