In practice, defective airbag matters often come down to one of these scenarios:
- No deployment when it should have during a crash that otherwise appears to meet deployment conditions.
- Unexpected deployment (for example, deployment timing that doesn’t match the collision severity).
- Overly forceful deployment tied to inflator or sensor issues.
- Repairs that changed parts after the accident—such as replaced inflators, sensors, or control modules—suggesting the system malfunctioned.
In Madison, many people initially only notice the injury and assume the airbag “did its job.” But restraint-system problems can be documented in repair notes, diagnostic reports, and the vehicle’s event data—details that become critical once insurers begin disputing causation.
