General Motors Diesel Emissions - Sotos Class Actions

GM Diesel Emissions

This case alleges that the defendant car manufacturers unlawfully installed hidden devices (called “defeat devices”) in the cars that they sold to the public.

The defeat devices allegedly shut down the cars’ emission control systems outside regulatory testing circumstances. As such, the cars were able to pass emission tests but polluted excessively when driven on the road.

The manufacturer defendants in the action are General Motors companies. Bosch and its related companies are also defendants that supplied the vehicles’ engine control computers that allegedly housed the defeat devices.

The Plaintiffs allege that the defendants’ conduct breached Canadian environmental, consumer protection, and other laws.

The Court will decide at a later date if the cases will proceed as class actions.

The case seeks to represent all persons in Canada who purchased or leased any of the following diesel vehicles:

  • GMC Sierra 2500HD and 3500HD (model years 2011-2016);
  • Chevrolet Silverado 2500HD and 3500HD (model years 2011-2016); and
  • Chevrolet Cruze (model years 2014-2015).
