Anyone else have this issue?

When driving (accel and braking) there is a popping feeling from inside drivers seatback lumbar area.

 

Yep same here, its a common fault. I lowered my lumbar a bit until the point where the popping stopped. (about half way)

 

Not sure how long it takes, but it more than likely will be breaking. My car is on its second lumbar support. Now that I am out of warranty if it breaks I will have to self engineer a fix. Dealer pretended that it is very rare for it to happen and yet my car had a prior replacement under the first owner.

 

If you do a site search for 'lumbar' you'll find that this issue has been discussed here a few times. Here's one example of what a site search will find.

 

Mines doing the same exact thing. I have to take it in and get it looked at. It's annoying
