When a product is dangerous because of an error in the manufacturing or assembly process—not its original design—you may have a manufacturing defect claim under Texas law. A manufacturing defect occurs when a product deviates from its intended design, making that specific unit unsafe even though the overall product design may be sound.

Unlike design defects that affect every product in a line, manufacturing defects typically impact individual units or batches. These cases often involve quality-control failures, improper materials, contaminated components, or mistakes during assembly that expose consumers to serious injuries.

At Moudgil Injury Law Firm, our Houston-based product liability attorneys represent individuals injured by defectively manufactured products. We investigate whether a product departed from its intended specifications and hold manufacturers accountable for preventable errors.

What Is a Manufacturing Defect Under Texas Law?

Under Texas product liability law, a manufacturing defect exists when a product does not conform to its intended design, rendering it unreasonably dangerous despite proper design and intended use.

To establish a manufacturing defect claim, an injured person generally must show that:

• The product deviated from the manufacturer’s design or specifications

• The defect existed when the product left the manufacturer’s control

• The defect caused the injury

• The product was being used in a reasonably foreseeable manner

These claims are governed by the Texas Civil Practice & Remedies Code, which outlines manufacturer liability for defective products

How Texas Courts Evaluate Manufacturing Defect Claims

Texas courts evaluate manufacturing defect claims by comparing the defective product to identical, non-defective units produced by the same manufacturer. If the injured product differs from its intended design and that difference caused harm, liability may attach.

Key Issues Courts Consider

Deviation From Design
Did the product differ from approved plans, formulas, or specifications?

Quality Control Failures
Was the defect caused by poor inspection, contamination, improper materials, or assembly errors?

Causation
Did the defect directly cause the injury?

Foreseeable Use
Was the product used in a manner the manufacturer should have anticipated?

Common Examples of Manufacturing Defects

Manufacturing defects can occur across a wide range of products.

Motor Vehicle Manufacturing Defects

• Faulty brakes or steering components

• Defective airbags or seatbelts

• Cracked frames or improperly welded parts

• Electrical failures causing fires

Many vehicle manufacturing defects are identified through recalls and investigations by the
National Highway Traffic Safety Administration.

Medical Device Manufacturing Defects

• Contaminated surgical instruments

• Improperly sterilized implants

• Weak or fractured device components

• Incorrectly assembled medical equipment

Safety alerts and adverse event reports are monitored by the
U.S. Food & Drug Administration.

Consumer Product Manufacturing Defects

• Electrical products with faulty wiring

• Children’s toys with loose or broken parts

• Appliances assembled with incorrect components

• Furniture with missing fasteners

Many dangerous consumer product defects are tracked by the
U.S. Consumer Product Safety Commission 

Pharmaceutical Manufacturing Defects

• Contaminated medications

• Incorrect dosages

• Improper labeling due to packaging errors

• Cross-contamination during production

These issues are often investigated by the FDA and may form the basis of claims involving
dangerous drugs.

Manufacturing Defects vs. Other Product Liability Claims

Manufacturing Defect vs. Design Defect
A manufacturing defect affects specific products due to errors in production.
A design defect affects every product because the design itself is unsafe.

Manufacturing Defect vs. Failure to Warn
Failure-to-warn claims focus on inadequate instructions or warnings, while manufacturing defect claims focus on physical deviations from the intended design.

Who Can Be Held Liable for a Manufacturing Defect?

Potentially responsible parties include:

• Manufacturers and assemblers

• Component suppliers

• Quality control contractors

• Distributors or sellers (in limited cases)

These claims fall under broader personal injury law principles.
