GM Diesel Emissions Overview

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).

Cette action allègue que les défendeurs qui sont des constructeurs automobiles ont illégalement installé des dispositifs dissimulés (appelés « dispositifs de manipulation » ou « dispositifs de mise en échec ») dans les véhicules qu’ils ont vendus au public.

Il est allégué que les dispositifs de manipulation arrêtaient les dispositifs antipollution des véhicules en dehors de circonstances d’essais réglementaires. Ainsi, les véhicules étaient en mesure de réussir les essais effectués pour mesurer les émissions, mais polluaient excessivement lorsqu’ils étaient conduits sur route.

Les constructeurs qui sont défendeurs dans cette poursuite sont les entreprises General Motors,.Bosch et ses filiales sont également des défendeurs, car ils ont fourni les ordinateurs de gestion de moteur des véhicules qui ont prétendument abrité les dispositifs de manipulation.

Les demandeurs allèguent que le comportement des défendeurs a enfreint les lois canadiennes en matière de protection environnementale, de protection des consommateurs, et d’autres lois.

Le tribunal décidera ultérieurement si les causes iront de l’avant comme recours collectifs.

La poursuite vise à représenter toutes les personnes au Canada qui ont acheté ou loué l’un des véhicules diésel suivants :

  • GMC Sierra 2500HD et 3500HD (modèles 2011 à 2016);

Frequently Asked Questions

A class action is a special form of lawsuit in which one plaintiff brings a claim against one or more defendants based on allegations which are common to a group, or class, of people. In order for the action to become a class action, it must proceed through a stage known as “certification”.

A statement of claim is issued on behalf of a “representative plaintiff”. The representative plaintiff’s role is to work with class counsel to bring the action forward and to represent the class members in court.

In order for an action to proceed on behalf of the entire class, a judge must decide (among other things) whether the members of the proposed class have common issues, and whether a class action is the preferred way to resolve the issues. The process to decide these issues is known as the “certification motion”. If the judge is satisfied that the case meets all of the requirements for certification, he or she will issue an order which certifies the action as a class action.

No. If the lawsuit is certified, and you are included in the class as defined, you are automatically included in the lawsuit.

No. We will work primarily with the class representative.

Those who do not wish to remain in the class will be given the option to opt-out by sending an opt-out form at the appropriate time to us.

Certification as a class action will enable us to prove the facts in a single lawsuit rather than in numerous individual lawsuits. This has obvious benefits to the class members and to the courts.

There is no timeframe. We will move the case forward diligently but it can take a considerable period of time to reach trial.

Many class actions settle and thereby remove the need for a trial. However, we cannot predict with any certainty whether or not there will be a settlement in a given action.

The chances of “winning” can never be accurately predicted.

Class action lawsuits are typically brought on a contingency fee basis. This means that the lawyers will only be paid if the action is successful at trial or results in a settlement in favour of the plaintiffs. Legal fees would then be paid out of the settlement or judgment proceeds as approved by a judge.

Disbursements (i.e. out-of-pocket expenses, including expert reports) may be dealt with in one of two ways.

Most commonly, the lawyers will absorb the cost of disbursements. The lawyers may seek funding assistance from the Class Proceeding Fund, which may provide funding for disbursements if granted.

In some cases, disbursements may be funded by the class members, including the class representative. This typically occurs in smaller class actions brought on behalf of an organization or network of individuals where each member of the class is easily identifiable and known to the representative plaintiff. If the class action is successful, amounts advanced for disbursements are re-paid from the proceeds of any judgment or settlement to class members (and others).

Only the class representative may be liable for costs of the common issues portion of the action if it is unsuccessful.

A “payout” or an award for damages is never certain.

The action may settle or it may proceed to trial, at which time a judge will determine the amount of damages, if any, to which the class members are entitled to. Regardless, the amount of “payout” cannot be predicted, and we cannot predict when the action may settle or when the trial will conclude.

If the lawsuit is certified as a class action, you will receive a formal notice from the court explaining the nature of the case and providing you with the opportunity to opt out if you wish. General information about the lawsuit will be posted on Sotos LLP’s website at

We ask that you keep a copy of any documents, correspondences, records, invoices, receipts, etc. that you feel might be relevant to your individual claim in the class action. If there is a “payout,” this documentation may be required in order to support your claim for compensation.

It is not required that you send any documents to us at this time.
