Owner reports
Selected complaints filed with NHTSA by 2007 Hyundai Sonata owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2007 Hyundai Sonata. The contact stated that the airbag warning light was illuminated on the instrument panel. The contact then received notification for NHTSA Campaign Number: 08V161000 (Air Bags). The contact called the manufacturer who set up an appointment with a local dealer for the vehicle to be serviced. The dealer informed him upon arrival that they were going to decline to repair the vehicle. The manufacturer was notified of the issue and informed him to ignore the warning lights on the instrument panel. The vehicle had yet to be repaired and remained in the possession of the dealer. The vehicle had yet to be repaired. The failure mileage was approximately 90,000. Consumer stated he received 2 letters regarding 2 safety recalls dealer refuses to repair it. One is passenger seatbelt light is the other airbag light.
Red "airbag" light on dash illuminated while driving. Code read as B1706: passenger buckle pretensioner. May have been covered under Hyundai's 15yr/250k warranty but owners never notified since not official recall. Although, this defect may not affect airbags themselves it causes "airbag" light to remain illuminated until addressed. Driving with the "airbag" light continuously illuminated may pose risk to unsafe conditions due to unknown new airbag codes since "airbag" light already illuminated with buckle pretensioner code B1706.
Air Bag light is ON due to bad OCS - OCCUPANT CLASSIFICATION SYSTEM on the passenger seat. It is a safety issue and airbags wont deploy in case of an accident. Passenger seat bealt light is blinking even withoit passenger. Problem has been confirmed by the service center and reported to the manafacturer. There is an open campain 083 for Sonatas with this issue but not all vehicles are included, VIN of my vehicle is not included even if it has the same issues as described in the campain.
The air bag warning light (remains on constantly) and passenger side seat belt warning lights remains on even with a passenger above the weight limit. The air bag warning light will not turn off and the passenger side seat belt light will not turn off even when the seat belt is hooked up. There is a recall for faulty sensors, recall notice, 08V161000, for 2006 - 2008 Hyundai sonatas but my 2007 is not covered? I feel like my Sonata has many of the issues in past recalls but for some reason isn't included in them (outside lighting, ESC light periodically kicking on, brake sensor failing numerous times, continuous issues with rear brakes, etc.) I think Hyundai should expand this airbag recall as I hope we aren't being put in harms way with an unexpected airbag failure when we need it most.
The air bag warning light and passenger side seat belt warning lights come on when I start the car. The air bag warning light will not turn off and the passenger side seat belt light will not turn off unless the seat belt is hooked up. I understand that these May be issues associated with faulty sensors. This is particularly disconcerting because I've reviewed the issues on-line and it's possible the air bag system May not be operating properly. I've seen that other Hyundai owners have tried to deal with these same issues and gotten little or no satisfaction from their Hyundai dealership. There was an extended recall notice, 08V161000, associated with the passenger side air bag for 2006 - 2008 Hyundai sonatas but my 2007 is not covered? Is there a way to find out why that is?
I first noticed the valve cover gasket leaking onto the alternator at about 121,000 miles and at 140.000 miles I had the valve cover gasket replaced, thermostat, intake plennom gasket also. And had the alternator replaced after it failed because of the oil leaking onto it at 156,092. Luckily I just drove by my mechanics garage at about 50 MPH and about a mile passed his garage the car started to buck and stall and all the dash board lights were flashing along with the cd turning on and off along with the seat belt light which was flashing on and off when it was buckled for about 1 month prior to this failure. I actually made it to his garage before it shut down in his parking lot.
The air bag turns on and remains on. I found out that there has been a warranty extension for this vehicle, however, when I visited the dealership they simply sent me away stating that they don't have the parts and Hyundai is still working on it. It seems like Hyundai dealers are sending away customers without taking any responsibility or at least trying to order the part. My airbag light is still on and this is a safety issue that dealers are simply avoiding to address. The dealer did not even bother to check the car with a diagnostic tool, as soon as I mentioned the warranty extension they simply said they do not have the parts.
Our 2007 Sonata air bag red light came on for no reason, just as hundreds of others have said while researching the problem on the internet. Probably will not attempt to get help from Hyundai at this point since so many others have been charged $400 plus for repairs that only last for a short time, and need to be done again. Always liked this car till this issue started. Because of Hyundai's disregard for the safety of those who own their vehicles, I will be selling this car, never buy from Hyundai again and will inform others of this problem so they can avoid the danger and frustration of dealing with Hyundai.
Tl* the contact owns a 2007 Hyundai Sonata. While operating the vehicle with the front passenger seat occupied, the front passenger air bag sensor light illuminated, which indicated that the air bag system was turned off. The vehicle was taken to the dealer where it was diagnosed that the air bag sensor was faulty. The sensor was replaced, but the failure recurred. The contact also indicated that the seat belts randomly activated while operating the vehicle. The cause of the failure was not diagnosed. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 36,000.
Re: investigation seat belt buckle electrical malfunction NHTSA action number: pe14023 NHTSA closed this investigation 12/1/14 on the condition that Hyundai would extend the warranty to 15 years and 250,000 miles for this repair. Per the letter attached to the case I contacted Hyundai today to get reimbursed for the expense related to this issue ($380.75). I spoke to two different reps at Hyundai and neither had any idea what I was talking about. So it's been three months since this case closed and Hyundai is not honoring the new extended warranty.
