Basic Warranty
The basic warranty is the initial warranty provided for new cars. All factory installed components are covered. The initial “bumper-to-bumper” warranty provides the best and most comprehensive coverage.

Powertrain Warranty
A powertrain warranty only covers a small portion of the vehicle – specifically that portion that provides power to the vehicle from the engine to the axles. This usually includes the Engine (Cylinder block and head and all internal parts, timing belt and cover, flywheel, oil pan, water pump, fuel pump, engine mounts, engine control computer, seals and gaskets), Transmission and Transaxle (Case and all internal parts, torque converter, clutch cover, mounts, engine control computer, seals and gaskets), and Drive System (Driveshafts, axle, hub, bearings, seals and gaskets, differential carrier assembly, driveshaft, axle carrier, axle case, axle bearing, axle shaft, seals and gaskets.)

Manufacturers offer other warranties on new vehicles. Some examples include:

Federal Emissions Warranty
Federally required emission control warranties protect you, the vehicle owner, from the cost of repairs for certain emission related failures that result from manufacturer defects in materials and workmanship or that cause your vehicle to exceed federal emission standards. Manufacturers have been required by federal law to provide emission control coverage for vehicles since 1972. There are two federal emission control warranties discussed in this fact sheet: (A) "Performance Warranty" and (B) "Design and Defect Warranty". This fact sheet explains each warranty in detail, provides you with a list of some of the parts covered under these warranties, explains the procedures for making an emissions warranty claim, and answers some of the most commonly asked questions about emissions warranties. Finally, we will give you some tips on how to prevent future emission-related failures and maintain the longevity of your vehicle's engine.  

A. PERFORMANCE WARRANTY   The Performance Warranty covers repairs which are required during the first 2 years or 24,000 miles of vehicle use because the vehicle failed an emission test. Specified major emission control components are covered for the first 8 years or 80,000 miles. If you are a resident of an area with an Inspection and Maintenance (I/M) program that meets federal guidelines, you are eligible for this warranty protection provided that:   * Your car or light-duty truck fails an approved emissions test; and   * Your vehicle is less than 2 years old and has less than 24,000 miles (up to 8 years/80,000 miles for certain components); and   * Your state or local government requires that you repair the vehicle; and   * The test failure does not result from misuse of the vehicle or a failure to follow the manufacturers' written maintenance instructions; and   * You present the vehicle to a warranty-authorized manufacturer representative, along with evidence of the emission test failure, during the warranty period.   During the first 2 years/24,000 miles, the Performance Warranty covers any repair or adjustment which is necessary to make your vehicle pass an approved, locally-required emission test and as long as your vehicle has not exceeded the warranty time or mileage limitations and has been properly maintained according to the manufacturer's specifications.    

B. DESIGN AND DEFECT WARRANTY   The Design and Defect Warranty covers repair of emission related parts which become defective during the warranty period. The Design and Defect warranty for model year 1995 and newer light-duty cars and trucks is outlined below:   Design and Defect Warranty Coverage for 1995 and newer light-duty vehicles:   * Emission control and emission related parts are covered for the first 2 years or 24,000 miles of vehicle use; and   * Specified major emission control components are covered for the first 8 years or 80,000 miles of vehicle use.

Corrosion Warranty
A Corrosion Warranty covers protection against rust-through on the metal of your car. Corrosion protection is limited, and many causes are not covered.
