How to Prove a Product Was 'Unreasonably Dangerous' Under the Tennessee Product Liability Act

When you purchase a product-whether it is a household appliance, a power tool, or a children's toy-you rightfully expect it to be safe when used as intended. Unfortunately, thousands of people are severely injured every year by products that have hidden flaws. If you are injured by a defective product in Tennessee, the law provides a pathway for you to seek financial compensation from the company that designed, manufactured, or sold it. This process is governed almost entirely by the Tennessee Product Liability Act (TPLA), a specific set of statutes that dictate exactly how these claims must be handled.

However, simply getting hurt while using a product does not automatically mean the manufacturer is legally responsible. To win a product liability lawsuit in Tennessee, you must successfully prove that the product was 'unreasonably dangerous' or 'defective' at the exact moment it left the manufacturer's control. Proving this requires navigating complex legal standards, relying on engineering experts, and understanding specific judicial tests. This guide explains the core of the TPLA, the different ways a product can be flawed, and the evidence you need to build a strong case.

Understanding the Tennessee Product Liability Act (TPLA)

The Tennessee Product Liability Act, codified at Tenn. Code Ann. § 29-28-101 and subsequent sections, governs all lawsuits brought against manufacturers and sellers for product-related injuries. Under this law, you cannot simply say 'the product hurt me.' You must prove the product was defective or unreasonably dangerous. Tennessee courts rely heavily on two distinct legal tests to make this determination, established by landmark cases such as Ray v. BIC Corp., 925 S.W.2d 527 (TN Supreme Court 1996). Your attorney will determine which test best fits the facts of your injury.

The Consumer Expectation Test

The 'consumer expectation test' asks a simple question: Was the product more dangerous than an ordinary consumer would reasonably expect when using it in a normal way? For example, if you buy a coffee maker and it suddenly catches fire while brewing, it clearly fails the consumer expectation test. An ordinary person expects a coffee maker to brew coffee, not to spontaneously combust. This test is generally used for straightforward products where the everyday user understands how it is supposed to function.

The Prudent Manufacturer Test

For highly complex products-like pharmaceuticals, medical devices, or intricate car engine components-the average consumer does not have the technical knowledge to know exactly what to expect. In these cases, courts apply the 'prudent manufacturer test.' This test asks: If the manufacturer knew about the danger, would a reasonably careful manufacturer have still put the product on the market? Winning under this test requires bringing in industry experts to testify that the manufacturer ignored safety protocols or chose profits over consumer safety.

Step-by-Step Process in Tennessee

Filing a product liability lawsuit involves strict court procedures. Whether your injury occurred in Memphis, Nashville, or Knoxville, here is how the legal process generally unfolds.

Step 1: Seek Medical Care and Preserve the Product

Your health is your first priority. Seek immediate medical attention and ensure the doctor documents that your injuries were caused by the product. Most importantly, do not throw the product away, return it to the store, or attempt to fix it. Keep the product exactly as it is, along with the packaging and your receipt.

Step 2: Consult an Attorney and Inspect the Evidence

A specialized attorney will take possession of the product and hire independent engineers or safety experts to inspect it. They will determine if the flaw was a design defect, a manufacturing error, or a failure to warn.

Step 3: Filing the Civil Lawsuit

Your lawyer will draft a formal complaint pursuant to Tenn. R. Civ. P. 3 and file it in the appropriate state court, such as the Davidson County Circuit Court, Nashville or the Shelby County Circuit Court, Memphis, after which the court clerk issues a Civil Summons governed by Tenn. R. Civ. P. 4. The initial filing fee is generally between $250 and $300.

Step 4: The Discovery Phase

Once the lawsuit is filed, both sides enter 'discovery.' Your legal team will demand internal emails, safety testing records, and design blueprints from the manufacturer. This is where your attorney uncovers whether the company knew about the defect and tried to hide it.

Step 5: Trial or Settlement

Product liability cases are incredibly expensive for manufacturers to fight. Often, if your evidence is overwhelming, they will offer a settlement. If they refuse to offer fair compensation for your medical bills and pain, your attorney will present your case to a local jury.

Types of Defects: Design, Manufacturing, and Warnings

Under the TPLA, there are three primary ways to classify an unreasonably dangerous product. Identifying the correct category is essential for your lawsuit.

Design Defects

A design defect means the product was manufactured perfectly, but the original blueprint itself was inherently dangerous. For example, an SUV designed with a center of gravity so high that it easily rolls over taking a normal turn has a design defect. To win this type of claim, your lawyer must often prove that a safer, cost-effective alternative design was available but ignored by the company.

Manufacturing Errors

A manufacturing error occurs when the design is safe, but something went wrong on the assembly line. Perhaps a batch of bicycles was assembled with the wrong type of screws, or a bottle of over-the-counter medicine was contaminated at the factory. In these cases, only a specific batch or a single item is dangerous, and you must prove the defect happened before it left the factory.

Failure to Warn

Some products are naturally dangerous but still useful (like chainsaws or powerful prescription drugs). In these instances, the manufacturer has a strict legal duty to provide adequate warnings and clear instructions. If a dangerous side effect or risk is not clearly labeled, the product is considered legally defective due to a 'failure to warn.'

Burden of Proof and Immediate Evidence Needs

In a civil lawsuit, the 'burden of proof' rests entirely on you, the plaintiff. You must prove by a preponderance of the evidence that the defect directly caused your injury. Gathering evidence quickly is crucial. Beyond saving the physical product itself, you should try to secure the original packaging, user manuals, and any witness statements. If the product was part of a broader recall issued by a federal agency, your attorney will use that recall notice as powerful evidence that the manufacturer recognized the danger.

How Much Does it Cost in Tennessee?

Product liability cases are highly complex and expensive to litigate, but the financial structure protects the injured victim:

• Contingency Fees: Most Tennessee product liability attorneys work on a contingency fee basis. This means you pay zero upfront costs. The lawyer only gets paid (usually 33% to 40%) if they win your case.
• Court Filing Fees: The baseline fee to open a civil lawsuit in a Tennessee Circuit Court is roughly $250 to $300.
• Expert Witness Costs: Winning often requires hiring costly engineers, medical professionals, or accident reconstructionists. These experts can cost $10,000 to $50,000, but reputable law firms will advance these costs for you and recover them from the final settlement.

How Long Does the Process Take?

Because these cases often involve massive national or international corporations, they take time. A relatively straightforward manufacturing defect case might settle in 12 to 18 months. However, complex design defect cases-especially those involving pharmaceuticals or auto manufacturers-can involve years of intense discovery and pre-trial motions. Expect heavy litigation to take anywhere from 2 to 4 years to reach a jury trial.
