When car goes over bumps, I hear a squeak in the back rest of Chevy sonic. Anyone have instructions of how to get into the back rest to the springs to lubricate. What is the most likely cause of squeaks in these seats?

Thanks.

No instructions on that.

This is more of a "search and destroy" type of mission.

You will likely create a few more noises trying to fix this one,

Looks like the squeak is from inside the back rest.I was hoping for instructions to remove seat cover so I can lubricate "springs" inside the back rest.

I don't know if there are any springs in there. Does the squeak change if you adjust the headrest?

No..I have not tried this and I have given the car to my son who lives in near by town and is a student. I will have access to the car from time to time. I will ask him to move the head rest if he notices the squeak. by the way, the seat is a heated seat but the heat function does not work.

Gotcha, yeah let us know what he discovers by moving the headrest.
