Warranties are a significant source of consumer protection. Warranties are also important to the law of product liability, which concerns the liability of manufacturers and merchants for injuries caused by defective products. A warranty is a promise made by the manufacturer or seller of a product that guarantees some aspect of the product. This guarantee is limited in scope and duration. An express warranty is a warranty explicitly given by the manufacturer or seller.
Express warranties are terms that usually go to the essence of the contract.
There are several ways to make an express warranty, but the most common way is to make a written or oral representation of fact or promise. The implied warranty means that the product will work the way it is supposed to work. Implied warranties mean that the product is not defective at the time of sale. The implied warranty is also called the implied warranty of merchantability. Unlike the express warranty, the implied warranty arises silently by virtue of the transaction itself.
