About two months ago my wife was coming home from work in the sorento sxl when she started hearing a banging coming from the drivers side front suspension. She parked the car when she got home and started using our backup. I took a look at it and sure enough it wasn't just some suspension wear, the Nut that holds the strut to the strut assembly had backed completely off and the strut was bouncing free inside the coil spring. I was lucky that we caught it before it destroyed all of the threads on the strut and I was able to pull the strut out of the car and re-assemble the strut. I did have to buy a new strut mount assembly that goes on top of the spring. Just a heads up. If you hear any kind of thumping up front, look into the strut assemblies.
