General Motors Brake Booster Pump Investigation

Experienced Brake Failure in Your Chevrolet Equinox, GMC Terrain, or Buick Envision?

Clarkson Law Firm is investigating numerous complaints regarding brake failure caused by defective brake booster pumps in Chevrolet Equinox, GMC Terrain, and Buick Envision vehicles manufactured and sold by General Motors, LLC. Vehicle owners have reported that these pump failures result in hard brake pedals, reduced braking power, and hazardous driving conditions, creating significant safety risks for drivers and passengers.

Despite knowing about the widespread brake problems, General Motors has failed to take adequate action, placing customer safety at risk and leaving them to bear the cost of expensive repairs. Many owners report paying thousands of dollars for booster pump replacements and engine repairs from exploding brake booster pumps, with no reimbursement from General Motors.

Have you been affected?
Owners of the following vehicles have widely reported brake booster pump failures that result in extremely hard brake pedals and loss of braking power, indicating a systemic defect:
  • 2018-2024 Chevrolet Equinox
  • 2018-2024 GMC Terrain
  • 2017-2021 Buick Envision
Yet, General Motors has failed to adequately address the problem. If you've experienced these brake failures, you're not alone—and you may be entitled to compensation.
