On the 2018-2020 Buick Regal, 2018-2020 fifth-generation Regals (Sportback/TourX) were recalled because a software error in the electronic brake control module (EBCM) may fail to activate the hydraulic-brake boost backup if vacuum brake assist is lost. The result is a hard, high-effort brake pedal with substantially reduced braking performance and increased stopping distance. GM recalled roughly 23,734 vehicles (NHTSA 22V-xxx, July 2022).

Common Symptoms

  • Hard or stiff brake pedal
  • Increased pedal effort needed to stop
  • Longer stopping distances
  • Brake warning indicators

How to Fix

Dealers reprogram/update the EBCM software at no cost; no replacement parts required. Owners should verify the recall has been completed via VIN.
