The airbag light randomly came on 2 weeks ago and stayed on , indicating that the airbags would not deploy in the event of an accident. I called my mechanic, who confirmed it was not a warranty item. My car only has about 45,000 miles on it and is well maintained. it has never been in an accident. I dropped my car off with my mechanic, who is waiting on the needed part, but noticed after I dropped it off that other Kia models have been subject to a recall for this same issue. My guess is that not a lot of people purchased Kia Cadenzas, so maybe this flew under the radar. I am looking at a repair bill in excess of $2,000 because of the cost of the part and the time it takes to access and diagnose the problem. Kia must be aware of this.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your
pre-purchase inspection list. Back to the
