What this recall means for you
Certain 2018-2020 Buick Regal vehicles may lose power brake assist if the vacuum-powered brake assist fails. A software error in the electronic brake control module can prevent the system from responding properly, so the brakes may need more effort and the vehicle may take longer to stop.
A loss of power brake assist can extend the distance needed to stop, which raises the risk of a crash. Owners should be aware of this risk and avoid delaying the repair.
The remedy is a free software update to the electronic brake control module, performed by an authorized Buick dealer. Owners can call Buick customer service at 1-800-521-7300 with questions, and should check their vehicle identification number (VIN) for open recalls.
