Stewart v. General Motors

A proposed settlement of this national class action has been reached with General Motors with respect to the cost of repairs to certain General Motors vehicles as a result of the failure of nylon intake manifold gaskets, intake manifolds, upper intake manifold gaskets or throttle body gaskets (the “Settlement”).

Please visit for more details.

On October 14, 2008 the Ontario Superior Court of Justice in Toronto will determine whether to certify the class action for settlement purposes and to approve of the Settlement, including class counsel fees, and to inform potential class members of their rights. Notice of such hearing will be placed in various major newspapers across the Country on September 13, 2008. The Notice of Proposed Certification and Settlement Approval can be viewed here.

A similar hearing in Quebec will be scheduled shortly and a similar notice will be published in Quebec. A comparable settlement is proposed in the United States as well.

The proposed Settlement does not constitute any admission of liability by GM who denies the plaintiffs' allegations.

The Settlement proposes that individuals who own(ed) or lease(d) a Qualifying Vehicle (certain GM 1995-2004 model year vehicles), and who paid for a Qualifying Repair (Intake manifold gasket, intake manifold, upper intake manifold gasket, lower intake manifold gasket or throttle body gasket replacement or other related repairs) may be eligible to receive reimbursement for the Qualifying Repair as follows:

Age of Qualifying Vehicle at the Time the Qualifying Repair was Performed Maximum Amount of Reimbursement
1 to 5 years $400
6 years $100
7 years $50

As well, a class member who is eligible to receive cash payment in the 1-5 year category above may opt to instead receive 40% of the eligible repair expense, up to a maximum of $800, if the class member submits Proof of Internal Leak Repair Expense showing a repair costing over $1,500 due to a diagnosed internal coolant leak.

Should the court approve the settlement, a Final Notice of Certification and Settlement shall be published. At that point, class members will have until April 30, 2009 to submit a claim, which includes all necessary information and documentation as set out in Claim Form (Proof of Expenditure and Proof of Ownership), which will be posted on should the court approve the settlement. You will also have until November 30, 2008 to opt-out of the Settlement in order, for example, to pursue an individual claim against General Motors.

At the hearing on October 14, the Court will consider class members' objections to the proposed Settlement, including class counsel fees. Written objections must be mailed or emailed to the Claims Administrator and received no later than 5:00 p.m. on October 10, 2008 at the address listed below:

Overview and Summary of the Class Action

Koskie Minsky LLP, Colin Stevenson and Harvin Pitch act together for the plaintiffs in a proposed national class action against General Motors of Canada Limited and General Motors Corporation. The claim alleges that the defendants manufactured, in the 1995-2004 model years, motor vehicles with a defective intake manifold gasket (IMG).

The IMG regulates the flow of air and fuel into the cylinder. The allegation is that the IMG degrades prematurely causing coolant to leak into the engine. In particular, the plastic used to manufacture the IMG facilitated corrosion because it permitted leakage from the coolant system. The IMG did not properly seal the engine, causing leaks to occur. Among other consequences, the coolant mixes with engine oil making the oil ineffective and damaging the engine. In some cases engines overheat and seize completely, creating a danger to the operator and occupants and requiring complete engine replacements.

Plaintiffs' counsel has teamed up with counsel across the country to advance similar claims in most provinces.
