A warranty is a specialized service under which a product manufacturer assures to service and maintain the product for a specified period of time from the date of its sale. This service is aimed to maintain goodwill with the customer apart from providing value for money. During the warranty period, if there are any manufacturing defects in the product, the defects will be rectified. If the products are minor consumer care appliances, they may be even replaced by the manufacturer. All consumer products carry a warranty. Even automobiles come with some sort of  warranty. The warranty for cars and vehicles is called auto warranty.

The auto warranty, which is issued up to a maximum of three years, is of two categories. They are used car warranty and new car warranty. The used car warranty is given to used cars or preowned cars. The used car warranty is also called as after-market auto warranty. The new car warranty is issued to brand new cars released from the showrooms. Both, new car warranty and used car warranty, is offered by the auto dealer on behalf of the vehicle manufacturer. The services under auto warranty are rendered by the auto dealer periodically in association with a third party agent, which has nationwide presence.
