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 report 14 incidents involving 2015 Kia Soul airbags across a range of crash severities. The core complaint is non-deployment in crashes that should have triggered airbag systems—vehicles hit at speeds of 30–65 mph in head-on collisions, rear-end impacts, and sideswipe incidents. One owner reported airbags deploying unexpectedly after hitting a pothole and causing a flat tire.
Several incidents involved significant trauma: broken ribs, punctured lung, concussion, head injuries, eye bruising, and whiplash. In multiple cases, seat belts functioned (bruising from pretensioner), yet airbags did not. Owners note the disconnect—friends' vehicles deployed airbags in lower-speed crashes. Some crashes resulted in total-loss vehicles; others were reported to insurance or police. One owner had the vehicle recently serviced for unrelated recalls at a Kia dealer before the non-deployment incident. Mileages ranged from 4,709 to 97,000 miles. No owners reported manufacturer callback or explanation. One incident involved brake failure preceding the crash. One low-speed parking-lot collision with minimal damage had no deployment and no injuries. The pothole incident was the only report of deployment, but under questionable circumstances not typical of crash deployment.
Owners perceive a systemic pattern suggesting defective airbag sensors, wiring, or control modules rather than individual manufacturing defects.

Failure modes owners describe
Airbag non-deployment in moderate-to-severe frontal crashes
Airbags failed to deploy during head-on collisions, rear-end impacts at 30–65 mph, and multi-impact accidents (rear strike, roadway departure, barrier/object contact). Vehicles experienced significant structural damage, total losses, and occupant injuries despite impact severity warranting deployment.
When: Various mileages: 4,709 mi, 10,500 mi, 18,000 mi, 97,000 mi; one recent after dealer recall service
Symptoms owners cite: No airbag deployment in head-on collision at high speed; No deployment after rear-end strike at high speed; No deployment after hydroplane and concrete barrier impact at 65 mph; No deployment in multi-impact sequence (rear-struck, roadway departure, rollover); No deployment in sideswipe/t-bone collision at 30–35 mph; No deployment in crash into eighteen-wheeler at 65 mph; No deployment in low-speed parking-lot incident
Repairs/costs cited: Vehicles totaled; body shops found no obvious component failure; insurance and collision facilities took vehicles to auction or repair lots; no diagnostic work reported by owners
Recalls/TSBs owners mention: One owner stated manufacturer was called but contact not returned; most owners did not contact manufacturer or dealer post-incident
Unexpected airbag deployment after tire damage (pothole impact)
Airbags deployed when vehicle struck a pothole, went flat, and lost stability. No crash collision occurred—deployment triggered by a non-impact road hazard.
When: Single incident; mileage not stated
Symptoms owners cite: Airbags deployed after hitting pothole and experiencing tire failure
