What Happened
The vacuum power assist system in your Regal helps you control your brakes. In 2018-2020 models, a software glitch could cause this system to fail.
Risk if Unfixed
If the power brake assist fails, you'll need to press the brake pedal much harder to stop the vehicle. This could increase the distance you need to stop, making a crash more likely, especially on steep hills or when driving downhill.
Free Fix
Your Buick dealer will update the software controlling your brakes, ensuring it works properly. This repair is free of charge, and you should schedule it as soon as you get the recall notice.
