A car warranty prices peace of mind to the owner of a vehicle. Most car warranties consist of several unique components, including bumper-to-bumper, power train, corrosion, roadside assistance and emissions warranties.

Bumper-to-Bumper Warranty

The bumper-to-bumper warranty covers all items on a vehicle other than wear items such as wiper blades and brake pads. Most bumper-to-bumper warranties are for three years or 36,000 miles, but luxury vehicles offer longer coverage.

Power train Warranty

The power train warranty covers sealed and lubricated components of the engine, transmission and drive axle. Power train coverage is backed by the manufacturer and is normally for a minimum of four years or 50,000 miles depending on the manufacturer.

Corrosion Warranty

All manufacturers offer some level of protection against vehicle rust-through. This warranty will be compromised if the rust on a vehicle is caused by body damage.

Roadside Assistance

Some manufacturers offer roadside assistance as a part of a new car warranty. Roadside assistance will pay to transport your vehicle to a dealership, change a tire or provide emergency fuel if you become stranded on the road.


Emissions warranties for new vehicles are mandated by the Environmental Protection Agency. All emission components are guaranteed for two years or 24,000 miles, and select major components are covered by an eight-year or 80,000-mile warranty. The specifics of the EPA warranty can be found in the second link under References below.
