Various conditions can result in a defective airbag. Individuals are likely more familiar with the Takata airbag recalls that have gone on for quite some time. This issue was driven by long-term exposure to high heat and humidity that causes the airbags to explode when deployed. This was a pure manufacturing defect that has affected billions of dollars worth of merchandise, led to significant injuries, and even caused death.
Generally, some of the main issues that can lead to defective airbags include:
Depleted airbag backup battery. If the battery of the vehicle dies, then the backup battery that powers the airbags may also die. This can fix itself after the battery is fully charged once more.
Damaged airbag clock spring. There is an airbag clock spring that maintains continuity between the airbag and the electrical wiring of the vehicle. This clock sprain coils in and out as you turn the steering wheel and can deteriorate over time, leading to a weak connection and potential airbag failure.
Faulty sensors. There are various sensors related to the correct deployment of the airbag. These sensors go directly into the vehicle’s computer system, and they can fail or be tripped on accident. This could lead the airbag warning light to come on, indicating that the sensors need to be inspected and the system restored.
Wet airbag module. Anytime a vehicle sustains significant water damage, usually from flooding, this could affect the airbag module under the driver or passenger seats.
