The 2020 Buick Regal has two recalls, the more serious being a brake software issue where a failure in the vacuum brake assist system can cause the electronic brake control module to lose power assist entirely, extending stopping distances.
The front seat frames are also affected: the lower crossbar on driver or passenger seats may have been improperly welded, meaning the seat may not hold up properly in a crash and could increase the risk of injury to the occupant.
