Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering airbags on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
Owners of 2015 Q50s report serious airbag failures across multiple categories. Most concerning are cases where airbags completely failed to deploy in significant impacts—multi-vehicle collisions, rollovers, and crashes at highway speeds—leaving occupants unprotected and sustaining injuries that required hospital care and imaging studies. These events occurred at various mileages (5,000 to 84,000 miles) and triggered NHTSA Campaign 16V244000, which addressed Takata airbag issues.
A second major issue is the passenger-side airbag warning light staying illuminated for 2–5 minutes when an adult occupies the front passenger seat, when it should extinguish within 7 seconds. Multiple owners say dealers found no diagnostic fault codes and offered no remedy beyond suggesting passengers sit elsewhere. One owner reported this failure recurred within days of dealer service under the recall campaign.
One owner experienced airbag deployment upon striking a sewer drain cover at 20 mph and was told repairs must be done out of pocket. Another reported chest pain from airbag deployment itself during an accident. Owners citing the Takata recall noted severe delays in parts availability, with one stating the manufacturer exceeded reasonable timeframes for the repair.

Failure modes owners describe
Airbag non-deployment in crashes
Airbags failed to deploy during vehicle impacts ranging from minor collisions to severe multi-vehicle crashes and rollover events. Owners report complete absence of deployment when impact energy should have triggered the system.
When: Various mileages: 5,000 to 84,000 miles; incidents during active driving
Symptoms owners cite: No airbag deployment on driver or passenger side during impact; Airbag warning light illuminated at moment of impact; Vehicle damage extensive with no corresponding airbag deployment

Passenger airbag warning light stays on with adult occupant
Passenger airbag status indicator remains illuminated for extended periods (2-5 minutes) after an adult occupies the front passenger seat, when it should turn off within 7 seconds. Dealer diagnostics show no fault codes, but owners report concern the airbag would not deploy if needed.
When: Early in vehicle ownership; one report at 21,000 miles
Symptoms owners cite: Passenger airbag warning light remains on for 2-5 minutes with adult seated; Light should turn off within 7 seconds per normal operation; System message indicates airbag is turned off when light is on; Failure recurred after dealer service under recall 16V244000

Recalls/TSBs owners mention: NHTSA Campaign Number 16V244000 (Air Bags). Dealers reported no codes present; customer service unable to help. Repair attempt under recall did not resolve issue.
Airbag deployment on minor impact
Driver-side airbag deployed when vehicle struck a sewer drain cover at low speed (20 mph). Owner questioned whether deployment was appropriate for this type of contact.
When: 84,000 miles
Symptoms owners cite: Driver-side airbag deployed upon striking sewer drain cover; Front seatbelts locked as designed
Repairs/costs cited: Dealer stated vehicle needed diagnosis to determine cause; vehicle not repaired. Manufacturer told owner repair must be done out of pocket.
Recalls/TSBs owners mention: Manufacturer contacted and informed owner out-of-pocket repair required.
Airbag deployment causing injury
Airbags deployed but caused painful injuries to occupants' chests instead of providing protection, suggesting potential issues with deployment force or timing.
When: <UNKNOWN>
Symptoms owners cite: Airbags deployed during accident; Occupants sustained painful chest injuries from airbag deployment; Injury described as painful rather than protective
Recalls/TSBs owners mention: TAKATA RECALL mentioned but no details on manufacturer response provided.
