Consumers in the U.S. are protected by a number of provisions of both state and federal laws with regard to promises or “warranties” made by companies about their products.
Some of these warranties are in written or spoken form. These are called “express warranties.” However, there are also certain unwritten, unspoken expectations to which consumers are entitled. These are called “implied warranties.”
Essentially, consumers almost always have some recourse when products don’t meet their basic expectations – especially when the result is someone is injured. The most common that we see in product liability law is implied warranty of merchantability. That means the product is guaranteed to work and be reasonably safe when used for its intended purpose.
