The power brake assist system in your Buick Regal helps you slow down or stop the vehicle by amplifying the force of your brake pedal. This system relies on a computer and vacuum power to work correctly.
Risk if Unfixed
If the computer system fails, you'll lose power brake assist, which means you'll have to press the brake pedal much harder to stop the vehicle. This could take longer to stop, increasing the risk of a crash.
Free Fix
Your Buick dealer will update the computer software that controls the power brake assist system, and this repair is completely free. You should schedule the update as soon as you get the recall notice to ensure your safety on the road.

What Happened
The brake caliper in your vehicle is a crucial part that helps your rear brakes function properly. In some 2018-2019 models, the coating on the caliper pistons might not be enough, which could cause air pockets to form and reduce your brake performance.
Risk if Unfixed
If your rear brakes don't perform well, you could lose stopping power, especially when driving at high speeds or on slippery roads. This could increase the risk of a crash.
Free Fix
Your dealer will bleed the brake system to ensure it's functioning properly, and this service is free of charge. You'll receive a notification when the repair is ready.
