What must a plaintiff prove in an express warranty case?

In an express warranty case, the primary requirement for the plaintiff is to demonstrate that the product did not conform to the seller's explicit representations about it. An express warranty is a specific assurance made by the seller, often conveyed through statements or descriptions regarding the quality, condition, or performance of the product. If the product fails to meet these stated promises, the plaintiff has grounds to claim a breach of warranty.

This requirement does not necessitate that the product be completely free of defects or that it caused injury or environmental damage. The focus is solely on whether the product lived up to what the seller represented it to be. Thus, the plaintiff's burden is to show that the product's performance or characteristics did not align with the seller's assertions, leading to an actionable claim under the express warranty.
