General Motors is recalling 23,734 model year 2018-2020 Buick Regals.
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.
A loss of power brake assist can extend the distance required to stop the vehicle, increasing the risk of a crash.
What to do
Dealers will update the EBCM software free of charge.
Owner notification letters are expected to be mailed on August 15, 2022.
Owners may contact Buick's customer service at (800) 521-7300.
