The airbag light stays on constantly - mechanic says it's the switch in the passenger seat belt and they encounter this problem with this vehicle all the time. Prevents the airbag from deploying if not repaired.
Airbag light is constantly on from the time I start the car, until I turn it off, mechanic stated it was the passenger seatbelt buckle switch. I've seen many posts online about the same exact thing happening to them. It poses a safety threat, as the airbags are not going to go off.

Unable to depress brake pedal. This is the third time in twelve months that this has happened. Last May 2014 I was in grand rapids michigan going about 45 and the same thing happened I kept moving over to a clear lane on my left trying to depress the brake and had to turn into the median and do a u- turn, the car rolled to a stop. I got out and checked under the pedal and there were no obstructions. I checked the brake fluid reservoir at the master cylinder and it was full. I got back in the car and tested the brakes and found them to work. I called my Hyundai dealer and had them look the car over and they had no explanation. Yesterday I was in stop and go traffic approaching a line of traffic and the same thing happened, I did not think to use the emergency hand brake but the good news no damage. …
Tl* the contact owns a 2005 Hyundai Santa Fe. The contact stated that the air bag warning indicator was illuminated. The contact associated the failure with NHTSA campaign number: 05V450000 (air bags). The vehicle was taken to sheehy Hyundai of waldorf (located at 2910 crain hwy, waldorf, md 20601, [phone]) to be diagnosed, but they were unable to duplicate the failure. The vehicle was not diagnosed or repaired. The manufacturer was notified. The failure mileage was 187,880. Consumer stated issue was reported in 2010/11. It is also related to buckle seat belt. The vehicle was still under warranty. Consumer called the dealer and they agreed that they have the name of the consumer but their system can't retrieve service details.

My moms Santa Fe has sped out of control several times in the last three months. The last incident caused injuries because the air bag failed to deploy. The first incident was in a parking lot where the car had unintended acceleration and crashed into several cars. Second incident was on the road where car sped up and she turned it off. The third was backing out of a shopping center parking lot where the car rapidly accelerated in reverse hitting a car and then tried to put in neutral but went into drive instead. She hit a post and the front end wrapped around the post but air bag did not deploy causing injury. State farm and many attorneys won't touch this case because of the costs involved to sue such a large corporation.
Drivers chest seat belt is loose and the sensor in the seat belt you snap and lock it in place makes the "air bag" light for the driver only come on. I've had it diagnosed and checked by a licensed mechanic, and was told the seat belt is defected, and currently, as long as the "air bag" light remains on, even if they turned it off, the drivers air bag would not deploy if impacted hard enough in vehicle collision. The air bag is okay and in working condition, its the sensors in the seat belts in the driver's seat that are out of date. The "red light" remains on from the time I start the vehicle and its in park, idling, moving, up until we are back idling, and the engine is off.
I took my car to get checked after a air bag light came on at the dealership. After their diagnostic they want to charge me $2500 to fix a seat belt buckle and a sensor under the occupant seat. I have had this car under a year and do not have the type of income to correct this asap. The light is keeping me from getting my car inspected which in the long run can cost me my job. I called the phone number here provided here to be told 61 cases have been reported with the same complaint. This needs to be recalled. This is the second problem I have had with this car,the first being a recall on the coil springs. I was driving when this light came on.
