AIR BAG light is on, with defect in Occupant Classification System (passenger weight sensor), with OCS system lights flashing erratically with no passenger in seat.

There is information for "Campaign 083 - 2006 - 2008 Sonata - Occupant Classification System (OCS) Reprogramming" online. Internally labeled as 08-01-006 Body Electrical issue. Campaign clearly states that problem is to be fixed on individual customer basis, meaning it wouldn't show up as a official recall. Hyundai currently refuses to take responsibility.

On July 19, 2016 at or about 1500 hours, I was driving to the store to get some food, on the way out my apartment complex, I believe my Hyundai Sonata 2008 allowed me to go about two blocks down from where I live to shut off in the street right before I approached the stop sign. I also remember hearing two weeks prior to my vehicle shut off, while driving I heard this knocking sound in my engine, I thought it was the new starter that was replaced but then a day or two later it stop making that knocking noise. I called around to find answers no one had a clue to what was going on with this vehicle. Everything was working just fine until July 16, 2016. I had this vehicle since April 17, 2009 and I can't not believe this vehicle has a major issue like this at point and time. …
My car only has 82,000 miles on it and I am the second owner. For some reason the airbag light came on. I received an extended warranty notification earlier this year in regards to seat buckle assemblies on 2006-2008 sonatas, which applied to my car. At that time however, I had no issues with the airbag light but now the light has come on. I went to the dealer and they stated that my issue has nothing to do with the seat belt buckle however it has to do with a b1448 080 (occupant classification system) (mat defect) I have spent some time doing research and it appears that a number of people have been experiencing this issue. I am not sure whats going on here but I think we need to look into the air bag issue. …
The morning of the flash freeze on February 21, 2014, my daughter was turning left at an intersection when she lost control of the car due to slick roads. When she stepped on the brake, it slid and crashed head onto a traffic light pole. Part of the traffic light broke off as a result of the impact. Her airbag did not deploy. Her chest and mouth hit the steering wheel. She was in a lot of pain and it hurt her to breathe so was sent for x-rays. She didn't have any broken ribs but May have had internal bruising because she needed physical therapy for several weeks and a chipped tooth. When I called Hyundai and told her what happened, the representative said the airbag should have deployed. I was mailed out paperwork to fill out. I completed all the requested information. They then inspected the car. …
