An airbag can deploy, fail to deploy, rupture, or be replaced without that fact alone proving a defect or showing which injuries the restraint system caused or failed to prevent.

The analysis should separate two events: what caused the vehicle collision and what happened to the occupant during the collision. The second question can involve seat position, belt use and geometry, crash direction and severity, airbag system status, deployment timing, occupant movement, contact, and medical mechanism.

Identify the vehicle, occupant, and restraint system

  • Vehicle identification number, year, make, model, trim, build date, ownership, purchase, title, registration, mileage, crash history, repair history, and vehicle-history sources
  • Seating position, seat track, seatback, head restraint, occupant size, posture, belt routing, buckle, pretensioner, load limiter, child restraint, clothing, carried objects, and pre-impact movement
  • Airbag type and location, module, inflator, sensor, occupant-classification system, warning lamp, diagnostic code, replacement part, manufacturer, supplier, label, serial, and date code
  • Impact direction, overlap, speed change, crash pulse, intrusion, rotation, rollover, secondary impacts, final rest, rescue, and post-crash handling
  • Exact alleged event: unwanted deployment, nondeployment, late deployment, rupture, fragment release, fire, counterfeit or substandard replacement, or another condition

Airbags are supplemental and do not deploy in every crash

The National Highway Traffic Safety Administration’s airbag guidance explains that airbags supplement seat belts and that deployment depends on crash characteristics, vehicle-system strategy, sensor location, and occupant classification. A nondeployment is not automatically a malfunction, and a deployment can cause injury without automatically proving defective design or manufacture.

Preserve the owner’s manual and the correct technical information for the subject model rather than relying on a generic deployment threshold. Do not power, probe, open, remove, replace, discard, or destructively test an airbag component or control module merely to see what it does.

Check recalls and replacement history by VIN and component

NHTSA maintains a current Takata recall resource describing affected inflators, risk groups, urgent warnings, and VIN-based recall checks. The existence of a large recall does not establish that a particular vehicle contained the recalled component on the collision date or that the component caused the claimed injury.

  • Save the dated VIN lookup, recall number, manufacturer notice, remedy status, dealer communication, appointment, repair order, part number, and completion record
  • Identify whether the original airbag deployed in an earlier collision and what replacement module or inflator was installed
  • Preserve invoices, salvage or auction history, photographs, scan reports, technician notes, parts source, packaging, labels, shipping, and removed components
  • Distinguish a safety recall, service campaign, technical bulletin, consumer complaint, defect investigation, and final agency finding
  • Recheck the vehicle and component identification if records conflict or the dashboard, seat, steering wheel, or trim was replaced

Warren separates crash cause from enhanced injury

In the opinion reported in Warren v. Colombo, the North Carolina Court of Appeals recognized that a complaint could state a negligence theory alleging a vehicle-design condition enhanced injuries even though that condition did not cause the collision. The decision addressed pleading sufficiency; it did not establish that every claimed secondary injury is attributable to a product condition.

An enhanced-injury analysis compares the occupant outcome in the actual crash with the injury-producing effect attributed to the alleged condition. That requires reliable crash, restraint, product, and medical evidence rather than an assumption that all injury after deployment came from the airbag.

A design theory must satisfy Chapter 99B

G.S. 99B-6 requires proof that the manufacturer acted unreasonably in design or formulation, that the conduct proximately caused the claimed harm, and one of the statutory alternatives concerning a safer practical feasible design or an otherwise unreasonable design. The section also lists factors for evaluating reasonableness.

A warning, manufacturing deviation, replacement-part, seller, installer, maintenance, alteration, warranty, recall, and design theory should not be merged. Identify the defendant, product role, conduct, governing section, evidence, causal mechanism, and defense for each.

Preserve the physical, electronic, and medical record

  • Full vehicle and interior photographs, measurements, three-dimensional data, restraint components, airbag modules and curtains, sensors, seats, trim, glass, occupant contacts, clothing, and biological or fragment evidence
  • Event-data recorder and restraint-control-module information collected with the method, tool and software version, raw file, report, limitations, and chain of custody
  • Diagnostic scans before repair or battery disconnection, warning-lamp history, codes, freeze-frame information, module configuration, calibration, software, and post-event changes
  • Emergency, hospital, imaging, procedure, photograph, pathology, retained-fragment, prior-condition, later-condition, and provider-causation records linked to the claimed contact and timing
  • A joint inspection and testing protocol addressing notice, participants, sequence, non-destructive work, destructive work, samples, video, measurements, custody, storage, and disposition
