Definition - What does Express Warranty mean?
An express warranty is a manufacturer's statement that its product will retain a certain quality for a certain duration of time and its promise to fix the product if damages occur to it during that time. The damages must be specifically covered in the warranty. For example, an express warranty on a computer may cover hardware malfunctions but not damage from the computer being dropped.
Justipedia explains Express Warranty
Essentially, an express warranty is hedge that sellers or manufacturers offer to buyers as protection against certain types of product damage. The goal is to give buyers more confidence that they are making a good purchase when they buy the product. Sometimes warranties come automatically with the product upon purchase. Sometimes they are optional in purchase agreements. For example, a golf cart seller may offer a three year warranty for a certain amount of money. The buyer can choose to opt in or out of that part of the sale.
