A vehicle warranty is a guarantee that a vehicle manufacturer or dealer makes to the buyer, promising to repair or replace any defects in the vehicle that arise during a specific period of time, typically 3 years or 30,000 miles. The warranty generally covers the cost of parts and labor necessary to repair the car, with some restrictions and limitations. Vehicle warranties are often included when purchasing new or certified pre-owned vehicles, but they can also be purchased separately from third-party providers as extended vehicle warranties for used cars. They offer peace of mind to the buyer, ensuring that any unexpected issues with the vehicle will be handled at no extra cost.
