Oh boy, General Motors is heading back to court. This time, the problem isn’t related to faulty engines or failing transmissions. The class-action involves alleged brake problems that impact SUVs across multiple brands. 

General Motors faces brake booster problem lawsuit 

A new class action lawsuit claims that multiple General Motors SUVs have a dangerous braking defect. Reportedly, vacuum pump failures lead to hard brake pedals. As a result, it causes extended stopping distances and total brake failure. 

Drivers share that the pedals are impossible to push. As a result, some SUV owners have to cut the ignition in order to stop. 

According to CarComplaints, the lawsuit includes: 

  • 2016-2020 Buick Envision 
  • 2018-2022 Chevrolet Equinox 
  • 2018-2022 GMC Terrain 

In 2019, General Motors issued a recall for 3.4 million vehicles due to brake booster problems that caused the loss of power brakes. However, the vehicles in the lawsuit weren’t included. 

But the plaintiffs share examples of how their SUVs lost braking power in traffic. Then, mechanics determined the failure was related to metal shards from exploded vacuum pumps inside the engine. 

This is the exact same problem that led to the massive recall. However, General Motors refused to cover the repair costs. Plus, the plaintiffs claim that GM was aware of these SUVs having a defective brake booster and sold them anyway. 

Allegedly, GM quietly redesigned the brake booster vacuum system for 2023 models of the Chevy Equinox and GMC Terrain to correct the defect. Signs of brake failure may include a hissing noise, a spongy pedal, a pedal that’s hard to press, or a pedal that sticks to the floorboard.
