Powertrain Warranty: Covers the engine, transmission, and other parts of the Drivetrain only, which is defined as the 29 parts of the vehicle through which oil flows.
These are the parts least likely to fail. The average vehicle contains thousands of parts. As it does not cover the majority of the components of a vehicle, the Powertrain Warranty is truly not a full extended warranty.
Bumper-to-Bumper Warranty: Covers nearly all of the mechanical systems of the vehicle, from front bumper to back bumper; except for those on the "exclusion list".
The "exclusion list" lists the parts that are NOT covered by the extended auto warranty. It is much easier for a consumer to see a short list of items that are not covered and know that everything else is.
Named Component Warranty: Covers the major mechanical systems of the vehicle from mechanical breakdown and mechanical failure. If the part is not listed, it's not covered by the contract.
NOTE: Consumable items, such as brake pads, clutch discs, radiator hoses or windshield wipers, are never covered. Roadside assistance and travel reimbursement plans are typically offered as part of the extended auto warranty package; even while the basic warranty is still in effect. Some even offer free lodging and meals if your vehicle breaks down on a trip.
