Utah Strict liability is a legal doctrine that makes a product manufacturer liable for damages caused by a defective product, even if the manufacturer was not negligent in designing, making, or selling the product. In order for a plaintiff to succeed in a strict liability claim, they must prove that the product was defective in design, and that the defect was the cause of the injury. The three types of design defects in Utah are manufacturing defects, design defects, and failure to warn. A manufacturing defect is a problem with the way a product is made, while a design defect is a problem with the product’s design, and a failure to warn is when a product does not provide adequate warning of potential dangers.
