Rear End Noise - 2006+ Sonata with V6 engine
 

Just incase no one knows!.

In some other Hyundai Forums there is a lot of talk about rear end
noise (ka -thump) when
you hit bumps. There is a fix out there and the dealers know about it.

They will not call you unless you complain about it. I have not see a
TSB yet. I bought a 2007 SE with 3.3L engine and I had the problem. The
kit was installed and the problem is gone.
