Is A GM Extended Warranty Worth It?

Extended warranties provide value to customers by protecting against the cost of sudden and unexpected repairs. When considering GM extended warranty coverage, think about the reliability of your vehicle and the protection already offered by your factory warranty.

Are GM Cars Reliable?

GM brands vary in reliability based on industry studies, so be sure to research your vehicle. Described below are some GM vehicles, RepairPal reliability ratings, and average annual repair costs, according to RepairPal.

GM Factory Warranty

If you don’t intend to own your car for very long before you trade it in, it may not be worth purchasing an extended warranty. While an extended warranty can increase resale value on the open market, it will not increase trade-in value at the dealership.

All GM vehicles are protected by a bumper-to-bumper warranty and a powertrain warranty. Some have additional warranties for hybrid components and emissions parts.

GM Bumper-To-Bumper Warranty

Bumper-to-bumper warranties cover most vehicle parts with the exception of wear-and-tear items like brake pads and wiper blades. A GM Extended Limited Warranty is an extension of the bumper-to-bumper warranty.

GM Powertrain Warranty

A powertrain warranty covers the engine parts that make the car move like the engine, transfer case, and transaxle. For Chevy, Buick, and GMC brands, the powertrain warranty lasts for 5 years/60,000 miles. For Cadillacs, powertrain coverage extends to 6 years/70,000 miles.

Best Place To Buy A GM Extended Warranty

Third-party warranties are one alternative to factory coverage. While vehicle service contracts are not always as comprehensive as manufacturer’s coverage, they do offer more flexible options such as a choice of repair shop, longer coverage terms, more perks, and coverage for older vehicles.
