Since the beginning of November, 2021, without incidence or prior warning, the airbag warning light came on when the vehicle is started and stays on the entire time the vehicle is on. The vehicle was brought to a KIA dealership on November 18th to diagnose the issue under extended 15 year warranty for two airbag recalls (one for clock spring and the other for ODS sensor). The diagnosis…

What stands out
No new NHTSA airbags complaint has been filed on this vehicle in over 4 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: Prospective buyers of 2015 Kia Sorento models should be aware of recurring airbag deployment failures during crashes and persistent warning light issues that may prevent detecting secondary airbag faults. Airbag repairs are expensive and often not covered by warranty, and even Kia recalls don't apply uniformly across 2015 model VINs.
Owners describe two major airbag problems in 2015 Kia Sorentos: non-deployment during crashes and persistent warning light faults.
Non-deployment: Multiple owners report airbags failed to deploy during high-impact collisions—including a head-on strike at 60 mph, a rear-impact at 75+ mph, and a severe crash into a steel billboard pole at 55+ mph. One driver suffered life-threatening injuries (broken back, spinal cord damage, head trauma, permanent facial disfigurement) because no airbags deployed despite the vehicle having eight. Another owner's infant son sustained facial swelling and bruises when struck by the side of his car seat after a 60 mph side-impact with no airbag deployment. A third reported a strong smell from the airbags after a 20 mph frontal crash where bags failed to deploy.
Warning light and fault codes: Owners report the airbag warning light illuminates during normal driving or at startup and stays on continuously. One dealer diagnosed code B1473 (Driver Curtain Airbag Circuit Resistance High), quoting $1,800 for driver-side curtain airbag replacement not covered by a 15-year extended warranty. Clock spring assembly faults also trigger the warning light, and while a recall exists for 2011–2015 Sorento clock springs, it does not apply uniformly to all 2015 VINs. Owners note a persistent warning light prevents them from detecting new airbag faults. One owner also reported the front passenger airbag turned off without explanation.

Failure modes owners describe
Airbag non-deployment in collisions
Multiple owners report airbags failed to deploy during high-impact collisions, including head-on and rear-impact crashes at significant speeds (60+ mph). In one severe case, a driver struck a steel billboard pole with no airbag deployment despite 8 airbags present, resulting in life-threatening injuries.
When: During collisions at 12,000 to 69,000 miles
Symptoms owners cite: No airbag deployment during impact; Strong smell from airbags after collision; Occupant head/body striking steering wheel, windshield, dashboard, and side surfaces
Airbag warning light illumination
Persistent airbag warning light appears during normal driving or at vehicle startup with no prior warning. Once illuminated, the warning light remains on continuously. Owners report this creates a safety concern because they cannot discern if new airbag faults occur while the warning is already active.
When: At various mileages, including 100,000+ miles and early in ownership (November 2021)
Symptoms owners cite: Airbag warning light stays on after ignition; Light comes on during steering or normal driving; No obvious cause or prior incident
Codes mentioned: B1473 (Driver Curtain Airbag Circuit Resistance High)
Repairs/costs cited: Driver side curtain airbag replacement estimated at $1,800; not covered by extended 15-year warranty. Clock spring assembly replacement costs cited as "$$$$" out of pocket.
Recalls/TSBs owners mention: Extended 15-year warranty does not cover airbag circuit resistance fault. Recalls exist for clock spring and ODS sensor, but do not resolve B1473 code on affected vehicles.
Clock spring assembly fault
Faulty clock spring assembly triggers airbag warning light. Mechanics identify this as the root cause, and a recall exists for 2011–2015 Sorento clock spring, but the recall does not apply to some 2015 model VINs.
When: Unspecified mileage; one report at approximately 100,000 miles
Symptoms owners cite: Airbag warning light illumination; Light triggered by turning steering wheel
Repairs/costs cited: Clock spring assembly replacement out of pocket; owners report cost is significant and not covered.
Recalls/TSBs owners mention: Kia recall exists for 2011–2015 Sorento clock spring assembly, but does not apply to all 2015 VINs.
Front passenger airbag disabled or malfunction
Front passenger airbag turns off or fails to engage. One owner reports the front passenger airbag was turned off when the warning light illuminated; another reports the passenger airbag will not engage (possibly due to seat design that prevents proper positioning of short-stature occupants).
When: Approximately 100,000 miles and unspecified mileages
Symptoms owners cite: Front passenger airbag turned off; Passenger airbag does not engage; No crash required

Common questions
How serious is the airbags problem on the 2015 Kia Sorento?
It's a meaningful issue. 21 complaints have been filed and the failure mode causes operational problems for owners. Repairs average $1,100.
At what mileage does the airbags typically fail?
Across the 8 complaints that reported odometer mileage, most airbags failures cluster between 22,000 and 91,257 miles, with the median around 69,000. A quarter of owners report trouble before 22,000; a quarter make it past 91,257. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $1,100 for airbags repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to airbags?
No active recalls currently cover airbags issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
