When a Vehicle Defect Makes a Crash Worse

A crashworthiness claim holds a vehicle manufacturer accountable when a defect worsens your injuries during a crash. Common defects include airbags that fail to deploy, roofs that crush inward, seatbelts that don’t lock, or fuel tanks that rupture.

Unlike a typical accident claim—which focuses on who caused the crash—a crashworthiness case targets the vehicle itself: its design, safety systems, and how well it protects you.

Here’s what many injured people don’t know: you can have a valid crashworthiness claim even if you caused the collision. The manufacturer’s duty to protect you is separate from the question of who caused the accident.

In the catastrophic-injury cases we handle, we regularly see crashes that should have been survivable become life-altering. A rollover that crushes the roof, leaving someone with a spinal cord injury and permanent paralysis. An airbag system that fails to deploy in a moderate-speed crash, resulting in traumatic brain injury. A fuel-system rupture that ignites after the crash, causing severe burns. These aren’t random misfortunes—they’re often the result of a manufacturer’s failure to design and build a vehicle that protects occupants.

What Does Crashworthiness Mean?

Crashworthiness is a vehicle’s ability to protect occupants during and after a collision. It includes the vehicle’s design, safety features, and structural strength. This is different from crash causation—the question of who caused the accident itself.

Think of it as two separate legal events:

First, the crash happens. You may have run a red light. Another driver may have hit you. Weather may have caused you to lose control. You may be 100% responsible for that collision.

Second, the vehicle either protects you or fails you. If the airbag deploys, the seatbelt locks, the roof stays intact, and the fuel system doesn’t rupture, the vehicle has done its job. If any of those systems fail, the manufacturer may be liable for the injuries that result.

This distinction is enormous. Many injured people believe that if they caused the crash, they have no legal claim. Under Florida’s comparative-negligence rule (Fla. Stat. § 768.81), your fault for causing the collision does not eliminate your right to recover for injuries caused by the vehicle’s defects. You can recover full damages for injuries caused by a defect, even if you were at fault for the crash itself.

How Vehicle Defects Turn Survivable Crashes Into Catastrophic Injuries

The concept of the “second collision” captures this reality. The first collision is the impact itself. The second collision is what happens inside the vehicle: your body strikes the steering wheel, dashboard, or side panel.

A well-designed vehicle absorbs crash energy and protects occupants. A defective vehicle fails to protect you, and your injuries become catastrophic.

Common vehicle defects that amplify injury severity:

• Airbag non-deployment or malfunction: An airbag that fails to inflate, deploys too late, ruptures, or deploys with insufficient force leaves occupants unprotected. In moderate-speed frontal collisions, a non-deploying airbag can result in facial trauma, head injury, or spinal trauma.

• Seatbelt failures: Seatbelts that don’t lock during a crash fail to restrain the body. A lap belt that rides up over the abdomen instead of staying on the pelvis can cause internal injuries and spinal trauma.

• Roof crush in rollovers: Insufficient structural rigidity causes the roof to collapse inward, crushing occupants. Roof crush frequently results in spinal cord injury, paralysis, or death.

• Seat-back collapse: Rear-impact crashes can cause front-seat backs to collapse backward, injuring rear-seat occupants and causing spinal injuries.

• Fuel-system rupture: Fuel tanks that rupture or leak during a crash can ignite, causing post-crash fires and severe burns to occupants trapped in a burning vehicle.

• Door-latch failures: Doors that open during or after a crash can eject occupants or allow them to fall from the vehicle, resulting in catastrophic injury or death.

• Frame and structural defects: Inadequate crumple zones or structural support fail to absorb crash energy, transferring force directly to occupants instead of dissipating it.

Each of these defects can transform a survivable collision into a life-altering catastrophe. Spinal cord injuries and paralysis result from roof crush or seat-back collapse. Traumatic brain injuries arise from inadequate head protection. Amputations can result from door-latch failures or entrapment. Severe burns follow fuel-system ruptures. In the most devastating cases, these defects result in wrongful death.

The Legal Duty: What Manufacturers Owe You

Vehicle manufacturers, designers, and component suppliers have a legal duty to design and build vehicles that protect occupants in foreseeable crashes. This duty exists independently of who caused the collision. Manufacturers must anticipate that crashes will happen and design vehicles to minimize resulting injuries.

This duty applies to crashes of all severities—high-speed head-on collisions, moderate-speed side impacts, even low-speed rear-end crashes. A defect that fails to protect occupants in any foreseeable crash scenario can create liability.

Defects can exist in three forms:

1. Design defects: The vehicle’s design itself is unsafe. For example, a roof structure that is too weak to withstand rollover forces, or an airbag system that deploys too slowly.

