Typical airbag symptoms owners report
- Airbags failed to deploy during frontal or side-impact crashes despite significant vehicle damage.
- A recurring "service safety restraint system" warning appears on the dash, sometimes intermittently and sometimes constantly, often paired with an illuminated airbag warning light.
- Some owners saw the warning appear within days or weeks of buying a new vehicle, with dealers unable to provide a repair timeline or parts.
- Dealers have traced some cases to a wiring harness under the front seat that disconnects the SRS system when the seat is adjusted back and forth.
- Owners report dealers stating they cannot guarantee airbag deployment while the restraint system warning is active.
