After 50,000+ miles on our 2008 Kia Optima the passenger "air bag" light would come on (meaning the air bag was automatically turned off by the car's computer system) while driving with a passenger in the front seat. It would intermittently happen...sometimes it would and sometimes it wouldn't. we had it checked by a dealer and even though they saw the problem (passenger sitting in front seat and air bag was "off") it did not register a code in the car's computer system. This was reported to Kia by the dealer but as of this date (09/11/12) Kia has refused to repair the issue under warranty because it did not register a code. This poses a safety risk to passengers in the event of an accident. Failure to repair this issue could result in serious injury and even death. Kia has had this problem in other models and has even issued recalls but at this point has refused to fix our vehicle under the warrant contract we received when buying this car new in 2008.

The contact owns a 2008 Kia Optima. While driving approximately 25 mph, the air bag inadvertently deployed with substantial force and struck the contact in the face. The impact of the air bag deployment knocked the contact unconscious for several minutes, which resulted in the vehicle crashing into an unoccupied parked vehicle. The contact sustained injuries to the head, neck and shoulder. The vehicle was completely destroyed and towed to an authorized dealer. A police report was filed of the incident. The manufacturer was notified of the problem. The approximate failure mileage was 43,040. Updated08-30-12 updated 09/07/2012

As the driver's side air bag assembly is under a recall, the passenger side system should also be investigated. About 10-15% of the time the passenger side air bag will indicate that it is off after an adult sits in the seat. This requires that the person will need to get out then back in, or the car needs to be shut off and restarted and that doesn't guarantee that the system will operate properly. Last week the passenger side air bag off light has now been coming on while the car is in motion. It will appear for a few seconds, then go off, reappear then go off.

After clockspring recall/ and repair the cars air bag signal now come on with a code of B1378 in which Kia has told me that there is S high resistance dsab. I have been informed that this code is for a bad or faulty airbag. The car has never been in an accident and the airbag has never been deployed.

We were hit in the passenger side and the entire side of the car was crushed and none of the air bags ever deployed and the passenger side seat belt did not lock. I had reported the fact that when someone was sitting in the passenger seat that the airbag light was not coming on to the car dealership that I purchased the car from but they just made excuses that the person sitting in the seat was not heavy enough even though they weighed over 150lbs.

The contact owns a 2008 Kia Optima. The contact stated the air bag warning light illuminated only when someone was sitting in the passenger seat. The vehicle was taken to a mechanic who stated when the light was on it indicated that the air bag may not deploy in a crash or it may deploy without a crash occurring. The vehicle was not taken to a dealer for diagnostic testing. The failure mileage was 69,000 and the current mileage was 75,000. Updated 06/26/12 a diagnostic revealer the oc passenger sensor mat was defective. The problem was corrected. However, three days later when a passenger sat in the seat, the air bag light illuminated on the dashboard again. The consumer returned to the repair shop again. The mechanic stated it seemed that if someone sat in the passenger seat, did a lot of moving around, or was slightly heavy in weight, it triggered the air bag light. The consumer stated the light is currently on. Updated 06/27/12.

December 28, 2011, I noticed that my airbag light located on the dashboard continuously stays illuminated. I have taken it to the dealer to get it checked out. I was told that the airbag sensors are located in the driver/ passenger seats. The mechanic at Kia dealer tried to fix the problem, but was unsuccessful. The service representative informed me that they would have to replace the sensors. I've viewed the complaints of people that own Kia Optima 2008. It states that these cars were recalled because of significant amount of defects. (I only have 43,000 miles) in addition, a week ago I've started hearing a ticking noise coming from the engine area when I accelerate going up in a roller coaster climbing position. Thank you for your expeditious response.

When front seat passenger sits in the passenger seat of the 2008 Kia Optima, the airbag "off" indicator doesn't switch to on. I was told by dealer that the steps is that the car needs to be off, passenger sits, then turn the car on. This automatic feature is going to get someone killed... not turning on the passenger restraint. Unless the car is off. True situation - my wife gets discharged from hospital from having a baby, I pull car around, get out, load items in the car. My wife gets in the car. Half way home, we realize the front passenger airbag is "off."

The passenger side airbag malfunctions. It may or may not engage when one sits in the seat. After moving around; getting out of car and/or refastening seat belt it will most of the time engages. The size of the person, the movement of the car (or not), and sitting position do not appear to matter. One knows that the airbag is not employed properly because the light indicating the functioning of the passenger side airbag will read "off."

There were no repairs made to the vehicle. The failure and current mileages were 32,000.
