I went to sit in my backseat to clean some things and as soon as I sat down, I heard a metal snap. It sounded like it was not tight enough, or a bolt came loose. I came out of the car and I tried again - nothing. Sat on the other side and then moved over to that side and I heard it again.

What could this be? How would I be able to take out the backseat if I need to?

Thanks!

 

My guess would be its probably loose, ive had similar instance where makes a noises you try again, nothing, try other side nothing, then go back and its there. it has not happened to me in a car but loveseats and certain benches. The problem was looseness or it could even be metal in or under the seat.
Hope it helps, Try Tightening First. There are places you can find out how to remove your rear seat or just ask here and those places also tell how to tighten sometimes.

After doing some research, I figured out how to remove the seat:

"To remove the backseat, slip a flathead screwdriver between the seat and heel kick panel and press the release tab. Both sides need to be released before the seat will lift out."

From what I am told, it should take less than 30 seconds so I will try it tomorrow and let everyone know :P
