Service Brakes, Hydraulic:power Assist:electric:control Module:software 2022-06-30 · campaign 22V465000 · 23,734 vehicles
Defect: General Motors, LLC (GM) is recalling certain 2018-2020 Buick Regal vehicles. In the event of a vacuum-power brake assist failure, a software error in the electronic brake control module (EBCM) may result in a loss of power brake assist. As such, these vehicles fail to conform to Federal Motor Vehicle Safety Standard No. 135, "Light vehicle brake systems."
Risk: A loss of power brake assist can extend the distance required to stop the vehicle, increasing the risk of a crash.
Fix: Dealers will update the EBCM software, free of charge. Interim owner notification letters advising owners of the safety risk were mailed on August 19, 2022. Owner notification letters were mailed September 16, 2022. Owners may contact Buick's customer service at 1-800-521-7300.
