Buick Regal Recalled for Brake Issues

A software problem may increase braking distance in some situations

Buick is recalling nearly 24,000 Regal sedans, Regal Sportback hatchbacks, and Regal TourX wagons from the 2018 through 2020 model years because a software error could make braking more difficult.

If the vehicle’s vacuum-power brake assist fails, the supplemental hydraulic brake boost may not engage. This could increase stopping distances and require additional pressure on the brake pedal, and may result in a crash.

In documents provided to the National Highway Traffic Safety Administration, Buick says it is not aware of any crashes or injuries related to this recall, but that there have been at least four reports from owners about poor braking performance.

In order to fix the problem, Buick dealerships will perform software updates on the affected vehicles, free of charge.

Vehicles recalled: Buick Regal, Regal Sportback, and Regal TourX vehicles manufactured between June 9, 2017, and July 1, 2020

The problem: A software error means the vehicle’s electronic brake control module may not activate a supplemental hydraulic brake boost if the vacuum-brake assist fails.

The fix: Buick dealerships will update the software, free of charge.

How to contact the manufacturer: Buick will start notifying owners of affected vehicles by mail starting Aug. 15, 2022. Owners may also contact Buick at 800-521-7300.

NHTSA campaign number: 22V465

Check to see whether your vehicle has an open recall: NHTSA’s website will tell you whether your vehicle has any open recalls that need to be addressed.

If you plug your car’s 17-digit vehicle identification number (VIN) into NHTSA’s website and a recall doesn’t appear, it means your vehicle doesn’t currently have any open recalls. Because automakers issue recalls often, and for many older vehicles, we recommend checking back regularly to see whether your vehicle has had a recall issued.
