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.
