Car accident. My car was T-boned on the passenger side, the side airbag did deploy. The impact from the accident pushed my car into on coming traffic and I hit 2 other cars. One in the front grill and the other in the left rear quarter panel. The front airbag did not deploy and my chest hit the steering wheel. My car was totaled and I was taken to the hospital and had 5 CT scans. The one for my chest showed a contusion which I continue to have pain from. I also had neck sprain or strain and had physical therapy to assist with the pain. When I was released from the hospital ER I was taken to the lot where my car was towed to get my belongings and took photos of my car. The photos show where they cut the side airbag out and the broken window. You can also see the front airbag did not deploy. I believe the insurance adjuster inspected my car after it was towed. …

For no reason, the driver-side airbag light has come on (and stays on) in our 2-door 2012 Hyundai Elantra. It puts our daughter and son at risk, as the two drivers of the car, because the airbag may be defective and not deploy in the event of an accident. That is unacceptable. This is an auto-maker safety issue, and the consumer should NOT be responsible for having to get this repaired on their dime. Yet everything I read online is other Hyundai drivers have gotten this and the dealers are gouging them on the repairs. We will take it into the dealer, but in no way, shape or form should we have to pay for this repair! Please pay attention - many Hyundai drivers are reporting this same issue online, even if they are not reporting it directly to you at NHTSA!
We purchased the four (4) weeks ago. On July 25, 2021 about 5:53 P.M. My step daughter was driving about 10 miles per hour making a left turn and the driver and passenger airbags deployed without a collision or impact of any kind. I contacted Hillsborough County Sheriff and we after inspection, the airbags deployed and the seat belts were locked. Therefore, we had to park the car at the Hillsborough Sheriff Office, located at 7202 Gunn Hwy, Tampa, FL 33625, Phone number [phone]. As per the officer advise we could not drive the car. The dealer has been notified of the incident. We can be reached at [redacted]
Airbag light came on for no reason. Took the car to the dealership. Diagnostics test revealed faulty airbag control module. Dealership recommended replacement of the airbag control module. The cost of replacement is $1,042. Hyundai warranty does not cover the airbag control module after 5 years / 60,000 miles. I am concerned about this as this is the basic safety feature of the car and the cost of replacing the unit is prohibitive. I'm also concerned about the fact that the essential feature such as airbag control unit can fail for no apparent reason.
