Product Liability Claims: How to Sue When a Defective Product Injures You

The Consumer Product Safety Commission reports approximately 12.4 million product-related injuries annually that require emergency room treatment. From defective airbags (Takata, 67 million vehicles recalled) to dangerous medications (Vioxx, linked to 27,000 heart attacks) and faulty appliances, product liability law holds manufacturers, distributors, and retailers accountable when their products cause harm. One of the most powerful aspects of product liability law is the doctrine of strict liability, you don't need to prove the manufacturer was negligent, only that the product was defective and caused your injury.

Three Types of Product Defects

• Manufacturing Defect

  The product design was sound but something went wrong during production, a car brake pad that wasn't assembled correctly, a drug with incorrect dosage due to manufacturing error. Only some units are affected. Proving a manufacturing defect requires showing the specific unit deviated from the intended design.

• Design Defect

  Every unit of the product is inherently dangerous because of how it was designed. The Ford Pinto's fuel tank placement and the original Jeep CJ's rollover tendency are classic examples. Plaintiffs must show either a consumer expectation test (the product performed more dangerously than an ordinary consumer would expect) or a risk-utility test (risks outweigh benefits).

• Failure to Warn (Marketing Defect)

  The product was properly made and designed but lacked adequate warnings or instructions about known risks. Pharmaceutical companies are especially vulnerable, failure to adequately warn about drug side effects is the basis for thousands of mass tort litigations annually. The warning must be prominent, specific, and understandable.

Preserve the product and all packaging in its post-incident state, do not repair it, return it to the store, or throw it away. The defective product itself is the most important evidence in your case. Photograph your injuries and the product from multiple angles. Seek medical attention and follow through with all recommended treatment. Report the incident to the CPSC at SaferProducts.gov. Search for recalls on the CPSC website and NHTSA database (for vehicle components), existing recalls dramatically strengthen your case and may make you eligible for a class action lawsuit.

Class action product liability lawsuits allow multiple injured parties to combine their claims against a manufacturer, making litigation economically viable even for smaller individual damages. Mass tort cases, where plaintiffs file individually but cases are coordinated by a judge in multidistrict litigation (MDL), are common for pharmaceutical injuries. In class actions, individual plaintiffs typically receive smaller shares of a large settlement fund. In mass torts, each plaintiff's individual damages are assessed separately, making total recovery significantly higher for those with serious injuries. Consult a product liability attorney to determine which litigation structure best serves your situation.

Product liability claims are based on three distinct types of defects, each requiring different evidence and legal analysis. Design defects exist when a product's fundamental design is inherently dangerous even when manufactured correctly; examples include vehicles with a high rollover risk due to their center of gravity or children's toys with small parts that pose choking hazards. Manufacturing defects occur when a specific product deviates from its intended design during production, such as a batch of tires made with defective rubber that causes blowouts or a medication contaminated during the manufacturing process. Marketing defects involve inadequate warnings, instructions, or labeling that fail to inform consumers about known risks; examples include medications that do not warn about dangerous side effects or power tools that lack proper safety instructions. In many states, product liability operates under strict liability, meaning you do not need to prove the manufacturer was negligent; you only need to show that the product was defective and that the defect caused your injury.

Product liability extends to every entity in the chain of distribution, providing injured consumers with multiple potential sources of recovery. The product manufacturer bears primary liability for design and manufacturing defects, and large manufacturers typically carry substantial insurance policies and assets to satisfy judgments. Component manufacturers can be held liable when a specific part they produced caused the defect, even if the finished product was assembled by a different company. Distributors and wholesalers can be liable even though they did not design or manufacture the product, because they are part of the commercial chain that brought the defective product to market. Retailers including brick-and-mortar stores and online marketplaces may be liable for selling defective products, particularly when they had reason to know about the defect or failed to pass along safety warnings. In cases involving products from foreign manufacturers who may be difficult to pursue legally in the United States, the domestic distributor and retailer become especially important defendants because they provide an accessible path to recovery for injured consumers.

The actions you take immediately after being injured by a defective product can make or break your claim. Preserve the defective product exactly as it was at the time of the incident; do not repair, modify, discard, or return it, because the product itself is the most critical piece of evidence in your case. Photograph the product, the injury, and the scene from multiple angles before anything is moved or changed. Seek medical attention promptly and inform your healthcare provider that your injury was caused by a product, as this creates a medical record linking your injury to the defect. Keep all packaging, instructions, warnings, receipts, and warranty information associated with the product. Report the incident to the Consumer Product Safety Commission (CPSC) through their online portal at SaferProducts.gov, which creates an official record and may trigger a broader investigation or recall. Contact a product liability attorney quickly because evidence can be lost, witnesses' memories fade, and statutes of limitations apply; most product liability attorneys offer free consultations and work on contingency fees, so there is no financial risk in getting a professional evaluation of your claim.
