2018 Hyundai Santa Fe Sport: airbag warning light

Filed Aug 26, 2025 · Airbags · FL

The passenger airbag sensor is malfunctioning and does not recognize that a passenger is in the car. The dealership advised that they don't know if the airbag would deploy if an accident occurred, which presents a risk to passengers. The airbag light stays on all the time. The dealership performed the diagnostics on the vehicle on 2/5/2025 and confirmed that the sensor was malfunctioning. They advised that the parts were on back order (88104-4Z591-VAS and 88952-4Z500). We still have not been able to obtain both parts as of 8/26/2025. We have contacted dealerships in other states who advised that they've been waiting on these parts for over a year. We are unable to fix the vehicle, and it is unsafe to drive with anyone in the passenger seat. We opened an issue with Hyundai Corporate, but did not receive any resolution. We were told that they would reimburse us for the cost of a rental when we needed to transport additional passengers. They later denied our request because 1) They claim it is not a safety-related issue, and 2) it occurred outside the state where we initially took the vehicle to the dealership since we are on a long-term work assignment and temporarily living in another state.

The day after I purchased this 2018 Used Hyundai Santa Fe, the passenger air bag light came on. July 2024. I have been working with the dealership where I purchased the vehicle (Larry H Miller Chevrolet, in Murray Utah), and calling Hyundai Corporation for months. Hyundai called me every 3 days for almost 3 months with a customer update and they would say is "We have no updates". This is extremely frustrating. The main idea Hyundai Corporate office is telling me is that they don't have a contract with someone that would provide the vehicle part to fix this issue. They don't have a car part available in existence to fix this issue. This is a huge safety concern. I asked them "does that mean my passenger airbag could randomly go off while I'm driving down the road, or does this mean that my passenger airbag won't go off in case I got in a wreck?" They said that it could mean a number of things, but at this time, do not put anyone in the front seat of my car. The car part is a passenger airbag plate sensor that is underneath the passenger seat. Hyundai said there are no after market parts that are sufficient enough to put into the vehicle. Especially with it being a safety issue. How can this be on the consumer??? This is very crippling. This is a huge safety concern with no timeline for resolve. I am very mad. I have been fighting this for 9 months now.
