Airbag warning light remained on after starting the vehicle recently. Vehicle was diagnosed on August 31, 2015 by local Hyundai dealership (where purchased). Results of diagnosis stated on service description "code in acu for OCS module. Recommend replacement of passenger seat bottom". it was stated that with the airbag light on, the service department could not guarantee airbag would work. So we immediately ordered recommended airbag parts. ( front passenger seat bottom) at a major cost of $1,246. And labor cost of $165. Parts came in and were installed on September 9,2015. Airbag light is off. This safety system needs to be investigated for root cause and corrective actions. With only 81,319 miles, this falls way short of long term performance.. with safety of my family at stake with this issue I had no other choice but to get this issue fixed. Plus it would not pass state inspection. Last I have seen several other reports of airbag lights on for Hyundai Sonata 201, same problem.

- Kernersville, NC, USA

Front passenger weight classification sensor failure. Dealership says the only why to fix it is to replace seat for $1800. Dealership cannot tell me if SRS will work when needed. After doing so research online this looks like a big problem with hyundal cars throughout many model years. Hyundai has failed to remit this problem and is selling vehicles to the public with faulty air bag systems.

Sensors cause air system light to illuminate. System needs to be reset at dealership to clear. Technician said airbag won't deploy while this fault occurs. I have had this issue 4or 5 times. When I google Hyundai Sonata airbag issues I see many similar experiences with other people. This could be a potential safety hazard. I was told it was caused by a seat sensor. Yet under warranty they did not replace. No car is out of warranty.

2011 Hyundai Sonata was on 2nd recall for transmission. The air bag light came on and would not turn off...updated 02/12/15

- West Covina, CA, USA

I have had so much warranty work done to this car, that I will never buy Hyundai again! I would estimate around $10,000 worth or warranty and recall work has been done, not including the other issues that are not under warranty. My airbag pressure is too high so the light is on, on my dash. It's a $300 job and then there is some sensor for the gas that causes the check engine light to stay on. That's another $200 to get fixed. Also the motor in my driver side window is going out. Seems like there's just one problem after another. I'll never will buy Hyundai again and can't wait until I can afford to trade this Sonata in.

Airbag sensor has been illuminated stating that there is an error with the airbags. Concerned that airbag wont function in case of an accident.

- La Puente, CA, USA

This vehicle has a manufactured defect and has been rejected by a state certified state inspector. It was failed due to the air bag light continued to show on the dash board. The state inspector indicated that this vehicle would not pass inspection until the air bag situation has been resolved. I am not concerned if other Hyundai vehicles are recalled or not. My primary concern at this present time is my 2011 Hyundai Sonata limited is taken care of in accordance with the requirements of the national traffic and motor vehicle Safety Act. I have asked Hyundai to repair this vehicle. However, I was told that the warranty has run out on this vehicle. I indicated that this is a manufactured defect and should resolved immediately.

- Petersburg, VA, USA

I was rear ended while at a stop by a large truck that was going 40 mph. My airbags didn't deploy, which didn't surprise me, but my seatbelt did not properly engage. When I was rearended, I went forward and my head hit something, possible the steering wheel. The seatbelt finally engaged and strapped me back to the seat. Due to the failure of engagement, and my head hitting an object, I sustained a substantial concussion due to the head trauma and have post concussion syndrome which is greatly effecting me at home and at work.

Hello, I'm not sure if this qualifies, but this vehicle has a major defect in the compressor kicking on for air conditioning (per my own experience and examining forums of other users). The A/C does not come on intermittently, especially when the car hasn't been turned on for 3 or 4 hours. This can be a major safety concern in warm areas.

- Statesboro, GA, USA

My vehicle hyndai Sonata 2011, crashed into a parked construction in a parking lot at the speeds of up to 30 mph. The crash damaged basically the whole front side of the driver side and damaged the front two wheels. The front windshield was damaged as well with cracks on the shield and it also knocked out the rearview mirrors. I was in the driver seat when the crash happened and my head crashed up against the steering wheel, which left a little soreness. What I was wondering is with such an impact and such damage, how did the airbags not go off". my head slammed pretty good up against the steering wheel and a little more impact I could've been severely hurt. So I just want to ask why did the airbags not work"

Tonight I was rear ended by a woman in an SUV, who's brakes did not work in her durango, she said. There were no skid marks indicating an attempted stop. Her impact on my vehicle was severe. Police officer guessed she was going 40 mph when she hit my car. My car was shoved forward into the car in front of mine, that car then hit the car in front of it. There were 3 cars, mine last in line, sitting at a red light. We were all stopped. Then there was a 4th car that hit mine from behind. The matter im reporting is that the airbags in my Hyundai Sonata SE 2011 car did not deploy when I then hit the car in front of me. The impact was great enough to cause that car to then hit another car and that caused a crack in the radiator of the car in front of mine. Also, after I hit that car in front of me, I then bounced back about 10 feet. More evidence of impact. Why no airbags? I did not see very much damage to the front of my car nor the back of the car that was directly in front of mine, while the back of my car was bad enough that I expect to be told it is not repairable.. im reporting just in case you receive any other reports indicating there is something faulty concerning airbags in the Hyundai. I know airbags are not to deploy in rear end collision but since I then hit another car frontally, I would think the airbags would deploy. My husband was in the passenger, front seat and in order to brace himself, he put his hand up at the windshield. The glass was broken in an area the size of a cantaloupe from the impact against his hand. Im thinking the impact must have been moderate to severe. On the up side, my Sonata took that hit and sustained the damage to the outside and up into the air at the trunk rather than into the cab of the car. My father and son were in the backseat and were not killed, I think because the car is a good, safe vehicle in a crash.
