Turn Signal problems of the 2001 Nissan Maxima

I was traveling on south bowens mill rd. In douglas GA when a vehicle that have on their turn signal involved me hitting the back of her vehicle. There wasn't much damage to her vehicle but my vehicle was damaged severely. The airbag should've came out but didn't. In 2015, I received a notice from Nissan stating that there was a recall on Nissan airbags, so I immediately took my car to the Nissan dealership in tifton, GA. I'm not even sure if they replace the defective airbag or not because the dealership was about to close when they began to work on my vehicle. My appointment was at 9am and I didn't get out of their to closing. The employees was ready to go about the time they began to work on my vehicle. However, looking at the damages to my vehicle, the airbag should've came out but it didn't. I will be submitting photos of damages.
