Product Liability Lawsuit Guide

A product liability lawsuit allows injured consumers to hold manufacturers, distributors, or retailers accountable for selling defective products. This guide explains the types of defects, who may be liable, and the exact steps to file a product liability claim in the United States. You’ll also learn when to hire an attorney and what compensation you may be entitled to pursue.

When you buy a product—whether it’s a household appliance, a vehicle part, a power tool, or a medical device—you expect it to be safe. But defective products injure thousands of people every year, and U.S. law allows consumers to hold manufacturers and sellers accountable when something they made or sold causes harm.

This guide gives you a clear, up-to-date explanation of how product liability lawsuits work, the types of defects that create liability, and the steps you should take if you’ve been injured by a defective product. As of 2025, courts continue to take product defect claims seriously, and many cases succeed when victims collect evidence early and work with an experienced attorney.

What Is Product Liability?

Product liability is an area of law that holds manufacturers, distributors, and retailers responsible when defective products cause injuries. These rules exist to protect consumers and ensure companies follow safe design, manufacturing, and marketing practices.

Under U.S. law, several parties in the supply chain can be found liable—even if they didn’t directly manufacture the defective component. Courts recognize that consumers often cannot pinpoint exactly where a defect occurred, so liability may extend across the chain.

Product liability claims typically arise from:

  • faulty appliances

  • defective auto parts

  • unsafe children’s products

  • dangerous electronics

  • unsafe medications or medical devices

  • harmful household tools or machinery

When a product injures you because it was defective, you may be able to file a product liability lawsuit to recover compensation for medical bills, lost wages, and pain and suffering.

Who Can Be Held Liable for a Defective Product?

A successful claim identifies which party—or multiple parties—is responsible. Liability may attach to:

Manufacturers

Manufacturers are often the primary defendants because defects frequently occur during:

  • the design phase

  • the assembly or production stage

  • the quality-control process

A manufacturer can be liable for:

  • design defects (unsafe blueprint)

  • manufacturing defects (error during production)

  • failure to warn (no adequate warnings or instructions)

Distributors and Wholesale Suppliers

If a distributor knowingly sells a dangerous product, ignores manufacturer recalls, or fails to warn retailers, they can be held liable. In some states, liability applies even if they were unaware of the defect.

Retailers

Retailers may be responsible if they:

  • sold a product with a known defect

  • ignored recalls

  • failed to remove hazardous items from shelves

Even if the retailer did nothing wrong intentionally, product liability laws may still include them in the chain of responsibility.

Types of Product Defects

There are three primary types of defects recognized in product liability law. Identifying the correct type is essential because each requires different evidence.

1. Design Defects

A design defect exists before the product is ever manufactured. The problem is baked into the blueprint, making the product inherently unsafe even when assembled correctly.

Examples include:

  • SUVs with a high rollover risk

  • power tools without adequate safety guards

  • medication with unreasonably dangerous side effects

2. Manufacturing Defects

A manufacturing defect occurs when something goes wrong during production.

Even if the design is safe, the specific unit that injured you may be dangerous because:

  • parts were assembled incorrectly

  • contaminated materials were used

  • safety components were missing

3. Marketing Defects (Failure to Warn)

Marketing defects involve inadequate warnings, missing instructions, or misleading information.

Examples:

  • failing to warn consumers that a drug interacts with other medications

  • selling a chemical cleaner without safe-use instructions

  • producing electronics that overheat without proper warnings

Elements of a Product Liability Claim

To win a product liability lawsuit, you generally must prove:

  1. The product had a defect (design, manufacturing, or marketing).

  2. The defect existed when it left the manufacturer or seller’s control.

  3. You were using the product as intended or in a reasonably foreseeable way.

  4. The defect directly caused your injury or damages.

Evidence matters. As courts become more strict, showing a clear link between the defect and your injury is essential.

Step-by-Step: How to File a Product Liability Claim

Filing a defective product claim can be overwhelming, especially if you’re dealing with medical treatment and recovery. Below is a structured, voice-search–friendly breakdown of what to do next.

Step 1: Consult a Product Liability Attorney

The first and most important step is speaking with an attorney experienced in defective product cases. They can:

  • evaluate whether your product legally qualifies as defective

  • identify all potentially liable parties

  • estimate your damages

  • protect you from insurance company tactics

  • preserve evidence before it disappears

Lawfty attorneys offer free consultations, making this step low-risk.

Step 2: Document the Incident

Write down details while they’re fresh:

  • when and where the incident happened

  • how you were using the product

  • what specifically went wrong

  • who witnessed the injury

  • what injuries you experienced

Take photos or videos of the product, the scene, and your injuries.

Step 3: Gather Evidence

Evidence strengthens your claim. Collect:

  • medical records

  • the defective product (if safe to keep)

  • user manuals and packaging

  • purchase receipts

  • surveillance footage

  • witness statements

  • recall notices

Never throw the product away—your attorney may need to send it for expert evaluation.

Step 4: Identify All Responsible Parties

A claim may include:

  • the manufacturer

  • component manufacturers

  • distributors

  • retailers

Your attorney will map the supply chain to determine exactly who contributed to the defect.

Step 5: Settlement Negotiations

Many cases resolve through settlement. Your attorney will negotiate with:

  • insurance companies

  • product manufacturers

  • defense attorneys

Good cases can settle for compensation covering medical bills, lost wages, future care, pain and suffering, and sometimes punitive damages.

Step 6: Litigation or Trial

If settlement isn’t possible, your attorney may file a lawsuit. This involves:

  • discovery

  • expert analysis

  • depositions

  • motions

  • trial before a judge or jury

Most cases settle before trial, but preparing strongly improves your bargaining power.

Why Legal Representation Matters

FAQs

Can I file a product liability claim if I wasn’t the original buyer?

Yes. In most states, you can pursue a claim even if you purchased the item secondhand or received it as a gift, as long as the defect caused your injury.

What happens if a product liability claim exceeds the manufacturer’s insurance coverage?

If damages exceed policy limits, your attorney may pursue additional responsible parties, including distributors or retailers.

How long do I have to file a defective product lawsuit?

Each state has its own statute of limitations—often 1–3 years. Speak with a lawyer quickly so you don’t miss your filing deadline.

What compensation can I recover in a product liability lawsuit?

Injured consumers may recover medical expenses, lost income, pain and suffering, property damage, and in some cases, punitive damages.

How do I know if my product qualifies as “defective”?

A product is defective if it has a design flaw, manufacturing error, or missing/insufficient warning that makes it unsafe when used normally.

Do I have to prove the company was negligent?

Not always. Many states allow strict liability, meaning you can win your case even if the manufacturer wasn’t negligent—as long as a defect caused your injury.
