Hagens Berman is investigating a hazardous brake defect affecting hundreds of thousands of Toyota vehicles that reportedly causes the vehicle's braking system to completely fail, leading to high risk of crash, injury and potential fatality. The defect is believed to stem from the vehicles' brake booster pump assemblies, which a Toyota dealership owner reportedly has stated is "causing crashes that are injuring people," adding that "Toyota is mishandling it."

The defect manifests even in new, or almost new vehicles, and drivers report the instance of the defect especially when attempting to brake while traversing bumpy or slick surfaces such as potholes, metal sheets or ice, but reports to the National Highway Traffic Safety Administration (NHTSA) also document the defect in many various other conditions, leading to crashes and injuries.

Owners report that the defect essentially renders their brakes inoperative under normal driving conditions.


Toyota owners have detailed instances of brake failure and crashes in reports to the NHTSA:

  • "My brakes consistently lock and the car lunges forward...This caused a crash when the car was only a couple years old when the brakes failed to stop the vehicle and it lunged forward into the back of a car. This is extremely dangerous and I've seen this comment often with this vehicle. I don't understand why Toyota has not addressed this issue."
  • “Driving vehicle down highway, tapped brakes but brakes did not work, all the lights on my dash lit up. I lost traction in brakes causing vehicle to lose control."
  • "When the brakes are pressed, if you hit a bump or pothole, the brakes lock and the car hydroplanes..."
  • "...I had no control over the car or the speed. This is [sic] major safety hazard since someone could have been seriously injured with losing control of the brake and acceleration."
  • "Car lurches forward when brakes are applied on bumpy of uneven surfaces, as well as slippery surfaces such as metal plates...It's scary and I feel lucky I haven't hit anyone."
  • "...scared daily by the unsafe driving conditions due to the car's tendency to lurch forward while braking over bumpy ground or potholes..."


After several years of dodging, Toyota extended warranty to vehicles experiencing the defect, but only by way of certain “diagnostic trouble codes” registered by the automobile. Toyota is aware that the defect will cause at least some percentage of brake systems to fail, but instead of issuing a recall and replacing the braking systems in the affected vehicles, Toyota has chosen to respond to this potentially life-threatening defect in a piecemeal and hazardous manner, instead waiting for drivers to experience it before it will offer even a marginal remedy. It is knowingly allowing hundreds of thousands of drivers to continue operating cars containing a defective brake system.

Hagens Berman believes vehicle owners deserve more, and that Toyota should be held accountable for selling a defective product for which owners paid a premium price. While Toyota would rather wait until they are forced to act, we think those affected by this issue should receive immediate help.


Hagens Berman is one of the most successful auto litigation law firms in the U.S. The firm has achieved many of the largest settlements in automotive class-action lawsuits on behalf of vehicle owners, including what was at the time the largest automotive settlement in history against Toyota – $1.7 billion for a defect causing sudden, unintended vehicle acceleration. Your claim will be handled by attorneys experienced in automotive consumer law.


There is no out-of-pocket cost or fee to join this case. In the event Hagens Berman or any other firm obtains a settlement that provides benefits to class members, the court will determine and award reasonable fees and costs to the class’s legal team.
