An express warranty is a specific promise made by a seller about the quality or performance of a product. This warranty can be communicated through written statements, advertisements, or verbal assurances. For example, if a company claims that a car can achieve 30 miles per gallon, that statement serves as an express warranty. If the product fails to meet the promised standards, the buyer may have the right to seek remedies, such as repairs or replacements. Express warranties are important because they help consumers make informed decisions and provide legal protection if the product does not perform as promised.
