What is covered by the Optimum Used Vehicle Powertrain Limited Warranty?

Repair Coverage

General Motors will pay your General Motors Dealer the cost to remedy any covered failure of the components of your vehicle listed under the covered components section, except as explained in the items listed under the "What’s Not Covered By The Optimum Used Vehicles Powertrain Limited Warranty," and the "Additional Exclusions" sections located here .

A "failure" is defined as an original or like replacement part covered by this Powertrain Limited Warranty that does not function in normal service. To be covered, any failure must be repaired at a GM Dealer or a commercial repair facility of your choice using new or remanufactured replacement parts, unless we agree to do otherwise.

Subject to your deductible, we may either reimburse your out-of-pocket cost to repair or replace a covered part, or we may authorize and pay for the repair or replacement ourselves. In either event, we will authorize and pay the cost to remedy a covered failure of your vehicle, not to exceed the actual cash value of your vehicle at the time of the failure.

You are responsible for any charges incurred to determine the cause of the vehicle complaint; if it is determined that the complaint does not constitute a covered failure, you must pay for all diagnostic and associated costs. Covered repairs should normally be performed by the GM Dealer from whom you purchased your vehicle, or may be performed at the dealership of your choice.

Only covered mechanical failures occurring within Canada and the United States of America (including the continental United States, Alaska and Hawaii) are covered under the Optimum Used Vehicles Powertrain Limited Warranty.

Can I extend my warranty coverage?

If you prefer to extend this powertrain coverage or upgrade to the more comprehensive Optimum Used Vehicle Protection Plan, simply ask your dealer for details on different terms that better suit your driving needs. These upgrades are only available at the time of sale. All Optimum Used Vehicles Protection Plans provide coverage on parts and assembles that simply wearout. This means that if a covered part does wear out, we'll repair it.

If I sell my vehicle is the warranty transferable?

Yes, both the remaining Manufacturer's New Vehicle Limited Warranty and Optimum Used Vehicle Powertrain Limited Warranty coverage can be transferred to subsequent owners.

What must I do in the event of a covered failure?

In the event of a failure, you must:

Use reasonable means to protect your vehicle from additional damage.
Notify the Optimum Used Vehicle Dealer where you purchased or leased your vehicle or General Motors of Canada Limited, as soon as possible.
On weekends and holidays, or if you can’t contact a GM Dealer, you can call our toll-free claims hotline in Canada and the United States. Call 1-888-448-9888, between 9:00am and 5:00pm local time, seven days a week.
