Warranty law refers to the legal principles that govern the promises made by sellers regarding the quality and performance of their products. These warranties can be either express, where specific guarantees are stated, or implied, which are automatically included by law based on the nature of the transaction. When a product fails to meet the warranty terms, consumers have the right to seek remedies, such as repairs, replacements, or refunds. Warranty law helps protect consumers by ensuring that they receive what they paid for, while also holding sellers accountable for their products, including items like electronics and vehicles.
