What is a Manufacturer Defect?
Everything You Need to Know

Each year, millions of products are recalled due to manufacturing defects, leading to injuries and significant damages. A manufacturing defect refers to a flaw in a product caused by poor design, substandard materials, or errors during production.

These defects can pose serious risks to consumers, and in some cases, manufacturers may even fail to address known issues.

If a defective product has harmed you or a loved one, you may have legal grounds to seek compensation. This article provides an overview of manufacturing defects, your rights as a consumer, and the steps to take in pursuing justice.

1. Design Defects

A design defect occurs when a product is inherently unsafe due to flaws in its design, making it unreasonably dangerous for its intended use. These issues affect all units of the product, as the defect originates from its conceptualization.

• Definition: The product is not reasonably safe for its intended use because of a flawed design or the absence of necessary safety features.
• Example: A car with a high center of gravity that makes it prone to rollovers during sharp turns exemplifies a design defect. This flaw affects every car produced with the same design specifications.

2. Manufacturing Defects

Manufacturing defects occur when a product deviates from its intended design due to errors during production. Unlike design defects, these issues affect only some units of the product.

• Definition: The product was not made according to the design specifications because of poor craftsmanship, sub-standard materials, or errors in the manufacturing process.
• Example: A car missing airbags due to an oversight during assembly is an example of a manufacturing defect. While the design includes airbags, some cars lack this critical safety feature.

3. Marketing Defects

Marketing defects involve inadequate warnings, misleading advertising, or a failure to provide proper instructions for safe use. These defects can lead to improper use of an otherwise safe product.

• Definition: The product becomes unsafe because consumers are not adequately warned about its risks or provided with proper usage instructions.
• Example: A chemical product sold without warnings about its potential to cause severe burns if mixed with certain substances illustrates a marketing defect.

Understanding the distinctions between these types of defects is essential for pursuing a product liability claim.

Whether the issue arises from flawed design, faulty manufacturing, or inadequate warnings, consumers have the right to seek compensation for injuries caused by unsafe products.

If you suspect a product you used is defective, consult a legal expert to determine the type of defect and the best course of action.
