General Motors (GM) offers warranties on all new vehicles sold under its various marques (Chevrolet, Cadillac, Buick, GMC.) There is also various warranty protections for some used cars sold by GM Certified dealers. The difference in warranties is simply how much of the vehicle’s various components are covered for any given time. As the mileage and the car’s age increases, warranties cover less until finally expiring. Know what is covered and for how long let’s the owner know not only what will get repaired in the event of problems but also how to budget maintenance costs as the vehicle age.

GM’s new car warranties come in three types: Bumper-to-Bumper (meaning the entire car), power train (engine, transmission, suspension) and sheetmetal (the body work.) Each of the four brands has different mileage/time limits on the different warranty coverage.

GM also offers extended warranties that go beyond the coverage provided with the car’s purchase price. The extended warranty coverage covers the same three sections of the car but at costs based on the vehicle’s age, mileage and model. The GMPP (General Motors Protection Plan) not only extends the warranty protection for the vehicle but also provides for warranty-covered work at all GM certified dealers worldwide.

An example of the extended coverage is Chevrolet’s warranty offers. New vehicles come with 36 month/36,000 mile (whichever comes first) warranties and the GMPP can extend that coverage for up to 72 months and 100,000 miles. Body corrosion coverage for the Chevys are also 36/36 and can also be increased to 72/100. Drivetrain warranties are available for all makes of GM vehicles and can be extended for the life of the car (at ongoing renewal pricing.) This would cover the engine block, the transmission gearbox for manual and automatics, the differential gear and fuel system. Brakes, tires and wheels are excluded from these warranties. These extended warranties can also include 24-hour roadside assistance and alternative transportation options while the vehicle is receiving warranty work.

Finally, if considering an extended warranty for a GM vehicle, it is important to know the difference between an extended warranty and a service contract. Many dealers (both GM Certified and others) offer service contract. A service contract is a predetermined agreement for service costs the buyer pays for in advance. What the services agreement covers is detailed before purchase. A service contract, however, is not an extended warranty. The service contract is only applicable to that particular dealer or dealers specified in the contract. A GMPP extended warranty is honored at all GM-Certified maintenance providers.
