I was involved in a accident on December 15, 2015 the other driver cut across three lanes and into my car at mph 40. My vehicle was struck thrusting it into a small wall and pole. My seat belt unbuckled and the airbags did not deploy I think this is a manufacture defect.

The light of passenger air bag sensor constantly on. The passenger seat pad was already changed by the dealer on a recall., however the sensor light is still on. Consumer does not know if air bag will deploy or not. This might be considered a serious hazard. The dealer will not recognized gravity of situation or perhaps denied it. The passenger seat sensor light will be constantly on whether the car is stationary or in highway.

Air bag light came on in the dash at approx 86,600 miles; for no apparent reason. Also noticed that the passenger seat belt sign near the center console is flashing even if there is no one seated in the passenger seat.

My 2006 Sonata only has 65,000 miles. But the airbag light always on from this year and brake line was rust. For the airbag, the light in dashboard is on when car starting, and the passanger airbag is off even if someone sitting on passanger seat. For the brake, the front brake line was rusted last year and all the brake oil is totally leak out, so there is no brake when driving it. And the rear brake line is broken this year due to rust. I am in freeway when the rear brake leaks, so image how terriable it is. Never seen this from other 10 year old vehicles.

My airbag light and passenger wear belt light came one even when an adult is sitting in the passenger seat. The car had never been involved in an accident so I don't know why the air bag light came on.

My airbag light randomly came on last week and has not gone off since. I have never had any lights on my dash board illuminate. The mechanics are quoting ridiculous prices to fix it and I am nervous to drive it with the light on.

Sensor in passenger seat cushion not working properly and will cause the airbag and seat belt light to illuminate and also causes the airbag to not deploy upon impact. This is a problem that should be a recall issued from Hyundai as there are millions of people that have this same complaint.

On Nov. 7, 2013, I notified Hyundai that we had been experiencing problems with the Sonata's occupant classification system (OCS). The system did not consistently recognize my wife as an adult passenger, even though she clearly exceeded the necessary weight threshold designed to activate the airbag sensor. Hyundai, after mechanical/electronic review, stated the OCS was working as designed. It wasn't. we returned the vehicle for service on April 1, 2014, and again on May 22, 2014, only to have Hyundai tell us the OCS was operating "ok". again, on July 30, 2015, we returned the vehicle for service, as the OCS was still malfunctioning. Hyundai, at that time, performed a reprogramming. Still the OCS does not consistently recognize my wife as an adult passenger. I have contacted Hyundai an almost innumerable number of times in regard to this issue. Though Hyundai even had an arbitrator document the defect, to date we still have no resolution. It is unsafe for my wife, or any other adult passenger, to ride in the car. And, as one can see by the history, it has been that way for quite some time.

In the mid of April, I received a extended warranty letter from Hyundai for my "air bag" light that has been on. It was for the air bag light due to resistance within the connector for the front seat belt buckle. On April 27, 2015 I scheduled my first appointment at savannah Hyundai. On invoice it stated: 135681 check and found history codes B1701 drivers seat buckle pretensioner resistance high B176 passenger seat buckle resistance clear codes no codes reset. I was told the problem was fixed. As I drove off the service lot, my air bag light went back on. On May 4, 2015, I went in for another diagnosis and was told that they needed my car to stay at the shop and they gave me a rental. They said they needed to send my seat off to be fixed. It was a few days that they had my car. On that invoice it stated: Check air bag system for codes B1701 and B1706 driver and passenger front seat belt buckle pretensioner resistance high found service bullentin 15be002 install tie strap on driver and passenger seat belt buckle pretensioner connectors.on June 22, 2015 I came in savannah Hyundai once again because my air bag light warning came back on. I was told that my warranty was already extended was no longer under warranty and I would have to pay out of pocket if I wanted to fix this problem with my car. Which I had the extended warranty and had no idea why they were fighting with me with this. Fix the safety issue! on invoice it was noted that the tsb for pretensioner connectors were already performed and that the vehicle needs passenger buckle pretensioner and the tsb does not mention any warranty covering the replacement, only the zip tie installation. I called corporate and on May 29, 2015, they ordered the passenger seat buckle pretensioner and supposedly they fixed the issue. Today is July, 15, 2015 and my air bag warning lamp is on once again. I am very disappointed.