2. Manufacturing defects: The design is sound, but the vehicle was built incorrectly. For example, a seatbelt anchor installed improperly, or a defective airbag sensor.

3. Failure to warn: The manufacturer knew of a hazard but failed to warn occupants or provide adequate instructions for safe use.

Dealers and distributors can also bear liability in certain circumstances—for example, if they knew of a defect and failed to perform a required repair or recall.

Crashworthiness Claims Even If You Caused the Crash

This principle transforms lives. Under Florida’s comparative-negligence statute (Fla. Stat. § 768.81), an injured person can recover damages even if they were partially at fault for the collision—as long as they were not more than 50% at fault. More importantly, your percentage of fault for causing the crash does not reduce your recovery for injuries caused by the vehicle’s defects.

Here’s a concrete example:

You’re speeding and run a red light, causing a collision. The crash is your fault. But your vehicle’s airbag fails to deploy. As a result, you suffer a traumatic brain injury that leaves you with permanent cognitive impairment. You were 100% at fault for causing the crash, but the manufacturer is 100% liable for the defect that worsened your injury. You can recover full damages for the injury caused by the airbag failure, even though you caused the collision.

This distinction is crucial. Many injured people don’t pursue crashworthiness claims because they believe their role in causing the crash disqualifies them. It doesn’t. If you believe a vehicle defect made your injuries worse, you may have a valid claim regardless of who caused the accident.

Proving a Vehicle Defect: The Role of Expert Witnesses

Proving a crashworthiness case requires expert engineering analysis. This is where the complexity of these cases becomes apparent. You cannot rely on eyewitness testimony or photographs alone. Forensic engineers, biomechanical specialists, and accident reconstructionists must examine the vehicle, the crash dynamics, the design standards applicable to that vehicle, and how other manufacturers addressed the same safety challenge.

The proof process typically involves:

• Forensic engineering examination: A qualified mechanical engineer inspects the vehicle, documents the defect, and analyzes whether the design or manufacturing was deficient. This expert examines structural integrity, weld quality, material specifications, and whether the component met applicable industry standards.

• Biomechanical analysis: A biomechanical specialist analyzes how crash forces were transmitted to your body and how the defect caused or worsened your specific injury. This expert links the vehicle’s failure to your catastrophic outcome.

• Crash reconstruction: A crash-reconstruction expert analyzes the impact forces, the vehicle’s response, and how the defect contributed to your injury. This expert uses physics, vehicle dynamics, and accident-investigation data to establish what happened during the collision.

• Comparison to industry standards: What did competing manufacturers do? If other vehicles in the same class had better protection, that strengthens your case. Industry standards, federal motor vehicle safety standards (FMVSS), and engineering best practices all inform this analysis.

• NHTSA crash-test data and safety ratings: The National Highway Traffic Safety Administration publishes crash-test results and safety ratings. These data show how vehicles perform in standardized crash scenarios and provide objective benchmarks for design adequacy. NHTSA’s New Car Assessment Program (NCAP) tests vehicles in frontal, side, and rollover scenarios.

• Vehicle recalls and technical service bulletins: If the manufacturer later issued a recall for the same defect, that’s powerful evidence that the defect existed and that the manufacturer knew about it. Technical service bulletins (TSBs) issued to dealers can also reveal known defects.

• Medical causation: A medical expert links the defect to your specific catastrophic injury, explaining how the defect caused or worsened your condition.

This multi-disciplinary approach requires years of investigation and expert coordination. Crashworthiness cases are among the most complex product-liability claims. Expect your attorney to work with multiple specialists, each bringing distinct experience to establish both the defect and its role in your injury.

Vehicle Recalls and NHTSA Data

A vehicle recall occurs when the manufacturer or the National Highway Traffic Safety Administration (NHTSA) identifies a safety defect affecting multiple vehicles. The manufacturer must notify owners and typically offer a free repair.

Recalls strengthen crashworthiness claims but are not required to prove liability. If your crash occurred before a recall was issued for the defect that injured you, you still have a claim. The fact that the manufacturer later acknowledged the defect and issued a recall is evidence that the defect existed at the time of your crash.

If no recall has been issued, that doesn’t eliminate your claim. The absence of a recall may mean the defect hasn’t been widely recognized or reported—or it may mean the manufacturer is aware of the defect but hasn’t yet issued a recall.

NHTSA maintains a public database of vehicle complaints, defect investigations, and recalls at safercar.gov. This data can be invaluable in proving that your vehicle’s defect is part of a pattern affecting multiple vehicles.

Who Is Liable in a Crashworthiness Case?

Multiple parties can bear liability:

• The vehicle manufacturer: The company that designed and assembled the vehicle is typically the primary defendant.

