Defect description
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."
Safety risk
A loss of power brake assist can extend the distance required to stop the vehicle, increasing the risk of a crash.
Manufacturer remedy
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.

Safety risk

Manufacturer remedy
GM will notify owners, and dealers will inspect the crossbar welds on the front seats. If the crossbar is improperly welded, the seat back frame will be replaced, free of charge. Interim notices informing owners of the safety risk were mailed November 26, 2019. Owners received a second notice and the recall began February 20, 2020. Owners may contact Buick customer service at 1-800-521-7300. GM's number for this recall is N192278300.
