NHTSA Complaint #11478910 — 2006 HYUNDAI SONATA

Passenger occupant classification sensor fails to properly identify whether an adult or child is sitting in the front passenger seat causing the airbag to deploy when it shouldn't. If a child is in the front passenger seat and we get into an accident, the child could be hurt or killed by the airbag. We brought it into the Hyundai dealership after receiving a recall notice that it may fail to properly detect whether a child is in the seat or not. At the time of the recall, the dealerships instructions were to place a certain amount of weight on the seat and if the airbag was still disabled then it was determined to be working correctly. I have since been made aware of a Hyundai TSB that came out a couple of years later that stated in all cases the seat cushion was to be removed and sent back to Hyundai for recalibration. In June 2021 the airbag light came on due to a code B1448. In September 2021 I found another TSB by Hyundai stating that they have extended the warranty on the passenger OCS to 15 years, unlimited mileage. The inspection report for the B1448 was on June 7, 2021 and we purchased the car in July 2006. When I called the closest Hyundai dealership regarding the issue they said I was 2 months past the 15 year warranty and there was nothing they could do. I explained that that the code presented itself before the 15 year warranty. It upsets me that I took it in for the airbag recall and the faulty OCS was not replaced at that time. Now I'm stuck driving around a car with the airbag light on or purchase an OCS emulator to fool the system into thinking there is someone sitting in the seat. While this won't fix the problem of the airbag deploying when it shouldn't it doesn't fix the root cause of a faulty OCS mat that Hyundai is well aware of. The vehicle is available for inspection.
