The short answer

NHTSA received General Motors, LLC’s report on Jun 30, 2022. Copied from NHTSA on Oct 19, 2026.

Every line below is in NHTSA’s own words, with its source beside it.

What’s wrong with it?

A loss of power brake assist can extend the distance required to stop the vehicle, increasing the risk of a crash.

General Motors, LLC (GM) is recalling certain 2018-2020 Buick Regal vehicles.

In the event of a vacuum-power brake assist failure, a software error in the electronic brake control module (EBCM) may result in a loss of power brake assist.

As such, these vehicles fail to conform to Federal Motor Vehicle Safety Standard No. 135, “Light vehicle brake systems.”

What the record doesn’t say

  • NHTSA’s recall file doesn’t say whether anyone was hurt. Owners’ complaints are counted on each vehicle’s page.
  • Whether one vehicle or seat has been fixed: only its maker, or NHTSA’s lookup with a VIN, can say.
  • How many have been returned or fixed isn’t in the notice.
