Product Liability Lawsuit Process: Suing for Defective Product Injuries in 2025

## What Is a Product Liability Lawsuit?

A product liability lawsuit holds manufacturers, distributors, and retailers legally responsible for injuries caused by defective or unreasonably dangerous products. Unlike standard negligence claims, product liability often does not require proving the manufacturer was careless — under strict liability theory, you only need to prove the product was defective and that the defect caused your injury. Products that cause injury liability claims include defective vehicles, dangerous medications, malfunctioning medical devices, contaminated food, defective children's toys, and unsafe consumer electronics.

Product liability cases frequently involve class actions when a defect affects thousands of consumers — joining or leading a class action can produce larger recoveries than individual lawsuits for lower-value individual claims.

The Three Legal Theories in Product Liability Cases

Your attorney may pursue one or more theories depending on the nature of the product defect and your injuries.

• **Design defect:** The product's overall design is inherently unsafe even when manufactured correctly — an example is a car with a fuel tank positioned where it is prone to explosion in rear-end collisions
• **Manufacturing defect:** The product's design is safe, but a specific unit was made incorrectly during production — a batch of pills with the wrong dosage or a car with a faulty brake component
• **Failure to warn (marketing defect):** The product is potentially dangerous but lacks adequate warnings or instructions that would allow consumers to use it safely — applies commonly to medications with known side effects and power tools with hidden hazards
• **Preserving the product:** In product liability cases, preserving the defective product is critically important — never throw away or repair a product you believe caused your injury; it is your most important piece of evidence
• **Multiple defendants:** The entire chain of distribution — manufacturer, parts supplier, assembler, distributor, and retailer — may all bear liability, and your attorney will name all potentially responsible parties to maximize recovery

Product liability cases often require significant upfront investment in engineering experts and product testing — retain an attorney with specific product liability experience and resources.
