What stands out
Among the 5 model years of Cadillac STS in our records for airbags problems, this one ranks #3 by owner-complaint volume.
No new NHTSA airbags complaint has been filed on this vehicle in over 8 years — the issue may be aging out of the active population.
The failure pattern owners describe
The 2005 Cadillac STS airbag system generates repeated failures across this complaint cluster. The dominant issue is the service airbag warning light coming on and refusing to go off—either staying lit continuously or cycling on and off. Owners report the light triggers when the driver's seat moves, and reset buttons don't clear it. One owner noted burnt wires under the seat when troubleshooting the light themselves, raising fire concerns. Another found their defective airbag module replaced with an identical manufacturer's part that failed again.
Two separate crash incidents resulted in complete non-deployment: one at 45 mph into trees, another unspecified. The GMAC claims rep told the first owner non-deployment was "normal," a statement that contradicts basic airbag function.
Dealers refuse warranty repair, demand diagnostic fees without including repair cost, or quote repair bills matching the vehicle's value. Cadillac recalled the identical fault on 2005 CTS models and newer STS model years, but will not extend coverage to the 2005 STS. One complaint mentions a Takata recall tied to the same vehicle. Owners emphasize they're driving cars with disabled airbag protection and no manufacturer support.

Failure modes owners describe
Airbag warning light malfunction
Service airbag or airbag warning light illuminates on dashboard and either stays on continuously or cycles on and off. Owners report the light comes on when starting the engine or unprompted while driving. Reset buttons do not clear the fault. Dealers often refuse warranty repair or demand diagnostic fees without including repair cost in estimate.
When: At 55,000 miles and up; 70,000 miles reported on second occurrence in same vehicle
Symptoms owners cite: Service airbag or airbag warning light illuminated on dashboard; Light stays on continuously or cycles on and off; Light appears when moving driver's seat; Reset button ineffective at clearing fault
Codes mentioned: B0022
Repairs/costs cited: Dealers quote repair costs as much as vehicle value; seat belt pretensioner replacement mentioned but dealer declines to cover; defective airbag module replacement cited as failure (replaced module failed again with same manufacturer's part).
Recalls/TSBs owners mention: Recall ordered for one or two years newer model years with identical issue; 2005 CTS models recalled for same problem but 2005 STS not included; Takata recall mentioned in complaint #11
Airbag non-deployment in collision
Airbags fail to deploy during vehicle crashes despite the airbag system being operational enough to illuminate warning lights in other cases. Two complaints report accidents where airbags did not deploy, leaving occupants unprotected.
When: During accidents at impact speeds described as moderate (45 mph in one case)
Symptoms owners cite: Airbag does not deploy on vehicle impact; Vehicle struck objects (trees) without airbag activation
Recalls/TSBs owners mention: GMAC claims representative stated non-deployment was normal; no recall or warranty action noted
Airbag wiring degradation or burnt wires under seat
Owner observed burnt wires under the driver's seat correlated with airbag warning light appearing. Similar issue found in online video of same problem on same vehicle model. Fire hazard suspected but not confirmed.
When: Occurs when driver's seat is moved
Symptoms owners cite: Airbag warning light appears on dashboard when seat is moved; Light disappears after moving seat back and forth multiple times; Burnt wires visible under driver's seat (reported in owner video)
Repairs/costs cited: Owner unable to fully inspect wiring; no repair cost provided
Seat belt pretensioner inoperability
Passenger seat belt retractor becomes inoperable and will not retract when needed. Occurs in conjunction with airbag system fault code B0022 and service airbag warning light.
Symptoms owners cite: Passenger seat belt will not retract; Service airbag warning light stays on continuously
Codes mentioned: B0022

What owners are reporting 2 most recent
When I move the driver's seat the "airbag" symbol appears on the dashboard. If I move the seat back and forth , after a few tries, the "airbag" symbol disappears. I was not able to look under the seat, but I have seen a video where somebody had the exact same problem but found burnt wires under the seat. I am wondering if there is a fire hazard. This happened when the car is stationary.
