Product Liability and Automotive Defects

Under product liability law, vehicle manufacturers may be held strictly liable for injuries caused by unreasonably dangerous components, even when they complied with federal safety standards. This includes design defects, manufacturing defects, and failure to warn. Plaintiffs are not required to prove negligence—only that the vehicle or part was defective, the defect caused injury, and the vehicle was being used as intended.

Restraint System Failures: Airbags and Seatbelts

Modern vehicles rely on airbags and seatbelts to reduce injury during a crash. When these systems fail, the consequences can be severe. Victims commonly ask, “Can I sue if my seatbelt failed during a crash?”. These lawsuits investigate inertial unlatching, pretensioner failure, webbing tears, or buckle defects.

In parallel, Defective Airbag Lawyers and Defective Airbag Attorneys handle claims involving non-deployment, delayed deployment, or airbag explosions caused by defective inflators. These failures can be traced to faulty sensors, outdated deployment algorithms, or degraded components. In both seatbelt and airbag claims, forensic engineers and biomechanical experts are essential to proving causation and fault.

Crashworthiness and Structural Failure

The concept of “crashworthiness” focuses on how well a vehicle protects occupants in an otherwise unavoidable accident. Under this doctrine, manufacturers may be held responsible when a defect worsens injuries beyond what would have occurred in a properly designed vehicle.

Common claims include injured by a roof collapse in a rollover, roof crushed during rollover, and seatback collapsed during rear-end collision. In these cases, vehicle integrity is critical. A Vehicle Rollover Attorney often evaluates roof strength, seatback rigidity, and seat anchor reliability. These defects typically involve second-collision injuries, where the harm results not from the crash itself but from the vehicle’s failure to protect the occupant during the crash sequence.

Brake and Steering System Defects

Failures in fundamental control systems—such as brakes and steering—frequently lead to catastrophic accidents. Questions like “Was my accident caused by a brake system failure?” arise when vehicles do not respond as expected. Common problems include master cylinder leaks, brake booster defects, or ABS malfunction. These failures can be rooted in both mechanical and electronic components.

Similarly, steering system defect claims often center on loss of control caused by power assist failures, rack-and-pinion separation, or electronic steering software glitches. In newer vehicles, where automation is increasingly common, liability may extend to the software architecture or calibration protocols used by manufacturers or their subcontractors.

Legal Recovery and the Path Forward

Product defect litigation is often complex and technical—but it plays a vital role in consumer protection. Whether involving airbags, restraint systems, or roof structure integrity, these claims can force corporate accountability and drive meaningful design reform. Attorneys working on a personal injury case must preserve the vehicle, gather component-level evidence, and retain credible expert witnesses.

For victims, these cases are about more than compensation. They expose preventable safety failures and compel industry change. When defects like seatbelt failure, airbag non-deployment, or rollover roof collapse cause serious harm, litigation becomes a necessary tool to address both individual justice and public safety.
