Car warranties generally cover the repair or replacement of malfunctioning or damaged parts, but they do not pay for maintenance services and car breakdowns resulting from accidents, neglect, acts of nature, theft or liquid contamination, explains NerdWallet. A bumper-to-bumper car warranty covers repairs associated with defective factory-installed vehicle parts, while a drivetrain warranty pays for transaxle, transmission and engine repairs.
A federal emission warranty covers costs for repairs of faulty parts that would otherwise fail to comply with Environmental Protection Agency standards if not fixed, states NerdWallet. Roadside assistance warranties cover repair costs related to towing and changing tires while traveling. A rust or corrosion warranty pays for repair costs associated with rusty sheet metal parts.
Manufacturers and dealers offer car warranties for a specific period and mileage, usually for three years or 36,000 miles, notes NerdWallet. When buying a car warranty, car owners should consider the length and limitations of the warranty and the types of parts and repairs covered.
To keep a warranty valid, it is important to perform regular maintenance, such as fluid checks, tire rotations and oil changes, advises NerdWallet. Car owners may use the dealer's service department or choose their own mechanic when seeking repairs. When a car warranty expires, car owners have the option to buy a service contract, also called an extended warranty, for coverage for repairs.
