When Can a Defective Product Lead to a Product Liability Lawsuit?

A defective product can lead to a product liability lawsuit when a product has a problem and that problem causes an actual injury or property loss. That sounds obvious, but there’s an important difference between “I got hurt while using this product” and “this product was defective, and that defect caused my injury.” The law focuses on the second one, because that connection is the case.

A 2019 case is a good example. That summer, about 25,000 overloaded fireworks were recalled after a boy lost his left hand in an explosion involving a Talon rocket. Investigators said the recalled fireworks had excessive pyrotechnic material that could create unexpectedly powerful explosions.

That’s the kind of case that raises the questions product liability lawyers deal with all the time. What exactly was wrong with the product? Who made or supplied it?

And can the defect be tied directly to what happened?

The Four Ways a Product Can Be Legally Defective

Product defects typically fall into one of four main categories: manufacturing defects, design defects, inadequate warnings, and nonconformance with a representation.

Each one works a little differently.

1. A manufacturing defect happens when a particular product comes off the line differently from how it was supposed to be made.
2. Design defects are a broader issue. While the product may have been built exactly according to plan, the product’s design itself created an unreasonable danger.
3. A warning defect involves missing or inadequate instructions about a serious risk that users wouldn’t necessarily recognize on their own.
4. Nonconformance with a representation. The product failed to match something the manufacturer represented about it. This applies even when the manufacturer did not act fraudulently, recklessly, or negligently in making the representation.

Common examples include a pressure cooker with a faulty locking mechanism, a power tool with an unsafe design, a household chemical without proper warning labels, or even a children’s product that creates a choking or entrapment hazard.

The category matters because it changes what kind of evidence needs to be collected. A broken component may point toward manufacturing, while an entire product line with the same problem may point toward design, and missing safety instructions point toward a warning case.

Proving the Defect Caused the Injury

Proving causation means showing that the defect actually caused the injury, not simply that a defect and an injury happened around the same time.

That can become highly technical.

• An engineer may need to inspect a failed machine part.
• An automotive expert might analyze electronic data.
• A medical expert may need to explain why a medical device’s particular malfunction caused a specific injury.

Sometimes the product gets destroyed in an accident. A battery may burn up. A machine may break apart. A vehicle part may be lost on the road or during emergency repairs. That doesn’t always end the case. State laws can allow circumstantial evidence in some situations when the physical product is no longer available. Preserving the product is always better when possible.

Common Consumer Products Involved in Litigation

Almost any consumer product can become the subject of a lawsuit when a defect causes serious harm. Still, some categories come up more often than others, including cars, tires, appliances, power tools, furniture, exercise equipment, children’s products, medical devices, batteries, and industrial equipment.

Recalls matter here, too. A recall doesn’t automatically prove an individual lawsuit. It can, however, provide strong evidence that a known product problem existed. The case still needs to show that the injured person had the affected product and that the defect actually caused the injury. That’s where product identification becomes critical. Serial numbers, model numbers, packaging, and purchase records do that work.

How Statutes of Limitations Affect Your Case

Ohio gives injured people two years from the date the claim accrues to file a product liability lawsuit. Deadlines vary elsewhere, and a few states allow only one year, so waiting can create a serious problem even when the defect looks obvious.

There’s another deadline people often miss. There may be a statute of repose that generally bars claims involving products first delivered more than 10 years ago, subject to specific and narrow exceptions covering situations such as fraud about safety information, a written warranty running longer than ten years, and injuries from certain listed substances.

That can matter with older equipment. Imagine getting hurt using a machine that has been sitting in a workshop for 15 years. Your injury may be brand new, but the product’s age can still create a major legal issue. That’s why timing should be checked early. Even two years can go by quickly, and evidence can disappear much faster than that.

Steps to Take Immediately After a Product Injury

After a product injury, the priorities are your health and the product itself, preserved exactly as it was when the incident happened. Both can make or break the investigation.

1. Get medical treatment. Make sure the injury is documented clearly. Be factual and do not guess what happened when medical professionals ask you about your injury.
2. Keep the product. Don’t throw it away, don’t repair it, and don’t return it unless there’s a good reason.
3. Take photographs. Get pictures of the product, packaging, serial number, labels, and damaged components.
4. Save purchase records. Keep all related receipts, emails, warranties, instructions, and online order confirmations.
5. Check for recalls. A product recall may provide useful evidence, but don’t automatically surrender the product for a refund or replacement before the legal situation is clear.
6. Preserve witness information. Get names and contact information from anyone who saw the malfunction.
7. Save communications. Keep emails and messages from the manufacturer, retailer, insurance company, or repair business.

Once the product gets repaired or discarded, some of the best evidence may be gone.
