general problems of the 2018 Kia Motor Sedona

Since shortly after buying the van we have been getting airbag warning lights. Just about every part of the system has been replaced, but the airbag light still comes back on. Just got the van back from the dealer today for the 9th time, and after about an hour of driving, the light is back on again.

I have the air bag indicator light and the diagnostic codes consistent with NHTSA campaign number 19v109, kia recall number sc175. The recall mentions the wiring harness being damaged and my harness is damaged, with two wires severed. However, because my vehicle was manufactured 2 months after the recall cutoff date, kia believes this recall does not pertain to my vehicle. I believe otherwise.

My daughter was driving my kia Sedona van - distracted and on wet roads ran into a firehydrant and pole. During the accident, the air bags did not employ. The passenger fell forward and broke the windshield with her head, leading to a concucussion. We are thankful for two children who are alive after this accident. We are disappointed tho that the airbags didnt protect our child more.

In 2022, our airbag light came on. On 5/10/2022 am airbag recall was issued and it was fixed. The airbag computer/module was fixed. We got into an accident in August of 2022, and our airbags never went off. And the airbag light has never shut off since it was “fixed” may 2022. It’s now October 2025. They said nothing was wrong with it, after bringing the vehicle in multiple times. And now after bringing it in, again in August 2025, they said the entire passenger airbag unit needs to be replace and isn’t related to the airbag recall. It’s $800+ and kia won’t do it since the warranty has expired and it’s “not related”. Still fighting with them over it. As the airbags recall in 2022 included a defect where the airbag control unit (acu) cover can contact a memory chip, potentially deactivating the airbags. This issue affects a range of models manufactured between July 2016 and January 2019 and can result in the airbags failing to deploy in an accident. Worst customer service and vehicle I’ve ever owned.

The contact owns a 2018 kia Sedona. The contact stated that the air bag warning light was illuminated. The vehicle was taken to the local dealer where it was diagnosed and an unknown software was updated however, the vehicle was not repaired. The contact was informed that the air bag needed to be replaced. The manufacturer was notified of the failure but provided no additional assistance. The failure mileage was approximately 73,000.
