Products Liability


Product liability has been referred to as strict liability. Strict liability imposes liability against a defendant for providing a product that contained a manufacturing defect, or that was defectively designed or did not include sufficient instructions or warnings of potential safety hazards. Under Negligence Law, the defendant is liable only if he or she was negligent.

The attorneys at Cheong & Denove have been helping clients injured by defective products for over 35 years.

What is Products Liability?

Thus, if a tow bar breaks because of imperfections in the steel used and the result is an injury to someone in a car following, the tow bar maker and seller must compensate those injured by the product’s failure.

Additionally, a product may be defective in design. When, because of the design, a product causes injury, the manufacturer and others who distribute the product may be responsible if (1) the product failed to perform as safely as a reasonable consumer would expect, or (2) the benefits of the design chosen by the manufacturer are outweighed by the risks inherent in the design.

For example, Ford determined to locate the gas tank of the Pinto behind the rear axle and adjacent to bolts. When it did crash testing, Ford learned that when the Pinto was struck from the rear, the gas tank would be crushed and punctured causing fires. Instead of relocating the gas tank, as Ford’s own engineers requested, which would have cost about $1.50 per car, Ford went ahead and sold the Pinto with this dangerous design. Many people unnecessarily died in car fires and many others were horribly injured. In Grimshaw v. Ford Motor Co., a case which one of our firm’s partners worked on, Ford was found liable for burn injuries.

A product may also be defective for failure to warn that a foreseeable use of the product can cause injury. For example, the antiseptic Neonyacin was distributed without warnings about use other than on a patient’s skin. The manufacturer, Upjohn, had conducted studies which showed that using Neonyacin as an antiseptic to irrigate wounds could cause destruction of the nerves in a patient’s ear and complete loss of hearing. Upjohn learned of cases of hearing loss, but ignored the danger and lied to the government, claiming there were little or no side effects from the drug. One of the firm partners represented an air traffic controller who lost his hearing and job as a result of the use of Neonyacin to irrigate a wound.
Other recent examples of defective products include Wright Medical Technology hip implant Profemur R which was found by the Los Angeles Superior Court to have defects in its manufacturing; SUVs such as the Explorer, which are prone to rollover, tires, such as Firestone Steeltex AT, which lose their tread and fail unexpectedly during operation because of their design; drugs such as Vioxx, which cause an increased risk of strokes and heart attacks; and defective and/or aggressive air bags, which put out a passenger’s eye or break necks. When products cause injury, such as in an accident caused by a defective tire, this specialized area of the law applies. This type of claim requires a lawyer who is comfortable cross-examining mechanics, engineers, pilots, biomechanical experts, and medical doctors. Success in this area is dependent on the lawyer’s knowledge of the special area of engineering involved and a knowledge of other similar claims across the¬†country.

This is incorrect. To establish liability the plaintiff needs to prove not only a product defect, but the defect was a substantial factor in causing the injury. The jury is instructed that “a substantial factor in causing harm is a factor that a reasonable person would consider to have contributed to the harm. It must be more than a remote or trivial factor. It does not have to be the only cause of the harm. Conduct is not a substantial factor in causing harm if the same harm would have occurred without that conduct.” CACI 430.

Often the manufacturer will often argue that the product was not the cause of the plaintiffs injuries. Crash tests and computer animation are often useful in demonstrating that the defect was a cause of injury.

Who Can Be Liable Under Products Liability?video still frame of skelton during air bag crash testing

Obviously, the entity that manufactures the defective product can be held liable. Once the product leaves the manufacturing plant, other entities may also be held liable. These entities include the distributor, and even the retailer who sells the product to the consumer. Even if a product is defective before it ever reaches the distributor or retailer, they can be held liable for the defect. In order for there to be liability, the injured person must prove that the defendant either manufactured, produced, distributed or sold the defective product.

Although a defense may appear on its face to be frivolous, it must be taken seriously in order to defeat it.

What Constitutes a Defect?

  • A product which was not manufactured according to specification;
  • A product which malfunctions;
  • A product which differs from the manufacturer’s intended result ;
  • A product which fails to match the quality of similar products;
  • A product design which did not perform as safely as an ordinary consumer would have expected it to perform;
  • A product that lacked sufficient instructions or failed to warn of potential risks, side effects, or allergic reactions.

  • The product was used in a way that was not reasonably foreseeable by the defendant.
  • The product was not manufactured, distributed or sold by the defendant.
  • The product performed as safely as an ordinary consumer would have expected.

  • The product’s potential risks, side effects or allergic reactions were not known or knowable through the use of scientific knowledge.
