Manufacturer Warranties

This is an example of Chevrolet's manufacturer's warranty
What is the 100,000 mile/5-year Powertrain warranty?

All Chevrolet cars and trucks are covered. The Powertrain Limited Warranty is 100,000 miles or 5-years which only covers the powertrain. This would be the engine, transmission and drive train.  All other componets on the vehicle are not covered under this warranty. In addition, the Roadside Assistance and Courtesy Transportation programs are also 100,000 miles or 5-years (whichever comes first). 

How is the bumper-to-bumper warranty affected by this 100,000 mile/5-year warranty?

The bumper-to-bumper New Vehicle Limited Warranty on new GM cars and light-duty trucks remains in effect for 3 years or 36,000 miles (whichever comes first, see dealer for details) on Chevrolet and GMC vehicles; and 4 years or 50,000 miles (whichever comes first, see dealer for details) on Buick and Cadillac vehicles. The powertrain limited warranty supplements the bumper to bumper warranty and, in general, continues to cover the engine, transmission, transfer case and axle assemblies on light duty vehicles up to the 5 years or 100,000 miles.

The bumper-to-bumper warranty and what it covers

The Bumper-to-Bumper Limited Warranty covers Chevrolet cars and trucks for  3 years or 36,000 miles (whichever occurs first); and 4 years or 50,000 miles (whichever occurs first) on Buick and Cadillac vehicles. It covers just about all mechanical compents on the vehicle against mechanical defects. Original tires are covered but prorated after 12,000 miles during the terms of the Bumper to Bumper Limited Warranty. For further details go to for more information.

Is my vehicle covered from rust, too?

Chevrolet vehicles are designed and built to resist corrosion. The warranty for body and sheet metal components against rust-through corrosion is for a minimum of 6 years/100,000 miles (whichever comes first). Application of additional rust-inhibiting materials is not required under the corrosion coverage and none is recommended.
