It's happened twice to me and both times it dissipated by itself. The noise comes from the undercarriage it was synchronized with wheel rotation.

Being you heard it when rolling, could be something caught between the brake rotor and the thin metal splash guard...

It's just this has never happened to me before in any car I've owned. What are the chances of it happening twice within 1 year in the same car?

23k miles no banging noises like you describe. Thats a tough one too if it's not happening all the time it will be next to impossible for a dealer to diagnose.

Haven't heard anything like you describe, but the front end of my Xi makes a hellacious noise when I hit a bump. Sounds like the front suspension is going to explode, even when going over a pretty mild speed bump at the mall.

That's a common issue

My car sounds like the front is demolished every time I hit a midly bad pothole. I dont even have RFTs on anymore. Since it has not fallen apart, I assume it's normal to make that much noise.

I got the same explosive sound from front xi suspensions...nothing much we can do but spend $1000-2000 for aftermarket coilovers

had the car for almost 4 yrs, it did soften up a little bit, but still feels like hitting bombs