• Component suppliers: Companies that manufactured specific defective parts—an airbag supplier, a seatbelt manufacturer, a fuel-tank supplier—can be held liable for defects in their components.

• Dealers and distributors: In some circumstances, if they knew of a defect or failed to perform a required repair or recall, they may share liability.

In complex cases, multiple defendants may share liability. For example, a roof-crush case might name the vehicle manufacturer, the steel supplier, and the roof-panel manufacturer.

Preserving Vehicle Evidence After a Crash

The vehicle itself is the primary evidence in a crashworthiness case. Do not allow the vehicle to be scrapped, crushed, or repaired without first documenting the defect and consulting an attorney.

Immediately after a crash:

1. Photograph the vehicle from multiple angles, focusing on any visible damage, defects, or failed safety systems.

2. Document the vehicle’s condition: Note the position of airbags, seatbelts, doors, and any signs of structural failure.

3. Preserve the vehicle: Do not authorize repairs, scrapping, or crushing. Notify your insurance company and the other party’s insurance that you are preserving the vehicle as evidence.

4. Contact an attorney: As soon as possible, notify an attorney experienced in crashworthiness cases. They can issue a preservation notice (a legal hold) to prevent the vehicle from being destroyed.

Once the vehicle is scrapped or crushed, critical evidence is lost forever. Forensic engineers need to examine the vehicle’s structure, safety systems, and the specific way it failed during the crash. Without the vehicle, proving the defect becomes exponentially more difficult.

Statute of Limitations: Time Limits for Filing

In Florida, the statute of limitations for product-liability claims is generally 4 years from the date of injury to file a lawsuit, per Fla. Stat. § 95.11.

For wrongful-death claims, the deadline is 2 years from the date of death, per Fla. Stat. § 95.11(4)(d).

In some cases, the “discovery rule” may extend the deadline. If you didn’t discover the defect until after the crash—for example, if a hidden manufacturing defect only became apparent during repair—the clock may start when you discovered the defect, not when the crash occurred.

If your crash occurred in another state, different statutes of limitations may apply. Nationwide cases require careful attention to each jurisdiction’s deadlines. Don’t delay: contact an attorney as soon as possible to ensure your claim is timely filed.

Wrongful-Death Crashworthiness Claims

When a vehicle defect results in death, the surviving family members may bring a wrongful-death claim. This is the most catastrophic outcome—a death that might have been prevented or delayed if the vehicle had been properly designed and built.

Wrongful-death damages typically include:

• Loss of life: The value of the deceased’s life and lost years.

• Loss of companionship and consortium: The emotional loss suffered by surviving spouse, children, and parents.

• Funeral and medical expenses: Costs incurred before death.

• Loss of financial support: Income the deceased would have earned.

According to the National Highway Traffic Safety Administration (NHTSA), vehicle defects contribute to a significant portion of fatal crashes. In 2022, NHTSA data showed that over 42,000 traffic fatalities occurred in the United States. When a defect prevents a vehicle from protecting occupants in a survivable crash, it can mean the difference between life and death. If you lost a family member in a crash and believe a vehicle defect played a role, a wrongful-death claim may be available to your family.

How a Crashworthiness Case Begins

The process typically unfolds as follows:

1. Initial consultation: You meet with an attorney and describe the crash, your injuries, and the vehicle.

2. Investigation: The attorney gathers crash reports, medical records, vehicle information, and photographs. The vehicle is preserved.

3. Expert retention: Forensic engineers, biomechanical specialists, crash-reconstruction experts, and medical specialists are hired to analyze the defect and your injuries.

4. Demand and negotiation: The attorney presents evidence to the manufacturer’s insurance and legal team, demanding compensation.

5. Litigation: If settlement is not reached, the attorney files a lawsuit and pursues the case through discovery, expert reports, depositions, and potentially trial.

Crashworthiness cases are complex and typically take 2 to 5 years or longer from crash to settlement or verdict. The process requires extensive expert analysis, document review, and often depositions of engineers and company representatives.

Why Crashworthiness Cases Are Different

Crashworthiness cases differ from typical personal injury lawsuits in several important ways:

• Product liability, not negligence: The focus is on the vehicle’s design and safety, not the driver’s conduct.

• Complex causation: Requires expert testimony on engineering, crash dynamics, biomechanics, and medical causation—not just eyewitness accounts.

• High-value claims: Catastrophic injuries and wrongful death often result in substantial damages.

• Manufacturer resources: Defendants are large corporations with extensive legal and technical resources, sophisticated defense strategies, and access to their own experts.

• Long timeline: Investigation, expert analysis, and litigation take years, requiring patience and commitment from the injured person and their family.
