2017 Hyundai Santa Fe: airbag warning light

Filed Nov 6, 2026 · Airbags, Seat belts · AZ

The passenger restraint system in my vehicle has suffered a critical safety failure, and the manufacturer (Hyundai Motor America) is refusing to remedy the defect, leaving the front passenger airbag completely disabled. The Supplemental Restraint System (SRS) airbag warning light is permanently illuminated on the dashboard, accompanied by the "Passenger Airbag Off" indicator, even when an adult is seated in the front passenger seat. A diagnostic scan performed by an authorized Hyundai dealership confirmed a catastrophic failure of the Occupant Classification System (OCS) sensor mat located inside the front passenger seat cushion. The specific Diagnostic Trouble Code (DTC) retrieved was B1490 (OCS Sensor Mat Defect). The dealership confirmed that due to this hardware failure, the front passenger airbag is completely deactivated and will not deploy in the event of a collision, posing an immediate, severe injury risk to front-seat occupants. Hyundai previously recognized widespread safety defects with this exact component and issued an 18-Year OCS Sensor Warranty Extension (Campaign Z01) to replace the front passenger seat cushion/OCS sensor free of charge. However, Hyundai Corporate and the local dealership are refusing to honor the warranty extension on my vehicle based strictly on a technicality. They state that Campaign Z01 only covers the physical replacement of the OCS sensor if the computer outputs code B1764, whereas my vehicle is outputting code B1490. Both trouble codes identify an internal, unprovoked hardware failure of the exact same OCS sensor mat assembly, resulting in the exact same hazardous condition: a permanently disabled passenger airbag. By denying coverage based on a software code variation for an identical component failure, Hyundai is failing to remedy a known restraint system defect. I am filing this complaint to document this critical safety hazard.

Airbag light on. La Quinta Hyundai verified light on scanned codes found active b134800 Driver airbag resistance circuit short to ground 1st stage. Testing found clock spring issue internal fault. Since this clock spring is related to driver airbag, & horn, it would seem that this would be a safety hazard that would be under warranty. The extended warranty (Z01) that I received from Hyundai doesn’t cover my problem.

The contact owns a 2017 Hyundai Santa Fe. The contact stated that while driving at an undisclosed speed, the air bag warning light illuminated and remained on, despite no accident occurring. The vehicle was taken to an independent mechanic who could not determine the failure and advised the contact to visit the dealer. At the dealer, the vehicle was diagnosed with a failed passenger air bag inflator that needed replacement. The dealer also found that the SRSCM (Supplemental Restraint System Control Module) required replacement due to the part shorting the inflator. The airbag was replaced, but the dealer refused to replace the SRSCM as it was no longer under warranty. The manufacturer was not notified of the failure. The failure occurred at approximately 77,000 miles.

On my Driver/passenger seat the recline switch with not go back only forward. The dealer explains to me that just diagnosing the issue is 250 then the switch is going to cost me over $800. If replace the Power Seat Switch for $49.99 and the Power Seat Switch Knob only cost $ 15 plus dollars, also to replace the motor $200-300 now my air bag light is on not sure if it's because of the seat functioning or not, my kid's car seats are right behind the seats so its concerning to me. Looking online they are hundreds of people complaining of this, but no action has been taken such as a recall.

For at least 14 months, the air bag light on the dash is on more often than not. The code that comes up on the OBD shows it's from the passenger side seat sensor. Occasionally, the seat belt indicator will flash when there is no occupant, as well. The car has never been in an accident, and the air bags have never been set off.

My engine failed. Dealership put it through an oil consumption test which it failed. They ended up keeping my car for 3 weeks to build a new engine, add new belts, new spark plugs and new filters to go with the repair. After completing this repair they told me they noticed my air bag light on. They recommended a new sensor to fix it. Which I was to pay $600 for. I agreed to this and had it done. I picked up the car and had it for 3 weeks before the airbag light came back on. I brought it back to dealership. They assessed it and told me the problem actually came from the seat and the total.to repair the whole seat would be $2500+ I am the only owner of this car. It has never been in an accident where the airbag deployed. It is in it's original state. I feel this is a huge safety concern that should be looked into.

We noticed that we had our airbag light was on in our dashboard along with that we also notice that the buttons and horn did not work in to the steering wheel. When we took the car to get checked by the Hyundai dealership in Lakewood. We were told that the clock spring was the cause of this problem to the airbag, horn, and the buttons not working. They told us that this clock spring part it was broken and it needed to be replaced. Our concern is the number one safety which making sure that all of the airbag and horn to be working. When this was communicated to the dealership person he response was that he could not say anything much about other then him saying that it was not under warranty and it was due to the mile of the car. Which I the moment we told them we totally understand about warranty and miles to the car but the safety of someone should not be put at risk just because of one part that connects all of this things. To us this is safety concern due to the airbag and horn not working. We are not sure by us reporting this would be something can be considered for a recall or be done about without costing any money to those who own a vehicle like this.
