This notice may affect your rights. Please read it carefully.


In 2006, seventeen (17) proposed class actions were commenced in Ontario, Alberta, British Columbia, Manitoba, New Brunswick, Newfoundland, Nova Scotia, Prince Edward Island, Quebec, and Saskatchewan alleging, inter alia, that the nylon intake manifold gaskets installed in certain General Motors Corporation and General Motors of Canada Limited (“GM”) vehicles were defective.

A settlement has been reached between the plaintiffs (the individuals who commenced the lawsuit) and GM, (the “Settlement”).  The members of the class affected by the Settlement are generally those who owned or leased certain GM vehicles, listed below, who incurred expenses for certain related repairs (“National Class Members”).  Please note that vehicles must be for personal, family, or household use, NOT for commercial or business purposes.

The Settlement has been approved by the Ontario Superior Court of Justice and the action has been certified as a class action by the Court for the purpose of effecting the Settlement.  The class counsel fees have been approved provisionally, subject to further order of the courts.

This Notice is to advise you of the certification of the class action for settlement purposes and the approval by the Court of the Settlement and to inform you of your rights as a Class Member.

The class action was certified for settlement purposes and the Settlement approved by Order of the Ontario Superior Court of Justice on October 20, 2008. The class counsel fees were approved provisionally, subject to further order of the courts.
